Techniques described herein include systems and methods for synchronizing multiple content streams for an event. A reference time point for an event being live-streamed by a plurality of streaming devices may be maintained. A plurality of content streams and manifest files may be received from streaming devices for the event where a manifest file includes a segment template and a timeline for a segment of content included in a content stream. The timeline may identify a capture time for the content generated by an associated streaming device of the streaming devices. The plurality of content streams may be synchronized by modifying the manifest files based on the capture times included in the manifest files and the reference time point. The plurality of content streams and the modified manifest files may be transmitted to a content viewing computer with instructions for synchronizing playback.

Synchronize and present multiple live content streams

Techniques described herein include systems and methods for identifying areas of a user interface to position overlay content without obscuring primary content. A scene in a content stream may be identified based on one or more user interface elements included in the content stream. Boundaries and positions of the one or more user interface elements may be identified in the scene based on an edge detection algorithm. A prominence value may be determined for a container that corresponds to an area of a user interface that includes the one or more user interface elements based on aggregate user input for the scene. Instructions for updating the scene may be transmitted to a user device to incorporate an overlay that includes containers that correspond to areas of the user interface that enables a user to place an overlay user interface element in a particular container based on the prominence value.
