Title: COMPRESSED MEDIA WITH STILL IMAGES SELECTED FROM A VIDEO STREAM
Abstract:
A video hosting service receives and processes a source video to generate an efficiently compressed media file. The source video is transcoded to an intermediate video and corresponding audio. The video hosting service selects a subset of video frames from the intermediate video as still images and identifies the timing information associated with each selected still image. The selection process may be dependent on information associated with the video such as a video classification. The video hosting service encodes the selected still images and the audio data of the source video, and generates a compressed media file for transmission to a client device. The compressed media file does not include motion data associated with the selected still images to reduce the size of the compressed media file. A client device receives the compressed media file and plays the still images and associated audio data.
