Export to a movie



Hi,
I export my OpenGL animation reusing some sample code I have found at the
Apple web site, like "CocoaCreateMovie" and "CompressMovie".
But, no matter which codec I use, which size, fps, data rate, compression
quality... any time I play the movie with QT, sometimes, *randomly*, my
movies skips some frames or more likely blocks for a little while.
I am getting crazy with that, because I looked at the code hundres of times,
but I cannot find the origin of the problem. Other movies I downloaded from
Apple trailers web site work flawlessy, so my QTPlayer is ok. My movie
frames are all there because the trouble happens time-randomly.

Could someone point me to the right direction?

Just to make an example, my last exported movie is a Sorenson Video 3, 512 x
320, Millions. FPS 30, Data Size: 14 MB, Data Rate: 575.9 bytes/sec,
Duration: 25 secs.


Best Regards
