System and method for improving operational efficiency of a video encoding pipeline used to encode image data. In embodiments, the video encoding pipeline 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 determines a low resolution inter-frame prediction mode by performing a motion estimation search using the downscaled image data and previously downscaled image data. The video encoding pipeline also includes a main pipeline in parallel with the low resolution pipeline that includes a motion estimation block, which determines a candidate inter-frame prediction mode based at least in part on the low resolution inter-frame prediction mode, and a mode decision block, which determines a first rate-distortion cost associated with the candidate inter-frame prediction mode and determines prediction mode used to prediction encode the image data based at least in part on the first rate-distortion cost.
