Andrew, I think use two input video examples<br>
1) SD-DV <br>
2) HDV <br>
<br>
Currently ffmpeg-7-7.0.2 on Tumbleweed-Slowroll (but
have also ffmpeg-7-7.1 on Leap if wanted)<br>
I use output.log file. For some reason the terminal
output alone is seemingly more verbose, and longer
than I can scroll back to copy.<br>
<br>
</blockquote>
Oh, the reason was the ffmpeg output file existed and it
wasn't overwritten.<br>
I also shows that the output is too long for Cingg
messages, and I try to post the two log files compressed
by email if acceptable(?)<br>

I posted them directly this time as .gz<br>
If you tell me what to 'grep' or search for I can extract it and
