The speed and visual quality of AR Toolkit applications is often restricted by a system's CPU, video capture card, or 3D acceleration hardware. Many AR toolkit users find that they must limit video resolution to 320×240. Furthermore, complex 3D geometry, textures, and animations can lower video frame rates forcing users to reduce the quality of their content. In broadcast and feature film production, chroma key techniques are used to composite real time 2D and 3D graphics with live scenes. This technique can be used in conjunction with the AR Toolkit to improve an application's 3D rendering and video capture performance.
