Just to add that the colorspace on those LDs is different from what’s used today on most devices (sRGB).

In fact, there are 3 NTSC color spaces, with the older ones having more information than sRGB:

And those LDs might even use the older (pre 1987) NTSC primaries ( https://www.saji8k.com/displays/color-space/ntsc-1953/ ), that give a larger color space than sRGB.

This is technical, but something to take into account if you are interested in preserving the original color timing.
You need to convert the colorspace to get that.

A quick conversion of the stills posted above to sRGB gives me this:

No clue on how to do it for a video file…
