Are other export formats available working correctly for these same v210s
or is it just ffv1/mkv that you’re seeing the issue with?


Every time I try I get the following error:

Can you post the complete terminal output including the actual command
used? Perhaps there’s other issues further up. I’m not able to figure this
out but it looks to me like there could be an issue with the command or the
input files? Weird that it works fine on an older Mac though.
