Some points about taking video-
The more steady you can hold your camera, the more pleasing the resulting video will be. One way to accomplish this is holding your camera very steady. You need to be very conscious of framing your shot properly and keeping the camera steady. the much easier way is to use a tripod, or mount. Using a mount or tripod there is no camera shake and your results will look immeasurably better than if you try to hand hold the camera.
Obviously carrying a huge tripod around can be cumbersome and you all know my feelings on being able to keep your camera gear on you to be able to capture the shots as they happen. So many times a tripod is not going to be the answer.
The manfrotto modopocket which screws right into the universal camera mount and folds flush with the bottom of my camera is my number one camera accessory that I feel can help any photographer achieve much better results, especially with poor light (with good light photography is a snap, you just point and shoot and you don’t have to worry about camera shake because the time the lens will be open is so much shorter).
But for this application I used the kayalu nClamp with the toughbar extension. Literally I screwed the Kodak Playsport Zx3 onto the Toughbar and clamped it onto a bolt that was attached to the mast, framed the shot and pressed record. In this way I could sit back and enjoy the company on the boat and we got a nice video capturing the scene.
