jit.xfade problem


    Apr 07 2006 | 10:42 am
    Hi All,
    New member and new user of Jitter - and enjoying it a lot.
    I'm putting together a patch so that i can take in 100 frames of video, have 1 play in the right direction, the other in reverse and have them fade into each other as the final effect (this will be reflected into a light box kinda thing)
    Anyway - i'm having problems with the xfade object; basically it look like whatever matrixset is going into the right inlet is not playing as a video when i apply a fade (it just displays the first frame of the video - or the last)
    Any idea of what i'm doing wrong? or do u think it might be a mermory issue?
    Thanks,
    Jimmy

      hi jimmy,
      your problem is that jit.xfade needs to receive a frame in the left
      inlet *for every* frame it's supposed to process. the way you set it
      up, you're only getting matrices in the left inlet when your left
      matrixset is being played. try to buffer the last frame on the left
      and repeat sending it to xfade when the right chain is active. how?
      well, that's for you to learn...

      Actually - J - i think ive fixed that issue but just noticed another that i'm sure should be easy but can't see a solution in the docs or forum.
      When running this patch for more than 20 minutes, the patch uses up all my hard drive space (about 2.5. gb free)
      Since i'm not writing to disk, this shouldn't happen - right?
      Do i need to clear the kill the grab object after every loop or something?
      Any advise would be great
      thanks again,
      Jimmy
