Hello everyone.
I process videos of 3-10 seconds in After Effects. There are many codecs in Shortcut, some of which do not support high resolution. I understand that there are codecs that are easier for video editors to work with. I have 16 gigabytes of RAM and there is material in 2K and 4K resolution, what can I do with this?
This may be a continuation of the previous topic “better codec” more CPU. I’M STILL NOT CONVINCED THAT FOR HIGH RESOLUTIONS, IT HAS TO BE H264/HEVC.
The camera 
in the review (I liked it so much I bought two, but the stabilization is poor) records in 4K in an AVI container.
Your browser doesn’t support playing this video format.
You can download it to play locally.
@shotcut 🫵🏿I’m not sure if “vc2” stands for VC-2, or is it? See how interesting:
It is widely characterized as an alternative to the latest ITU-T and MPEG video codec standard known as H.264/MPEG-4 AVC…
WMV 9/VC-1 contains coding tools for interlaced video sequences as well as progressive encoding. The main goal of VC-1 development and standardization is to support the compression of interlaced content without first converting it to progressive, making it more attractive to broadcast and video industry professionals."

I don’t know much about cameras, I’ve never had one. H.264 supports the AVI container, this codec is about 20 years old, it’s not new. H.265 is also an old codec. I don’t know which codec is better for After Effects. In the video properties you can find out what codec the video was made with.
Here is After Effects’ Importing and interpreting Footage documentation. Kind of funny that it says all of these video codecs are “uncompressed.” I suggest trying with DNxHR.
Here is the FFmpeg documentation for vc2. I have no experience with it.
The first link doesn’t work. I rarely use After Effect anymore. I’ll mark this answer as the solution.

Motion JPEG (MJPEG) 
, is computationally simple, making it suitable for low-power embedded systems that require real-time encoding and decoding.
Since video is potentially going from Shotcut to After Effects and back to Shotcut, the codec needs to survive multiple generations of encoding without accumulating loss each time. DNxHR and ProRes are probably the most practical candidates, as stated earlier. Lossless codecs work too, but have their own hurdles and compatibility issues.
MJPEG, H.264/265, AV1, etc are not designed to retain quality over multiple generations of encoding. The accumulated loss by the third generation can be very noticeable, unless high quality settings are used. But that would take more time and disk space to export that way. Meanwhile, DNxHR and ProRes are much faster and simple and “just work”.
