I'm thinking of taking a 1080p video recorded from 5d mark ii and doing my project at 720. I'm thinking of trying anamorphic, and down sampling will give me more latitude. That and I'm stabilizing/ rolling shutter correcting some footage and I would rather down sample than zoom in. What is the difference in quality on a bluray player between 720 and 1080? Is this a bad idea, should I keep my deliverable in the highest resolution possible?
