Don't know if you read "My poor iBook" thread but I touched on the topic of deinterlacing. Final Cut Express can deinterlace video, it is one of the built-in filters. Unfortunately iMovie cannot deinterlace AFAIK.

Simple. Use either FCP or FCE and apply the de-interlace filter under effects/video filters/video. It is a processor-intensive task and even small movies will take a long time to render. I remember someone posting about applying a de-interlace filter for a 40 minute movie and on an iBook it took 13+ hours while on a PowerMac dual 1.25G it still took 2+ hours. De-interlace filter asks alot from your mac but results are very good.

there are free options too. ffmpeg has a decent deinterlacer. And if you have DV source you can export from QT Pro with the "single field" option checked in the "high quality" pane, but you'll lose half your resolution along with the interlacing artifacts

have a look at

http://www.joesfilters.com/


he's offering a deinterlacer, which is in many tests proofed much better than the one in FC(E).

there are also some "professional" solutions, which are only for FCpro and costs a hell of money and processor time.

easiest way. film in progessive/moive mode with your camera! it's done in realtime, no probs with artifacts and sigs........ problem here: camcorders supporting this mode are EXPANSIVE!!

Thanks for you info, people, but I don't use FCP or FCE. I use Combustion, AfterEffects, Cleaner, & QTPro. I know they all have deinterlace options, I was hoping to find a "how to" or tutorials on deinterlacing.
