In this way, a stored correspondence between the first image and the first audio is consistent with a correspondence between a picture corresponding to the first image and a sound corresponding to the first audio, thereby implementing audio and image synchronization.

Abstract: Systems and methods are directed to generating a synoptic video from one or more documents. The system receives an indication to generate the synoptic video and in response, accesses the one or more documents and user preferences of a user that are derived by the network system. The one or more documents are analyzed to determine relevant text content, whereby the analyzing includes tagging the relevant text content. Based on the user preferences, the system generates the synoptic video that summarizes the tagged relevant text content. The content and style of the synoptic video is based on a user style indicated by the user preferences. For example, the user preference can determine a depth of the summarized content, a type of audio or text used, an amount of images to provide, and an amount of summarized text to provide. The synoptic video can then be displayed to the user.
