all you do is create a bat file, in your favorite text editor. Save it as .bat. Bat files are executable, so all you have to do is double click and it will run the commands within it in a DOS window for you. You can either goto Start> Run > Type : cmd , and then type the commands by hand, or make a couple of bat files to do it all for you. Simply enough, place the first set of codes to execute X264.exe in one bat file:
@echo off
start /belownormal /b /w x264 -p 1 --stats %3 -o nul: --progress %1
start /belownormal /b /w x264 -B %4 -p 2 --stats %3 -o %2 --progress %1
Save this as x264.bat
Then create another bat file, with the second set of code:
@echo off
start x264.bat AVS_Name.avs Output_Name.mp4 Stats_Log.log 1000
Bitrate is the last value and is set in Kbps. Save this as encode.bat
Then all you need to do is run encode.bat ( by double clicking it) and it will execute X264 with the commands from x264.bat.
The available commands to X264 can be gotten from running the -h flag... but here:
x264 core:23 svn-215M
Syntax: x264 [options] -o outfile infile [widthxheight]
Infile can be raw YUV 4:2:0 (in which case resolution is required),
or AVI or Avisynth if compiled with AVIS support (yes).
Outfile type is selected by filename:
.264 -> Raw bytestream
.mp4 -> MP4 if compiled with GPAC support (yes)

-p, --pass <1|2|3> Enable multipass ratecontrol:
- 1: First pass, creates stats file
- 2: Last pass, does not overwrite stats file
- 3: Nth pass, overwrites stats file
--stats <string> Filename for 2 pass stats ["x264_2pass.log"]
--rceq <string> Ratecontrol equation ["blurCplx^(1-qComp)"]
--qcomp <float> QP curve compression: 0.0 => CBR, 1.0 => CQP [0.60]
--cplxblur <float> Reduce fluctuations in QP (before curve compression) [20.0]
--qblur <float> Reduce fluctuations in QP (after curve compression) [0.5]
-A, --analyse <string> Analyse options: ["i4x4,p8x8,b8x8"]
- i4x4
- p8x8, p4x4, b8x8
- none, all
--direct <string> Direct MV prediction mode ["temporal"]
- none, spatial, temporal
-w, --weightb Weighted prediction for B-frames
--me <string> Integer pixel motion estimation method ["hex"]
- dia: diamond search, radius 1 (fast)
- hex: hexagonal search, radius 2
- esa: exhaustive search algorithm (slow)
--merange <integer> Maximum motion vector search range [16]
-m, --subme <integer> Subpixel motion estimation quality: 1=fast, 5=best. [5]
--no-chroma-me Ignore chroma in motion estimation
--level <integer> Specify level (as defined by Annex A)
--sar width:height Specify Sample Aspect Ratio
--fps <float|rational> Specify framerate
--frames <integer> Maximum number of frames to encode
-o, --output Specify output file
--no-asm Disable all CPU optimizations
--no-psnr Disable PSNR computation
--quiet Quiet Mode
-v, --verbose Print stats for each frame
--progress Show a progress indicator while encoding
--aud Use access unit delimiters
You then just add these flags (things with - or -- by them) along with their associated value by adding/changing them in the first bat file, x264.bat. An example would be close to:
start /belownormal /b /w x264 -I 300 -i 30 -b 2 -B %4 -w --b-pyramid -p 2 --stats %3 -o %2 --progress
If you are this scared about using the command line, then I suggest you use the VFW version via VirtualDub or something. This CLI version is a bit more advanced... but is not too complicated once you work with it.
