RE:Vision’s FieldsKit ReInterlacer

Friday, May 16th, 2014

In Summary:

Purpose of FieldsKit ReInterlacer:

  • Transforms progressive video (e.g. HDp25 frames/sec) into spatio-temporal interlaced video (e.g. SDi50 fields/sec).  It achieves this by estimating the fields that would have been shot (had the original video itself been shot as interlaced) between each frame of the progressive video, via a process of motion estimation.
    •  Most NLEs do not use this “perfectionist” method, instead they at best simply combine (ghost-blur) successive frames, with no compensation for time/motion.
    • On an interlaced display, such as an old analog TV or projector,
      • The “NLE-simple” approach may lead to dynamic (changing e.g. moving) scenes and objects appearing flickery.
      • The “perfectionist” approach will instead typically avoid such flicker.

Configuration of  FieldsKit ReInterlacer:

  • Field Order: [Lower First]
  • Output Type: [= Create motion estimated fields]
    • This is not the default (oddly).  But it is the only proper way to get the expected “perfectionist” reinterlacing to happen!
  • Source Layer: [Video 1]
