In Reply to: Upscaling from S-VHS and Laserdisc. posted by clarkjohnsen on July 5, 2008 at 11:00:45:
>>what can I expect from VHS?<<
Not much. Standard VHS has 240 scanlines, less than half of what a basic analog NTSC television is capable of (525 lines).
If you compare VHS video performance in terms of modern digital video, VHS "resolution" is absolutely horrible. Standard Definition digital is 720x480 interlaced (520 scanlines). VHS is equivalent to 330x480. S-VHS (and Laserdisc) bumps that up to a whopping 560x480 (420 scanlines).
"Upscaling" doesn't help much at all. These signals are low-bandwidth analog. Upscaling a low-bandwidth analog signal introduces lots of noise and artifacts.
IMO using a hi-def projector for these low-quality video sources is a waste of an expensive bulb. If you have tapes you want to watch, use your old analog tube TV.

- Thanks. But at least it works, right? (You're correct about the waste of course.) nt - clarkjohnsen 07:32:58 07/07/08 (0)
