[FFmpeg-user] IVTC with pullup filter

[Elliott Balsley]

I have a source video that's 29.97 with 3:2 pulldown, and I want to encode it at 23.98p.  This ffmpeg command produces video at 23.98, but with a pattern of 2 progressive frames followed by 2 interlaced frames.

ffmpeg -ss 208 -i NCIS.ts -t 30 -vf "pullup,fps=24000/1001" -acodec copy -vcodec libx264 pullup.mkv

On the other hand, I can achieve perfect results with this simple AviSynth script:

MPEG2Source("NCIS.d2v", cpu=0)
TFM().TDecimate()
Trim(5000,5300)

Since AviSynth isn't doing any deinterlacing, I don't think I should need to add yadif in ffmpeg.  How can I make the pullup filter work correctly?
