    Re: x264 Video Codec r1179 for chip x32 & x64

    20.07.2009

    latest changes:
    New AQ algorithm option
    "Auto-variance" uses log(var)^2 instead of log(var) and attempts to adapt strength per-frame.
    Generates significantly better SSIM; on by default with --tune ssim.
    Whether it generates visually better quality is still up for debate.
    Available as --aq-mode 2.

    Re: x264 Video Codec r1179 for chip x32 & x64

    x264 Video Codec r1247

    latest changes:
    - Change priority handling on some OSs
    - Instead of setting the lookahead thread to max priority, lower all the other threads' priorities instead.
    - This is particularly useful when the "max priority" is "realtime", as in Windows, which can cause some problems.
