If you haven't already installed Darwin Ports, you can find easy instructions for doing so at the main Darwin Ports page.
Once Darwin Ports has been installed, in a terminal window and while online, type the following and hit return:

%  cd /opt/local/bin/portslocation/dports/x264
%  sudo port install x264  
Password: 

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching x264
--->  Verifying checksum for x264
--->  Extracting x264
--->  Configuring x264
--->  Building x264 with target all

--->  Staging x264 into destroot

--->  Installing x264

- Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using x264 with these commands:

%  man x264
%  apropos x264
%  which x264
%  locate x264
