delay time


    Aug 18 2006 | 11:05 pm
    Dear List,
    I am making a video interactive installation. I use a DV camera(Canon
    DM-XM2) to catch the image behind the screen and sent it to a projector
    opposited the screen. Now I got a big delay problem with the DV camera. It
    cause the interaction can not happen accurately. By the way, the lowest
    resolution of the DV is 640* 480. I am wonderring what the normal delay
    time will be?
    Any help would be appreciated very much!
    Best,
    Xinmei

      What do you mean? Version 3 of the driver was released last week (and
      was beta tested in Jitter UB).

      so to answer your question Xinmei, you will need to use a non-compressed video source like the DFG/1394 Video-to-FireWire converter ($350) or the Unibrain Fire-i camera ($100) to cut out the delay.
      good luck!

      You can also use an ImagingSource camera since it is uncompressed as well.
