I don't know much about the intricate details of H.264, but: > The only differences I haven't been able to duplicate are the cabac > reframes, live capture have 2 while ffmpeg encoded have 4. If you think this could be the cause, you could add "-x264opts ref=1". But x264 should be getting its profiles and levels right by itself. > Also the audio codec of ffmpeg shows pcm_s24le (in24 / 0x34326E69) > while the capture shows pcm_s24le (lpcm / 0x6D63706C). As you mention, that doesn't seem to be an issue, but I think that can be manipulated with "-tag:a lpcm". > 3. root@pod2:/mnt/pod/drop# ffprobe > ../archive/_captures/services/2016/20160703_sunpm_richardmoore.mov You can dump the x264 encoding parameters using $ strings < file.mov | grep x264 You might also want to show us your conversion command line (which you did) and its complete, uncut console output (but I think that won't help much here).
