Duuuuuude this has been the most simple yet informative explanation about this subject I've ever seen. Either i wasn't paying attention before or wtf but this made so much sense! Subscribed
Appreciate it! Always happy to hear that the videos make sense and are not confusing haha. Hard to tell sometimes when you make them! Look forward to seeing you around the channel!
Completely agree. 12:1 on my BMPCC4K for everything and never had a problem. TV episodes, commercials, & TH-cam - all 12:1.
Pretty incredible that it's still that good at such a high compression rate
If you do 12:1 once you edit it then is it also faster to edit than something shot in 3:1 or 4:1?
@@rccpromotions 12:1 is actually more resource intensive on the computer than 3:1. If you plan on doing heavy grading or Fusion nodes, then go for a lower compression ratio.
@@MichaelDeVowe okay so 3:1 creates a larger file size but is easier and faster for the computer to edit?
@@rccpromotions Exactly.
I have been trying to find good videos on this topic. I have watched about 10, and your was by faaar, the most clear and well laid out. Keep up the awesome work man!
Appreciate it! It's nice to hear that all the information is coming through clearly. It's always hard to tell if there was enough explanation.
Feel free to let me know if you have any more questions! Love your video too btw!
I really appreciate you making these BMPCC4k videos. I feel like after the 6k went out everybody kind of just ditched the 4k, even though (in my opinion) it's still well, well worth the investment. Awesome stuff!
Appreciate it! I'm glad these videos are still useful for everyone! Honestly, I think the p4k has a little bit more value upside than the 6k. Hope yo see you around the channel again!
Btw, love your content! Nice 2020 reel. I might have some projects we could link up on in the future, hard to find a good vfx artist!
@@FrameVoyager Hey! Really appreciate it! Feel free to drop me an email at jjlawsonvfx2@gmail.com any time! :)
And yes, I totally agree. The Pocket 4k is a powerhouse with it's adaptability and phenomenal price. When you consider media storage especially, 4k files are for more optimal than 6k, and I am of the belief that 4k is more than enough to shoot a movie, tv show or any other type of media. It's all about the image quality over the pixel resolution, something I wish more folks would acknowledge sometimes.
Great video, and also I like how you've arranged the frame and the softness when you're talking in the room, colors depth it all looks soft and excellent. Oh and you got the Beethoven hair, look at the famous portrait of him, it's exactly the same haha
Appreciate it! And I'll take that comparison as a compliment haha
that was very helpful, thank you! I opted for the 4K instead of 6K, and getting it in a few days. It just fits my workflow better at this time and you can’t beat the price! Just subbed, here before you hit 1K :)
Appreciate it! Glad this video was helpful! You'll love the 4k, such a fun camera to use. Look forward to seeing what you film. And thanks for the sub! Been awesome to see the Frame Voyager community grow!
This was class! Cheers. I just upgraded to a BMPCC4K from a canon m50.
Appreciate it! It's a big change but it's such a great camera when you finally get how to use it. Looking forward to see what you film!
These videos are coming out just in time I got my bmpcc4k 🙏 keep it up!
Awesome! Look forward to seeing what you film with it! Hope the videos help!
@@FrameVoyager they help a ton 👌
If you are interested you can click through the video on my main channel, the video was filmed entirely on bmpcc4k and edited in DaVinci Resolve
(it is in Greek you won't understand anything haha) .

Nice!
Thanks. Clear and straight to the point.
No problem! Hope it was helpful!
Thanks man, appreciate the video! Big help in understanding the difference 😄
No problem!
Thank you for this very informative video, it helped me out and I appreciate you :)
Glad it was helpful!
Super helpful! Thank you!
Fantastic video as always!
Q: do you have a video about the settings for filming in 4K? (beginner question)
Have a Productive and Healthy Day!
Very informative thank you!
No problem at all;
Nice video...! Well laid out ;)
Appreciate it!
I think its worth noting that for sports or action scenes people may want constant quality (subsequently larger file sizes) and for more still shots without a lot of movement constant bitrate is probably fine (like you said 12:1 for this YT video looks killer). easiest way to make a quick decision on the lot
Totally agree. It's really that flexibility that BRAW gives you with the codec settings that's just killer. It helps you in any situation and I think there are more flexible settings coming in this new update!
great example thank you
Great video!
Appreciate it!
Would love to hear something about file sizes. Like you did in your BM 6K Video. How big of a file is 1 minute of recording for each of the bitrate settings?
Good video and good channel.
Appreciate it!
Im going on a road trip and want to capture my trip and do some basic grading, what woul dbe better for me? ill have 2x t2 drives, ill be going out to film for a week. Want good quaility but not massive file sizes.. any suggestion pleasE?
do you know which ssd allows braw constant quality, constant bitrate, 12:1 and up to 60fps? Basically whats the best ssd for multiple record options with the 4k?
Great tips
Glad it was helpful!
So the BMPCC OG does not have the firmware of RAW from 2019 or did they add that to the OG cameras as well?
I've heard constant quality is best for shooting green screen footage. Is that true?
Hmm on my last video i rendered from sony vegas at constant bit rate 50.000.000 bps
Its that ok for 4k?
Or its the best for my type of video? I rlly dont have problems with the size
the size of the video was 1 gb which seemed very small to me but I assumed that it is because being vr it has a lot of black spaces
Should also mention that the word codec itself comes from COmpression DECompression.
This BM Raw drives me nuts.
I bought my BMPCC4K with firmware 6.9.1 and edit in Resolve 15 because my old Mac Pro doesn't run higher versions. RAW recoded on SD cards was running fine in R 15.
I then bought a Samsung T7 usb-c drive to be able to record 3:1 bitrates in raw.
In order for BMPCC4K to properly recognize and record on the drive I had to upgrade the camera firmware to 7.3.
Now Resolve 15 does not see my raw files anymore athough I can play them on the camera.
What exactly is going on here and how can I solve the problem?
On the BM website I could not find anything about any compatibility issues.
My man, you are awesome!
Appreciate it!
@@FrameVoyager well deserved, friend. Btw do you know by chance what are the best settings for sigma 16mm on bmpcc 4k?
@@altergeist5581 hmmmm, I guess it would depend on what you're filming?
@@FrameVoyager short films and music videos. What do you suggest?
A constant bitrate of 5:1 / 8:1 probably a good range!
Nice info but when I use the constant quality O5 then the storage card 128gb shoots up to 90 mins but when I use option O3 then it's 13 mins on 128gb, any idea why please.
depends on what is in focus I guess? I'm doing another video on this here soon to expand upon it so keep an eye out for it!
Do you know what things you get or what you lose when you go from 12:1 to 8:1 to 3:1 compresion? i meant what can you do in a 3:1 compresion that you can not do in a 12:1 compresion Braw?
You lose information when you compress essentially. This can be ok, but when there is a lot of movement or small particles, etc. in the shot you may want that extra bitrate as it gives you a cleaner image. I made an update to this video that gives a little bit more clarity
Nice video
Appreciate it!
I actually always film in Q5, it's a bit unpredictable with file sizes at times, but i learned live with it. Do you have examples for scenes were i should bump it up to Q0 like filming in low light maybe or scenes with higher dynamic range?
Hmmm... Clips besides the ones in the video? I would say something like this video example would be good (scuba diving shots all shot at Q0) --> th-cam.com/video/JCPyu50teS0/w-d-xo.html
And maybe this video (that one sunrise timelapse in this was at Q0)--> th-cam.com/video/Cd20TlT5F0o/w-d-xo.html
Honestly anything that has a lot of movement in the shot should be at a higher compression rate. Think confetti or bubbles or fine detail stuff as well as darker or over exposed environments that you just absolutely need the shot to work. That's when I would use it, otherwise I rely on constant bitrate and change it based on the situation.
Hope that makes sense! Have another video coming out this Friday that has a ton of shots that were on Q0
@@FrameVoyager Ah ok, i thought u meant that this was the difference between Q0 and 3:1, i misunderstood that. Thanks for clearing that up, gonna try that out next time im in a fast paced Environment or low light
@@sold-productions oh yeah, the difference really is just the bitrate. Q5 in most situations will work great! But Q0 for me is when you need to get a good shot and you can't screw it up. Hope that helps!
Did you use the T5 or the T7? I see description says T6 link goes to T7 lol. I’m looking for the most reliable ssd for 6k 50 or 5.7 50
T5, that's odd it goes to a T7. Thanks for letting me know I can fix that now.
@@FrameVoyager no problem lol
Еще очень важно то в каком формате мы сохраняем видео .И для youtube в том числе
Google Translate:
Дать согласие! Это также очень важный компонент для качественного отснятого материала. Моя камера всегда настроена на «пленку». Спасибо за просмотр!
So basically to get the most absolute best quality (without caring about file size) the best option is Q0?
Technically, yes. It will always insure that you have the correct bitrate for what is happening. With a range of 110 - 274 MB/s vs 3:1 constant at a bitrate of 183 constant. I do find that constant bitrate works fine as well as long as you adjust it for what you are filming. The more complexity, the more bitrate you should be using. Constant quality really just makes it easy so you don't have to think about it while doing it. The tradeoff is that you don't really know how long you'll have to film because of the constant fluctuation of the bitrate. That's why I typically use this in tricky situations like scuba diving because it's hard to adjust settings constantly while you try not to drown! haha
@@FrameVoyager Thanks a lot for actually replying. I basically learned everything about the P4k from you. One of the Best channel on the tube. Appreciate all the help 🙏🏿
@@booneybravado not a problem! Love getting questions. Appreciate it! Always cool to hear how the videos are helping others especially when you feel like it doesn't 😂! Hope to continue to see you around the channel!
@@FrameVoyager Trust me, you have no idea how much you helped me I literally had zero knowledge of anything camera related at all and decided to make the P4k my first camera to learn with 😂 bold move but I’ll be making a impact soon 😏
@@booneybravado awesome! I will say, it's a really great camera to learn on! Look forward to seeing your work! Feel free to comment anytime with questions or dm me on our Instagram page too! Good luck!
what was the reddit sub?!
I search the whole internet for how to shoot uncompressed on bmpcc4k instead of constaquality or constant bitrate and found nothing......
You can't. RED has a patent on recording uncompressed RAW internally unfortunately
@@FrameVoyager Damn...so the best quality in bmpcc4k is q0?
3:16 if you're in a rush :)
It's irritating watching you read from a teleprompter :/
Well then don't.😂 Highly technical content I try to make sure is accurate. 🤷♂️
What a weird comment. He still barely sounds like he's reading a script, unlike 90% of youtubers who sound like a robot that's trying to sound like a local news reporter.
