SYSTEMS AND METHODS FOR ENCODING VIDEO USING HIGHER RATE VIDEO SEQUENCES

Systems and methods for encoding video sequences using frames from a higher rate video sequence in accordance with embodiments of the invention are disclosed. One embodiment of the invention includes encoding frames in a first video sequence by selecting a frame in the first video sequence and selecting a frame in a second video sequence as a reference frame by comparing the similarity of the content of the selected frame from the first video sequence with the content of at least one frame in the second video sequence. The selected frame from the first sequence is then encoded using predictions that include references to the reference frame from the second sequence. Information identifying the reference frame from the second sequence is then associated with the encoded frame from the first sequence to enable decoding of the first sequence using the second sequence.
