Getting high resolution images from interlaced HD video

Images from videostreams

Modern digital cameras can record video at high resolution, 1920x1080, which is equivalent to the resolution of to the largest main stream monitors. Thus, if you want to view the image on a computer screen (or a television monitor), this resolution is what you want, larger images would need to be scaled down to fit the screen, and smaller images would have to be scaled up to fill the screen.

However, videostreams are often interlaced, and must therefore be deinterlaced in order to - in image form - precisely render the motive of the recording.

The workflow is this:

  1. Load the videostream into avidemux
  2. Save the frame of interest as a bmp image.
  3. Deinterlace the image in an image-processing program like gimp.

I tried to apply the motion compensating deinterlacer built into mplayer, but the results were worse than a simple deinterlacing with gimp.
