Thanks to the help of jagabo (https://forum.videohelp.com/threads/317299-IVTC-a-vob-m2v-file-before-FCP-editing) i'm learning quite a few things about pulldown flags IVTC etc

Ive seen a few posts on similar subjects and it seems as though Avisynth can IVTC a video file with many pattern breaks and mixed telecined/progressive material reasonably well.

Is there a program on a Mac that can do this just as well? Obviously free is preferred as I just went out and got FCP recently!
