This shouldn't be needed: if your movie is a 10FPS movie for
instance, the movie patch will only refresh internally at 10FPS
and compute / produce a new image when necessary.
I think I did not explain my situation properly.
My Movie is a 30fps movie BUT I would accept it to play "slowly" if
the computer is too loaded.
But not the text scrolling. I want this one smooth. Always.
And yes that's right, it renders only the frames needed
Ddoes your performance problem goes away depending on the type of
you movie you use? If you just use the movie QCRenderer, is it
smooth?
Yes, it depends on the movie.
Actually I have my problem only when two HDs movies are playing at
the same time.
Therefore : no, with just the movie renderer, its not smooth.
But I would like the text scrolling to be smooth anyway... to give
it a higher priority in a way ...
Try using a custom timebase on the movie patch and pass a value that
does not increase continuously but in steps e.g. 0, 0.2, 0.4, 0.6,
0.8, 1.0 over one seconds will produce 5 frames instead of 30FPS
