If I understood the TOS situation correctly, or in other words if the people in the comment sections under those videos were correct, the Blu-rays are not source from the ORIGINAL negatives, as the promotional material suggests, but from new internegs created in early 80’s for syndication. That’s why they include unified opening credits (originally each of the first 13 episodes had slightly different opening credits) and fixed some of the effects scenes, like the planet shots in The Naked Time.
Harmy - a quick question - so are the TNG episodes available on Netflix in whole Europe? Do they contain the fixed versions? http://trekcore.com/blog/2015/08/netflix-brings-vfx-fixes-to-star-trek-tng-in-hd/2/ I’ve been searching for the fixed episodes for years, so if they are indeed there maybe I can finally have a reason to get Netflix myself.
And by the way, not ALL of the effects were done on video. Only Dan Curry’s team apparently shot effects on video at 30fps, Rob Legato’s team and definitely ILM were shooting them on classic 35mm film.
Well, on the making of documentary for the TOS blurays, they’re definitely handling negatives. Beyond that, I have no idea why there are tiny differences between the two.
For TNG, the only effects that were “video” were the early CGI and phaser shots (maybe others as well). But Dan Curry definitely shot on film but at 30 fps which caused some issues for the remaster since everything was done at 24 fps instead of 30 fps of the video masters. You do see some weird artifacts, but unless you’re really staring at it, it’s fine.
And the reason for recreated shots of the ship were because they would often be missing an element like a light pass or a matte pass and it would have been too difficult to recreate the missing pass in CG so the entire shot would be replaced instead.
