Hi everyone, I got this strange problem with Quicktime -> H.264 codec in After Effect CC on Windows 7 64 bit.
The problem is that I can’t create mov that is in 1920×1080. After about 30 frames rendered the AE crash with information like “Can’t access the file”. It’s also after clean Windows 7 install. If the output is smaller like 1280×720 everything is OK.
I think thats might be something with files privileges, I have been rendering to different locations but didn’t help.
Did You have similar troubles? Any ideas?
Thanks in advance!
Try to install QuickTime Pro, it could be that !?
But i’m not sure, it could be an hardware problem too,
as not enough memory (RAM)
Try to empty your cache memory…and your computer temp
Thanks sfxstudio, unfortunately it won’t help.
It works fine with free Quicktime on my old machine that has 16GB of RAM.
The problem is with my new machines that has 24GB on first and 64GB on second machine, and as I said this happens even on clean Windows and AE install.
ps. It also doesn’t work through Media Encoder.
That’s why i tell you to try the pro version of QuickTime….. It’s maybe that cause there some differences with codecs… That could explain… Once again it’s a probability…. Try if you can Best regards Steve
Apple’s H.264 encoder has a severe bug that causes crashes in the encoder when 24 or more threads are used. So, people with computers with a large number of CPUs will hit this bug.
This is one of the many reasons to not use Apple’s H.264 codec.

Thanks, maybe this is the reason. I checked it on Macs but it was fine, so this bug is only in Windows.
No, the problem is on Mac OS, too, if you have enough threads going.
