NTSC video is 30 fps, 512.5 lines vertical (about 480 of which are actually
visible on the screen).

DCTV is a composite device.  It is somewhere between 18 and 21-bit color.

I think your Mac dealer is misinformed.  The Amiga has tons of software for
animation and multimedia (ask your local cable television supplier).  Plus
if your budget is a concern, you can get a lot more bang for the buck
as far as multimedia goes with an Amiga system.

Bear in mind that the Amiga system with SCTV will not need anything else
to put it on videotape.  The DCTV will connect directly.

The Amiga has no trouble with full-screen animations, whether from memory
or from hard disk.  And if you want to create animations for videotape, plenty
of software exists that will let the Amiga control your tape deck for putting
those animations on the tape a frame at a time, if you so desire.

Again, I think the Mac dealer is misinformed.  On the Amiga, you could get
a *good* set of tools for multimedia for your $500 software budget.  The
DCTV comes with a pretty good paint program.  The Amiga comes with AmigaVision.
Then you'd probably want to add Deluxe Paint IV (mailorder is about $100), and
for your 3D modeling and rendering you'd want Imagine 2.0 (mailorder is about $200).
You can get any of several good sound digitizer/editor/sequencer packages for
about $100.  Your software dollar goes a lot further on the Amiga than it does
on the Mac.

The Amiga's multitasking OS is not the same as the Mac's System 7, but
I won't get into that or someone will scream advocacy.  The demo the Amiga
dealer gave you is typical.  My Amiga (an A3000) is constantly doing
something like this.  You can even play your full-screen animations at full
speed while doing all that other stuff (yes, I have done this).  The
Mac will not be able to do this as well, since disk activity will
interrupt anything else that is running (including your animation).

I won't argue that public perception of the Amiga isn't exactly great.
But that doesn't make the machine any less capable, especially for
multimedia.  (Again, ask your local cable company how they feel about
the Amiga for video work.  The cable folks I talked to here have a room
full of them, many with Video Toasters, and love them all.)

Software does exist that allows Macs to play Soundtracker
files, though the ones I heard didn't sound all that great on it.
Be aware that SoundTracker is an Amiga program, so the Amiga can
play those files quite well.
