The main problem with how it looks on a computer screen is probably that your footage is interlaced rather than progressive scan. What that means is that video has two fields of information for every frame. The fields are displayed roughly every 60th of a second. The first field has half the lines of resolution, showing every other line of the picture, then the second field displays, showing the other half the resolution. These two fields are “Interlaced” to make one complete frame. TVs are designed to show video this way. Computer screens use Progressive Scan. That is, they display all the lines of a frame in order – no interlacing, no every other line field issue. But when you try to play interlaced video on a computer monitor, it results in that flicker and loss of resolution you are seeing. So to make things look better on a computer screen, you would want to encode your video as progressive, or use a “de-interlace” function. Unfortunately that sometimes results in a jerky look to the video when played on TV sets (unless they are a progressive scan display). Ain’t DVD fun?
