Abstract
Various embodiments of an automated adaptive bitrate (“ABR”) encoding system and method that encodes an input video into a set of encoded video streams for ABR delivery, also known as an ABR ladder. The automated ABR encoding system encodes the input video into an initial number of speculative encodings, based on respectively determined resolution and quality level settings for the individual speculative encodings. It then estimates quality scores for a plurality of potential output encodings based on respective output statistics of the speculative encodings. It selects a plurality of better quality output encodings from the plurality of potential output encodings based on the quality scores. It then encodes the input video a second time into the plurality of better quality output encodings. The automated ABR encoding system selects one or more output encodings from the plurality of better quality output encodings to include in the ABR ladder.
