Abstract

A system and method for compiling video segments including defining an event; providing a multi-user video aggregation interface; receiving a plurality of video segments through the aggregation interface; determining event-synchronized alignment of the plurality of videos; and assembling a multi-channel video of event, the multi-channel video file configured with at least two video segments that have at least partially overlapping event-synchronized alignment.

Claims

1. A method for compiling video segments comprising:

defining an event;

providing a multi-user video aggregation interface;

receiving a plurality of video segments through the aggregation interface;

determining event-synchronized alignment of the plurality of videos; and

assembling a multi-channel video of event, the multi-channel video file configured with at least two video segments that have at least partially overlapping event-synchronized alignment.

2. The method of claim 1, wherein defining an event includes creating an event resource and adding participants to the event resource;

wherein the received plurality of videos are captured by the participants.

3. The method of claim 2, wherein providing a multi-user video aggregation interface comprises providing a participant application configured to transmit a video segment captured by a participant to a server of the video aggregation interface.

4. The method of claim 3, further comprising, at the participant application, tracking actions of a participant;

automatically generating participant directions based on tracked actions; and

coordinating participant communication to the participant application, which comprises communicating the generated participant directions to at least one participant application.

5. The method of claim 4, wherein tracking actions comprises tracking participant location, quality of captured video segments, and current video capture state.

6. The method of claim 3, wherein receiving a plurality of video segments comprises receiving at least one video segment through a video stream transmitted by the participant application.

7. The method of claim 1, wherein the aggregation interface is a search interface that comprises receiving a search input of a user;

and wherein receiving a plurality of video segments through the aggregation interface comprises selecting video content based on the search input.

8. The method of claim 7, wherein the multi-channel video file configured with at least two video segments is configured to point to a video stream source.

9. The method of claim 1, wherein the aggregation interface is a file upload interface.

10. The method of claim 1, wherein determining event-synchronized alignment of the plurality of videos comprises aligning the plurality of videos according to a unified signal of the plurality of video segments.

11. method of claim 10, wherein the unified signal is an audio signal of the plurality of video segments.

12. The method of claim 11, wherein determining event-synchronized alignment of the plurality of videos further comprises characterizing an identifier of each video segment of the plurality of video segments;

correlating the video segment identifiers; and

aligning video segments for peak correlation of the video segment identifiers.

13. The method of claim 12, wherein a characterized identifier is a hash token extracted from the spectrogram peaks of the audio signal.

14. The method of claim 12, wherein providing a multi-user video aggregation interface comprises providing a participant application configured to transmit a video segment captured by a participant to a server of the video aggregation interface.

15. The method of claim 12, further comprising receiving a new video segment;

and

augmenting the synchronized alignment of at least one video segment of the multi-channel file.

16. The method of claim 1, wherein determining event-synchronized alignment includes synchronizing the timestamps of video segments along a single timeline.

17. The method of claim 1, wherein the plurality of video segments of the multi-channel video file are configured in a media data representation within the file.

18. A method comprising:

defining an event resource;

adding at least a first participant and a second participant to the event resource;

providing a participant application to at least the first participant and the second participant;

receiving a first video segment transmitted from the participant application of the first participant to the multi-channel service;

receiving a second video segment transmitted from the participant application of the second participant to the multi-channel service;

determining event-synchronized alignment of at least the first video segment and the second video segment; and

assembling a multi-channel video file, the multi-channel video file configured with the first video segment and the second video segment overlapping at least partially in event-synchronized alignment.

19. The method of claim 18, wherein determining event-synchronized alignment of at least the first video segment and the second video segment comprises characterizing an identifier of at least the first video segment and the second video segment;

correlating the identifier of the first video segment and the second video segment; and

determining an event-synchronized alignment of the first video segment and the second video segment with peak correlation.
