Being a rookie with no film or video schooling, I am doing everything on my own, with a little help from you guys or some random kind soul I come across...anyway, a couple of days ago I was doing my homework:
-I filmed myself in all shooting modes (DV, HDV, HDV24P, on Cine, Tv, P, Av..)
I loaded evreything up on my computer, watched each one of them, then I chose one, say: HDV24p/Tv(60) and using iMovieHD6 (I still can't get the Final Cut to work) I compressed every different option, like: Apple Codec, QuickTime, Sorensen. And at different sizes, checking and unchecking the "deinterlace' box... And they are all signficantly or mildly different, however, ALL of them display those awfull horizontal lines after being compressed, they look like noise, or horizontal ghost lines...What is going on, how can I avoid it?
PS> that also happened with non 24p, and on the DV, it has weird VERTICAL lines! Whata?
Thank you in advance, Titi.:eek:

I'm having the same problem with iMovie 6 and my HV20 video captured at 1080i. I posted about it on the Apple Forums (http://discussions.apple.com/thread.jspa?threadID=1302514&stqc=true) with no replies.

The crazy thing is that when I compress to 720x480 iMovie does deinterlace. It always looks deinterlaced in the editing preview regardless of export settings. I do have "deinterlace source video" checked in the "size" options.

Voix,
I tried all codecs (or nearly all, and I made notations of each and how they looked and performed, and all of them had them lines). As it turns out, acording to some people here on the forum it may be only an issue of display, once the video is displayed in a tv or projector, the lines should disappear. I do not have a TV or projector so I haven't tried that yet, but if you haven't, give it a shot and let me know. Good luck.:hv20-smilie01:

Well, I have my Mac Mini hooked up to a 1280p projector. That's where I view/capture/edit my HV20 material. It's definitely interlaced.

After reading the forum I learned of JES Deinterlacer and gave that a go. It worked, and I may just have to add that as a step from now on.

Seems to me that iMovie 6 is bugged.
