Syntax: x264 [options] -o outfile infile

Infile can be raw (in which case resolution is required),
  or YUV4MPEG (*.y4m),
  or Avisynth if compiled with support (yes).
  or libav* formats if compiled with lavf support (yes) or ffms support (yes).
Outfile type is selected by filename:
 .264 -> Raw bytestream
 .mkv -> Matroska
 .flv -> Flash Video
 .mp4 -> MP4 if compiled with GPAC or L-SMASH support (lsmash)
 .3gp -> MP4 (branded '3gp6')
 .3g2 -> MP4 (branded '3gp6' and '3g2a')
 .mov or .qt -> QuickTime File Format
 .avi -> AVI if compiled with support (yes)
Output bit depth: 8/10
.

Example usage:

      Constant quality mode:
            x264 --crf 24 -o <output> <input>

      Two-pass with a bitrate of 1000kbps:
            x264 --pass 1 --bitrate 1000 -o <output> <input>
            x264 --pass 2 --bitrate 1000 -o <output> <input>

      Lossless:
            x264 --qp 0 -o <output> <input>

      Maximum PSNR at the cost of speed and visual quality:
            x264 --preset placebo --tune psnr -o <output> <input>

      Constant bitrate at 1000kbps with a 2 second-buffer:
            x264 --vbv-bufsize 2000 --bitrate 1000 -o <output> <input>

      crop:left,top,right,bottom
            removes pixels from the edges of the frame
      pad:[left][,top][,right][,bottom][,width][,height][,red][,green][,blue]
            adds pixels to the frame edge
            default values for red, green and blue are 0
      resize:[width,height][,sar][,fittobox][,csp][,method]
            resizes frames based on the given criteria:
            - resolution only: resizes and adapts sar to avoid stretching
            - sar only: sets the sar and resizes to avoid stretching
            - resolution and sar: resizes to given resolution and sets the sar
            - fittobox: resizes the video based on the desired constraints
               - width, height, both
            - fittobox and sar: same as above except with specified sar
            - csp: convert to the given csp. syntax: [name][:depth]
               - valid csp names [keep current]: i400, i420, yv12, nv12, nv21, i422, yv16, nv16, yuyv, uyvy, i444, yv24, bgr, bgra, rgb
               - depth: 8 or 16 bits per pixel [keep current]
            note: not all depths are supported by all csps.
            - method: use resizer method ["bicubic"]
               - fastbilinear, bilinear, bicubic, experimental, point,
               - area, bicublin, gauss, sinc, lanczos, spline
      select_every:step,offset1[,...]
            apply a selection pattern to input frames
            step: the number of frames in the pattern
            offsets: the offset into the step to select a frame
            see: http://avisynth.nl/index.php/Select#SelectEvery
      vflip  vertically flips the frame
      yadif:[mode][,order]
            Deinterlaces the picture using MPlayer's yadif
            mode: sets the deinterlacing mode
            0 - single-rate deinterlacing (default)
            1 - double-rate deinterlacing (bob)
            2 - single-rate deinterlacing without spacial interlacing check
            3 - double-rate deinterlacing without spacial interlacing check
            order: forces the field order
            tff - top-field first
            bff - bottom-field first
      subtitles:
            renders subtitles using VSFilter
            need VSFilter.dll

      --sub <string>          Load subtitles file (used with video filter "subtitles")
                              can be called more than once to load multiple subtitles
