I have an Amiga 2000 with an A520 RF adaptor hooked up to it with the intent of making S-VHS graphics on a JVC 6600 SVHS VCR. My tries at recording so far have had varying degrees of success. The picture on the monitor (showing the signal going through the VCR) is usually quite good. However, when I tape the picture and play it back the colors look mottled and the resolution suffers. I am using good quality hookup cables, the VCR is new and the tape are new. I don't really want to spend $1000 or so for a S-VHS genlock; al I want to do is to record Amiga graphics onto videotape – preferably in SVHS format because of the better resolution. Any help or suggestions would certainly be appreciated. Jim Earl

Jim, when using an RF feed to your recorder, you are limiting resolution to a maximu 320 lines of horizontal resolution- about equal to Low Res- and not as good as your recorder is capable of. One of the problems you are probably having is bleeding and dot crawl of your colors which is also an artifact ofnot having Y/C SVHS feed to your recorder and further encouraged by the degradation caused by the RF modulation. Given your hardware, the way to improve your pictures are to keep your colors less saturated, and reduce your brightness levels (settings in the palette requester in DPaint should not exceed 12 out of 15 on the slider scales) Also, only use interlace modes for video recording as this corresponds the actual TV signals that the recorder is expecting to see. Unfortunately, the full potential of your SVHS deck cannot be realized without a genlock or encoder that will Amy's RGB to Y/C directly. But even recording a csite video signal instead of the RF should make some improvement if using a good encoder or gek. Good luck. The Amiga makes great pictures, but getting them to tape faithfully requires a good genlock or encoder and I haven't seen a cheap one that does Amy justice. Chris
