metro problem


    May 07 2008 | 6:27 am
    Hi, all,
    I'm working on a patch that uses two variations on the same video, one controlled by a metro that is activated only when it receives a certain amplitude from an audio track, and the other that is running on a normal metro 40. The audio-variable movie is chromakeyed so that the normal movie shows through it in certain areas.
    My problem is this:
    Because jit.chromakey is controlled by the chromakeyed video's metro (the audio-variable movie), the normal video is also subject to the starting and stopping. I don't want this. I want the normal video to play normally, and the audio video to play in the sporadic, glitchy fashion that it does.
    Apologies for the convoluted wording, I can post the patch if necessary.
    Thanks for any and all advise!

      send the left input into a jit.matrix before the chromakey input, then trigger bang that matrix every time you receive an input to the right input.
      like so:

      should note, fwiw, probably more efficient to use the "frame" message to the jit.qt.movie to achieve the jerky effect.

      Thanks for all the responses, I really appreciate it! That patch really helped, though I'm confused about one thing. When sending out a tbl, what is the list doing? I'm not familiar with that method, I'd appreciate any explanations.
      Thanks again!
