# SetFieldBased

std.SetFieldBased(vnode clip, int value)

  This is a convenience function. See SetFrameProps if you want to set other properties.

  SetFieldBased sets `_FieldBased` to value and deletes the `_Field` frame property. The possible values are:

  > 0 = Frame Based

  > 1 = Bottom Field First

  > 2 = Top Field First

  For example, if you have source material that’s progressive but has been encoded as interlaced you can set it to be treated as frame based (not interlaced) to improve resizing quality:

      clip = core.bs.VideoSource("rule6.mkv")
      clip = core.std.SetFieldBased(clip, 0)
      clip = clip.resize.Bilinear(clip, width=320, height=240)
