Jan van der Meer explains how to stop jerky motion with his new Sanyo Xacti HD2000 in Full HD 1920x1080 60 FIELD mode. Some people hate this camcorder for that reason and that is such a pity, because this is absolutely one of the best FULL HD camcorders for this price available now. BUT this tip counts for nearly all camcorders. In sunny conditions AE (Automatic Exposure) often results in a unnatural jitter and jerky motion effects. (Even seen in many Canon 5D clips) When exposure reaches its maximum level (F11 or a bit higher), increasing shutterspeed is automaticly used to bring exposure level down. But this results in unnatural jerky motion! So if you want to eliminate this, use a Grey filter (ND4) or Linear Polarfilter in combination with a manuel shutterspeed of 1/50 or 1/60 up to maximum 1/100 or 1/125 in very sunny conditions.
