The comments of the ticket also provide a solution. You could also use `ffprobe -i <input_video> -debug 1`. There’s some documentation on that at https://trac.ffmpeg.org/wiki/Encode/FFV1 <https://trac.ffmpeg.org/wiki/Encode/FFV1>.
q2 is it true that the following command will create a file with ffv1 version 3? ffmpeg -i <input> -vcodec ffv1 -level 3 -coder 1 <outfile>
Yes.
q3 how can i see that my ffmpeg compile has ffv1 version 3 capability
Is it after https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/abe76b851c05eea8743f6c899cbe... <https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/abe76b851c05eea8743f6c899cbe5f7409b0f301> ? Or if you run `ffmpeg -h encoder=ffv1` do you see the -slicecrc option? Dave
