Abstract: Techniques are described to encode video content for mobile devices. A video content that is to be transmitted to a mobile device is received and different scenes are determined for the video content. For each scene that is found in the video content, one or more analysis techniques are performed on the scene. Based upon the results of the analysis techniques, the portion of the image to retain on each scene is determined. Finally, the video content containing the portion of the image on each scene to be retained is encoded based upon the type of the mobile device that will display the video content. The location and dimensions of each portion to be retained may vary from scene to scene, as these characteristics are determined on a per-scene basis.
