Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for providing event-specific media content. One of the methods includes receiving, by a social messaging platform, an indication of a message by a user of client software on a first user device; receiving, from the first user device, a first location of the first user device; providing, to the first user device, one or more topics that are specific to an event temporally associated with the first location; receiving, the message for posting on the social messaging platform, the message including (i) a topic selected from the one or more topics, and (ii) user selected media content; and adding the message to one or more streams of the social messaging platform.

Abstract: A method includes capturing a first segment of video content, and displaying the video content of the captured first segment in a first page of a graphical user interface (GUI) of an application executing on a mobile device as the first segment is being captured, where the GUI is displayed on a touchscreen. A second segment of video content is captured, where the second segment is not temporally contiguous with the first segment, and, as the second segment is being captured, a first static screenshot of a frame of the first segment of video content is displayed in the page of the GUI and the video content of the captured second segment is also displayed in the page of the GUI.
