It's not the 5x capturing it's the edge directed 2x resizer that takes away a little of the sharpness which is why I added 2 sharpening filters into my conversion to compensate, I've stuck with the edge directed resizer because it also reduces some of the grain, the sharpness on Moth3r's version is an illusion helped by the haloing, if you were to take away the haloing the perceived sharpness would decrease.

Both the PAL & NTSC versions of my trilogy come from the same 'master' capture files so look virtually identical in terms of colour/detail etc., I didn't encode one format then convert to the other.
