I am making a game of sorts that uses audio and video and max/jitter are a good fit (live camera input, arduino enabled hardware triggers).

In the game sprites are drawn to a big jit.lcd that is sized 1920x1080 to match projector. There are also premade animations that I am rendering with jit.pwindows that are sitting right on top of the jit.lcd. When animations are not needed, I give the jit.pwindow a size 0 0 and draw black into it, so essentially the minimize. My CPU spikes to 90% when I play 3 movies in separte jit.pwindows that are sitting right on top of the jit.lcd.

I tried converting the premade animation videos into photojpeg and adding @unique 1 to jit.qt.movies that play them. Only one qmetro is driving all animations. Could you help me figure out a better way to achieve this and lower CPU usage? Should I output the videos as frames and punch them into the jit.lcd without rendering them in jit.pwindows on top?

Just to clarify, the jit.lcd is also piping to a jit.pwindow, the massive one under everything.

you should use opengl for this. below is a basic patch to get you started that shows how to use jit.world with jit.gl.videoplane to display and jit.anim.drive to animate your sprites. the input to jit.gl.videoplane can be an fpic object, a jit.matrix (or any object that outputs matrices) or a jit.movie object.

You are a gentleman and a scholar. Fantastic idea! Super thanks for the patch.

I was sticking to Max 6 because the runtime is very fast and efficient for that version. However now I see the benefit of jit.world in Max 7, and overall using it makes Max 7 run very efficiently. I will convert over to this method and think it is going to go swimmingly. Thanks again!
