== Description ==
[[IVTC_txt60mc|ivtc_txt60mc]] deinterlaces 60i credits on the top of a 24 fps telecined footage. It virtually oversamples the video to 120 fps with motion interpolation on credits only, and decimates to 24 fps. It has the advantage of avoiding footage frames interpolation, leaving them very clean, whatever the motion they contain. However, the drawback is that it requires to manually measure the origin of the 3:2 pulldown pattern (and split the clip in parts if it changes).

== Requirements ==
* [x86] [[AviSynth+]] or [http://sourceforge.net/projects/avisynth2/ AviSynth 2.60]
