Before I say anything, I think any plain text people are going to be mad at
me, outlook has decided I want to use a bunch of formatting...  There is a
big vertical line I have never seen before, so I know this is going to give
some people problems.  Sorry.

want
        640*480, and a better VCR.
      A few questions:
    1. Did you set it up as FLC, MPEG, or what?
    2. How expensive a VCR adapter do you have? I've seen ads for <$100
units.
    3. How does the issue of "interlaced" apply to making an animation? (How
is it different, say,  from typical CMPEG output?)
    4. When I maximize low resolution images (certainly 160X120, probably
320X240) on my PC monitor, it looks crappily pixelated.  Am I missing
something? I would imagine 800X600 would be the minimum.

    I used adobe premiere to make a quicktime movie.  It is a video card
that has video in/out called a "video wizard"  it was about $200 for the
2meg version.  It can't really handle high resolution modes very well, but
as long as you have another video card for use on normal life, it works
great.

    NTSC video is at 60 fields / second, 30 frames / second.  I just don't
use the fields, and let the hardware figure it out.  It looks fine at 30
frames a second.  In other words, no fields= non interlaced.

    Don't know too much about 'typical CMPEG output'  so I couldn't really
compare.



    As for the resolution, NTSC only has 533  (?) lines of resolution
maximum, so you really aren't missing too much at 320*240.  If you wanted,
you could go up to 512*384  (I think)  for high quality stuff.  Think of it
this way.  Sit 6 inches away from a monitor.  No problem, a little close,
but perfectly readable.  Sit less than six feet away from a big TV.  Big
difference!  800*600 is overkill.  Some video out setups will allow you to
view 800*600 stuff on a TV, but they have to play big tricks on the image in
order to get it to stay readable.
