@ tateu:
fascinating. looks like QT/blackmagic has a dirty little secret? that chroma drift looks to have been created by multiple yuy2-rgb conversions (and it drifts to the side! that means even with 1 generation there's going to be a chroma offset... i mean come on, is it that hard to convert colourspaces without moving stuff around?) that's good though - that means us avisynthers can make as many generations as we like without loss. though i fear for 10-bit files the same losses will occur (it'd be cool to dither 10-bit to 8-bit on import, but that's for another time. and when avs 3.0 comes along it'd be much nicer to just use it's 15 bit colourspace on 10 bit files). looks like i'll be doing all my capping in 8 bit for now then thanks heaps for your import plugin - it's nice to know there's more quality to be had from quicktime than what quicktime itself actually provides.
