Codec AVOption gop_timecode (MPEG GOP Timecode in hh:mm:ss[:;.]ff format) specified for output file #0 (test45.mxf) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
File 'test45.mxf' already exists. Overwrite ? [y/N] y
Output #0, mxf, to 'test45.mxf':
