The Deinterlace filter removes interlace effect in the movie.

Many digital camcorders divide each frame into a set of even and odd horizontal raws: even raws are recorded first, and then the odd raws. So, each frame you see consists of two consecutive pictures. This mixture is called interlacing. It allows compressing video without using digital compression methods.

But if you record a fast moving object (sport competition, racing, pets, children and so on), it can be at one place in the "even" picture, and at another in the "odd" one. As a result, you get a "striped" picture. The Deinterlace filter transforms the mixed frames into normal video frames and removes the interlaced horizontal raws.
