    Here's the description I'll add to the mplayer man page:
    ---
    Causes frames with higher quantizers to be more likely to trigger a
    scene change detection and make libavcodec use an I-frame (default: 1).
    1-16 is a sane range.
    Values between 2 and 6 may yield increasing PSNR (up to approximately
    0.04 dB) and better placement of I-frames in high-motion scenes.
    Higher values than 6 may give very slightly better PSNR (approximately
    0.01 dB more than sc_factor=6), but noticably worse visual quality.

    Original idea from Michael; patch by me.
