Abstract
Systems and methods for editing and selectively encoding video. In general, in one implementation, the method includes generating video segments from portions of one or more video sources, at least one video source being encoded to have interframe dependencies; generating a video sequence from the video segments; scanning the generated video sequence to identify invalid interframe dependencies; and selectively reencoding portions of the generated video sequence to generate an output video sequence having valid interframe dependencies. The method may further comprise generating the output video sequence without reencoding valid portions of the video sequence. Valid portions of the video sequence may comprise portions lacking invalid interframe dependencies or buffer violations.
