jit.qt.movie – low frame rate

Hello All.

I’m trying to play 3 H264-encoded movies simultaneously using three jit.qt.movie objects. Eventually, I’d like them to play on three separate monitors.

However, I’m getting very low frame rates (between 8 and 12) and eventually it drops to 5 fps. When I play the three movies at the same time in Quicktime Player, I get the full 25 fps.

How can I increase fps in Max? Is jitter inherently CPU intensive?

Jonathan.

search for “optimization” on the forum. vade’s and tyler’s threads are very
recommended.
