Claim 0:
1. A method for online per-title encoding, comprising:
receiving a video input;
generating a plurality of segments of the video input;
for at least one segment of the plurality of segments of the video input, extracting a spatial feature and a temporal feature;
predicting a bitrate-resolution pairs based on the spatial feature and the temporal feature, using a discrete cosine transform (DCT)-based energy function, the bitrate-resolution pairs indicating an optimal resolution for each of a plurality of target bitrates; and
per-title encoding the at least one segment for the predicted bitrate-resolution pairs,
wherein predicting the bitrate-resolution pair comprises determining a resolution scaling factor for each bitrate in a set of bitrates.
