I can also add another very common type used in DVDs - Progressive content placed inside Interlaced container. This is usually used for 25fps PAL videos.
Container auto detected as interlaced, but if change input type to Progressive video will look like 25fps progressive.
If Change to input interlaced and set QTGMC tff or bff - it will show normal 25 fps framerate. QTGMC will act like noise reduction here. This may slightly improve quality, but same time also may add new strange artifacts.
Changing between tff or bff usually makes no any difference here because frames are almost the same, but you can experiment and look which version visually look best for you. Same problem - QTGMC may add new strange motion artifacts
If Change to QTGMC bob - it will output 50fps but show two almost identical repeated progressive frames instead of one.
Another probably better way to deal with this footage - instead of QTGMC, set input type to Progressive and use Line -> AntiAliasing -> DAA or DAAmod or Nedi3AA or Santiag filters before Resizer to remove those tiny jagged/interlaced artifacts.
Frame -> Misc -> Vinverse filter also may help to fix random interlaced combed artifacts, but it also may affect image quality a little.
