Quicktime 10 only exports audio, not video?

I'm trying to scale down a ProRes LT, 1920x1080 HD clip to H.264 480p. In Snow Leopard it wasn't a problem at all. I simply save as or exported using the built in 480p settings and Quicktime crunched it down nicely. But since upgrading to Lion, for some reason, Quicktime 10.1 will only export the audio only, not the video. I've scoured the discussions and web looking for an an answer but I can't come up with anything. I am NOT using the "Audio Only" optin in the export settings.


And yes, I know there's work arounds-Quicktime 7, Compressor, Quicktime Conversion in FCP-but why the heck am I doing that? I see that other people are having this problem, what gives?


Anybody got any ideas?

Quicktime-OTHER, Mac OS X (10.7.2), MacBook Pro, 2.66 Ghz, Core i7, 8GB

The posted problem involves exporting Apple ProRes video to H.264. Aren't these current Apple video formats?

Sorry! Was responding incorrectly to AVI codec issues. As previously noted, I could not duplicate this problem formerly under Lion nor currently under Mountain Lion. Am now wondering if this problem might be related to specific hardware platforms/components like the "Green Screen" issue.

Oh.


A quick wiki on Quicktime comes up with this:


"QuickTime is an extensible multimedia framework developed by Apple Inc.,"


Is this incorrect then? Also, as far as I understand things FCP wraps all its content in a Quicktime .mov file - at least that was the case with FCP7. FCPX may do somethinf diefferent - running with each file codec natively perhaps, but I am not sure about this.


As for not wastign Apple's time, I wouod not owrry too much about them. As far as I am aware Apple is one of the wealthiest companies in the world charging a lot of money for premium products. I am sure thay can afford to do a better job of keeping their customers happy and indeed I am sure they would appreciate the feedback.

Yes, it's a framework which is now, at least on a Mac, embedded in/has become an intregal part the operating system as a requirement for many QT-based GUI player-editing-compositing apps like QT X, QT 7/QT 7 Pro, GarageBand, iTunes, iMovie, FCP, as well as, many third-party apps like MPEG Streamclip. It is also the name of the generic file container used to wrap any compatible compression format for which a system is properly codec component configured.

If things have not changed, there are three basic software export options from within FCP:


a) To QT Movie—which exports the default import/editing/rendered compression formats directly to an MOV file type for quicly exporting referenced content.


b) Using QT Conversion—which allows the user to export to any available comression format in an MOV file container, and


c) Using Compressor—which allows the user to export to preset and custom compression formats in various file containers.

As was already pointed out, Apple does not regularly monitor the these peer-to-peer forums nor is this an officially sanctioned method of providing product feedback. As to Apple having money, time, and/or effort to waste on such indulgenies, I, for one, think it better to apply this money, time, and effort in actually fixing the problems already brought to their attention through formal channels rather than ignoring reported problems to monitor hundreds or thousands of daily forum postings looking for new/other/repeatedly unreported problems.
