If I were you I would use a camera that can shoot in 24p. Or if that's not possible, shot 30p. I did that on my short film and put it on youtube and it looks fine; you will always lose quality when going to something like youtube because of the compression, but youtube as far as i'm concerned can handle 24p stuff.
Also remember; good lighting, composition, camera movement, and acting will also sell the "cinematic look."
