I've read a reasonable amount about the various Genlocks for the Amiga. It looks like one needs to spend at least $500 to get a decent output. (From Amigo Times article). Now, I DO NOT NEED to sync external video output to computer graphics. At least, not yet. All I want to do is to record my TS 3.0 and other animations to a VCR. So, what I need, but have not seen, is a comprehensive list of the RF Modulators available for the Amiga. I know Commodore has one, and I have used the one put out by CMI. I would like to see the output quality examined and each model compared with the others. Has anyone seen an article like this? From the price of the low-end RF versus the price of a low end Genlock, I would expect that one should be able to find a "broadcast quality" (or as close as the Amiga and the peripherals can get) RF Modulator for less than $300. Any comments would be appreciated. Thanks, Scott Sutherland sutherla@qtp.ufl.edu

Why do you want to go to RF and take the ding in quality letting the VCR convert that back to video? Seems like it's a lot cheaper to just take the composit video out of the Amiga and pipe it to a VCR... and probably better quality than going to RF in between. >Thanks, >Scott Sutherland >sutherla@qtp.ufl.edu >----------

You can connect the A???? that way, bu you will get a Black&White picture on you screen. The Amiga send out only black and white information on the composit_video output (unfortunately). I don't know about the modulators, but i think these will output color. (This applies to PAL Amigas. I don't know about NTSC Amigas, but i suspect this will be the same) -- ___ ___ ________________________________ / \ / \ / \ | | | | Beware, everything you type can, | | O | O | | and will be used against you ! | \___/ \___/ \________________________________/ | \ +------------------------------+ | \ | Jan van Veen, | | _____\ | beo@maestro.htsa.aha.nl | | | | Amsterdam, the Netherlands | | | +------------------------------+

I'm not real jolly about the shape of the sync, and the greens come out pretty weak. Note that you get in even a worse spot if you accidently try to use non-interlace, real play back problems. I'm much happier with the output of my mimetics genlock. Much sharper green, and I can get the sync from elsewhere. Problem is, I can't always borrow somebody elses VCR for a sync generator. Does anyone know where I can get a cheap, but healthy, sync generator? Heck, hardware doesn't scare me, anyone with a good schematic? I'll probably have to ground & shield it to get a nice clean signal, but I'm willing to go the distance. /* Jim Hutchison {dcdwest,ucbvax}!ucsd!celerity!hutch */ /* Disclaimer: I am not an official spokesman for FPS computing */

If you have a later model you can buy a device that will give you composite video in color. It's probably more expensive than an RF modulator but I'm sure the quality will be much better. If you're going into a VCR you should definitely look into it. If you have an A1000 all you need is a length of coaxial cable with an RCA male plug on each end. --Fabbian Dufoe 350 Ling-A-Mor Terrace South St. Petersburg, Florida 33705 813-823-2350 UUCP: ...uunet!pdn!jc3b21!fgd3

I'm sure this has been hashed and rehashed on the net before, but I missed it, so flame me if you must: Why did Commodore remove the color from the direct video output on the 500 & 2000? Dan Howell <dhowell.escp8@xerox.com>

Aside from any expense consideration, a b/w signal can be as sharp as the rgb format, but a color composite signal can't. So if you don't want color you can buy a cheap monochrome monitor and still use 80 character lines, which would be fuzzy if viewed in color on a normal tv. On the other hand, if they had kept the color video out (per the 1000), you could use a monochrome monitor at "full sharpness" by making an adapter plug for the rgb port which would just take the green signal (I'm pretty sure the green has sync on it) and set your preferences with that in mind. -don perley perley@trub.crd.ge.com

The Amiga 1000's all output color information over their composite outputs and therefore work quite well without an RF Modulator. However, 500's and 2000's only put out B&W images. In fact, certain 2000's I've seen don't have a composite output at all (some European models!) -- Mark Vange Phone Death Threats to: PAS Systems - "Plain and Simple" (416) 730-1352 mark@xrtll 8 Everingham Ct.
