[FFmpeg-user] Issues with converting DNxHD MOV to IMX50 MXF D10

[Robert Nagy]

I have an DNxHD file in a mov container with a timecode track I want to
convert into IMX50 mxf D10.

I'm having some issues with copying over the timecode track from the source
file, I get a " track 2: could not find essence container ul, codec not
currently supported in container" error.

Also, when encoding the video I keep getting "rc buffer underflow max
bitrate possibly too small or try trellis with large lmax or increase qmax".

What am I doing wrong?
