I am working on a project to create an interactive theatrical production and I, with a lot of help from the forums, have completed the basic patch I need.

However, I am currently doing a mini-stress test of the system with placeholder videos (roughly 30 total) take up around 13 GB of space combined. I believe I will need to include much higher resolution videos that will possibly double this size very soon.

I have already experienced some possible performance issues with the path: video freeze, audio and video out of synch.

I was wondering if there was anyway I could optimize the jitter patch to make sure it is using the system memory as efficiently as possible.

I have tried sending a loadram message to jit.qt.movies and I think it helped but I dont know why. However, I dont really know how to To buffer decompressed matrix data to RAM, using the jit.matrixset object...or if I even want to do that.

I have also read about offloading a video to a slab, using preroll messages, or asynchread. However I had trouble implementing these techniques and I think I am already pre-loading my videos and audio files at the beginning of the patch anyway...

I would appreciate any advice or help in this matter greatly. The forums have already been an amazing resource.

optimizing-jitter-performance-for-large-number-of-videos

Well for starters have all ur videos on a seperate hard drive from the one running ur apps, works for me.

As for all the complicated stuff, cant help u their. Keep trying and ur get there.
