Abstract
Systems and methods for improving operational efficiency of a video encoding system used to encode image data are provided. In embodiments, the video encoding system includes a low resolution pipeline that includes a low resolution motion estimation block, which generates downscaled image data by reducing resolution of the image data and performs a motion estimation search using the downscaled image data and previously downscaled image data. The video encoding system also includes a main encoding pipeline in parallel with the low resolution pipeline that includes a motion estimation block, which determines a global motion vector based on data from the low resolution motion estimation block. The main encoding pipeline may utilize the global motion vector in determining a candidate inter prediction mode.
