MPEG > Modulation > H.232 ?

Modulated isn't a quantization for itself. It's only a method that Koepi came up with that chooses between H.263 and MEPG quantization, depending on the quantizer used for that particular frame.

Someone please correct me if i am wrong.

You're right, it's no "level of it's own".

But it _can_ be sharper as pure .h263 quant type, if the quantizer range allow some frames with quantizer < 4.

Would MPEG 1st pass + MPEG 2nd pass results in all ALL MPEG final frames?

Basically, what would be the final results of the following combinations:

(1st pass) (2nd pass)
MPEG + MPEG
MPEG + H.xxx
H.xxx + Mpeg
Mod + Mpeg

Mpeg + Mod
Mod + Mpeg
Mod + H.xxx
H.xxx + Mod

Mod + Mod

If I want maximum sharpness should I choose MPEG for BOTH passes then?

Read the XOE.

and then again.
and then once more.

And then, if you still dare, ask that question with those combinations and that "result" again...
