Abstract
Systems and methods disclosed herein create encoder sensitive video using single and/or bidirectional communication links between a video source and an encoding process to pass metadata (e.g., instructions and cues related to the video stream) to an encoder. A video system includes a video source to generate an uncompressed video stream and metadata corresponding to one or more characteristics of the uncompressed video stream. The video source may include, for example, a video camera or video editing equipment. The metadata may be based on a position, state, movement or other condition of the video source. The system also includes a codec communicatively coupled to the video source. The codec receives the uncompressed video stream and compresses it based on the one or more characteristics indicated in the metadata.
