Hi, I have an Amiga 3000/25 and DCTV, and have a few tips for fast animation
with it.  If you must have full screen animation there are a few sacrifices
you have to make.  Apparent resolution is a product of screen resolution,
colour, and speed.  I you give up some of the first two, the speed of the
resulting animation can make up for it.  The following will speed up
animations:

1. Turn off overscan.  If you do this, you will only have to move 69% as much
   information.

2. Switch to 3-bit plane mode.  You will never notice the difference if you
   are doing something fast like a canyon fly through.  You will notice the
   drop in colour though, if you have an object which is stationary or moving
   very slowly.  You only have to move 75% as mush data in this mode.

3. Switch to a non-interlace mode.  I'm not sure about the quality of
   non-interlace for recording.  You might want to run dolace, or some such
   program before recording.  Once again, the drop in resolution is only
   noticeable in object with little or no motion.  You only have to move 50%
   as much data.

So, if you use all three, you have 26% as much data as an overscan, interlace
full colour animation.  Once again, this is assuming that you are doing a
full screen movement style animation.  Using all three of these tips, I get
at least 25 fps no matter how complicated the animation is.  I have an
animation created by digitising all the frames of the sceen in Robinhood where
the arrow flies through the trees, and it looks like a video tape (minus the
overscan).  Remember, film is only 24 frames per second, as is PAL video.  That
is all you need for convincing motion.

I hope I was of some help.
