Both of these examples get the frame out of QuickTime before passing the image to QuartzComposer. Can you write the image to disk to see if the image is OK before it gets passed to QuartzComposer?

Regardless, if there is a bug, please file it.

hello

this is a problem that is similar to a November post that did not seem to get resolved on this board.

When you pass frames from a movie encoded with some specific codec (I've tested Sorenson so far) to a composition, it fails to render them on Leopard.

You can try the following Apple sample code, MovieFX, with a Sorenson encoded file. It fails. It works fine with other movies (H264). On the other hand, QuartzComposerMatrix works fine with the Sorenson movie.

Does anyone from the QCTeam have a clue ?
