So I bought a HF200 a while back and everytime I've shot snowboarding (pretty much all this camera is used for) my footage is blurry and has artifacts. Basically looks horrible. I shoot in 60i and even if i use a high shutter speed 1/250 I still seem to have the same problem. On the editing side I usually compress it to HDV 720 or H.246 720 so that my computer can handle it. Here is an edit I made where you can see my problem, hopefully someone can help.
