An online media player provides mechanisms and techniques that allow for real-time edit decision list execution on streaming video to play back an edited video in an online environment. The online media player can request a digital media presentation from at least one server. The online media player can receive an edit decision list and a media effects set from the server, where the edit decision list is associated with the digital media presentation. The online media player can receive streaming media base data, associated with the digital media presentation, from a server. The client applies the edit decision list and upon the streaming media base data in real-time to create the digital media presentation. No file for the complete digital media presentation is fully-rendered and saved prior to play back.
