I see people will offhandedly reference the fact that multiple video masters for the trilogy exist. Does anybody know how many home video masters exist for each movie of the original trilogy?

The two I can name are:

The original 1982 that sourced first VHS/Betamax/Laserdisc release (Star Wars only)
The frequently-cited master used for the definitive trilogy laserdisc box set, later repurposed for the limited edition DVD.

I’ve seen people suggest that there are more than one pan-and-scan master for certain films (citing bits being reframed). I’m genuinely curious to have all this knowledge pooled together. Thanks!
