Hi all, I was thinking yesterday. (I know, watch out!:-)) I would like to get Digiview eventually and I would like to digitize pictures off of my vcr. The vcr is S-VHS and has a very nice pause. I know that you can digitize of the screen with a camara. I also heard that if you use a color spliter that you could digitize directally. Question one is, can I take advantage of the S-VHS resolution with a color spliter? And question two is, There is a svideo output on the VCR and the manual describes this as a seperated Y/C output. Is there a way to use this as input to the Digiview with out the need for a color spliter? As you can tell I am in the very early stages of learning video so any help is greatly appreciated.

But it isn't a good idea because most of the consumer-vcrs do only show one frame (and not the whole pictures consiting of one odd and one even frame) when they're paused.... So you loose half of the vertical resolution. I know this from PAL-machines, maybe in NTSC it's different..

Pretty poor results, I must say; then again, I wasn't using a color splitter or sync regenerator. I bet the B/W output of your VCR will give you better results if (and only if) it's just like B&W composite. The Panasonic camera that DigiView uses is a 575-line analog vidcon tube B&W security camera with 2:1 interlace and can generate internal sync. Try and come as close to this format as possible and you'll do alright. -- +----------------------------------------------------------------------------+ | Dallas J.

Try and >come as close to this format as possible and you'll do alright. A recent issue of Amazing (Dec or Jan) had an article on using an electronic color splitter with Digiview. The splitter used had S-VHS inputs as well as composite. Another question regarding Digiview. When I digitize in hi-res with my Microway flickerfixer board installed, I get some horizontal lines of noise in the upper 1/3 portion of my picture. With the flickerfixer board out, no noise. Is this a known problem? oo jj ww ww jj ww www ww jj jj ww ww jjjj Mel Tolentino (Watkins-Johnson Co. San Jose, Calif.) {{..!{hplabs,ucbvax,sun}!pyramid,..!decwrl!qubix}!wjvax!mel
