A processing system employs at least two graphics processing units (GPUs) to encode video. The GPUs employ sets of predicated values that indicate when reconstructed slices have been transferred between the GPUs. Furthermore, each GPU maintains a set of previous reference images, and encodes video slices based on the previous reference images having an expected predicated value. This allows each GPU to identify which reference images to use for encoding. This in turn allows the processing system to encode video frames without synchronization of the GPUs, while maintaining the quality of the encoded video.
