thanks, other problem that i have with the ffmpeg prores is the duration, if i open with quicktime/davinci resolve the duration is 2 seconds, the solution is with ffmpeg -c copy and then the duration is ok, ffmpeg said that the container need global header and the file not have global header. thanks
