Hi Hardik,

We usually ask you to provide the full (real) command line and the
complete, uncut console output. There is a lot of valuable information
in there.

"-c[:x] copy" tells ffmpeg to copy the corresponding stream without
modifying its contents or encoding. When creating interlaced content
from progressive content, you will have to change the contents of
fields and frames, if I'm not totally stupid. That means you need to
re-encode, and that means you need to drop "-c copy".
