- Sony A7IV compressed VS uncompressed RAW
I am not going to beat around the bush here. I am changing to compressed RAW files for photos. I don't see a significant enough difference between uncompressed and compressed RAW to photography otherwise. I prefer to have the extra 4-5 frames per second in burst mode and get the shot I need.
Compressed RAW is half the file size, and you are able to get more frames per second with little to no image quality loss.
This wasn't a completely scientific review but it includes real world photos and testing and also some studio testing. It is safe to say compressed RAW will suit majority of people for many different needs.

Mate , I am a hobbyist, recently upgraded from A72 to A74. I’m obsessed with this camera. Your content is helping me so much. Thank you, much respect 👊
I have a A7II and thinking about the switch. Is it worth it?
@@TechCrazy definitely
Straight to the point and very helpful! Also, your photos and color grading are gorgeous! Definitely subscribing.
Thanks man, your channel is really helpful for me, especially since I got myself the A7IV! Really enjoy these short A7IV tips & tricks, this was one I was about to test out myself, but I guess I don't need to do this anymore, I'll definitely be shooting more in compressed RAW from now on!
Thank you for watching. Certainly test it yourself if you want to see it too. Wouldn’t hurt
@@JasonMorrisphotocinema I've heard that the difference is most noticable in extreme dynamic range situations where you really have to push the setting, but that's kinda what you did with that underexposed shot, and that looked perfectly fine to me!👍🏻
Love the Laowa Shirt!! Your channel is gaining momentum this is the 100k year!!
Hehe let’s hope Steve. You’ll be there with us soon
Hey Jason thanks for the video. I shoot lossless compressed I think that's a good middle ground. As far as pixel peeping goes I don't think you will see a huge difference but when it comes down to editing photos I think that's where that extra info comes into play with how far you can push and pull the colors. Anyway great info keep it up 🤙
Thank you so much Jason! I've been confused why my frame rate wasn't as fast as advertised, and switched it into compressed (just like you did) and just felt like such a dummy lol. You're right, the difference between that many frames per second versus a minuscule image quality difference has a clear winner! It's compressed from now on for me!
Loving the a7iv content!
Clear and persuasive info. Will try same myself. Appreciate more photos content in future posts.
Loved this one! Good info and interesting 😌
Thank you sir. Changing my settings now. Always top notch brother!
Thank you for watching
I learned this with my A7RIV. The compressed RAWs are a must for that beast.
I’m with you here. My bro went through my a7riv and changed all my settings, and I totally freaked out when I saw I shot compressed for a shoot. I yelled at him…but he was like…dude there’s no difference it’s just math. He’s an incredible photographer and software engineer. Once I actually looked at the files I couldn’t see a difference. Really makes a huge difference on work flow and storage. And rather than getting 1k photos on a 128 I know get 2k
Hi Jason, Thanks for the excellent review! Do you happen to have a trick to previewing the A7iv ARW thumbnail images directly from the SD disk? The ARW preview files aren't showing which wasn't an issue with the A7iii. BTW I'm working on a Mac which doesn't support this feature as of yet. Thanks and be well!
Thanks for the vid, I was on the same boat for years but when I added A7c to the kit, it was set to uncompressed and I opened this can of worms again. Back to compressed.
I’m really starting to lovveeee the H.265 and HEIF formats. Could you please look into Raw vs HEIF? And maybe a video on it? I’m starting to feel like this is where the money is, thanks again for awesome content!!
Love your video, I see your video expect ratio is wider than 16:9.what ratio is it. and do you just crop the top and bottom using wide angle or use anamorphic lens? thanks
Very helpful. This reconfirms what I saw elsewhere.thanks.
You make the best content about the A7IV, also because you usually says it's good and I bought it 😂
Hahaha love it
Very helpful and informative! I've also noticed when I export jpegs out of Photoshop and I can choose between good and very good and excellent and great which all produce a different number of megapixels for the jpeg, there doesn't seem to be a lot of difference in the appearance of those files also. A JPEG that is less than half a megabyte looks very much like a JPEG that's 3 MB. I think that deserves a closer look also because those saved jpegs are what often end up filling my computer up.
Yes photoshop gives plenty of options like that which is great.
Agreed!!! Great info bro
The image may degrade some more when shooting in burst. Not sure about the newer Sonys, but I just watched a video last night that made this comparison, and the image on the a7 III goes from compressed 14 bit to 12 bit when shooting in burst mode.
Banger of a vid 💪🏻
Thank you for watching
3:13 - Duuude! Which lens/lenses were these shots shot on? They look crisp but also smooth and natural to look at at all the same time! So nice!
When I was using lossles compressed I had some problems with zooming in the photos on my Macbook Air M1. They didn't look sharp, but they look sharp on my Imac. With uncompressed no problems on my Macbook Air.
Thank you.... very nice information
If we are using a 100 mm lens on a full frame camera , at what real distance will a 1 mtr long diagonal placed rod / stick will occupy the full 35mm diagonal of frame ??
Great info thanks!
Very interesting, thanks
Hi Jason! I found the AF assist feature of my a7iv working with native sony lens but not the sigma 85 art dg dn. Does your third party lens work on a7iv when using af assist? Thanks
Only native lenses and possibly a select number of others. Sadly, Sigma is not.
The Best channel...
Thanks for watching.
Super tip Jason. Thanks
Thanks for watching bro
Great videos as always. I can not open (ARW files) shot Raw from the A7 iv in Affinity Photo. suggestions?
Because it’s new and the software may not support the files yet
Hello Jason, I recently bought the A7Cii. But I am not able to view any of the RAW images on my Mac mini M2. But the RAW images from the Sony 7IV is opening without any issue. Can anybody please help me out?
Interesting! how about long exposures for Astrophotographers landscapes shooters, I wonder if there is a difference..🤷♂️🤔
I spotted the different levels of RAW when going through the settings on day 1. to hedge my odds I simply switched to the uncompressed RAW, my shots keep coming out around 77-78mb :S
I don't shoot massive numbers of photo's so the space isn't an issue, but having the extra information is a bit of a safety net while I learn to post-process. eventually I will switch back when I shoot more and know what I am doing in post LOL.
Yeah definitely if you’re not worried about file size, uncompressed raw has to be better
@@JasonMorrisphotocinema ill be in London mid March for about 4-5days so I think I'll have to shoot compressed out of necessity, unless there are great deals on memory cards 😅 also hoping for things like lights, batteries and grip too 🥴
I have done the comparisons between the different options and even when you push the files as far as they will go, there is no difference that you can see.
Hey guys! Does anyone know if these variations make any difference when it comes to printing photos?
Good,..thank for sharing 👍🙏
Thank you for watching
I think there is a bit of a dynamic range hit on compressed Raw. I don’t know this to be fact but I’m pretty sure I’ve came across this info a couple times
That sounds about right. I found it hard to replicate these on a large scale to see a difference
Hey What lightroom preset you used, looks nice
I grade to image with my own LUTs
Is lossless compressed also 6 fps? also is there a bit depth difference?
Yes it is 6 fps.
Watching this, I have seen the difference in grain look, with uncompressed detail being more recognizable and more natural.
As it was said, it's like a difference between 34mp and 33mp, very very small and hard to catch.
Actually watching conparisons, more colors should be the biggest difference, well, as seen, nore colors do add a little of detail, that miniscule one.
What bugs me the most is tho, uncompressed grainy detail looked more natural(other yt video), I would prioritize lossless compressed if I needed spewd tho.
6fps vs 8fps or even 10fps is a difference.
I shoot raw+jpeg, so just shooting raw only may help too.
As I moved on to A7IV now, I will be happy with no limit in vurst for now, its great to know the difference however.
Big thanks.
I just use uncompressed raw for astro and time lapses where I'm going to want the most post flexibility possible.
PLEASE HELP!!... I RECENTLY DID A WEDDING IN LOSSLESS COMPRESSION FORMAT. I AM NOT ABLE TO OPEN RAW FILES. BUT WHEN I SHOOT UNCOMPRESSED THEN THEY ARE TOTALLY WORKING. ONLY WHEN I SHOOT COMPRESSED THEN I AM NOT ABLE TO OPEN OR EDIT THEM. I HAVE LATEST VERSION OF LIGHTROOM CLASSIC.
Please contact Sony for support
There’s def going to be a difference between lossless compression and “lossy” compression. Lossless is like reducing a fraction to its lowest terms. Lossy is like rounding it to much simpler but close enough fraction.
If there is a difference I didn’t see it with pixel peeping. Not enough to worry about anyway
Yeah, I shoot lossless compressed. It's the best way to ensure the data is accurate without sacrificing too much in the way of file size. I do wonder if Sony does some tinkering with the lossless compression to remove some well-known sensor noise or something though. This would at least account for observed differences in the histogram. Interesting stuff though, the whole conversation reminds me of the mp3 vs flac vs wav conversations for audio.
@@SyphriX just to piggy-back: what is the max framerate for lossless compressed? I found the compressed vs uncompressed quite striking
@@Louis87777 Lossless is significantly slower than the lossy compression. If I need the frames, I’ll definitely be switching to the lossy compressed raw format.
@@SyphriX thank you!
Thank you
Thanks for watching
Bump the shadows up all the way on some images and see if you can tell a difference.
He pulled up the exposure by 5 stops in this video. That should tell you enough
@@kressiv I said bump the shadows.
Mike Smith has a video on the a73 showing what pushing the file could look like, uncompressed is clearly better in that case. You wouldn't see a difference otherwise.
You are %100 right..
I never shoot uncompressed raw because of over load size for 2% different maybe 😅..!
Happy and satisfied with compressed and got massive result
Exactly my reason. Thanks for watching
Yeah 🤩
i Think its the same "Problem", that the A7iii has. There is not much of a difference, until it comes to long expossure....
i saw a Video from a youtuber ( i dont remember the name...sorry ), that did this Test at night (with the A7iii) ... in the dark areas you see a massive difference. So maybe it could be the same for the A7iv.
Thanks for this Video Jason and sorry for my bad english :-D.
Greetings from Germany
Pablo =)
Yes. I did see this. That’s why I tried underexposing but 5 stops and didn’t see a significant difference expect for standard image quality loss across both photos
0:30 what is this set?
But does it affect video quality?
Aince switching to uncompressed raw, i feel the loading is faster for pics when i am editing. Am I the only one that finds the editing quicker with uncompressed raw?
Julia trotti said that too
And i also felt it the other day i was doing edits
Probably because compressed files require an algorithm to run to decompress them, so more processing required.
@@SyphriX that’s exactly what I thought!
yup, you're correct. With compressed raw, your computer has to uncompressed it to view it. So having a faster and stronger cpu will help with compressed RAW files. It does get annoying though when viewing compressed photos on Lightroom especially when you have 1000+ to photos as each photo can take 2-3 seconds to clearly load even from an SSD. And when you just want to speed through it, you really can't do that. So we gotta chose either space or time.
Great video. Even though I shoot mostly video with my A7iv, I do want to start shooting stills especially taking advantage of the higher megapixel sensor. Thanks so much. By the way, could you do a short video on your preferred settings for shooting stills? Cheers.
Thank you for watching. Yes, I have to do that
This maybe the case, I have heard that processing uncompressed files are faster. So, if you have lots of files to process in post it maybe worth shooting uncompressed...
I haven’t had any speed issues either. Not the same as compressed video files
how can you even see your raw files? they won't even open.
Sony's lossy raw compression just reduces color precision. It only uses 7-bits of precision over 16 pixel horizontal stripes. An underexposed picture may only require 7-bits to encode the entire image, but the Sony compression only has to work with 16-pixels. An ideal black and white test chart only needs 1-bit of precision.
I did show some “real world” photos and still it is really hard to see a difference. I can guarantee 99% of people that own cameras won’t be full uncompressed RAW. Cameras are so good that there is little to no difference. My clients have zero idea and don’t care what I shoot on. It’s the final product that they care about and these compressed files are beautiful
I do a lot of sunrises and sunsets though and that's where you just need uncompressed raw
check in the shadows and highlights
It sounds like it's a use-case question. There's no debate about whether uncompressed files retain more data: they do. However, in situations like sports, wildlife, or events, the difference isn't so substantial that it's worth sacrificing higher frame rates. However, for studio work, product photography, or anything with a controlled set, I see no reason not to take advantage of uncompressed raw's benefits.
If i remember correctly, you lose about 2 stops of dynamic range with compressed raw and it is just a bit more taxing on your computer since it has to always uncompressed the files when viewing them. Same goes with E-shutter, you lose about 2 stops of dynamic range. I tend to use uncompressed raw when it comes to portrait photography. I'll use compressed raw on candid and event shooting as i do like the smaller files and the faster write speed. But most of all, you can't really tell the difference too much with both formats on candid photos. So I use uncompressed for my best shots which are usually my portraits. If its there, use it!
Yeah that could be fair. I didn’t see much loss with the histograms for it to be significant enough. But uncompressed has to be better
Yes, dynamic range takes a bit but if you nail the exposure, i strongly believe they're is no discernable difference until you try to shot match to another camera. Still, the extra dynamic range let's you boost that specular highlight that gives pro photos that magic sheen that you don't get with cell phones and lesser cameras. I shot uncompressed because of that but compressed for casual.
@@matrixate true that. I used to shoot in uncompressed for everything but it took up way too much SD card space and hard drive space. Lowest i will ever go for Lossless Compressed RAW is M, never go down to S and sometimes L. I do prefer to keep as much RAW information there as possible to work with but i realized that there are a lot of candid scenes I dont need to capture in the best quality.
Why don't the give us compressed raw in video
I just got the a7IV today and I might not be right but - you as a film maker - raw lossless, compressed.. won't be visible on those test charts, checking lines... isn't the point of it the same as 8bit vs 10bit video? you tweak it to crazy? go uncompressed. the test should be there and not checking sharpness. of course it's the same. this is not like comparing jpegs saved in quality 12 vs in quality 3 . maybe I'm wrong, will do my own test of course :) you do great content
I shoot compressed almost all the time, unless I'm doing a portrait to showcase the subject's eyes.
I only shoot compressed raw since I have a73. Do not notice difference.
Compressed RAW certainly is great in my opinion
The difference at 3:00 was clear, really. Is it massive? No, but it's there.
low light is uncopressed raw is better but most part so compressed work fine. A7III you can see red ring at compreesd raw when shoot in dark/low light, but t happen only if you underexpose lot. th-cam.com/video/euVGDd3S9U8/w-d-xo.html
Hard to compare a7iii with a7iv though as the processors are different etc.
@@JasonMorrisphotocinema yes but think more happens in extreme low light between com and uncompressed. If you shooting right exposure = hard see any different
You should only shoot Uncompressed when there's a lot of Dynamic Range needed in a photo
so like sunsets?
you shoot uncompressed raw so that your PC isn't doing so much work uncompressing it so you can edit. Faster editing if your PC ain't that amazing. I have a good PC and I still use uncompressed raw, I don't like waiting forever for these images to load.
Whats RAW? jks
😂😂
Uncompressed Raw has way more Details makes it look sharper and 14bit color compared to 12bit color.
