Multiple Exposure Effect

    Jan 26 2011 | 12:59 pm
    I would like to extract multiple frames from a video and combine (say via add) them in one image. I need to be able to control the extraction time interval, the number of extracted frames, moments of extraction, etc.
    The effect I have in mind is similar to this:
    How should I go about it please?

      jit.matrixset can be a good starting point to grab and store the frames from your object... take a look to the help file and you will se how easy is....
      to do the combination maybe with a jit.op chain......?
      good luck!

      Sounds like you want a sort of feedback chain that you can switch on and off, but you probably need a threshold too. Even when things are totally dark, camera noise will build up in the feedback chain pretty quickly. Matrixset could be a way to play with it as well
      See if my lightpainting patch helps you at all: ...and then come back with something you've tried and we can probably help expand it
      My example isn't as clean as some of these other live video lightpainting ones..I've always wondered how they get them so clean
      jit.wake can be pretty fun too..or jit.slide

      That link was a blast from the past. My dad used to fly those funky things. He said the big bananas were the worst, like two choppers tied together with a string.
