Better VHS emulation and VCR Emulation #58

Open Degamisu opened 3 months ago

Degamisu commented 3 months ago

i was using a portable VCR when i realized it had a little worse quality than my Toshiba VCR Plus + VCR. I was thinking that you could add this type of emulation.

The VHS speed config doesn't do much. The slower the speed, the more distorted. this is also dependent on the VCR, as the Toshiba can handle slower speeds well, while the portable cannot.

This isn't really actionable without frame captures of the different VHSes.

The VHS tape speed setting is only meant to adjust the maximum frequency that can survive encoding--as the tape speed decreases, the bandwidth does too, so the image gets blurrier. You can use the other settings to emulate different VCRs. If some settings are missing, you should provide some visual examples.

63 is one of my other suggestions, it kinda falls into this.
