I try to use jit.qt.record for capturing, but I get only low quality at low framerates.

I originally used jit.qt.grab directly for capturing. That worked actually fine, but with strange delay as you can see here:

My project is all about good timing... I basically have to capture some scenes of a person in a greenbox. The person is doing 3 different actions and I have to record one clip for each action. I thought in the worst case I have to record the clips to disk then open them immediately in the max patch and then somehow set the in and out points manually and then export... I seem to be very desperate right now :)

I capture 720p 50 via a Blackmagic Card.

Not sure I can be of help, but have you messed with the jit.qt.grab settings like vmode? I'm not sure what's causing the delay but I think I recall a project where the compression was slowing down the capture.

What codec are you using in jit.qt.record? This would have a big impact on performance.

Alternatively, have you looked at jit.matrixset?
