Summary of the bug:
How to reproduce:
{{{
% ffmpeg.exe -y -r 59.94 -i SRC.mov -acodec copy -c:v libx265 -crf 28 -vf
"transpose=1" -r 29.97 DST.mov
ffmpeg version: N-89955-g118e1b0b33
}}}
Timecode when transcoding from 59.94 --> 29.97 timecode is not being
calculated correctly resulting in incorrect start and end timecodes.
Tested on multiple input and output codecs including prores, h264, h265
Start timecode on 59.97 is 09:31:58:30.
Start timecode on 29.97 is 09:31:59:00.
It should be 09:31:58:15
