I came upon The Wizard of Oz while casually flipping through the channels.
It was broadcast using The Soap Opera Effect.
I was stunned. It looked like it was being broadcast Live.
I ran across this again on PLUTO TV.
They have Gunsmoke & Andy Griffith episodes which look like they are NEW. Even though I’ve seen every episode of these shows, you end up wanting to watch them again.
The oldest shows look a lot better than the “newer” older shows because they were filmed, not taped. Therefore, they can go back to the original source for a print and they are going to be HD. Shows that were taped cannot do that when remastered - although they can still look much better if they would go back and use the master tapes for new prints. However, as AI editing advances, that may change. There are still old shows airing in re-runs that look terrible because they are still using the original, lower-quality syndicated prints that were for analog broadcasts but those imperfections weren’t nearly as visible back then.
