If i want to transcode a file from progressiv to interlaced,
the timecode will not be be the same.
It doubles the last frame.
Example:
Original File 10:20:15:7
After transcode 10:20:15:14
{{{
ffmpeg -i "%%i" -vcodec dnxhd -b:v 120M -q 1 -flags +ildct -vf
"fps=50,format=yuv422p,scale=1920:1080,interlace,fieldorder=tff"
-map_metadata 0:s:2 "coded\%%~ni_1080i50.mov"
}}}
many thanks
Tim
