If your definition of "uncompressed" is the form the video is in right before it's turned to photons by a digital display, the closest I see in the ffmpeg -codecs list are -c:v r210, r10k, v410, v308, ayuv and v408. FFmpeg is rarely built with every possible encoder enabled. ![]() You might want to run that command on your own machine to see what your build of FFmpeg will support. The following POSIX command¹ gives you a list that mostly² matches what we discuss below: $ ffmpeg -codecs 2> /dev/null | grep '^.EV.S ' | grep -vE 'bitmap|image' The raw data rate of 1280×720p video at 24 fps is very nearly equal to that of your stated 1024×768 at 29.97 fps goal, so my results should be a pretty good guide to the data rates you can expect on your footage. I'm going to anchor this discussion with the 720p HD version of Big Buck Bunny, since it's a freely-available video we can all test with and get results we can compare. There are several ways to get an "uncompressed" AVI out of ffmpeg, but I suspect you actually mean "lossless." Both terms have a fair bit of wiggle room in their definitions, as you will see.
