You can specify codec specific encoding parameters using the following syntax:
-<codec>opts <option1[=value],option2,...>
Where <codec> may be: lavc, xvidenc, divx4, lame, toolame, twolame, nuv, xvfw, faac, x264enc, mpeg, lavf.
Encoding with Video for Windows codecs is mostly obsolete unless you wish to encode to some obscure fringe codec.
codec=<name>
The name of the binary codec file with which to encode.
compdata=<file>
The name of the codec settings file (like firstpass.mcf) created by vfw2menc.
