Table of Contents >> Disposing of Interlacing
In basic terms, a video can be thought of as being made up of numerous snapshots, called frames. A television, however, does not deal with video in terms of frames. Instead, it displays a video using half-frames, called fields. Each frame contains exactly two fields. One field is made up of the odd horizontal lines in a frame. This is called the odd field. The other field is made up of the even horizontal lines in a frame. This is called the even field.
However, when watching video on a television screen (interlaced display), the split isn't noticeable by human eyes. This is because, among other things, a television screen doesn't produce as crisp an image as does a computer monitor. Therefore, in only one of the four setups will the split be noticeable: interlaced video on a progressive display (monitor). This split in the image across fields due to motion is what is known as an interlacing artifact.
Mostly this effect appears in video that was captured from TV tuners or DV cameras. Our example illustrates the presence of interlacing:
To improve this video AVS Video Converter has a video effect which name indicates that it's exactly what we need - Deinterlacing. Considering, you've already started AVS Video Converter, opened the input file and clicked the Edit button - there are no difficulties, just do the following:
1. At the effects toolbar click the Add button. Then select Effect -> Deinterlace
2. You can remove interlacing artifact by removing one field of a video (the Even lines) and then blend (Interpolate) the remaining lines. Check the Even and/or Interpolate check-boxes, if needed.
Now, please take a look at the result:
