jit.record goes crazy in certain resolutions

    Mar 08 2017 | 6:15 pm
    I'm noticing a very strange behaviour with jit.record: in certain resolutions, it goes completely nuts and the recorded video is completely distorted. It looks like a bad use of jit.scanwrap with straight lines becoming diagonals. The curious thing is that it only happens in specific resolutions. In this screenshot (http://imgur.com/a/j0LQs) one can se, in the left, the video rendered with 405 x 540 and, in the right, 810 x 1080, which is the resolution I want.
    I'm working with jit.gl.asyncread but it seems that it's output is perfectly fine, as I have checked with jit.pwindow and jit.matrix. I've also tested with the matrix output of the jit.world straight to jit.record and the same thing happened. I'm on a Mac Retina 13", but have also tested in a 15" computer, latest Max version, avf. The only way to solve this issue seems to be to use qt as video engine in 32 bit mode and with limited codecs, which is far from ideal.
    This is something that I have noticed a long time ago, but now I'm really depending on it. Any ideas on why this is happening or if there is a solution?
    (I know that the common solution for video recording in Max is Syphon, but I'm working on a project in which the recording is also controlled by the patch, so I'm going with jit.record or any other possible Max solution).

      Hi, Rob. As the original patch is ultra big, I have reproduced the problem with this small patch:
      And this is the result: http://imgur.com/a/g4kvi

      Rob, I'm curious: any news about this? Is it really a bug? Also, if there is some other testing you need to be done, count me in!

      I thought it was fixed a few months back in a Max release. Is your Max version updated?

      matheus you're totally true. Had a little bug, that caused kind of the same weird distorted video. thanks for you quick response.
      best c.
