It's an old VirtualDub plugin called Colortools by a Doom9 member called Trevlac. If you can't find it let me know and I'll send it you.

Regarding the advice above, I've since discovered that you can avoid clipping if you use VirtualDub's capture mode option to extend black/white points. Using this option, your captured YUY2 video includes "illegal" luma below 16 and above 235, with no hard cut off - and therefore is suitable for multi-pass averaging.

(The illegal pixels will of course get clipped if you convert to RGB, however to my surprise I found that CCE retains the full luma range - in YV12 - if you encode to MPEG2)
