Abstract: Techniques are described for dynamically restructuring an encoded video stream to support a wide range of high-speed playback with accompanying visual feedback of the underlying video content. For a particular range of playback speeds, frames in each fragment are retained or dropped based on the encoded dependencies among the frames in the fragment and the selected playback speed. The set of frames in each fragment is analyzed to determine the optimal pattern of frames to retain or drop for a given playback speed. The time stamps of the retained frames are adjusted to achieve the proper spacing for the decoder.

Abstract: A user can select an object represented in video content in order to set a magnification level with respect to that object. A portion of the video frames containing a representation of the object is selected to maintain a presentation size of the representation corresponding to the magnification level. The selection provides for a “smart zoom” feature enabling an object of interest, such as a face of an actor, to be used in selecting an appropriate portion of each frame to magnify, such that the magnification results in a portion of the frame being selected that includes the one or more objects of interest to the user. Pre-generated tracking data can be provided for some objects, which can enable a user to select an object and then have predetermined portion selections and magnifications applied that can provide for a smoother user experience than for dynamically-determined data.

Abstract: Technology is described for identifying a scene in video content. Video content to be played on a device may be provided. A segment of the video content that includes an occurrence of an interest event may be identified. A scene may be created with the segment based on a starting time code of the segment. The scene with the segment may be provided for playback.
