Composite-RGB splitter? (Mostly pertains to IV24)
--SeebS--
I recently spent about an hour mucking about with a Sega Genesis and my
impact vision board.
I can not get the composite to genlock behind the amiga in color. If I
pass it through to a 1084 (like, IV24's composite out), it looks fine,
but the 3000 can only get sonic (the hedgehog) in black-and-white.
I have been informed by a video friend that what I need to do is get
a composite to RGB color splitter, a gadget he says may cost as much as
a thousand dollars...
Does anyone know what I need to get composite video to genlock behind the
amiga display? Does anyone out there have much experience with using
IV 24 for such a trivial purpose?
Just so people know - my goal here is to be able to run sonic as the
"background color" on my 3000's screen, but still have hires-interlace
non-flickering graphics. Does anyone know if this is possible? Does
anyone know if this is even remotely likely?
I know this is a sort of stupid use for such an expensive piece of hardware,
but I really don't want to run the sega through the 1084 I use on my unix
machine, so I wanted to use this genlocking capability. I don't have a VCR
or a TV or anything silly and non-processing like that, so that's not an
option here.
Help!

I use an amiga because it works better than all the other machines I tried.

I have seen a composite PAL/NTSC to VGA converter in some ordinary clone
seller store (you know: those "all similar, name different boxes" :), for
about $80 canadian, made in Taiwan. It has 3 composite input, and a switch
for both audio,and video switching. It is not the composite in a window
type on MS-DOS/Window stuff , which is more expensive, it blocks out the
VGA passthru signal, when composite is on.
The main question is if you can do more with this gadget, anyone?

I have an IV-24 board in my A3000, and I also have GVP's color splitter. Now
you need the splitter to display external video on your RGB monitor, but, if
you use a composite monitor, it might not be necessary.
1st case with splitter : connect your Genesis' composite video out (not RF)
to either CVS-1 or CVS-2 on the splitter, in ivcp's Video Interface menu,
select the proper input for video and sync, then select genlock mode.
click on reboot, when Amiga has booted, press Alt-F6 or use ivpip, and enjoy.
just note that this allows you to use the flicker-fixer that's built in,
without splitter you would have to use interlaced video.
2nd case without splitter: I assume you have the cable to connect to the
IV-24's 26pin connector which came with the IV-24. Identify the leads for
composite video in and composite video out. Connect your monitor to the
composite video out, the Sega to CV-in, then set ivcp to video-scan, genlock
mode. Now try using ivpip or press Alt-F6.
I'm not sure whether the Genesis has interlaced video or not, if not, set the
Amiga to non interlaced too. looks better.
have fun.
