Hello all

I was trying to extract a 5-minute segment of a video, keeping the same
settings using the following command

ffmpeg -ss 00:00:00 -i "input.mxf" -c copy -t 00:05:00 output.mxf

However the 'resolution' and 'scan type' of the output differs from the
original.

How do I retain the same settings in my output file? TIA.
