Abstract: A video capture utility and method for a computer system. In one embodiment, the video capture utility includes: (1) a circular buffer allocated in a memory of the computer system to store at most a predefined video length, (2) a video output interceptor executable in a processor of the computer system and operable to receive and store video output most recently generated by an application program and (3) a video output extractor executable in the processor and operable to prompt contents of the circular buffer to be copied from the circular buffer to another location.

Abstract: A system and method are provided for a 3D modeling system with which an encoded video stream is produced. The system includes a content engine, an encoder, and a fixed function engine. The fixed function engine receives content information from the content engine. The fixed function engine produces encoder information from the content information. The encoder uses the encoder information to produce an encoded video stream having at least one of a higher quality and a lower bandwidth than a video stream encoded without the encoder information.
