Hi, I'm working on a patch that plays a random video. I'm using pix_film because I need to cycle back and forth through frames using a sensor and an arduino like an old style penny arcade machine. My main problem is that the patch becomes very slow and stalls when I attempt to move back through the frames. I understand from other topics I've read that pix_film uses up a lot of ram so I'm just wondering is there a more efficient way to load the movies than I am using currently so it won't be as slow? They are all approx 1 min long. I've attached my patch below.

I would consider reformatting the video. By adding more keyframes, you reduce the amount of processing the computer needs to generate a retrograde point in the footage. To go one second back, if you only have a keyframe every 10 seconds the cpu needs to regenerate 9 seconds of video. Until RAM becomes a problem, less compression means faster [pix_film] response times.

Or, you might be able to achieve your desired affect with [pix_delay] and a clever xfader.

I don't know on what os you are but if you're not on windows you could try pdp instead of gem. I find it less cpu expensive.

Thanks! I'll give it a shot
