which will be the most efficient way to low quality preview a 720x480 jpeg .mov

i tried first with jit.qt.movie changing its dimensions to 320x240

using jit.pwindow deselecting onscreen mode

however is still too much consuming (changing dimensions doesn´t seems to affect performance), the only performance relevant seems to be the jit.qt.movie metro banging frequency (which i´m being very permissive)

i guess i could use jit.window for hardw acceleration however i couldn´t find a way to crop the movie or to lower the quality (enough for able to show an small 320 x 240 or even smaller preview without too much consuming)

best way is to make sure that you follow some basic performance best practices for jitter: 

then, use @shared_context. On your shared context, bang the renderer more slowly, and then draw the texture of your movie on to a video plane in your shared context. This way you don't duplicate resources, and keep everything on the GPU.

Ill leave the patch for you to figure out

Vade. Don't want to take advantage of you. But I've tried (Just a week since I started with Max for Live ) and I can't this working. I mean sharing the context and draw the texture into a pwindow. Any additional detail will be very welcome.

post a stripped down version of your patch showing your attempt to get shared contexts working.

Man! Those recipes are ... what I needed. I'll try the 39
