A processing device provides, on a mobile device, a storyline content user interface (UI) for adding video content to a storyline, the storyline content UI having a first area including a media player, a second area including visual representations of video clips from the storyline, and a third area including a first UI element to record video content, and a second UI element to add the recorded video content to the storyline. In response to a user activation of the first UI element, the processing device initiates recording of a new video clip using the first area, creating, by a processing device, a visual representation of the new video clip, and adding the visual representation of the new video clip to the second area. In response to a user activation of the second UI element, the processing device causes the new video clip to be associated with the storyline. In response to a user selection of the visual representation of the new video clip, the processing device plays the new video clip in the first area.
