Jim, I use a Sony HDR-XR520V HandyCam. The video, High Definition 1080 translates to a digital pixel use of 1920x1080 frame at 29 frames a second. You Tube cuts this down to 640x360 or below in Mpeg 4 format. This makes for very clear video on a big screen HDTV, but not so good streaming from YouTube. The camera can hold 240 GB of video & photos before having to download & can also take 12 meg photos & uses like my Canon binoculars a steady shot to smooth out the unsteady hands. I had over 6.5 hours of film & 600 photos stored on the camera by the end of the cruise. I never used a tripod & most video was shot while holding the camera in one hand & controlling the boat or Mokai with the other & trying to switch back & forth between photos & video.
The only major down side of the camera is its small lens which causes poor lighting & video clarity in some situations like cloudy days. Also in auto mode which I have to use being as I'm videoing on the go the lens will over darken even on a cloudy day when pointed in the direction of the small light that is available. In my opinion it was the best camera available in 2010 that could be used easily with one hand.
Don & Brenda, I'm happy to see your enjoying them.
