As mentioned before, Dr. Sapirstein's release, like some of his others, suffers from encoding problems and watermarks. If though his color correction is indeed accurate, his color correction would not be for naught despite the relative low quality of his video. Andrea's color match method could be used to transplant the corrected colors to a compression artifact-free source, without any frame re-syncing or cropping needed.
Incidentally, the original jump cut in the ending is preserved in HD in Terror in the Aisles on the Halloween II BD.
