I was just trying to see if this //could// be done, and I have failed. Bottom line is that QT simply does not support 64-bit, and the freeware "Quicktime Alternative" doesn't seem to talk to AE.

Has anyone else succeeded in getting Windows XP 64 bit (so you can run the system using greater than 2-3 gigs of RAM) running Adobe After Effects using Quicktime footage?

Navigate to the apple.com page to download quicktime using your 64-bit Internet Explorer.
Only then will you be able to download the 64-bit quicktime (it's still a 32-bit program, but it plays nice with 64-bit OS).
Hopefully this helps.

**Edit** Sorry I didn't read carefully, you are using XP64. I'm on Vista x64 so this action works for me. Give it a try though. Picture shows downloading the itunes+quicktime package. I suppose you could download the quicktime only package. But I can't seem to find it on the site...

I meant to try thiks over the weekend, and follow up with thanks. Never got to it, but I will.

And thanks for your reply, I had/have not tried that. I'm new to 64bit.

I use xp 64bit and QT works just fine - well, mostly. The only issue is that the actual play bar is black, but otherwise, I can play qt files no problem.
