Subjective visual comparisons of footage-in-the-wild using various encoder deinterlacers are fraught with variables -- perhaps the two biggest being the observer and the viewing screen. In addition, it has proven difficult to find real-world footage containing sustained sharp oblique or radial motion, which are the truest test of decombing as compared to deinterlacing, the latter being at its best with lateral subject and camera movement. Stringer's enduring "Driving Along" clip is a good example of this.
For that reason, I set out to contrive a synthetic deinterlacing benchmark, and it has turned out to be a lot of fun. The idea of a whirling Lissajous was borne of Glenmorangie, and not anything more sinister.

Usage and Viewing Environment:
-- Comparisons are valid only at 1920x1080 30p resolution at 1:1 Scaling.
-- Edge Inspection: Freeze or Grab a frame, magnify, and compare with other solutions. You will see some marked differences.

-- Temporal (Time / Motion) Testing -- This is where you unpause, let it loop, stand back for a while, and form your own impressions. You will find straightaway that every playback environment will look different with every deinterlacer, so your decisions with regard to smoothness vs. sharpness will mostly rely on the screen environment you most often watch..
-- Next, of course, come the subjective decisions based on the way you want to see your own video. It's also good to ask the opinions of others.
