Zombie Lake comes framed at a ratio of 1.64 while Oasis of the Zombies measures in at 1.65, and I doubt either could ever look better. Zombie Lake fares far superior, but both come with the expected hairs, scratches, and white specks. Since they have both been remastered from 35mm elements, a lot of the runtime of both films look really good. A lot of Zombie Lake even looks like a brand new film with incredible detail and sharpness. Oasis of the Zombies has more issues with its picture stability and the opening credits are shaky with tons of blurry shots of a continually appearing spider in its web and a painting that seems to be continually used as an establishing shot. There was also some serious banding in a scene featuring sun glare so bright you literally have to shield your eyes. I seriously doubt either film will ever look much better than what Redemption has issued here and fans of both directors should be extremely pleased — especially when it comes to Zombie Lake since it features far more of the expected T&A.
The audio on both features are PCM 2.0 French or English with English subtitles. Both have their issues with Zombie Lake still the better of the two. Watching both films back to back this comes as a surprise as Oasis was filmed after Lake and appeared to have a bigger budget, but apparently none of it was spent in the sound department which makes sense after learning that both films were filmed silent and all sound was added in post. One of the biggest concerns this causes is that neither film is in sync. On Oasis, the louder things got, the worse it sounded. Expect lots of harsh hissing and static. The only negative found during Lake was one scene where the film was completely out of focus with muffled sound. Clearly this can be chalked up to the source element seeing how both the picture and sound quality were affected at the same time.
The special features are extremely scant. Zombie Lake features more with an alternate English language version of the sexified opening credits; TV-edited versions of the opening sequence, and the volleyball splashdown where all the girls are now wearing panties, bras, or T-shirts; and English and French trailers for additional Rollin films including Zombie Lake, The Rape of the Vampire, Demoniacs, and Oasis of the Zombies. Oasis has even less featuring only trailers for itself, Zombie Lake, Female Vampire, and the double feature release of Exorcism/Demoniacs.
