LaserDisc stores the video signal in an entirely analog format on the disc, similar to a vinyl record but using lasers. In theory, under good conditions, the input signal is almost entirely reproduceable on playback (minus some degradation in the form of noise and dropouts).
The end viewing result should be something very close to the master tape that was used to make the LD discs.
DVD uses the same resolution and video format as LD but digitized, so it’s pretty evenly matched and DVD has better numbers on paper, but where it fails is its use of lossy compression (MPEG2) to fit all that data onto a disc which visibly degrades the image quality quite a bit. This issue is compounded because they chose to jam multiple episodes onto a single 4.7gb disc plus various extras and bullshit resulting in even lower video quality.
If only Paramount would get off it’s ass and make a BluRay release…
Yes I wish they would remaster DS9 as the documentary proved possible. But Paramount won’t sink any money in to it. I was hoping they would for Paramount+ like what HBO did with some classics. But alas, no
A full HD remaster from the film reels would be amazing, but even just re-digitizing the master tapes would give an improvement. That wouldn’t cost more than a team full of interns and some computers.
Indeed and equally perplexing considering how hot Star Trek is right now. You’d think they’d want it in high quality for the next 20 years of streaming/digital/tv rights etc
