Example patches of recording OpenGL -> QuickTime

February 17, 2009 | 8:49 am

Hi all, I’m a newbie in search of example patches that illustrate how I can record QuickTime movies of video processed thru OpenGL effects and primitives using shader techniques.

So far my search has taken me thru jit.desktop (not optimal method), the FAQ (don’t know how to extract .sit file), and of course jit.qt.record. The jit.qt.record tutorials don’t really cover OpenGL-related concerns. Where I am currently at is that I believe my best approach is to capture jit.gl.render using a jit.matrix of same name. However when I attempt to do this the patch crashes the entire environment. I am using Max/MSP 4.6.2 and Jitter 1.6.2.

Would anyone have links to more indepth examples and tutorials covering this topic or any advice based on the description of my issue above? Many thanks in advance.

actually, since max 5 the best way to do this is with jit.gl.asyncread.

although if you’re only recording the movies, and not trying to do further matrix processing, i still prefer iShowU.

Thanks Fabrice! That’s exactly what I was looking for!

Great to be a part of this community – hope to be able to contribute soon as I get my mind around this environment.

Thanks for the response robtherich. I’ll have to look at the jit.gl.asyncread technique once I upgrade to Max 5.
