Sony A7S III Video Quality Test. XAVC HS vs. XAVC S vs. XAVC S-i
ฝัง
- เผยแพร่เมื่อ 27 มี.ค. 2021
- The Ultimate Sony A7S III Video Quality Test. In this video I compare every single codec and frame rate that the Sony A7S III has. I tested XAVC HS vs. XAVC S vs. XAVC S-i, in 24, 60 and 120 FPS to see which combinations look the best and have the most detail. Honestly, this in-depth Sony A7S III video quality test shocked me.

I think this is by far my most extensive test I’ve done so far on the Sony A7S III. I literally compared every single 4k video format combination. XAVC HS vs. XAVC S vs. XAVC S-i all in 24, 60 and 120 frames per second so you could see which Sony A7S III video format has the best video quality. Were you as shocked as I was by the results of this detailed Sony A7S III Video quality test?
![เกิดใหม่ทั้งทีก็เป็นสไลม์ไปซะแล้ว ซีซั่น 3 - ตอนที่ 66 [ซับไทย]](http://i.ytimg.com/vi/qcaUguFlwdM/mqdefault.jpg)
I did not expect that outcome! Were you surprised by the results?
Yes for sure that is surprising. And I gess you should not bay that expencive tape-A cards and plus rider if the quality is virtually identical
Yea If I didn’t have this channel where I need to buy these things to test them, I wouldn’t have bought one after learning what I did in this video. I’ve started to record HS 50M because it just doesn’t look any worse, especially for TH-cam. I think for cool grading a higher bitrate could be beneficial though - something I need to test myself.
Hey there, i see i am extremely late to this reply (i reply to every comment) i somehow missed this one and i apologize for that.
Yes i would say your assessment is correct. i have been meaning to redo this test with more random moving objects like you are suggesting. as well as i have read that it also makes a difference when you are trying to get a really good key on a green screen. Thank you for the comment though it completely makes sense.
@@TymekStolarz Did you ever get to testing how these formats hold up in grading?
No, there's not enough complexity as detecting and compressing static movement like that is done even by the simplest codec (h264). The worst I have seen compressed video go through is whitewater paddling, filmed from the cano. I guess you won't risk expensive equipment for that, but what about driving through a street lined with trees, perhaps even with their leaves blowing in the wind? It's these kinds of complex movement in all directions at once that really stretches the codecs.
I love the detail that you went into for this!
I would have been surprised if you saw any differences between these shots, so I'm happy that you didn't show any placebo effect.
I made tests with complex footage. Leaves in the wind on a rainy day. When zooming in 800% I found the S codec to be way better than I, which is what I was expecting because of the more efficient compression. What I didn't expect is S being slightly better than HS as well.
I used the FX6 and FX30 to test them.
Codecs will act differently in different situations and your setup is very easy on any codec. Try filming confetti with all 3 and you'll see the extreme condition and the real difference between the 3.
I just want to share that you adhd helped me out to the max. You are very much appreciated !!!! Seriously man
I’ve watched a few videos on this topic and THIS is the definitive one 🔥 📸 🔥
Great efforts in putting all of this information together in such simplified format ! Thanks a lot :) , totally appreciate !
with such a static shot it is expected to percieve no difference. You should retry the test with a very moving shot like leaves or confetti. That is where Long-GOP compression falls apart. It has nothing to do with sharpness.
I was thinking of leaves but i thought it would have been difficult to compare each directly. Which is why I thought adding the repeatable movement with the slider might do something, each frame being different then the last. Not necessarily looking for sharpness, but anything that would tell them apart. I saw a couple other videos with leaves with not much difference either. But I will complete another round of tests and maybe a follow up video If I find anything of value
hm interesting, yea confetti would be a very busy scene. What exactly should i be looking for when i recreate these tests?
yes that was the plan. testing out scenes like that. thank you for letting me know what to look for.
I also have heard that its helps get the best key out a green screen. i think 4:2:2 also helps in that case. i will have to redo the video to test forsure.
Yes true thats why 120 fps and 240 fps in a7siii xacvs looks like 720p..
@@TymekStolarz when video will be out? I have Sony a7 IV but it will be similar, i think.
wow. thank you for all the amount of time, energy, diligence you've put into into this test. thank you.
Thank you for the kind comment :) I really appreciate it. I hope you have a good day!
Thank you for the video! To be honest, you need that data in S-I only for editing. So, I'm not surprised that all 3 modes look the same after TH-cam compression.
This test has to be redone with different subjects- I unfortunately did it incorrectly. I need busier scenes like confetti, rustling leaves, flowing water. I will be redoing the tests in the near future
@@TymekStolarz I will wait!
As someone who is switching his entire Canon production set up for Sony, this is VERY helpful! I just purchased the FX3, and I don't plan on using all the options, as they are not necessary for my work. Still having access to 4K 120p with a V60 card will save me a little $$$. Fantastic and well-detailed video.
Awesome :) I’m glad I could help and I hope your transition is smooth and without too many disappointments. Obviously there are pros and cons to each system. Take care :)
Awesome video Tymek! Would love to see the S-I vs S with some unpredictable motion. I think the compression holds well because the frame from the left is moving right. So it’s easier for it to guess the motion and estimate a new frame.
finally someone mention it. The differences are only intended when the footage is in motion, still footage is pointless to show the differences between those codecs.
Your comparisons for static subject scenarios are perfect! It's good to know that in that scenario there is no quality difference. But I think you missed the point of the all-i codec. I think all-i is almost a requirement when filming water/fire/fog (basically all elements). I'm still looking for somebody who tested this. I don't want to pay 200€ for a memory card just to try it out if it's worth it. All my recent music video scenarios had fog, fire or water in it and the long-gop compression turned the footage into mush.
Yea since release of this video I have learnt my mistake, and i've been meaning to re do the test. i was going to do leaves moving in the wind, bubbles, confetti, as well as a green screen as i heard keying is also better.
@@TymekStolarz would love that video
I would like to praise your experimentation method. Closest thing I've seen to a lab work. Great job!
Haha thank you very much :) I appreciate the kind comment. I like making these types of videos because they also answer the questions i have about the camera, but boy do they take a lot of time to shoot, organize and review, and create a cohesive video about.
Thank you very much for this video. I just got the A7IV and looked for Codec Comparison for my camera. Unfortunatly there were none which got me thinking that there has to be some for the A7siii.
Very scientific and well explained approach! I'm glad that I don't sacrifice on quality by not chosing to use CF Express since I have no problems editing XAVC - S on my computer.
Glad you looked and found what you needed! I redid some of my a7s iii videos specifically for a7 iv but hadn’t gotten around to this topic yet.
And yes especially with how expensive those cards are. Still lots of options without them.
Just ordered mine! Thankful for all of these videos,, and all others on your channel, great job 😊 !
Awesome! It’s a great camera. What did you shoot on before? And thank you, I appreciate you taking the time to comment and for the kind words :)
Such an important experiment- it answered questions that were bothering me! Many thanks!!
Glad I could help out :) I hope you have a great day!
Great in depth tutorial but please take no offense. Most cameras work like this. Image quality is the close to same across settings, especially in a controlled, well lit environment. More complex environments and different camera movements may produce different results. Also coloring may play a big factor in these settings, even tho all are the same bit depth. There are other things that could help broaden your findings and give a better perspective on the different settings. I'll be checking in periodically as I am a new sony guy.
Thanks for your video! She's very useful, I'm waiting for the video with the color grade !!
No problem! And thank you very much. I have a few other videos in the works but I plan to get to that one at some point soon.
Great test!! Love it. I just get my A7SIII. I hope you do more tests about this camera so i can learn more. Greetings from Buenos Aires, Argentina.
Thank you :) enjoy! It’s an amazing camera. I do have a lot of guides and tutorials on my channel On the A7siii! Autofocus, stabilization, memory card choice, video codec overview. If you are new to the camera I’m sure some of these might be of use to you! Also I am more than happy to answer any questions you may have on any of my videos, I reply to all my comments.
Thanks for sharing this! Great research. Was helpful as I was looking to figure out the format to use. Guess I’ll be using the slightly compressed HS version.
Thank you :) I’m looking forward to playing around with the a7 iv, and I will do those other tests as well
Great testing! I saw another test which agrees with your results- the XAVC-HS compression was as good or even better (!) than the XAVCS-I - even with lots of random motion. It seems the HS compression algorithm is fantastic…
Dude. You’re a saint. Thank you for doing this!!! Hats off my friends!
Hahaha thank you :) i appreciate the comment and im glad i was able to help you figure out what ever you needed to :)
This will save me a ton by skipping the CFexpress for a UHS-ii instead. Thanks!
Glad to hear it! :)
Shooting a static image with little varying detail is not a good test when comparing bitrates. I feel like I shouldn't have to explain this, but a large part of video compression is blending similar pixels and keeping static pixels idle from frame to frame. My point is, I can shoot this test background with a codec that is 10mb/s and 1000 mb/s and you will not notice a difference. Now shoot a tree moving in the wind at F11 with some grass below it and you will start to see major differences between bitrates.
Wow man. You went to a lot of effort. Thanks. Subbed
Haha yes, all these A7s iii tutorials took quite a bit of time to put together. Thank you very much for the support :)
It would be awesome if you make video with writing how much storage(mb/gb) all codes takes for 39s/1 min. video? And add samples to download- so we could try on own computer . Thank you so much for your work 🙏☺
h265 option has 422 10 bit and 420 10bit. If they look same again, consider how small the file size of 420 10bit and much easier to edit plus cheaper sd card. That is a win to me.
Yea thats why i always shoot in HS. i used 4:2:0 10 bit; However i've been running a lot of tests on my fully speced out 2020 imac, and base model m1 macbook pro, and the m1 actually edits 4:2:2 with complete ease.
thank you for all the time you put in!!!!
Hey there, thank you for commenting and letting me know the time i put in is appreciated haha. Take care and have a great day :)
It’s about the movement of camera and things. Water sparking, tree leaves, etc - sharpened is a different Category
Yes i learnt of this mistake after creating this video. i have been meaning to make a follow up video. doing the tests again.
man this is insane amount of work!!! thanks a lot for sharing. You deserve a sub and a like
Thank you! I appreciate the kind words :) I hope you enjoy the rest of your day
Thank you for your sacrifice and doing this.
and thank you very much for the kind comment :)
Difference between xavc s and xavc s-i is evident when there are fast moving trees with lots of leaves .. I found the difference when I was shooting from inside a car while driving down the road with lots of trees around
Yea it’s something that I am going to be testing again in a follow up video. I want to test leaves, trees and a green screen. I just thought by using the slider it would introduce enough movement, I just wanted to be able to have the exact same frame that I could Compare against each other, which the slider could provide and moving trees and leaves won’t.
I love your videos. Thank you so much.
Need the color grading to make my full judgement! Great video tho! Keep up the good work!
Thank you! Yea I’m still passively working on it, not testing it directly but experimenting with the codecs when I shoot other stuff. It’s really difficult to tell the differences. But I do plan to do a formal test video in the near future.
Have you tried to color grade and change exposure of the footage? I think lighter codecs will have than more artifacts than more adjustments you doing, say changing white balance, push shadows up and so on...
Wow! I am surprised. Didnt think, that I could use Codec S for everything (without a loss of image quality)
Thank you for the tests and I hope to see more content for the Sony A7S iii in the future!
It seems to be that way. Personally I’ve been using HS and the lower codec since it looks the same, and you can get 4:2:0 10 bit in HS while you are stuck with 4:2:2 10 bit in S and Si. I also have tutorials on memory card tests, autofocus, stabilization and one on catalyst browse if those were something you were interested in.
@@TymekStolarz yea :)
I ve watched them already! Great Videos 😌
I would like to use HS as well, but my MacBook with M1 Chip didnt arrive yet, so its challenging to edit them
Oh great, well thank you for your support, I really appreciate it. Do you have any specific tests and tutorials you’d like to see?
@@TymekStolarz to be honest, your videos helped a lot already! The only thing I want to know more about is how to get the best dynamic range out of the A7S iii and how to use the advantages of its low light possibilities (like 12800 iso and stuff)
Yea that’s a good one for sure. I think Gerald Undone has done a few testing out all the different profiles. It’s a little more technical then I have the expertise for at the moment
Wow. That's a lot of work - Thank You!!
No problem :) Glad i coudl help
The color grading test is where Im lookinng
Yea its a tough one, i thought i would be doing a lot more color grading at this point and i simply havent. so i dont feel as though im completely qualified to make a guide on it. however i think i try some tests to see if i can atleast see some differences. when i did this video i did try some things and everything looked the same, so i decided to leave that test for another day.
thank you for doing this!
Not a problem and glad i could be of use : )
great video very helpful!
Thank you! I appreciate the kind words and for letting me know.
For color grading, which one has more flexibility to allow you to push your adjustments more?
as far as i have been able to tell. as long as its 10 bit, it allows for the most flexibility in color grading. however the best of the best is probably S-i
@@TymekStolarz I think he's talking about the difference between xavc s 10 bit vs xavc s i 10bit in color grading
good vid thanks
Thanks for sharing. Interesting stuff. One can really spend a Lot of time on this - there is still ProRes RAW, which make these cameras very interesting to me, and like you said, grading. I have shot a lot with both the Ninja and Odyssey recorders, and there is a huge jump in colour when going up to 12 bit... Then there is Catalyst Prepare, which I use to stabilize all my handheld footage, and how Sony's various flavours of compression affect the image, vs the colour engine/ science of say Apple's Compressor... Like I say, there are a Lot of Tests that could be done...
i know, it can be quite overwhelming too dive into each factor and be able to understand how everything effects the quality of the video you shoot.
Thanks for this. Huge sigh of relief actually seeing image quality without spending all the time to do it myself. The Type-A CFexpress cards are such a waste of money =/
Haha that was my goal! But I need to redo the tests with busier scenes like rustling leaves, flying confetti etc. there should be a bigger difference between Si and the others in that situation - but we will see. Video to follow soon
Great video Thanks!
Thank you :) i appreciate the comment.
Well. Heavy test, great. But you are comparing just the resolution, but not the containing info in the containers i.e. just try to do some heavy grading (not only applying LUTs, try color changing, shoot over/under exposure), and the you (we) will see the power of the Intra codec.
Yea, unfortunately there is some value to this test with the frame rate comparisons, but as far as codecs go i am now aware i did it incorrectly, and i plan to redo the test to really test the codecs.
Awesome vid man! Would definitely be interesting to run the tests again not in terms of sharpness, but as mentioned in the comments below in terms of motion and noise performances. I recently acquired the cam and all I do is extreme low light. So far I was using HS, but I think I'll be using all-I, even with the massive file size. Thanks again and I just subbed :)
Thank you! Yes i really need to get on that. I have some other projects on the go right now that are taking up my free time, but a follow up test video is in my notes and on the to-do list. Thanks again for taking the time to comment :)
Which one should I go with when selecting XAVC HS 60P 200M 4:2:2 10bit (highest option) or XAVC HS 60P 100M 4:2:2 10bit (which I understand creates smaller files than the other but still the same image quality)?
Was wondering if you could save half your space shooting the lower bitrate on HS instead of S and I was stoked that you tested that! Thanks for the video!
I almost didn’t test it! It was something I just thought of when I was shooting and I’m glad I tested it as well, as it’s what I shoot in most of the time now anyway lol. That and the fact that you can shoot 4:2:0 10 bit makes HS probably my favourite codec.
YES YES THANK YOU FOR THIS
LITERALLY JUST WANTED TO KNOW WHICH ONE HAD BEST IMAGE QUALITY OMFG IDK ABOUT EDITING CONVENIENCE MY COMPUTER SUCKS AND I HAVE TO MAKE PROXIES FOR 4K FOOTAGE NO MATTER WHAT ANYWAY
Not a problem :) glad i could help!
Fantastic video! Did you do more tests in terms of color grading or anything else?
I'm keen on trying to save file sizes with 50M HS 4:2:2 vs 140M S 4:2:2
The only problem I see is a lack of 30fps mode on HS... I don't understand why Sony did that...
Thank you :) and o I haven't yet :( its in my video idea notebook but i haven't done anything with it yet - But its on there and i want to get it done sooner then later - just have a few other projects on my plate.
Yea that seems very strange to me that they didn't include 30p. I dont use it so i havent looked into why they did it.
Very very interesting, thank you
Yes I was quite surprised with the results. Thanks for watching and for taking the time to comment :) I really appreciate it.
Please complete the next video in this series you mentioned that will test whether XAVC HS & S-i hold up better in grading than XAVC S. So interested to know as this video showed no benefit to the footage. Thanks for your insight!
Hi there and im very sorry about the late reply - Yes i really need to get on that. i've taken a small break from making vidoes but i will be getting back into them soon.
Thank you for a very helpful video, and you save me for al lot of money :-) I hit the sub button.
Glad I could help :) and thank you so much that is very kind of you. I hope you have a great day !
A color grading video would be awesome. If I can shoot with lower bitrate HS and literally get the same performance that'd be incredible for storage.
Forsure I agree. I’m going to have A LOT of time on my hands really soon here to get a lot more videos out including playing around with color grade and try to find some other things that could use explaining on the A7s iii
@@TymekStolarz Looking forward to it!
I have a suggestion for one of you next videos about memory cards. Could you just say bay this exact memory card and name it and it will be just perfect for Sony a7s3, so many options and so many other things to think about so it will be much better just to know what exact card to bay and not overthinking this issue. Great videos!
I do have a memory card video on my channel that I made a little bit ago, but it is more general instead of specific, so I will consider making one like you suggest. However I will tell you that the Sony V90 card is good - it’s just a little thick because of its “tough” rating so it takes a while before I was able to get it to move in and out of my A7s iii. And it happened with 2 copies. The other one that I’ve heard a lot of good things about are the prograde v90 cards, and I have the v60. I would defiantly stick with v90 though.
@@TymekStolarz My idea could be not just about cards (thanks for recommendations) but about the hole kid, like for the start I recommend you this exact lens, this exact memory card, this second battery (if not from Sony) etc. For middle ground kit is this list... and for ultimate TH-camr kit I recommend this list. It's not easy to compare all the market but at least we will have you general ideas. Could be usefull, at least for me
Ah yes this type of video would have a little more to talk about for sure. I will definitely start to do some research to put something together for a video one day. Sorry about the late reply, for some reason your comment went to my "hold for review" folder and i didn't see it until now.
@@TymekStolarz No problem)
i plan on renting some other cameras and running a bunch of tests over a few days and making videos on my findings. once i've amassed that info it will be easier for me to make a summary video talking about the different tiers of equipment people could buy.
Thanks, that was a lot to compare, I wonder if it has to do with color grading and the ability to push and pul colors and contrast, and still retaining image quality. Lastly would love to see a image quality test with XAVC HS 4220 10bit Compared to the 4222, Currently upgraded my ram to 32 gigs and XAVC S 4K @ 120fps is uneditable... I am now converting to proxies to see if 120 is editable, but it was not prior to me upgrading ram. Trying to find the minimum PC thresholds for editing and optimal production/productivity.
haha it sure was, lots of footage to go through - i am working on a video on right now comparing a whole bunch of stabilization options in different camera movement scenarios which has even more combinations to test and compare. they take a lot of mental bandwidth to put together lol.
Yea definitely it has to be associated with color. i was actually going to include a test in this video but when i shot a 8 bit and compared it to 10 bit, no matter how extreme i was with color shift or saturation they both looked the same, so i think i need to do a little more research to find a better testing method.
i dont think i would make a whole video but when i have some time i will do a test and get back to you - my suspicion will be that image quality wise, they will look the same but there could be some color grading improvements.
anything less than 32g i can see slowing things down, but i think it also has a lot to do with the graphics card as well. proxies though is a good temporary work around though. one of my first videos is testing the performance of my IMAC with 8, 32 and 64gb of ram with various photo and video editing software to see how much i can overload the computer b4 it starts to slow down. things might be a little different on a PC but there might be some info that could be useful for you.
I think the flaw in this test is that you are comparing frame vs frame. In reality you should be comparing a sequence of frames (eg: video). the only difference SI has is that it doesn’t “leave out” any frames creating a “smoother” look. SO you need to test this with various scenes, with different lighting conditions, with different subjects, etc. Good work though
Yea since this video has been posted I’ve thought of better more accurate ways to test the codecs out more thoroughly, though I think this test still has SOME value just far from the full picture of what the differences are. I do plan to make a follow up video that’s marked in my note book, I just haven’t gotten to it yet but I think I will sooner than later: I was thinking tree branches, a stream of water and a Green screen for scenes to test
@@TymekStolarz I think you would want to test it with some fast action. That's where the biggest difference would be between SI and the compressed formats. As well as really tough lighting conditions. Glad to see you are putting in the work!
Thank you for the video. I have adobe premiere pro 2016 model, and it won’t run the s-i, neither does davinci resolve 17.
hi there and im very sorry about the late reply - that is very strange. unfortunately i dont have either program so i cant test it out myself. your only option might be to reach out to support for the programs and ask what can be done.
@@TymekStolarz the codec support is in the later versions only. I think the PP version I have is old to read the codec. Also, it was one time purchase so I don’t know if I can update the software.
@@ruchirsajwan ah that would make sense. and i dont believe you can. thats benefit with the subscription models is you always have the most recent version of the software. when you buy a copy you forever are stuck with what ever features it came with.
In short, I spent my money on nothing, buying a CFexpress memory to record in XAVC S-i, how sad.
What about putting the videos to heavy grading?
So grading was originally supposed to be part of his video, I had seen a similar video push the colors for a similar scene. Which is why I used colored boxes and books. But when I pushed the scenes, they all looked the same. Even in 8 bit for some reason. So it’s something I decided to test in a later video.
@@TymekStolarz I have seen 2 popular TH-camrs not happy with sony colours especially in slog (DSLR VideoSHooter & Camera conspiracies) Sony probably just cripples the lower end cameras so as not to compete with their more expensive options. Also, Philip bloom showed heavy mushy in-camera noise reduction when you go up in iso. These cameras are amazing but obviously slightly crippled as well. this is overall one of the best information videos on SOny a7siii and fx3. Big thanks.
Yes i've also seen people not overly happy. But i personally love this camera. the image it creates is amazing especially with quality glass. more then enough power to create professional videos. maybe not movies, but web commercials, product videos, weddings, etc. And thank you for the kind words, i appreciate it :)
Great video. I recently purchased the Sony A7IV but cannot view 4k 10bit 4.2.2 files on my PC. Can you suggest what I need to do to fix this issue? Thanks for your help!
thats the unfortunate part with 4:2:2 specifically. that is one of the reasons i shoot in 4:2:0. but otherwise you need to download another video viewer. Catalyst browse will play back all videos, as well as it has some additional functions.
Great details. After all that, what settings and picture profile do you tend to use?
Thank you :) for talking head recordings, i'll use the XAVC HS, at the lower bitrate of 50M and 4:2:0. For basically everything else i use HAVC HS, 100M 4:2:0. PP i have set to off for the time being just because im not too confident with color correction and grading just yet so i avoid Log; however i havent updated my A7S III just yet but i think i will soon to try out S-cinetone.
@@TymekStolarz Hey Tymek! Just wanted to let you know that as long as your exposure (middle gray) is metering 0.0 and your white balance is correct, SLOG 3 needs practically no color correction whatsoever, Id highly recommend Phantom Luts for some great color and film emulation. Definitely tackle shooting in SLOG 3. 640 to 1600 or 12800 in lower light scenarios. The highlight roll off, dynamic range and color tones are very much worth it. Cheers!
Hey there :) Yea i REALLY need to dive deeper into Slog 3. i know there is such a huge part of the camera that i am not utilizing. i need to do some experiments and testing but i just have so many projects i am working on at the moment.
Thanks for the comment and encouragement and i WILL get to testing shooting in SLOG.
Take care :)
@@TymekStolarz I've been using the same for a few videos now and I like it. I haven't been brave enough to try slog3, even though a lot of people like it, due to being afraid I would over expose or something and not even know it till I got to post. Thanks again!
Very helpful comparison, thanks for sharing! One question, do you by any chance know if there is a difference in battery life in the different modes (xavc S/HS/S-i)? Thanks
Thank you :) that is a good question of which i dont actually know the answer to. however i think codec would be generally the same, with more battery life differences coming from the frame rate and resolution
@@TymekStolarz Yeah, that would make sense
Hello I wonder if you can answer this question I just purchased a Tough CF express card Type A 160gb 800r 700w. When I set my A7S3 to xavc Si the 120fps option is not showing any ideas thanks Dave.
Hey there Dave, unfortunately xavc Si 120 only works in s&q mode, and not regular movie mode. So 120 4k Si should show up in the s&q settings
@@TymekStolarz Thank you very much you gave me a clue where to look and it’s working fine now, thanks for taking the trouble to reply much appreciated
Glad I could help :) I reply to every comment so feel free to ask any questions you have, I will answer them all to the best of my ability :)
very nice efforts taken buy you but sorry to say u hav shooted on still objects . plz repeat this same test of moving water or ripples in water u will what differece there in hs and s . I think other experts watching this video may agree with me. In short repeat test with compex action videos
Yes this video has to be return - I will be doing so in the near future
instant subscritbtion💫💫
Thank you very much :) much appreciated
But everything you did was in a controlled situation with all the lighting and composition set up. What about all the codecs in uncontrolled lighting outside and low light.
Add handheld to the above.
The biggest mistake I didn’t do was test the codecs in situations where the negative effects of compression could be shown. This is situations like confetti flying in the air, branch’s of a tree moving, falling leaves etc, where each frame of video has lots of movement from different sources throughout the entire frame. That’s something I have to redo and update this video with
@@TymekStolarz yeah, true that would be better. Also do vlog tests on all, I would like to see how the difference differ in Ibis department. It is funny that I want you to do all that when I already own a7Siii and could do all those tests myself 😀.
@@kapilesh14 i do have a video testing the different available stabilizations (IBIS, active, catalyst browse, final cut pro) - th-cam.com/video/BEBUiaGeg34/w-d-xo.html
Great video but do you test the crop mode 4k with full readout of the sensor and 8k with external recorder downsampling to 4k? thanks
Hey there, I’m not quite sure what you mean. As far as I know the A7siii can’t shoot 8k external or internal. And all the 4k modes are full sensor read out. 4k 120 is true full sensor readout when it’s 1.1 times crop. All other 4k modes have a slight down sample from the full A7s iiis sensor resolution
@@TymekStolarzYou are right I just receive my A1 so I make this mistake but I really like your video your explanations are clear. But I really think the 4k execept 120 are pixel binning view video of G.Undone
hm you might be right, but i could have sworn he said the A7S III does not pixel bin - i may be wrong though. either way its still the best image i've ever seen. ah yes the A1 would be the one with those features. a beast of a camera that one.
@@TymekStolarz I will happy to share my review in 2 weeks Thanks again
Please do! Would love to watch! Take care :)
Will i have any problems editing a project with both h.264 and h.265 in the same timeline?
Also sub’d just bought this cam and still figuring it out
I was pretty sure that there would be no issues but i just tested it out and stacked XAVC HS, S, and S-i all on top of each other and i was able to flick between all three during playback without any issues.
Thanks :) I have a few A7S III tutorials that should be of some use to you - also working on a very in-depth stabilization video that will be out tomorrow.
@@TymekStolarz great! Wasn’t sure if my computer would have trouble editing or exporting the different codecs. Do you find hs harder to edit with? I know its more compressed? Im in the process of getting a new computer so i cant test any of these my self properly.
@@TymekStolarz great!!!
GOP VS all intra for fast movement, maybe outside with a subject? some people insist the ALL intra is best for motion, but based on ur test, will we see any difference at all? mainly not about the sharpness but how it actually feels, looks, frame to frame when a subject moves, like running etc? thanks
Yea this one is a tricky one. The examples I’ve heard about is like ripples of moving water and moving leaves on a tree. Lots of motion moving all around. But it’s tough to do a direct comparison that is the exact same, that’s why I thought of the test I did because it was controlled with all the footage looking the exact same way that I could directly compare. It would be more difficult have direct comparisons. I wasn’t sure what I was looking for, not necessarily sharpness but anything that would differentiate the two. I would say this exact comparison was inconclusive, but i think there was still some helpful comparisons like Hs vs s, and 120 vs 60 and 24, and how 50M HS still looks the same as 100 HS and 100 S.
@@TymekStolarz yeah thanks. just got the fx3 and i mainly shoot sports videos, skate, parkour, running etc. i wanted to establish the xavc S as my default, or HS if my computer can handle it, but no idea if finally i HAVE to go with all intra ( which i dont want to) in order to have a better looking motion image ( not sharpness ) and if it is really gonna show eventually, and if yes how big the difference would be. still waiting for a lens i have ordered and i can't really test it yet..
Personally I shoot HS because you can get 10 bit and 4:2:0, all the other 10 bits you have to do 4:2:2 which most computers have an issue editing and with play back.
I think there will only be very subtle differences if any between the codecs, but probably for like 90 percent of the time they will look the exact same. For the example of a subject moving or running I don’t think there will be any visible difference.
@@TymekStolarz thanks!
No problem and good luck!
Which hardware should we use for 120fps h.265 10bit 422. for smooth for editing and hate doing proxy. Also h.264 422 10bit same thing. Even tho i have amd 5950x rtx 2080. Thanks in advance
It’s a really good question. - just to confirm, you’ve tried to edit with the 2080 and it’s still not super smooth for 264 and 265?
The problem that really slows things down is the 422, and not that it’s 10 bit. There are just very little graphics cards out right now that have the proper hardware to edit it properly - the only one i know is the m1 chips, even though they are integrated graphics I hear they cut through 4:2:2. I have the 2020 iMac fully spec’ed out, 5.5K CAD and it still chugs with 4:2:2. So I’ve been shooting H.265, 4:2:0 10 bit, and that seems to work fine, and I would imagine it should edit decently on the 2080. I haven’t heard anything about the new 3000 series but they might be better with 4:2:2 but I’m not sure.
@@TymekStolarz so should I shoot 422 if I have the M1?
7:13 in the chart from the previous video you showed 4k 60p s-i can only work CFX type A. But you keep repeating that it works. Which is it?
I’m pretty sure I had shown and said that 4k 60p s-I works with cfx and v90, but let me check and confirm, I am on mobile and it’s harder to review the vid.
So what i said was still true. I will repeat my reply here from that video just incase others read this: V90 cards can still shoot 4k 60p All-i, but only in regular movie modes and not S&Q - even though they are the exact same bitrate. As at least one of those modes work for a V90, I would still say there are only 2 modes that a V90 card cant shoot (4k 120 All-i, and 1080 240 All-i).
V90 doesn't work on only 2 modes 4k 120 All-i and 1080 240 all-i in regular movie modes also doesn't work on a third mode which is S&Q so only 2 and a third.
you actually cant even shoot 4k 120, or 1080 240 in ALL-i regular movie, they can only be shot in S&Q, but yes technically as 4k 60p all-i only works in regular movie and not S&Q, in total there are 3 codec, bitrate combinations that dont work with a V90 card.
Having had this card, and knowing what i know now about video quality etc. i think CFexpress is overkill. the only time i've used those codecs are for video tests haha.
How are you comparing still images for this comparison???
I just thought it would be easier to see details when they are frozen frame by frame instead of while a video is playing out.
How did you manage to record xavc s-i at 120fps?
It is only available in S&Q mode and not in regular movie unfortunately.
I think the SI is for better quality with motion details. Would you know about that ?
It is something I tired to test towards the end of the video, where I used the slider to create movement between each frame testing HS, S and S-i. I couldn't see a difference between each frame, or when it was played back in real time. But this method may not have been the correct way to test S-I. I've seen that S-i should look better for busy scenes like rippling water or an entire frame of rustling leaves. I have yet to test this though, but i plan to make an update video trying to find and test more methods to see if S-i really has any obvious visual difference.
@@TymekStolarz Yes that's what I have heard of. I am planning a green screen shooting, and was looking for the most information possible to get it right and more easy to keyed and edit. Thank you for your videos and follow up.
ah yes i also heard that all-intra compression was also better for keying green screens - i will be sure to add this to my list of tests, thanks for the reminder. i have used regular IPB compression with other cameras for keying with a green screen and i never had too many issues as long as the green screen was lit properly.
@@TymekStolarz I see at the end of the video want you mean, yes I find that too. The differences are very small. But it's maybe just me, but I see that some elements are more "profound" like the teal color of the book. So maybe it you need to make some compositing, you have more informations on color channels that can help for integration. Let's say if you shoot with green screen and some actor move fast. You want the most informations, and no motion blur.
@@TymekStolarz I'm not familiar with intra compression meaning. What is your suggestion for green screen shooting with this camera ? This is not my camera and the cameraman is not used to do greenscreen shooting sessions. Thank you for your follow up, this is really appreciated.
Any luck on how to view (play) 10-bit 4k clips on PC?
On my PC i am able to play 10 bit, the issue is whenever its 4:2:2. if you do 10 bit 4:2:0 on HS, it should be able to play back. If not, using catalyst browse will preview all video formats.
mpv player works great for me
Thank you for the heads up :)
@@TymekStolarz found a grate solution using ICAROS app thumbnails are showing now with 4k 10bit 4:2:2 and files play in VLC
Interesting! thank you for letting me know, i appreciate you following up.
The S-I looks sharper, more saturated, and "better" in most of your examples..
Hm, maybe I had just been staring at them too long and I no longer had a fresh perspective. They definitely looked the same to me the few times I’ve watched the video back.
I’m sorry but this test is useless. You must film a slight gradient like a wall and then add a load of color grading and exposure boost (these are things that happen every day during a production) , and the difference betweeen the 3 codecs will be impressing.
Yeah this video doesn’t end up answering all the questions but I think it at least answers some. I’ve been meaning to remake it though for a while with additional more applicable tests.
You'll find different results if you shoot something other than we'll lit books
Yes i plan to redo this video with more appropriate tests, of which i didnt fully understand until after i released this video.
