There is no point in vbitrate=15000000 and vpass=2 with vqscale=2.
vqscale is similar to "constant quality" encoding and any bitrate
settings are ignored, and only bitrate-based encodings profit from a
second pass.
Please suggest improvements to the documentation (esp. man page) if it
is unclear there.
