and yeah, this French-language pdf actually says the same:<br>

so, I looked up ffmpeg cmd line<br>
<a href="https://trac.ffmpeg.org/ticket/3597" rel="noreferrer noreferrer noreferrer" target="_blank">https://trac.ffmpeg.org/ticket/3597</a><br>
<br>
ffmpeg -v info -i /mnt-data/backup4/vol0/export/CUHK\ 2014-1/V017b.mov <br>

Huh, said I and entered those params in opts file, actually in two files (mp4 and mov containers)<br>
<br>

<br>
both for progressive content, for interlace you must add some more flags:<br>
<a href="https://lists.ffmpeg.org/pipermail/ffmpeg-user/2017-January/035049.html" rel="noreferrer noreferrer noreferrer" target="_blank">https://lists.ffmpeg.org/pipermail/ffmpeg-user/2017-January/035049.html</a><br>
<br>
-flags +ildct+ilme<br>
-x264opts interlaced=1<br>
<br>
Also, there is still lack of (GUI) user notification if file writing failed due to <br>
NO SPACE on device :}<br>
<br>
FFStream::write_packet: write packet failed.<br>

Profile sort of assumes you set project to some supported resolution, framerate, etc,<br>
otherwise libx264 will fail with console error message.....<br>
<br>
I found some talk about AVC-Ultra, there even was patch for x264, but it was not merged:<br>

<br>
<br>
Also, I think sound must be uncompressed, but I'm not sure.<br>
