I think Miker's got a point the slow frame count confuses the general style of you trailer.

I use Sorenson codec which I think gives the best results, your sound track only takes up 234k of the file, I recon it could be higher. You can half the file size and keep the same quality by checking the mono option as apposed to stereo like what you've done.

Audio I like using uLaw at 22hz

Generally think the movie is excellent, the only thing I'd say is its more of a seqence than a trailer.

I might add that the great thing about QuickTime is that it can be analysed by anyone, 'Apple' + 'i' key and 'Apple' + J (I asume PC users can also access this info although they dont have an apple key)
