I have mainly used a video camera in the past when recording videos but\nrecently I used the video function on my Canon DSLR camera to record an\nevent at a beach.\n\nThere were two problems I encountered. The first was the camera suddenly\ngoing out of focus. If the subject is kept within the white square at the\ncenter of the lcd screen then its in focus but if you reposition the camera\nand the sky appears in the white square then the camera tries to focus on\nthe sky and ends up going out of focus. The limited field of view on DSLR\ncameras makes this more of a problem. The only way I can find to help\nreduce this problem is to pause the AF servo on the camera or have the\ncamera track an object. I tried manual focus but for some reason that was\ndifficult to do.\nThe other problem is that the DSLR camera seems picks a high shutter when\nrecording video so there are no natural blurs in the frames that you get\nwhen there is fast motion such as someone playing with hoops. Its possible\nto reduce the shutter speed when selecting Manual mode for the camera but\nthen you need to set the aperture and Set the ISO value or leave it in Auto\nmode. If you set the aperture too small (eg F16) then it stays fixed and\nwhen recording in darker part of the scene the iso value will increase\ncausing noise in the video.
