How do you make a quicktime file from rendered gl?

Hello,
I’m hoping someone could help me with a dilemma I’m having. I’d like to use the “jit.qt.record” object in order to make a quick time file of some rendered material from a jitter example program (which I uploaded for reference). I just can’t seem to figure out where that object needs to be connected to in order to record what is in the pop up window. Thank you for your time and help!

hello. you should check out the jit.gl.asyncread for reading gl contexts to a matrix for recording with jit.qt.record.

Also have a look at Syphon Recorder… http://syphon.v002.info/recorder/

Robert, I was just trying to figure out how to do this. Thanks for the info on jit.gl.asyncread!

Could you enlighten me as to why this isn’t working? I can hook up a jit.qt.record in the help file and all works fine, but this won’t.

@AaronMButler, your issue is probably simply remedied by setting the @layer attribute of the jit.gl.asyncread to some high value (like 100).
this tells it to “draw” last (ie readback from the buffer after all other objects have drawn).

Wow! Thank you so much Robert! I was able to capture the rendered material with jit.gl.asyncread.
