voodoo47: those are just upscaled versions of the originals - no benefit in using them, actually.
I'm the one who made the upscaled versions, and if you actually viewed them you would see there is a marked improvement. The videos weren't just changed in resolution, I went through them, upscaled them significantly, processed them to remove artifacts and other impurities, and downscaled them back to where they are now. You can notice the difference, and most people have said as such.
I still have the original upscaled versions (including a slightly larger and less compressed version), I'd be happy to recompile into a zip and post somewhere for people to obtain if the site they are trying to get it from is making it difficult.
Just to be clear, I only changed the 3 major cutscenes (CS1, CS2 & CS3), I didn't do any of the short ones.
If people go into their cutscenes folder inside their shock installation, you can play them. Take note that the credits cutscene is actually a higher resolution than the other cutscenes. (640x480) That was the size I upscaled the other cutscenes to for sake of continuity. (and let me say it was a pita to encode these because of the archaic codec the game uses.)
Anyway, if anyone has trouble getting the upgraded cutscenes, or would like me to upload the ones I have with slightly less video compression, just let me know and we can find some place for me to drop them.
