[FFmpeg-user] A change in -timecode ?

[Bob Maple]

Updated to a more recent Windows build of ffmpeg and have been getting
something new when using the -timecode switch making Quicktimes:

  Codec AVOption gop_timecode (MPEG GOP Timecode in hh:mm:ss[:;.]ff
  format) specified for output file #0 (D:\13HD2002H_ProRes.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.

but I'm sort of not deciphering the meaning, and further confused by the
fact that it all seems to work anyway -- I get the desired timecode in
my output movie as before.

Is there some other method I should be using, and/or what is this
warning (?) really trying to tell me?


Complete console:

ffmpeg.exe -i "D:\13HD2000H.mov" -timecode 01:00:00:00 -top 1 -flags
+ildct -codec:v prores_ks -profile:v hq -pix_fmt yuv422p10le -vf
