Here's a comparison of how yadif, mcdeint and QTGMC handle detailed moving textures: parkjoy_deint_comparison.mkv

Pay attention to foliage, grass and the background. Yadif causes a lot of damage in those areas. Surprisingly the fence is also much better with mcdeint.

Notes
  • Speed is lowered to 5 fps for easier comparison. Speed up by a factor of ten for realtime playback (mplayer -speed 10).

  • Yadif looks better at realtime speed, but shimmers a lot. Mcdeint=0 leaves some combing artifacts to small moving objects. Mcdeint=2 seems to be slightly better in those areas, and at the spot where the fence appears at the right edge of the frame. QTGMC is very good overall, although one blurred branch that moves over the foreground at frames 215 to 250 (43 to 50 seconds) evaporates in the process.

  • File sizes (in kilobytes) of the 360x288 samples, encoded losslessly with x264 --qp 0 --preset fast:

    Code:
    yadif=1:     39156
    mcdeint=2:   35404
    mcdeint=0:   35108
    QTGMC:       31532
    
    interlaced:  19800
