Methods and systems for temporal distance based estimating of motion in multimedia picture encoding based on previously encoded predictive picture

A method comprising:

• receiving a plurality of pictures in a capture order;
• determining, by a motion estimation component, a temporal distance between a first picture of the plurality of pictures and a second picture of the plurality of pictures;
• in response to the temporal distance, determining, by the motion estimation component, a source picture;
• responsive to the temporal distance being less than a threshold distance value:
• determining, by the motion estimation component, a motion estimation parameter based on the source picture, wherein the motion estimation parameter includes a mean motion vector corresponding to one of a mean or an average of all motion vectors in one or more regions of interest of the source picture;
• and
• determining, by the motion estimation component, a motion parameter for a subsequent picture to the first picture in the plurality of pictures, wherein the motion parameter is based on the motion estimation parameter;
• responsive to the temporal distance being greater than the threshold distance value, determining, by the motion estimation component, the motion parameter for the subsequent picture to the first picture in the plurality of pictures based on a preselected motion estimation parameter, wherein the preselected motion estimation parameter is different from the determined motion estimation parameter;
• and
• encoding, by an entropy encoder component, the subsequent picture based on the motion parameter.
