Probably bought this on myself through a desire to saturate the viewer with video and audio! BUT if i run 3 max patches, 2 HD videos, 1 SD video, 5 samples and Module 8 together for some reason my MacBook Pro cannot handle the strain on its CPU......odd that :D Oh yer, i missed out constant serial communication....
OK, so the main issue is the HD heartbeat video. Standard playback is fine but I've found that continually changing the playback rate causes saturation of my laptops memory. This causes the video to jitter.
Luckily the problem has actually prompted me to think about how i am going to present the 3 different videos in my piece. The heartbeat video, the countdown video, and the live webcam feed. Ideally i need to present each video on a different screen and run in fullscreen (utilising presentation mode through the p-list editor on Max/MSP). I can only really do this by using either 2 external screens on one laptop (where i only have 1 video out so would require a splitter) or use 3 separate machines.
The latter is the solution i have gone for taking account of the performance issues. To solve, i found a way to send Max/MSP messages over a wireless LAN to control each videos playback from a master computer. Once i set up a new network using my Macbook as a host it worked perfectly within minimal lag-time.
