Abstract The motion estimation which plays an important role in video coding requires much computation for encoding. In this paper, from the ray motion characteristics in the lenslet plenoptic video, we derive a new motion search model and propose a fast and efficient microlens-based motion search method. Theoretical analysis and experimental results have verified the new model and demonstrated its efficiency in search. Under the HEVC random-access configuration, we achieve not only substantial encoding time reduction (56.7%), but also bitrate saving of 1.3% on average compared to relevant existing works. Under the low delay configuration, the performances are 23.3% and 2.3%, respectively for encoding time reduction and bitrate saving.
