High definition video playback in Jitter


I’ve been trying to make a patch to display videos using Jitter, and I can’t get my video (which is normally HD in quicktime) to be HD in Jitter. I’ve put my patch below; what can I change to improve the video quality?

i didn’t test your patch but i guess you should define the resolution of the jit.qt.movie – or set it to @adapt 1, so it adapts to the incoming clip.

The @adapt 1 makes the whole screen turn grey instead of changing the clarity of the image… Any idea why that would have happened?

How about @dim 1920 1080?

you have to send “adapt 1″ before loading the movie. If you change attributes while the movie is playing you have to reload it.

Yoann, would you mind elaborating? I have re-loaded the video (with @adapt and now @dim as well), but it is still loading as a grey screen.

i have no idea what this grey business is all about.
can you post your patch, and maybe take a screenshot?

If you’re still using the patch from the first post, your problem is you have Use Source Rect enabled on the pwindow. Disable this (in the inspector) and with @adapt 1 on the movie object, all works great :)

Edit: ps If you’re going to be outputting to the pwindow, enabling Interpolation on it will also help with the quality a little bit more.
