I am new to this forum. Infact very new. I have a strange problem and need some help in this. I have a Sony digicam which is about 5 yrs old. It uses casettes to record the video. When I capture the video with a video editing software artifacts appears in the captured video. They are like block pixels all over the video and it is very difficult to watch or edit. But if I directly connect my digicam to the TV and watch it, the video is crystal clear. Can anyone please tell me how to remove these blocks so that the video appears clear. Please help me.
