Hey guys, so apparently, my unboxing of my iMac 21.5" (yes, I'm the geeky) seems to be interlaced. The source video AND the exported video is interlaced. So to give some background on my situation, I previously used my Acer Aspire 3680 with Free AVCHD Converter to convert all of my .mts files to .mp4 files. Everything worked fine and considering my laptop was too weak to do movie editing, I just uploaded the .mp4 video up to video with no special effects. At that time, I believe that I used 60i to film my videos. I use a Canon HG20 to film all of my videos. However, now that I've switched to the Mac, I have a much more powerful machine and I'm able to edit my YouTube videos onto iMovie (I plan to move onto FCE to get into actual amateur films later on in the next month or so), I've edited everything in iMovie '09. So the main problem is that when I finished editing everything, I exported everything using the "Export Using Quicktime" feature and once it finished, it had interlacing (not too pretty). Shocked, I looked it up and found a solution on Google and found that I should use the "deinterlace source footage" feature of iMovie. Great, but soon, after I found out, it still had the same effect. Turning back to Google, I tried another solution which was to export the regular way, using iMovie. Great, tried that (and it took 15 minutes compared to an hour to convert everything) and still, I have the SAME problem. This has become a large headache for me, and does anybody out there have a free plugin or links to any free software to deinterlace my video? Also, why am I having this problem on my Mac when I didn't have it on my PC? Just seems really weird. Do I have to upgrade to FCE to get the deinterlacing filter ? All help is appreciated. Thanks guys!
