Re: [FFmpeg-user] Size of 10-bit 4:2:2 video streams?
The only occurrence of "non-interleaved AVI" is on avidec.c:
if (avi->non_interleaved) {
av_log(s, AV_LOG_INFO, "non-interleaved AVI\n");
clean_index(s);
}
and from a quick read of clean_index(), all that's doing is building a new
index for a given stream. Absent other info, I'm not sure the message is
more than information.

Hard to guess.
You could inspect file in some AVI file format analyzer.
If there is such thing available.
In theory, avicodec will do it but it's quite old, same for vitrualdubmod
and gspot (http://www.headbands.com/gspot/), but then AVI format is also
quite old. I have used gspot before and it was useful, haven't tried it for
this purpose.
https://greshka.net/avicheck/ has some interesting suggestions, which
eventually land on "ffmpeg -v 5 -i FILE.avi -f null -" (decode to null
output, turn up the error reporting.
I'll echo Paul's thoughts that the AVI is somewhat corrupt, at least the
metadata is badly wrong. It's possible that by either poking the metadata to
"correctness" or ignoring a lot of errors, usable video could be pulled out.
Later,

Re: [FFmpeg-user] ffmpeg MP4/x264 output colours change when input source is different resolution (bug?)

Would you consider both of the lines safe to use? Unfortunately, the line that I used which failed before, now also succeeds in producing accurate colours: ffmpeg.exe -i testchart.png -crf 0 -vcodec libx264 -t 5 -y -colorspace bt470bg testchart.mp4 Here is the URL again for the test chart: https://www.belle-nuit.com/test-chart I'm at a loss why it's suddenly producing correct colour results when it didn't before. If you insist on using these VUI options, then in contrast to what you might expect (PC,BT.709) it's actually TV,BT.601 that has the expected result. Welcome to the wonderful world of video conversions. Feels like I'm going crazy haha. Hope it's all simplified and unified in the future, and all this arbitrary legacy baggage can be put behind us once and for all.

The resulting MKV file has a duration of 38 minutes only and can be played without any problem. Actually, I think I can do pretty much anything with the problematic AVI file using ffmpeg. It will just see it as a normal 38-minute file. - Examine the file with ffprobe (ffprobe -hide_banner -select_streams v:0 -show_frames). The full output log is available at the same location as the mediainfo output. I get information for 58254 frames, so about 38 minutes of video.
