I have evaluate these graphics boards for the Mac,as you describe. Here are
some details.

1.RasterOps 364. This one is 24 bits.(not 8 bits).This bd can display live
video on Mac window,or full screen.One good advantage is you do not need any 24
bits graphic card separately as all other bds I tested need that.And this one
is only a one card (live video processing and 24 bit design). But if you do
processor(Mac) dependent work then video motion slow down,but still video is
quite good.

2.Radius TV. This bd also live video on mac window or full screen.Can change
8,16 or 24 bits resolution.(This is clever thinking). Can even insert text on
VIT(vertcal interval between fields).And also some video special effects.Only
RGB inputs. 

3.Targa card. We have bought this one.Very expensive as well. But live video is
very good. No window facility. You can display only on full screen only.RGB
inputs only.

Please note: For normal home use RasterOps come on top with price and simple
design. For serious research work you might decide Radius or Targa or SuperMac
which is not released to the public yet.
DOES ANY ONE HAVE ANY INFO ABOUT THESE BD'S RELEASED FOR AMIGA.
RasterOps told me they might do that for Amiga.
