The reason why I was interested in video essentials on vhs was because I would want to compare vcr's in their playback. Some of my videos only exist on 2nd generation vhs tape so I want the best possible quality. Lately I see that someone on the video help forums has posted the JVC SR-W5U is the best vcr ever made. The Panasonic AG-1980 is also highly regarded. I am not sure about using the time base corrector, is it easy to switch off on those machines if I want? I'm afraid of permanently introducing side effects from "correcting" tape playback (similar to the DVNR on the Star Wars THX laserdiscs). I'd feel a lot safer doing noise reduction in post. Besides, I've captured a section of Hi8 video with the camera's TBC on and off. I used an s-video connection for both but this part of the tape was recorded in the camera's LP mode.
With TBC [url=http://www.uploadfile.info][/url]
TBC off [url=http://www.uploadfile.info][/url]
I think it looks better without TBC as the colors look even more washed out. And I was only interested in deinterlacing still images like the ones above for display purpose. At this point I'm content to have the video stay interlaced. Even something that could resize the image vertically to half size but keep the full horizontal resolution would be good.

If it's one of the best, it should have a switch to shut off signal processing, but keep the TBC. The TBC is to get every row starting on the same column. Without one, each line starts in a random place (within a short range), fuzzing things up. Yeah, you wouldn't want the hardware pretending to clean up your signal.
A TBC wont help a 2nd-generation tape, though. The damage is already done.
I remember an old version of Corel would let you pick a field, then it'd enlarge horizontally. It looked like crap. I haven't looked for the option, since, so I don't know. Don't remember what it was called, probably something to do with deinterlace or remove interlace, or field-something. It might've possibly helped if it would let you resize it yourself, but it insisted on automatic.
On deinterlacing video, I was thinking about doing a temporary copy and picking the frames out of that. I think you'd want to double the framerate, then each field would become a pretty-good looking frame. The deinterlacer's job would be to invent a new matching field, by tracking the previous and following fields, and making a new one that lined up with the current field. Now, I don't know, because its meant to look good in motion, but I'm pretty sure it would look a lot better than a simple resize.
Wish I could tell ya more.
One day I found... 10 years had got behind me. Next day was worse.
