Abstract
Techniques are described for learned bidirectional predicted frame (B-frame) coding. An example method can include receiving a residual associated with a frame of a current time step; determining first motion information for a first reference frame associated with a first time step and second motion information for a second reference frame associated with a second time step, wherein the current time step is after the first time step and before the second time step; determining third motion information for the frame based on the first motion information and second motion information; generating a predicted frame based on the third motion information, first reference frame and second reference frame; and generating, using the predicted frame and residual, a reconstructed B-frame for the current time step, the reconstructed B-frame representing the frame.
