I'm playing two videos separately using jit.qt.movie, both at a resolution of 640x480, and mixing them together using jit.xfade. But when I'm playing them both together I'm getting very poor fps numbers and the videos become jittery. The fps value stays around 8 or 9. The output of the xfade is going into jit.pwindow again at 640x480.

My computer is a 1.83 Macbook Pro with 2GB of ram so I can't imagine that its a problem with my computer.

Is there a good way to get the numbers back up? Or is it that my resolution is too high?

Also, even though the resolution is at 640x480, one of the movies that I'm playing (which was originally 848x448) is very pixelated.

I'm new to Jitter so sorry if I'm just being daft!

There are plenty of posts about getting frame rates down, including

removing ui objects and optimizing the video you are using. On your

specific case, it would help if you posted a patch and let us know how

things about the video (how it's encoded, fps, etc). Hope that gives
