I just notice (or re-discover) a pattern that QTGMC() fails but TGMC() works.

Pick a true intelaced footage (say, NTSC) that has a solid black 1-pixel line at row 478 on every frame. After bobbing, QTGMC() will have the black removed on even frames, and a 2-pixel-high black line on odd frames. TGMC() keeps the 1-pixel black line on every frame.
