AE CS3 PRO. Out put settings, quick time mov'format animation,depth,millions of colors plus.color premultiplied. Ok render is fine alpha chanel fine. Problem is when I try and import the same file back into AE. Crash!...The same file works ok in Prem pro and other apps,including quick time player?.....Any ideas!..

millions of colors plus you meant millions of colors+ right?
not
millions of colors. the later doesn't support alpha. AE is very picky. and if you try a different codec output, bets are AE will work again. The animation codec is very buggy if you try to output a complex project with it. Try a different lossless codec for a small render and see if that fixes it.

[Chris Wright]"The animation codec is very buggy if you try to output a complex project with it."
Holy Cow, that's news to me! The Animation codec's the closest thing I've found so far to the Gold Standard!
I've never, ever had problems using the Animation codec, not even on Windows boxes. Okay, I've made some Driver Error-type mistakes where I needed a Straight rather than a Premultipled Alpha channel, but that's IT. I've made lower-thirds, full-screeners combining full, partial and zero opacity, I've used combinations of various Animation-codec clips in my NLE, and I've never had so much as a hiccup.
I'd be interested in knowing what kind of bugs you've experienced, and what you think caused them.

its not really the export as it is the corrupt interpretation AE gets when you try to import the rendered animation file back into AE. That's why you probably haven't seen it crash much. AE's render and import code don't always 100% match. ie.(crash).
Huh? An animation-codec file is an Animation-codec file. AE doesn't make 'em, AE uses Quicktime to make 'em. I probably should have mentioned that I have a library of home-made animations that I use to make life easier in AE: you know, animated mattes, graphic elements, various looping things. They've been built over the years, using various versions of AE, and they all use the Animation codec.
I'll take a guess and speculate that you're on a Windows box, and that it's possible you have a couple-three viruses to contend with, which could be making life in other applications a bit more difficult.

"AE's render and import code don't always 100% match. "
I made a lazy answer. I should have said, AE's dll files still have to interpret the quicktime codecs and if the quicktime files are corrupted, AE will fail to open them, but other players still might because they're not as sensitive to errors.
it might be interesting to ask the first poster, marti davies, if he's using pc instead of mac. It could very well be that macs with animation codec are more stable than pc's. I'm not a programmer but I can say this, would it be in the better interest of Apple to make a more stable quicktime for Mac instead of PC? lol.
