record without recompression on pc


    Apr 30 2006 | 6:04 pm
    hello all,
    i am trying to grab and record to disk in dv pal through the jit.qt.grab object on a pc. i have installed winvdig 1.05, jitter1.5.2, max 4.5.7, the machine runs windows xp service pack 2. as video device i use a sony trv 900 or sometimes a dac-1 converter, both with the results below.
    i cant record to disk using the jit.qt grab object. as a workaround i could do it using the jit.qt.record object, but i want to avoid the recompression. when i set jit.qt.grab to vmode 2, the video input stops, i.e. the framerate goes up and it outputs no video any more. the same happens when i send it a write message, no matter which vmode it is currently in. the result of each recording attempt (after having sent write/stop messages) is always an empty qt-video file on the disk.
    as far as i understood, i need to use the vmode 2 to record without recompression, right?
    to me it looks like a hardware or driver problem, does anyone have an idea?
    thx for your help, dominik
