a. 2 pass, first pass:
a1) Quantizer: 0 is highest quality? I want to encode 1/3 DVD.

0 is highest quality (similar bitrate to huffyuv, though it depends on the amount of motion). I find h264 @ qp=18 to be similar to mpeg4asp @ qp=2, and h264 @ qp=24 to be similar to mpeg4asp @ qp=4.

a3) Number of reference frames: 3 -5 ?

more is always slightly better, but if you care at all about speed, 3-5 is good.
Quote:
a4) Number of b-frames: 2-3 would be
|
No. We don't have adaptive B-frames yet, so don't use more than 1.
Quote:
a5) I want to use somethimg like adaptive. Is -2 for both ok?
|
is this deblocking? yes, -2 is ok.

a7) subpixel refinements: Always QPel brings highest quality?
|
Always QPel is the highest quality, but is only needed on the final encode. For the 1st pass you can set it to medium with negligible loss.
Quote:
a8) Macroblock options: Both for highest quality? b8*8mv and 4*4mv?
|
yes.

b. 2 pass, second pass
Bitrate: Bitrate for a 1/3 DVD Rip? From a calculation tool?
|
You can set bitrate to whatever you want. That part of encoding hasn't suddenly changed with h264.

3) Quant & RC
Buffer Size = Bitrate and I should activate "fix" ?

Don't touch buffer size unless you know what you're doing.
