I have a zombie mocumentary that I'm toying with the idea of. I'm considering shooting it in SD to make the creature effects more believable on a lower budget. Since I would be fronting the cost for this because it's just an idea that I want to do, I will likely be using student or beginning make up artists. My thinking is that SD will provide a margin of error for the effects. The finished product will be 22 minutes in the style of "reality" TV shows. I have numerous cameras of both SD and HD resolution. In fact, I have more HD cameras than SD cameras at this point, so I could get more coverage using HD, but I think that the HD would show any flaws in the makeup to a greater extent. This would just be a YT/Vimeo project with possible, but unlikely, festival submission.
