Abstract
Methods, apparatus and systems related to packaging a multimedia content for distribution are described. In one example aspect, a method includes receiving media files comprising video or audio data captured at a production stage and determining a hierarchical structure of the multimedia content based on production stage information of the multimedia content. The hierarchical structure indicates that the multimedia content comprises multiple scenes, each of which comprises multiple shots produced with corresponding devices and cast. The method also includes identifying characteristics associated with the individual scenes based on the production stage information, generating multiple copies of the multimedia content at different compression levels, and dividing each of the multiple copies of the multimedia content into segments based on the hierarchical structure. The compression levels and a length of a segment are adaptively adjusted based on the characteristics associated with the individual scenes.
