What is the "2.5 functionality" that is commented in that post?

Version 2.5 of Avisynth (currently in alpha stage) has numerous enhancements, most notably the inclusion of support for YV12. YV12 is a colourspace like RGB or YUY2 (most similar to the latter), and is the format DVDs and VCDs are actually encoded in.

With modified YV12-compatible versions of VirtualDub and XViD it's possible -- if all filters in the script support YV12 -- to obtain a 25-30% performance boost over YUY2 mode. There's great excitement over at the XViD forum ;).

(Incidentally, the benefit for TMPGEnc users will be smaller because TMPGEnc requires RGB input which it then internally converts to YV12. This means that even if the entire Avisynth script were operating in YV12 mode, we'd still require a ConvertToRGB() at the end of it. Nothing can be done about this except bugging the TMPGEnc authors to accept YV12 input.)
