Methods, systems, and apparatus for collaborative media editing. In one aspect, a method includes presenting, to an originator, an originator interface including multiple media panes; establishing a connection with a collaborator; receiving from the originator a selection indicating an item of media content associated with at least one of the multiple media panes; transmitting to the collaborator the selected item of media content; and enabling inter-user communication relating to the selected item of media content in the originator interface with the collaborator. Further, a connection can be established with a second collaborator, the item of media content can be transmitted to the second collaborator, and communication can occur in the originator interface with the second collaborator.
