摘要： In some embodiments, a method analyzes content of a video to generate a representation for a video that represents a relationship of a bitrate to a quality measurement for the video. A plurality of candidate points on the representation are selected. Then, the method selects a profile ladder from at least a portion of the plurality of candidate points. Each profile in the profile ladder is associated with a candidate point and the profile includes a corresponding bitrate and a quality measurement for the respective candidate point. The profile ladder is used for the video.

摘要： In some embodiments, a method generates a representation for a video that represents a relationship of a bitrate to a quality measurement for the video and selects candidate transcoding points on the representation. A plurality of candidate profile ladders are generated based on the candidate transcoding points. Each of the plurality of candidate profile ladders includes a different combination of profiles and a profile is associated with at least one of a bitrate and a quality measurement. The method selects a profile ladder from the plurality of candidate profile ladders based on analyzing the bitrate or the quality of the profile ladder and uses the profile ladder for the video.
