A question: Where did you get actual 24 fps content? PAL is 25 fps, so if you convert to 24 fps, then why not just convert to 23.976 fps? IVTC'd NTSC is 23.976.

Anyway, you can always just:

Code:

ChangeFPS(59.94)
SeparateFields()
SelectEvery(4,0,3)
Weave() # or not

If your input is a progressive 24 fps, then ChangeFPS(59.94) will replicate frames to give you a progressive sequence that does a frame-based 3:2 pulldown (that's what 720p HDTV does), with the rounding when necessary. If the input is a progressive 23.976 fps, then ChangeFPS(59.94) will give you a pure frame-based 3:2 pulldown. In either case, you just pick off one field from each frame and voila!
