If only puredata just used YUV by default internally for _everything_ so at least it would be a bit faster, and I think a lot more work can be done to get a better video performance. Maybe someone on the list has a nice list of semi-universal tips to make video patches run faster?

GEM on OSX and pdp on any platform do this.

Or maybe for video puredata is just 'almost' fast enough with computers nowadays.. Can't imagine ever playing with GEM and pix_ stuff on a Pentium 3 for example. What I mean is, that puredata only recently has become a viable option for the stuff that you and I want to do with it?

I started doing 1920x1080 HD work using GEM on OSX in 2006 and never had performance problems. I had the engineers who write Final Cut Pro tell me that what I was doing was physically impossible with modern CPUs, yet it was done. At this point streaming raw video out of a 5D or P2 cam, recording it to disk while manipulating the video using shaders is the baseline for performance, not fantasy.
