Systems and methods for selecting resolutions for content optimized encoding of video data

Abstract:

A disclosed computer-implemented method may include receiving a media item for encoding via a content optimized encoding algorithm. The method may also include determining, in accordance with the content optimized encoding algorithm, an overall error model for the media item. The overall error model may include (1) a rate-distortion model for the media item, and (2) a downsampling-distortion model for the media item. The method may also include determining, based on the overall error model, a bitrate cost associated with streaming of the media item within a bitrate lane. The method may further include adjusting the overall error model based on the bitrate cost associated with streaming of the media item within the bitrate lane and encoding the media item for streaming within the bitrate lane based on the adjusted overall error model.
