[FFmpeg-user] V210 to MKV transcoding issue

[Kieran O Leary]

Hi Leila,

I used an Apple Silicon Macbook using FFmpeg 7.1.1 from homebrew just
there to process a v210 with similar specs using your command and
couldn't replicate the issue. I'd be curious to know if you got the
error with any other format, for example with a a basic h264 command
like:

ffmpeg -i /Volumes/Preservationworking/Work/Preservation\ \(FFV1\,\
mkv\)\ \(96kHz\,\ 24-bit\)/UA-F003035_pres.mov -c:v libx264 -crf 21
-pix_fmt yuv420p /Volumes/Preservationworking/Work/Preservation\
\(FFV1\,\ mkv\)\ \(96kHz\,\ 24-bit\)/UA-F003035_pres.mp4

Your decoding looks like it didn't trigger any errors and it got past
frame 41, unlike your FFV1/MKV command.
When running the command on the other mac where you get a successful
outcome, is this connected to the same storage device? I don't see any
of the usual errors that I would expect to see if there was corruption
in the source file or there was some sort of error on an FFv1/MKV
level. Is there any chance that this could be to do with the
connection to the connected Volume on that Mac?
Are you able to run this command on local or external storage on the
same mac with the same input file to see if it gets past frame 41 at
the very least (i imagine you may not have the disk space to process
the whole file, but your output died in the first two seconds.

Best,
