Quicktime movie is shown on screen when using QTMovie addImage:



Hello,

I am building an empty movie as in the QTKitCreateMovie example, and adding images to it using the addImage QTKit method. The problem is that the frames are shown on the screen, aligned to the upper left corner while the movie is created. The last frame remains in screen, unless a window is moved over it, and then the desktop refreshes.

I've tried to use the following code to move the Movie offscreen, but it doesn't work:

GWorldPtr offscreenGWorld;
Rect rect = {0, 0, 1, 1};
NewGWorld(&offscreenGWorld, 32, &rect, NULL, NULL, 0);
SetMovieGWorld(qtMovie, offscreenGWorld, NULL);	

I am calling this code immediately after I call CreateMovieStorage to generate an empty QuicktimeMovie.

How can I make the movie being worked on go offscreen?

Thanks,
Juan
