Methods and systems for non-destructive, stabilization-based encoder optimization. A video item to be provided to one or more users of a platform is identified. An indication of a motion is identified between an initial video frame of a video sequence associated with the video item and a subsequent video frame of the video sequence. One or more motion stabilization transformations are applied to the video item to modify the motion between at least the initial frame and the subsequent frame. Upon applying the one or more motion stabilization transformations to the video item, the video item is encoded. The encoded video item and one or more instructions to cause the client device to reverse the one or more motion stabilization transformations applied to the video item after decoding the encoded video item are transmitted to a client device connected to the platform.

Provided are methods and apparatus for encoding and decoding motion information. The method of encoding motion information includes: obtaining a motion information candidate by using motion information of prediction units that are temporally or spatially related to a current prediction unit; adding, when the number of motion information included in the motion information candidate is smaller than a predetermined number n, alternative motion information to the motion information candidate so that the number of motion information included in the motion information candidate reaches the predetermined number n; determining motion information with respect to the current prediction unit from among the n motion information candidates; and encoding index information indicating the determined motion information as motion information of the current prediction unit.
