Does somebody else has this problem?
Yup: I heard about it just today, in fact. An FCP user was trying to get Cinema Tools to conform 24fps footage from a Mk II and Mk III to 25. No problems with the Mk II footage, but no luck with the Mk III footage.
Now, it could be just coincidence. But if you don't believe in coincidence, you might think that there's something screwy with Canon's new codecs for the Mk III. "Screwy" is a highly technical term, by the way.
Yay!!! Just did something real stupid out of curiosity and it works now!
I've renamed the footage from *.mov to *.mp4 and now I can import it in After Effects & Premiere CS6 without problems. And it plays so smooth.
Seems like something is mixed up with Quicktime.
You could be right about Quicktime. I forgot about that.
Here's a question that could tell the tale: are you running QT7 (good) or QTX (bad)?
It's the standard Quicktime 10.0 (131) that was delivered with the mac system. Why should I put the old 7 on it? Aren't there any compatibility issues with older quicktime versions?
QTX is most charitably called "a work in progress". There are those who call it other things.
You'll find QT 7 as an optional installation on your OS disks. You should take that option. If you're reluctant to delete the QTX application file, you can always rename it so the OS doesn't see it.
will check my Snow Leopard CD because on the apple support site there is no Quicktime 7 for Snow Leopard. Only for Leopard and Tiger.
Okay found Quicktime 7.6.6 for SnowLeopard and installed it. Now I have Quicktime 7 in the utilities folder but importing *.mov files from the 5D Mark III still crashes After Effects and Premiere CS6. Moving Quicktime 10 to the trash bin didn't helped either.
!!! Just to let you know - I've found the real problem !!!
I have the CineForm codec installed with the GoPro Studio Premium software.
After removing the file "CFHD_MOV_Importer.bundle" (I've put it temporarily on the desktop) I can now import the Canon 5D Mark III without problems.
The file is located in: \Library\Application Support\Adobe\Common\Plug-ins\CS6\MediaCore
