I’m suffering from the same maddening problem. I’ve recently got up to AE CS3 and up until a few weeks ago everything was fine but since last week I’ve been unable to import ‘.movs’ being confronted with the similar
After Effects error: file ‘FILE_NAME.mov’ cannot be imported — files of type ‘.mov’ are not supported.
(note there’s no error code)
ARGH!
I’ve re-installed After Effects and also Quicktime (with Quicktime Pro) and nothing has changed. I’ve opened the same project and imported the same ‘.mov’ on another computer and it works fine.
I’ve briefly read the link that Dave La Ronde supplied and although really useful doesn’t help immediately although I’ll go back and properly disect it once I’ve got a coffee…
Anyone else suffering from this?
Thanks
Jim
