Recording from jit.gl.render

November 12, 2010 | 12:04 pm

Hi,

i have a patch in which i render different shapes using jit.gl.render. When i make a window with the render name, it will directly render to the window. Now i want to make a recording of it, but this is not possible since there is no jitter-patchcord that i can connect to a jit.qt.record object. I have reprogrammed the patch so the jit.window is gone, and instead the jit.gl.render object renders to a matrix, with 800×600 dimension. This i can record….but it is extremely slow when recording, and when i want to check the recorded movie it seems to get stuck when playing. Although the complete movie is recorded, it can not be played and i don’t exactly know why. Should i use a certain codec? (jit.qt.record uses raw codec by default) or should i just use an external desktop recorder and not do this within MAX/Jitter?

Thanks for any help.

Okay, figured out myself that i needed to use a codec in the jit.qt.record thingy, JPG works fine. The default settings of jit.qt.record are no good. The recording is okay with alternate settings, and framerate is good.

also check out the jit.gl.asyncread object.
