Improving performance by using GL > jit.qt.movie & jit.rota

Hi.

Apologies if this is covered elsewhere. I am making a simple patch that takes two videos and outputs them as a single window to be made fullscreen. The window will be split vertically down the middle and show one of the videos on each side. Each video will pan across from left to right over time. Below is what I have so far. This works exactly how I want it to so far except that as soon as I import one of my videos (time lapse photography, 2minutes long about 300mb) instead of the example crashtest.mov it becomes too slow and crashes. I want to use gl objects to utilise my gfx card's processing power but I'm unsure of what gl objects will get the same results?

Thanks
