I am able to convert the 23.98 source to 29.97, and the encoded file *is* technically interlaced, but the actual frame-rate conversion to 29.97 seems to be happening using progressive pulldown (i.e. repeated full frames), even though the file itself is flagged as having UFF interlacing. > > Because the 29.97 files are intended for broadcast playback, I need to be able to convert the 23.98 master QuickTime files to broadcast-spec'ed, interlaced 29.97 ProRes files with true interlaced 3:2 pulldown, so that they look smooth when played on-air.
Perhaps telecine filter is what you need? > > Here's the command line that I've come up with so far. > > ffmpeg -ss 7.0 -t 30.0 -i SOURCFILE.mov -timecode 01:00:00:00 -acodec pcm_s16le -vcodec prores_ks -vprofile hq -flags +ildct -r 29.97 -movflags +write_colr -color_primaries bt709 -color_trc bt709 -colorspace bt709 OUTFILE.mov > > This command line skips the 7 second slate/leader at the head of the spot, and encodes exactly 30 seconds of the file after that, while re-striping the output file with a new timecode track starting at 1 hour. I'm also using the Kostya ProRes encoder, as I have been led to believe that the other ProRes encoders in FFmpeg don't support interlaced output? > > Everything seems to encode as I'd like it to, with the exception of the lack of interlaced pulldown. I've spent all day scouring the web, as well as a dump of "ffmpeg -h full", but I can't seem to figure out how to get this to work. Any help would be most appreciated. > > > _______________________________________________ > ffmpeg-user mailing list > [email protected] > http://ffmpeg.org/mailman/listinfo/ffmpeg-user _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
