![]() Why is it necessary to specify the -pix_fmt, as I thought all the 422 profiles defaulted to yuv422p10le and all the 4444 profiles defaulted to yuv4444p10le. FFmpeg added support for ProRes in october 2011 which made my life a little easier. So with this in mind is it better to miss out the qscale command? ![]() If you want a different compression level, you're supposed to choose a different profile, rather than change a quality setting with the qscale command, as this may result in a violation of the standard, and have the potential to cause playback issues (particularly with hardware decoders). I have seen people saying that ProRes is a profile-based codec, meaning that when you select one of the profiles, it does a fixed amount of compression, defined in the spec. at 20:45 Probably this codec will never be implemented in ffmpeg because of copyright. You do not mention anything about it, the version, or the operating system you’re on. I have read that the qscale command is not needed, and a user can just select a profile which will define a standard bit rate (for LT this is 102 Mb/s). at 20:39 It’s also entirely possible for your specific ffmpeg build to not support it. ![]() With this in mind is there any point in selecting a Prores profile other than ProRes 422 LT? The reason I say this is because the LT profile has 102 Mb/s, which exceeds the source footage from both cameras. For 4k footage, the Panasonic records at 4:2:0 8-bit at 100 Mbps, and the Gopro 8 bit 4:2:0 at 78 Mbps. I have a Panasonic G85 and Gopro Hero 7 black which I used to shoot 4k in. ![]() I am trying to understand how to use Prores Kostya with FFmpeg, and I have a few questions regarding this:
