The **GOP (Group of Pictures) size** (``-g:v``) is the max interval between
keyframes. Increasing this value can improve compression with almost no impact
on quality. The valid range goes from ``0`` to ``2,147,483,648``, although
compression benefits will fade away and even be reversed as the GOP size
increases. The default size (``12``) is too low for most types of content, it's
therefore recommended to test higher GOP sizes before reducing video quality.
