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 support (yes)
Output bit depth: 8 (configured at compile time)

Options:

-h, --help List basic options
--longhelp List more options
--fullhelp List all options

Example usage:

Constant quality mode:
x264 --crf 24 -o

Two-pass with a bitrate of 1000kbps:
x264 --pass 1 --bitrate 1000 -o
x264 --pass 2 --bitrate 1000 -o

Lossless:
x264 --qp 0 -o

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

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

Presets:

--profile Force the limits of an H.264 profile
Overrides all settings.
- baseline,main,high,high10,high422,high444
--preset Use a preset to select encoding settings [medium]
Overridden by user settings.
- ultrafast,superfast,veryfast,faster,fast
- medium,slow,slower,veryslow,placebo
--tune Tune the settings for a particular type of source
or situation
Overridden by user settings.
Multiple tunings are separated by commas.
Only one psy tuning can be used at a time.
- psy tunings: film,animation,grain,
stillimage,psnr,ssim
- other tunings: fastdecode,zerolatency

Frame-type options:

-I, --keyint Maximum GOP size [250]
--tff Enable interlaced mode (top field first)
--bff Enable interlaced mode (bottom field first)
--pulldown Use soft pulldown to change frame rate
- none, 22, 32, 64, double, triple, euro (requires cfr input)

Ratecontrol:

-B, --bitrate Set bitrate (kbit/s)
--crf Quality-based VBR (0-51) [23.0]
--vbv-maxrate Max local bitrate (kbit/s) [0]
--vbv-bufsize Set size of the VBV buffer (kbit) [0]
-p, --pass Enable multipass ratecontrol
- 1: First pass, creates stats file
- 2: Last pass, does not overwrite stats file

Input/Output:

-o, --output Specify output file
--sar width:height Specify Sample Aspect Ratio
--fps Specify framerate
--seek First frame to encode
--frames Maximum number of frames to encode
