Hello everyone,

i need advice on this. I have a material from a sports event. It's 50i. It was converted from ntsc ~60i). The "conversion" was done by final cut. In my clip i have 10 fields then there's a gap in the motion another 10 fields and so on. FCP seems to copy 10 fields then throw away a certain amount and so on. I try to find out the exact pattern by converting a burnt in timecode clip right now.
My idea was to interpolate the missing fields to get ~60i again and then do the ntsc->pal conversion the right way.
Whats is a good way to interpolate the missing fields?

EDIT: i found MVFlowInter (http://avisynth.org.ru/mvtools/mvtools.html#functions) looks promissing

regards
