[comp.sys.amiga] Professional Amiga Video Production

thomas@eleazar.dartmouth.edu (Thomas Summerall) (12/01/89)

Several friends and I are starting a video production company and would like
to be able to generate our own broadcast quality titles and also combine, if
possible, animated graphics with video.  I am hoping that we can find a PC to
fulfill our needs because we don't have the money for a Chiron, and don't
wan to rent suites.

We have to decided to go with S-VHS because of obvious quality/price reasons.
Now we just need scan converting/genlocking systems that use SVHS.  I have
looked at both the Mac and the Amiga, and the number of products available for
the Amiga is too great to ignore.

Now I have several questions.  Can the Amiga produce broadcast quality titles?
In other words, minimal flickering or bleeding.  What is the best software to
use for this.  Who makes the best SVHS genlock?  I realize that the A2000 is
designed for video in many ways, but the graphics seem less crisp than those
on a Mac II.  This mainly seems due to the very noticeable gaps between horiz-
ontal scan lines.  Is this a function of the monitor?  The video circuitry?
Perhaps this allows greater NTSC Compatibility?

I would appreciate any info, particularly from those who have set up their own
production sites and can steer me away from the low-quality stuff.

Thanks, and I hope to be posting as an Amiga owner soon...

Yes, with the right equipment.  The low and midrange genlocks won't do it.
Look also at framegrabbers.  You only need a genlock if you actually intend to
combine video and computer signals in the same image.  The Magni is made by a
video company and is worth consideration, as is the Niriki.  Don't expect to
pay under $1200 for a good genlock.  But consider also that they will hook
directly into the Amiga without yai (yet another interface).  You will probably
also need to consider getting a time-code generator.  Can't remember if the
Magni and/or Niriki generate all the timing information necessary.  TV New
Zealand is using the Amiga, as is Danish TV, Dutch TV and a lot of US Cable
Companies.

The 'crispness' of the graphics is very much a function of the monitor and
dependent also on whether the signal is interlace or noninterlace.  Get
yourself a flicker-fixer ($495) and your Amiga picture will be rock solid in
beautiful color, but remember that video wants an interlace signal (your eyes
just don't like it much).  Yes, it allows greate NTSC compatibility, that's why
it is cheaper to 'video-ize' an Amiga and why so many professionals are
selecting it (and University Visual Communications and Broadcast departments).

Reds are traditionally problem colors in video.  Remember that video legal
colors are of lower intensity than those which can be displayed on the monitor.
Keep your intensities to a maximum of 12 (a la DPaint's Value slider).

There is an abundance of useful animation and titling software for the Amiga
and more coming out all the time.  Have you looked at AV Video Magazine?  It
has at least one and sometimes two articles on the Amiga each issue (Montage
Publishing, Torrance, CA).
