forcing jit.window to black


    Apr 08 2008 | 6:41 am
    I am making a video player and want to be able to force the jit.window to black. I know that it can be done easily on a jit.pwindow, but I am using a jit.window. There are klugey ways to do it, but I am wondering what people think are the most elegant.
    Thanks.

      i use a bline powering a jit.op @op * for a slow dimmer.

      No, I'm not using openGL currently.

      I'm definitely looking for a cut to black. This will be in response to an external command.

      eh, depends... what's playing in yer window? you can alwaqys just send it a "black" matrix (one with all cells set to 0 either by default or by "setall 0 0 0 0" msg to it)

      can't you also just send the matrix a "0"? I believe that should work too.

      As people have pointed out, there are many ways to do this. By far the fastest and highest quality solution will be to use opengl with jit.gl.videoplane. You can get a real simple fade to black by enabling blending and setting the alpha to 0.

      I'm playing back a straight quicktime movie. Since I'm looking for a cut (not a fade), it sounds like creating a black matrix and sending it to the window is probably the way to go.
      It'd be useful to actually have that as a window property. I can think of several instances where I would want to blank a window.
      Thanks all.

      Perhaps, but I would call this feature creep. It's way to easy to do without such an attribute to merit its addition.

      I guess it's because I come from a hardware perspective, so I am viewing this as a player/screen. Every hardware video player (and just about every projector and screen) that I work with has a "video black" feature and we use it pretty extensively. To me, it's just standard.
      I don't really care. It's not a big deal.

      my solution to this and other problems was to create a QT player patch that has drop file, color & contrast control, scrub bar, audio level control, speed control and fade & cut to black with audio follow. slap it in a bpatcher and you're off. i found out quickly that building your own "hardware" was pretty great. b

      This is a very simple solution, and I don't think it's a kludge. Seems pretty normal to me, maybe even simple enough to be "elegant".

      Strangely, in my original patch, something was causing the window to buffer the last frame, so "clear" to jit.qt.movie was not clearing the window. I need to do a little digging around to see why.

      this is still a stupid-hard problem to solve. and no, you cannot just send a '0'. trying to figure out how to use gl...but seems so ridiculous, just to cut to black for a bit! 'clear' isn't working on jit.window.

      What's hard about sending a full black matrix, or crossfading to one?
