which way to improve the use of jit.qt.movie ?

Hi list !

My files are 1366 X 768 and my old(hum!) PowerBook labors.

I noticed to uncheck the “use onscreen” mode in jit.pwindow and ask me if there are others ticks to improve the fluidity of scrolling with jit.qt.movie ? ( except buy a MacPro :-) )

I thought about remake my jitter patch in JS, would it be less glutton in CPU use ?

I also tryed gem lib, but features are not the same .

tthanksssss

Derrick.

My graphic card is a ATI Mobility Radeon 9600 (Vram 64 Mo)
Not very nervous isn’t it ?

I haven’t ever used a Radeon 9600 but it is right on the edge of
having good texture and shader support. You can eek out performance
from reading large movies by choosing a proper codec that reduces the
amount of calculation needed to decompress a frame of video. MJPEG
Good quality is a popular choice. You can also use uyuv mode to halve
your bandwidth and display it on a videoplane with a uyvy texture.

there was a thread about opengl panorama scrolling way back. search for it.
codec is very importent, if you need alpha in your movie, try the animation
one, its heavy on the disk but takes less CPU to decompress. photojpeg is
another variant of the mjpeg family which i use.
if all else fails, try halving your movie size and up sample it in jitter.
slight stuttering with moving videoplanes is a pain, especially with high
res movies. i know how you feel.
