Why'd they upload the SK show a second time? The new upload is better edited, and it was digitized at a pixel resolution of 1280x720 (HD).
But the most obvious thing you get out of that is black pillars left and right.
The rule of thumb for digitizing from VHS tapes is, use 720x480 or 640x480
depending on the source. Higher resolution is just interpolating up while
encoding more noise.
If you had a dub from the camcorder on Hi8, the math changes a little, maybe.
Converted to full-screen equivalents, interlaced analog video can do per-field
viewable resolutions ofโฆ
VHS about 240 lines
Hi8 over 400 lines
In the Luminance channel, not the color channels.
There are a lot of qualifications and exceptions.
So if the spec sheet told the whole story, which it can't, there could be
some advantage in digitizing a Hi8 tape at a vertical resolution of 720.
Then is the new version of the Shonen Knife show actually better?
Nope, not that I can tell. It looks to be encoded from a traded VHS
tape, and the extra pixels are the result of scaling. If you want to
scale it up, you can do as well or better by yourself on playback.
Also, the frame rate on the older upload is the original 29.97 fps, so
it's undergone one less minor transformation in the time domain.
