# How do the H.264 encoding settings work in blender?

When encoding videos with H.264, I'm used to the constant rate factor compression setting. However I don't see anything like it in blender's options:

Is there a way to set the constant rate factor from the GUI? If not, what do these settings do? I can only assume they are for the two-pass method, but I'm not sure which ones correspond to the descriptions in the wiki.

Further down the page you refer to you, under additional information you will find ABR (Average Bit Rate) where you will find the -bitrate, -minrate, -maxrate and -bufsize that correspond to blender's settings.
