VHS is about 240 lines horizontal resolution and 40-50 lines chroma resolution.

Even at 1440p the video has massive MPEG blocking, it's been heavily compressed after being captured off tape. VHS has not got MPEG-like compression.

https://www.youtube.com/watch?v=8K8dUkeDZTM is an example of a badly-worn and therefore extremely "speckly" and dull VHS tape that I captured a while back. Youtube has a hard time with the chroma noise, but I didn't want to overcook it with denoising etc. so I just left it as it is.

Notice how much smoother everything is?

https://www.youtube.com/watch?v=ZPmCygZIjio is a capture of a very damaged Sony 8mm analogue tape, again with a lot of dropouts. Notice how there's no MPEG blockyness?

These aren't even especially good captures, and were done off a not-properly-set-up "industrial" VHS machine which desperately needs realigned (and probably new heads), into a DV camcorder used as a DAC into a Firewire card.
