To address the original question: oh yes there is most certainly a difference between different UV filters. You don't want to go sticking some cheap piece of coke-bottle glass in front of your lens; what's the point of buying a high-def camera if you're going to force it to look through some uncoated slab of cheap glass?
If you're going to put a UV filter in front of your lens, get the very, very, very, very best UV filter you can afford. EVERY SINGLE FRAME of video that you shoot from that moment on will be affected by that filter. You want a multi-coated filter for high light transmission and reduced reflection/glare. I went with a B+W 82mm MRC, cost something like $130 at B&H. If I could find a better one I'd probably get it.
B+W is the circular screw-in name for Schneider Optics; so Schneider and B+W filters are made by the same company. Heliopan is also a good brand. Hoya and Tiffen, at least in screw-in, are not as good from my experience.
