Don't use CBR unless you really need constant bitrate.
2 pass (with first pass at constant quantizer) is much better. But don't ask me when the next ffdshow binary release will be.

I know 2pass is better, and that VBR is better. It's just *not* avalible yet. :)

ffdshow´s developers promised 2 pass, didn´t they?

Supposed to. x264 has the potential to compete against commercial H264.

Most of the codecs in ffdshow are part of libavcodec, and share the same ratecontrol code. They can either use libavcodec's own ratecontrol, or ffdshow's implementation of XviD's ratecontrol.
However, x264 is a separate library. It is included in the same ffdshow interface, but doesn't share code with libavcodec. So it needs to be explicitly supported.
And it looks like there is a new build of ffdshow as of yesterday, though I can't vouch for its contents as it doesn't run under Wine.

i have not noticed any changes since the last build. also no 2-pass for x264.
