The encoder defaults to mode 1... which is 1-pass VBR with a quantizier setting of 8. You only need to supply the input and output files and these switches
-framerate <xxxx> -profiletype <x> -bframes <x> -maxkeydist <x>

VC-1 AVS2ASF v0.4 Encoding Sample
Original Sample AVI2ASF code Copyright (C) Microsoft Corporation.
All rights reserved.
Avisynth, YV12 & Raw support added by Nic.
Aspect Ratio, Help and Rate Control Mode changes by Northpole.
*************************************
The required parameters are based on the default rate control mode 1,
1-pass VBR with a Fixed QP of 8.
If you change the rate control mode, simply specify appropriate values
for the required parameters.
Syntax:
AVS2ASF.exe -i <inputfile> -o <outputfile>
-framerate <frame rate> -profiletype <profile type>
-bframes <number of b frames> -maxkeydist <maximum key frame distance>
[Optional 1] <value1> [Optional 2] <value2> ...
Command line options:
-i <input AVI file name>
-o <output ASF file name>
[-rate] <output rate (kilobits per second)>
The range is 1 to 135000.
Not used when Rate Control Mode equals 1.
[-complexity] <encoder complexity>
0 to 5, 0 = best performance, 5 = best quality.
[-qp] <quantization parameter (QP)>
Fixed QP if -ratecontrol equals 1 (1-pass VBR)
Max QP if -ratecontrol equals 0 or 2 (CBR)
The range is 1 to 31.
Not applicable when Rate Control Mode equals 3 or 4.
[-framerate] <source frame rate>
[-interlaced] Specifies interlaced source.
[-maxkeydist] <maximum distance between key frames>
[-bframes] <number of B-frames per P-frame>
Range is 0 to 7.
[-peakrate] <peak bit rate (kilobits per second)>
The range is 1 to 135000.
Not used when Rate Control Mode equals 0, 1, 2, or 4.
[-profiletype] <type specifier>
0 = Simple, 1= Main, 2 = Advanced.
[-ratecontrol]
0 = 1-pass CBR
1 = 1-pass VBR fixed QP
2 = 2-pass CBR
3 = 2-pass peak constrained VBR
4 = 2-pass unconstrained VBR.
[-vbv] <size of vbv buffer>
The range is 1 to 157696 for Simple profile, 1 to 5001216 for Main profile
and 1 to 33792000 for Advanced profile.
VBVBuffer = Bit rate in kbps x buffer duration in seconds x 125.
Recommended buffer duration = 8 seconds.
Not used when Rate Control Mode equals 1 or 4.
[-colorformatflags] <colorformatflag> <colorprimaries> <transferchar>
<matrixcoef>
- If colorformatflag is 1, then you must specify colorprimaries,
transferchar, and matrixcoef.
- If colorformatflag is 0, then no need to specify colorprimaries,
transferchar, and matrixcoef because the decoder will generate them
for you.
[-denoise] <0 or 1>
Turn on or off denoise filter.
[-inloop] <0 or 1>
Turn on or off in-loop filter.
[-median] <0 or 1>
Turn on or off median filter.
[-overlap] <0 or 1>
Turn on or off overlap smoothing.
[-noiseedge] <0 or 1>
Turn on or off noise edge removal.
[-deltamvrange] <delta mv range index>
0 = off, 1= horizontal, 2= vertical, 3 = h + v.
[-motionsearchlevel] <level>
0 = Luma only. (Default)
1 = Luma w/ nearest-int chroma.
2 = Luma w/ true chroma.
3 = Macroblock-adaptive with true chroma.
4 = Macroblock adaptive with nearest int chroma.
[-mesearchmethod] <phase>
0 = off, 1 = always use hadamard, 2 = adaptive sad/hadamard
[-mbcost] <cost method>
0 = SAD/Hadamard, 1 = RD cost.
[-mvcost] <cost method>
