Interpolating a Field in Interlaced Video

If you have a corrupt field in interlaced video captured from an analog source (such as VHS or Hi8), you may see flicker or snow when you play back the video. This effect can be caused by a dirty recording head.

Ideally, you may be able to resolve the situation by cleaning your heads and recapturing your video. However, if that isn’t an option, you can discard the corrupt field and interpolate it from the remaining field
