Hello:
In my mind there is no substitute for a Camera Rig that can take photos using SD cards, and mine in a Sony HDC-400, and it can take Video as well. What I do is to set a tripod up if I am gonna be in FRONT of the camera recording vids, and if behind it, I have to hold it still when shooting, or it can Blur up like crazy. Most of the time, I have to manage the FLASH, depending on the location I use it: if its too DARK, open your flash, if too light, you may want to close the flash. You also would want to make sure that your camera is set for the quality that you want, and the settings are correct for the TYPE of shot you are taking: I am no expert, but have learned that the settings and way you use your camera DO make a difference ?
Good Luck
Brian
