Wow. This video camera lark is a bit harder than I had imagined. The human eye is such a complex piece of equipment and with no thought at all our brains track objects near and far with ease.
As soon as you put a small screen at arms length, or nearer, the whole thing goes awry. Tracking the simple run of a dog becomes the hardest thing imaginable.
I uploaded a couple of test videos to You Tube. It was so much easier when I used the video recording tool on the little Sony compact camera. The Xacti is much better quality, it does 720 HD, but the technique of following the more random motion of the dog in the snow needs mastering.
Video 1 - Springer Spaniel
Video 2 - Ducks!
The second is marginally better as the camera was resting on the bridge support and this allowed it to be steadier.
