ffmpeg shows an ugly warning when using the -timecode option since d64b8540 (the option apparently works fine).

Codec AVOption gop_timecode (MPEG GOP Timecode in hh:mm:ss[:;.]ff format) specified for output file #0 (out.mov) 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.
Output #0, mov, to 'out.mov':

error: short SHA1 d64b854 is ambiguous
