Technical information on Xfire videos
Xfire captures video directly from the video buffer, the same way it takes screenshots and allows drawing of Xfire's in-game windows on top of the game graphics. For this reason video capture can only work on games where Xfire In-Game works otherwise.
Also, this restricts Xfire to only be able to record video from games. The normal Windows desktop is not drawn using the video card buffers directly, so Xfire's method cannot capture the normal screen space.
The video capture system is also used for video broadcasting. To read more about technical details of the broadcasting function, see Help:Broadcasting technical information. The rest of this article is mainly for the video capture feature that stores the captured video on the user's hard disk for further editing and/or uploading to Xfire's website.
To customize Xfire's video recording, see Help:Video capture options.
