BTW, speaking of temporal and spatial deinterlacing: AFAICT one means combining fields to provide maximum resolution with half the frame rate of the interlaced fields, and the other maximises the frame rate while discarding resolution; but which is which? And does NVidia's temporal
spatial try to give the best of both worlds through some sort of interpolation?
Temporal = motion adaptive deinterlacing at either half or full field rate. Some programs refer to the latter by "2x". "Motion adaptive" means that the filter detects interlaced parts of each frame and adjusts deinterlacing accordingly. This gives better quality at stationary parts.
Temporal-spatial = Temporal with edge-directed interpolation to smooth jagged edges of moving objects.
Both methods give about the same spatial and temporal resolution but temporal-spatial will look nicer.
I still can't translate that explanation into simple mechanics. Is temporal like weave and spatial like bob or the other way round? Or something a little more sophisticated, interpolating parts of the picture belonging to the "wrong" field from previous and/or next frames?
