Methods systems and devices for dynamically creating composite videos

A computer-implemented method for dynamically creating a composite video comprising:

• dynamically creating and playing a composite video in real-time on at least one of multiple invitee mobile computing device, wherein dynamically creating and playing the composite video comprises:
• receiving by the at least one invitee mobile computing device composite video customization data;
• receiving by the at least one invitee mobile computing device data indicating which invitee mobile devices did not submit a video from a server computing device;
• receiving by the at least one invitee mobile computing device data indicating a video playback order from the server computing device;
• editing by the at least one invitee mobile computing device a lead-in video based on the received composite video customization data;
• playing on the at least one invitee mobile computing device the edited lead-in video;
• playing on the at least one invitee mobile computing device a user recorded video after the edited lead-in video;
• receiving by the at least one invitee mobile computing device invitee recorded videos individually from the server computing device;
• playing on the at least one invitee mobile computing device the invitee recorded videos after the user recorded video in an order based on the data indicating the video playback order;
• editing by the at least one invitee mobile computing device a lead-out video to indicate which invitees did not submit a video based on the data indicating which invitee mobile devices did not submit a video;
• and
• playing on the at least one invitee mobile computing device the edited lead-out video;
• wherein the lead-in video is preloaded on the at least one invitee mobile computing device in an unedited form before receiving the composite video customization data, data indicating which invitee mobile devices did not submit a video, data indicating a video playback order, and the invitee recorded videos, and wherein the invitee mobile computing devices are configured to individually edit the unedited lead-in video while the videos are being delivered;
• wherein the lead-out video is preloaded on the at least one invitee mobile computing device in an unedited form before receiving the composite video customization data, data indicating which invitee mobile devices did not submit a video, data indicating a video playback order, and the invitee recorded videos;
• and
• wherein the at least one invitee mobile computing device are configured to play the edited lead-in video, the user recorded video, the individual invitee recorded videos, and the edited lead-out video sequentially as a seamless composite video.
