What this node does

Deinterlace runs one of four ffmpeg deinterlacers on a COMFYTV_VIDEO clip to turn interlaced fields into full progressive frames, removing the horizontal “comb” tearing you see on motion in old TV/camcorder footage. It processes on ▶ Run and writes a new video snapshot. In and out are both COMFYTV_VIDEO. To interoperate with native ComfyUI nodes, insert a Bridge — see the bridge guide.

​
When to use it

  • Clean up old interlaced DV/DVD/broadcast footage before editing or upscaling.
  • Remove comb artifacts on motion that appear when interlaced material is shown progressively.
  • Prepare interlaced sources for frame interpolation or web export.

​
Parameters

​
method

Which deinterlacer to use. Options: bwdif (Bob Weaver, high quality, default), yadif (classic, fast), estdif (edge-slope estimation), w3fdif (weighted three-field). Default bwdif.

​
rate

Output cadence: frame (default) produces one progressive frame per input frame; field produces one frame per field, which doubles the output frame rate (smoother motion). Note estdif maps this to its own frame/field mode, w3fdif ignores it.

Tips

  • rate = field (and always w3fdif) doubles the frame count/rate — expect a longer render and a higher-fps result.
  • bwdif is the best all-round default; yadif is faster if you’re batch-processing a lot.
  • Frame Interpolate — smooth or slow the footage after deinterlacing.
  • Video Denoise — old interlaced sources are often grainy; clean up afterward.
