Is there an easy way to de-interlace a 50i M2T file the same way that Sony Vegas does it with the Interpolate settings? This gives the best results when I've been testing but I would really prefer to do this on my Mac instead of the bootcamp partition.

I have iMovie 08 & HD, Final Cut Express 4 and the usual tools like MPegSteamClip and JES.

Thx!

In MpegStreamclip you can export as a progressive movie. You should be able to export as a progressive movie from those other apps - though I don't use those so can't tell you the settings.
