Abstract: A method for encoding video for communication over a network includes receiving, at a first video encoder, video data that defines frames, generating; by the first video encoder, motion vectors that characterize motion between frames of the video data; and communicating, by the first video encoder, the video data and metadata that defines at least the motion vectors to a second video encoder. The method also includes generating, by the second video encoder, refined motion vectors based on the video data and the motion vectors communicated from the first video encoder; and encoding, by the second video encoder, the video data based on the refined motion vectors.
