[Andrew Rendell] "Depends on what the final use will be. Dropping frames will get you a technical fail every time at a UK broadcaster - it has to be motion predictive to get through over here. "
What i mean is that going NTSC to PAL, beside the geometry change, in the end is all about discharging information.
No in-between frames need to be generated.
No point to reprocess the whole movie, pixel by pixel (Compressor OpticFlow), for this purpose.
Out of compressor the movie may look choppy, but not muddied.
Standard or not in the UK, to get something better you'll need a Teranex or an Snell&Willcox.
When going PAL to NTSC, yes I would consider Motion Prediction, but not Compressor OpticFlow.
No Movement detection/Mask control. No way to avoid interpolation when no needed.
Again, reprocessing the whole movie just to create few in-between frames (that might have no much movement) IMO is not much worth.
Some times works better a humble frame blending.
