1272.0. "Animation & Music" by FUTURS::LLOYDN () Wed Mar 25 1992 06:21

    
    
    Hi all,
    
    I've been fiddling about with animation, using the cyber set of
    proggies, which are pretty good, IMHO.
    
    Now what would be nice is, if there was someway of adding a music/midi
    sample as a background to my animations. For example a nice video
    title animation and a little tune being played in the background.
    
    WOW !!
    
    
    But how do I do this. I've looked at an Amiga BLAH !! mag. and in their
    they have numurous genlock devices, for use with videos. Forgive my
    nieveness but what is a genlock and are they available for the ATARI.
    
    I look forward to your replies, and help

1272.1GENLOCK in a nutshellPRNSYS::LOMICKAJJeffrey A. LomickaWed Mar 25 1992 15:4520
I can't help you with animations.

GENLOCK is a term used to describe the configuration where the video
display generator get's it's sync signals from an external source.  In
a television studio, all of the equipment must be in frame and scan
synchronization so that you can mix multiple input sources onto the
same display, and switch from one source to another with no visible
interruption as the TV receiver resynchronizes.  GENLOCK capability is
required to allow an EXTERNAL sync generator to dictate to the
computer's display controller when the video sync events occur.

This can be difficult, because in a computer usually the sync is
synchronized to the computers master clock, so that memory accesses can
be performed at the most optimal times.

The STe series of Atari computers has latent support for inexpensive
GENLOCK capability, waiting for a third party to make such a thing.  The
capability is discussed in the developer documentation for the STe,
which is now available to the general public (for a fee) as well as to
the registered developers.

    Many tanks Jeff, I'm slowly getting to grips with all the weird and
    wonderful gadgets available.
    
    Just for your info. there is a company here in England that imports a
    GENLOCK device from Germany (LABBBROKE COMPUTING), which costs about #250, 
    perhaps somebody in Germany can enlighten us.
