A method includes identifying replaceable sections among first sections of video encoded at a first bitrate, and replacement sections of the video each encoded at a bitrate that is less than the first bitrate and having encoded therein the video of a corresponding one of the replaceable sections, each replacement section and the corresponding replaceable section having respective measured levels of objective quality that meet a predetermined criterion of objective quality. The method further comprises streaming the first sections of video except for the replaceable sections, and the replacement sections instead of the corresponding replaceable sections.
