A method and system for generating a depth map corresponding to a frame of a sequence of frames in a video clip is disclosed. This can involve generating a single image depth map for each of a plurality of frames, scaling the single image depth maps, and processing a time sequence of scaled single image depth maps to generate said depth map corresponding to the frame of the sequence of frames in the video clip.

Disclosed herein are methods of synchronizing a media file between two computing devices. The media file includes a file header, at least one descriptor portion enabling reading of media elements in the body portion and at least one file body in which media elements are stored. The synchronizing of the media file occurs between a first copy of the media file stored at a first computing device and a second copy of the media file stored on a second computing device and the synchronization of the second copy of the media file with the first copy of the media file commences before finalization of the first copy of the media file and continues at least while one or more media elements are being written to a file body of the first copy of the media file at the first computing device. Also disclosed are methods of sending synchronization data to the second computing device and updating the second copy of the media file at the second computing device.
