4794.0. "Realtime Picture Grabbing" by VERGA::MACDONALD (Home of Digital Realtime Pubs) Wed Jun 05 1991 11:30

    I would like to be able to capture a color image off my 8mm handycam in
    realtime using my Amiga. From there I want to take the image and
    transmit it over radio. The latter part I am all set up to do with the
    AEA AVT. Its the realtime picture grabbing that I need a solution for.
    
    Any ideas? I don't want this to cost an arm and a leg, and I would
    prefer to use one of my Amiga slots, since my video slot is in use.

    In decending order of $ needed:
    
    Video toaster 	$1200
    Frame grabber	$500
    Live		$300
    
    If your camcorder does stills, you could use DCTV or digiview with a
    color splitter.
    
    I have a framegrabber which does great real time captures, it will save
    images in all Amiga formats and will also save images in 24 bits format
    which could be viewed on a suitable 24 bit frame buffer (DCTV,
    Firecracker toaster...)

    What's the difference between LIVE and a Framegrabber?

    I haven't seen the frame grabber, but I have a LIVE for my Amiga 2000
    and for my 1000 as well.  Color and palette control is very difficult
    with the LIVE and the quality of a single grabbed image is not that
    great.  I have Invision Plus software ($200+) which lets me control
    those things such as color and palette much better and also has a still
    image capture routine that takes 4-5 frames and averages them out. 
    They turn out quite good that way from a videotape on pause or a still
    image (photo etc.) in front of the camcorder on the tripod.
    
    The main use for the LIVE is in real-time video.  With Invision, it
    lets me take the live moving image and manipulate it (ala Toaster),
    switch between two sources, and other neat things that look good in
    videos.

    The Framegrabber is by Progressive Peripherals & Software (PP & S),
    It can digitize a ham picture in 1/30th of a second (both fields) or a
    single field in 1/60th of a second.  The software to process the
    resulting image can take as long as 45 seconds (on a stock Amiga) to
    finaly display the results.  There are all kinds of bells and whistles
    to manipulate the image (expand, shrink, date and time, multiple
    images, multiple exposure, delta...).
    
    Unlike LIVE, real time ANIMATION is not possible, but image quality is
    superb.  I have done many tricks with modified images and the results
    were impressive when projected on a 9'x12' screen.
