  54.             Images captured by videocards, especially when fast movement
  55.             is recorded, may look blurred and stripped, with splitted
  56.             objects. This is due to how cameras work. They don't record
  57.             25 images per second, but 50, with half vertical resolution.
  58.             There are two interlaced images in one frame. First line of
  59.             first image is followed by first line of second image
  60.             followed by second line of first image... etc. So, if there
  61.             have been an important move betwen the two images, objects
  62.             will appear splitted, shifted, stripped.
  63.           </p>
  64.         <p>
  65.             The Deinterlace filter keeps only one of both images and
  66.             replaces missing lines by a gradient between previous and
  67.             following lines. The resulting image, or selection, will be
  68.             somewhat blurred, but can be improved by enhance filters
