Saw that video and pretty much flipped...there's a huge thread over at the classic horror film board that goes into detail but I noticed the "fixed" title cue is actually a different recording, as was on the Spanish edition. All they needed to do was to pull the music on the opening titles of The Mummy, which utilizes the exact same Swan Lake recording as Dracula!!!
The image will likely be over-manipulated as it was on the last 2008 Legacy DVD release, which had the image overblown with brightness and contrast tweaks so that no shadow or darkness remained at all. What I'd like to know is what source was utilized. All I know that Universal has is some fine grain print stuck for TV broadcast prints in the 50's. And the fact that they're just printing the audio onto another 35mm print shows that they aren't going from the original Vitaphone sound discs that have been floating around for years. (This is where the restored "Now I know what it feels like to be God" dialogue came from on the '04 Legacy DVD of Frankenstein-from a collector's disc copy.)
And why is it necessary to de-noise and de-hiss the film? Have they never seen Dracula? The Vitaphone process was not great for sound quality, so the inherent noise should not be erased as it contains valuable dynamic range. But they will do this likely to provide a "cleaner" track. Damn it, the hiss has become part of the film's legacy-just watch any condition copy of Dracula on a big sound system with the sound cranked in a very dark room...and tell me you aren't a bit creeped out.
At least there isn't going to be a 5.1 remix...but I can easily foretell that this box set is going to give me some massive headaches. Universal hardly wanted to do this at all, so they chose the big titles as a test run. They think people won't buy arguably the most famous Universal franchise in HD. Hmph. You'd think they'd finally bite the bullet after all these years and do full scale nitrate transfers with full attempts made to present the films uncut and with the missing bits intact, such as the original ending to Dracula of which the studio has the footage. (but no audio track.)
