You video is Rec.601 when you upscale it to HD I would convert it to Rec.709. At any rate, using Rec.709 as input is incorrect (as was already mentioned in the BM thread). Also, the primaries should be converted.

The quality is determined by the CRF option, all that faster processing will do is to make the compression less effective but that only translates into a slightly larger file.

QTGMC is way better than bob deinterlacing. Edited to add: poisondeathray made already clear he meant bob deinterlacing as part of QTGMC.
