How do I record output from jit.playlist?

I tried using jit.record, but I get a message in the console that the avf engine is not supported. If I can't record in jit.record, then where can I do it???? I do get files out of the process, but they are mostly gibberish...

Avf engine is not supported for Windows OS yet. Although you can try the old fashioned max way aka jit.qt.record. Look at jitter tutorial 19 as also jit.gl.render-tomatrix example (you have to render to texture your movie first) . Unfortunatelly for me (2.2 GHz, 4 cores i7) extrernal video recorders can do a better job.

I'm running on a Mac, so the AVF support is not a problem. The problem begins when trying to record into jit.record or jit.qt.record. I finally figured out how to go back to the qt-engine, but the performance went way down, and the patch crashed almost immediately. OK, so maybe I work with too many 720p videos in the playlist or something, and it's all too heavy for Max to handle?

hi kflak.
the jit.record errors are a bug that slipped in to the release, and are fixed for the next release. however in the meantime, the object should still function as expected, and the errors can be ignored.

if you are unable to get a proper recording please post your patch.

Here is the patch. I am still not sure if I'm simply loading way too much content into the playlist object, 16 720p movies of varying lengths? Or should I expect this to work on a macbook pro 2,6 ghz i7 2013 model with 16 gb ram?

Ooops, sorry, mistake with the patch. Obviously the vizzie recorder doesn't belong there... Here the correct patch.

it doesn't look like you're sending a matrix input to the jit.record, so it's not actually recording any frames.
try out the jit.record help file and see if it produces expected results.

Yeah, the lacking patch cord was just a little hickup from when I swapped back to jit.record from the vizzie recordr. Sorry about that... I reconnected jit.record now to the output of jit.op, and it is crashing happily again. The jit.record helpfile works as expected on my system.
