Do I assume a de-interlaced NTSC video comes out a de-interlacer at 60fps(Hz)? Using tomsmocomp deinterlacing (for AVIsynth) as a reference, I notice that that doesn't keep all 60 fields, as it only outputs 30fps so it's combining each pair, not interpolating between the full 60. I asume Dscaler's tomsmocomp does the same, hence I assume this is why people find de-interlaced PAL at 75Hz fine to look at. My question is; - What output rate do most de-interlacer/scalers produce, say for an NTSC input? Also, - What happens to the output rate when 3-2 pulldown detection kicks in and then only 23.976fps are available? thanks and regards, Rob.
