I'm trying to read HD video in 1920 × 1080 (codec H.264, size 160 mo, type Vidéo MPEG-4) using jit.gl.videoplane, but the framerate is very slow (as Max 7) : 4/5 FPS. When I read the same HD video in 1920x1080 (codec Photo - JPEG, Timecode, size 175mo, type Quicktime), no problem : 25/30 FPS.

I tried with jit.qt.movie, same result. I have this problem with all my MPEG-4 video. Does that mean MPEG-4 videos are bad for jitter processing ?

I used the first video on this link to make my test :

I also wonder if it's possible to make the same kind of abstract visuals with jitter and Open GL : block of color slightly blurred, smoke, liquid, etc.

And also @engine avf (default) enables you to run Max in 64 bit mode :-) 

Run everything on gpu.

Thank you for the help Phiol ! It's exactly what I wanted ! I understand how the patch work, except one thing : tranform_reset 2 for the videoplane object.

Makes it adapt to full screen for jit.window.

exactly what andro said :-)
makes your videoplane fullscreen.

the term transform in 3D world means
position
scale
rotatexyz
parameters 

Thanks for both answers. I understand now.

In jitter world, it's often really difficult to understand message effects, even with max help and reference...

yep I totally agree that the documentation is really way too cryptic especially with gen that's been out since 2012. still no helpfill for gen objects.

really added some steapness to the learning curve..

Also, a big of confusion for new comers is rhe difference between regular jit.blabla and gl jit.gl.blabla objects.

anyways , I once wrote a more detailed explanation

no prob !

still does.

here I'll try to find it and make a wiki
