Claim 5:
6. A method comprising:
generating a set of encoded video streams of an input video for adaptive bitrate (ABR) delivery, comprising:
encoding the input video into an initial number of speculative encodings, based at least in part on a respectively determined resolution and quality level setting for individual ones of the speculative encodings;
encoding the input video into a plurality of output encodings using at least one different setting determined from respective quality scores estimated for the plurality of output encodings based at least in part on respective output statistics of the speculative encodings;
estimating for the plurality of output encodings, a plurality of output bit-rates according to different combinations of potential resolution and quality level; and
selecting one or more output encodings from the plurality of output encodings to include in the set of encoded video streams based at least in part on the estimated output bit-rates.
