One cursed thing after having messed with analog video too much is that I now see how unrealistic all those "VHS" effects are that some youtubers love so much.
For example, they'd just overlay some horizontal stripes of noise on the image to show "fast forward". But, when fast forwarding a real tape, you don't quite see that — you actually see parts of several adjacent frames at once, separated by those stripes of noise, as the video head swipes across them.
Or they'd just add some noise as a semi-transparent overlay. Or some OSD text, also as a semi-transparent overlay.
But that's not how this stuff works! At least do it to luminance and chrominance separately to have any chance of it looking realistic.
OSD text should never have anything visible behind it. No real AV device ever does that. It's usually just black or white. Sometimes the surrounding colors can leak into it, but that's it.
