Todd,

Yes,I have been batch renaming the file extensions and all is well.

Curious, is this a QT problem/limitation or is it something that fixable with a patch for Premiere?

Thanks for the attention to this subject…

This is something that we can fix on our side. It won’t happen immediately, though, since the fix is something that requires a lot of retesting.

The problem resides in Premiere Pro being too picky about what MPEG data it will try to decode natively.

Here is an anthropomorphized example of what’s happening:

Premiere Pro looks at the .mov file, examines its innards and says “That MPEG data is badly formed and not of the sort that I can handle. Hey, QuickTime, you try.” So QuickTime tries, and it can decode the data just fine—except that QuickTime is a terribly slow component operating across a 32-bit bridge.

But, if you rename the file, you’re tricking Premiere Pro by hiding from it the fact that it has QuickTime to fall back to. So it tries to decode the data because it has no choice. And—lo and behold!—it can decode the data just fine.

Got it. Thanks, at least the temp fix is easy…

Todd, Thankyou for explaining the “processing” behind the issue. These analogies and responses are a god send for FCP switchers and Longer term PPro users. It makes such a difference to hear that Adobe are listening and working. The tone of conversation becomes constructive and patient. Exactly what the Pro Video world is seeking and deserves.
Sincerely,
Jon Barrie

It is great that there is communication on issues like this. But it is a problem that needs a solution and not a workaround. There are programs I use that don’t understand the mpg extension and want to change them back to mov’s. I’m pretty sure they are being recompressed. At minimum they have to be renamed to mov, which could be pretty confusing. All I can say is please keep it a patch, not part of a 6.0 paid upgrade. Native D7000 playback was a big selling point here. Thanks for your attention, Adobe. It is appreciated.
