Re: How to capture quality images from a IIGS?

Hello all,

I have a video project I'm working on and will be using some hand-
drawn graphics that were generated a long time ago using the Apple II
program Dazzledraw.  I have an Apple IIgs and was hoping to find a way
to capture the images with best possible quality so that they could be
imported to Final Cut Pro and worked into a standard def NTSC
timeline.

I wanted to output the images using the RGB port and get the same
approximate quality that you'd get while viewing on an Apple RGB
monitor.  But instead of going to a monitor, I'd like it to feed out
to a video capture device.  I could go with still image captures, but
I really want to capture as motion video straight from the IIgs,
because Dazzle Draw has a slide show feature and I'd like to get not
just the images, but the original transitions and wipes that the
program uses with its slideshow feature.  Does anyone know of a way to
go from RGB to Component or possibly s-video, etc. while maintaining a
clean video signal.  Not interested in composite - that'd be too easy
and not clean enough.  Again, this must be NTSC.

The best that NTSC is capable of is good quality composite--which is
by definition NTSC--a bandwidth-limited standard for video broadcast.

So you actually want an _extension_ of NTSC which provides greater
chrominance and/or luminance bandwidth while maintaining the NTSC
scan standards.

An RGB-to-component converter is your best bet, and they are available
from several sources on the web.  Unfortunately, they are not a volume
device, and so they tend to be well over $100.
