There are 2 methods for recording with Automatic and Manual. You can choose which one you want to use in the Preferences under "Video"

Automatic will begin recording right when you start the game (and for some games, when you start a match).

When selected, you can also choose a hotkey for placing a Bookmark, as well as the length of it. 

Bookmarks allow you to keep track of awesome moments that could be difficult to find in hours of footage.

If you decide to use Manual Recording, you'll have the choice of setting a hotkey to stop/start recording. You also have access to the Highlight function where it can quickly grab the last set amount of time and save it separately. You get to choose which button saves a Highlight, and how long you want that Highlight to be.

If you want to change the quality of your recordings, scroll down til you get to "Quality Presets".

You can use our recommended settings, or adjust the quality for yourself.

Video Resolution: 480p, 720p or 1080p

Framerate: 15, 30, or 60 FPS
