Deinterlace node


This documentation is for version 1.0 of Deinterlace (net.sf.openfx.Deinterlace).


Deinterlace input stream.

The following deinterlacing algorithms are supported:

  • Weave: This is what calls “do nothing”. Other names: “disabled” or “no deinterlacing”. Should be used for PsF content.
  • Blend: Blender (full resolution). Each line of the picture is created as the average of a line from the odd and a line from the even half-pictures. This ignores the fact that they are supposed to be displayed at different times.
  • Bob: Doubler. Display each half-picture like a full picture, by simply displaying each line twice. Preserves temporal resolution of interlaced video.
  • Discard: Only display one of the half-pictures, discard the other. Other name: “single field”. Both temporal and vertical spatial resolutions are halved. Can be used for slower computers or to give interlaced video movie-like look with characteristic judder.
  • Linear: Doubler. Bob with linear interpolation: instead of displaying each line twice, line 2 is created as the average of line 1 and 3, etc.
  • Mean: Blender (half resolution). Display a half-picture that is created as the average of the two original half-pictures.
  • Yadif: Interpolator (Yet Another DeInterlacing Filter) from MPlayer by Michael Niedermayer ( It checks pixels of previous, current and next frames to re-create the missed field by some local adaptive method (edge-directed interpolation) and uses spatial check to prevent most artifacts.

Parity / parity Choice Lower
Field to interpolate.
Lower (lower): Interpolate lower field.
