When you guys do an x264 HD encode of a 60 fps 720p stream, are you typically leaving the framerate alone or do you invoke some inverse telecine plugin in your .avs?

OK, so you are reducing the 60 fps to 30. Others?

Regular scripted televison shows? TDecimate(CycleR=3) ... works on 90% of the shows, some have some weird cadences and require a lot of hair pulling and the results are not always the greatest. Have you got a particular show in mind? ABC shows(LOST in particular) are notorious for playing around with dropping intermittent frames here and there.

23.976 not 29.97

Does that work better than TDecimate(CycleR=3)?

I know TDecimate(CycleR=3) is very fast and uses hardly any CPU. Does the method you described help compensate(smooth out the playback) for the strange cadences inherent in a lot of the ABC shows?
