Abstract
A computer-implemented system and method are described for performing video compression. For example, a method according to one embodiment comprises: encoding a plurality of video frames or portions thereof according to a first encoding format, the first encoding format being optimized for transmission to a client device over a current communication channel; transmitting the plurality of encoded video frames or portions to the client device over the communication channel; concurrently encoding the first plurality of video frames according to a second encoding format, the second encoding format having a relatively higher-quality compressed video and/or a lower compression ratio than the first encoding format; storing the first plurality of video frames encoded in the second encoding format on a storage device; and making the first plurality of video frames encoded in the second encoding format available to the client device and other client devices for playback of the video stream.
