Hi everyone
I've a big problem with aftereffects CS4 and quicktime 7.6 working on vista 32 bit.
I can't open .mov files, aftereffects crash wehn i try to import a file with that format. I read the other topics but nothing worked. Is there a solution.


I've a dual core processor 2.20 GHz with 2GB of ram

There are several things that could be going on, and you don't give enough information to make a good guess.

[Alem Mascol] "I can't open .mov files, aftereffects crash wehn i try to import a file with that format."

The mov. file suffix only indicates that the file is a quicktime move, which is simply a container for media. It tells you NOTHING about the CODEC used to encode these files. This information is found at the top of the project window when you highlight the movie. Knowing that, you should read this:

Dave's Stock Answer #1:

If the footage you imported into AE is any kind of the following -- footage in an HDV acquisition codec, MPEG1, MPEG2, AVCHD, mp4, mts, m2t, H.261 or H.264 -- you need to convert it to a different codec.

These kinds of footage use temporal, or interframe compression. They have keyframes at regular intervals, containing complete frame information. However, the frames in between do NOT have complete information. Interframe codecs toss out duplicated information.

In order to maintain peak rendering efficiency, AE needs complete information for each and every frame. But because these kinds of footage contain only partial information, AE freaks out, resulting in a wide variety of problems.




[Alem Mascol] "I've a big problem with aftereffects CS4 and quicktime 7.6 working on vista 32 bit. "

Do you have the free upgrade to AE 9.0.2? You should get it.




[Alem Mascol] "I've a dual core processor 2.20 GHz with 2GB of ram"

With only 2GB RAM, you should NEVER try to use AE's multiprocessing feature. You don't have enough RAM.

Two other things: don't render using Open GL acceleration. It doesn't work properly. If your disk drives are formatted as FAT 32, you need to reformat them. FAT 32 has a 4GB file size limit, and media files can easily be larger than that.

Thank you! That son of made my mov files don't work. Now mov files are no more a problem. Thanks.
