Abstract

One or more computing devices, systems, and/or methods for generating and/or presenting time-lapse videos and/or live-stream videos are provided. For example, a plurality of video frames may be extracted from a video. A first set of video frames and a second set of video frames may be identified from the plurality of video frames. The first set of video frames may be combined to generate a first time-lapse video frame and the second set of video frames may be combined to generate a second time-lapse video frame. A time-lapse video may be generated based upon the first time-lapse video frame and the second time-lapse video frame. In another example, a time-lapse video may be generated based upon a recorded video associated with a live-stream video. The time-lapse video may be presented. Responsive to a completion of the presenting the time-lapse video, the live-stream video may be presented.

First claim

What is claimed is:

1. A method for generating a time-lapse video, comprising:
identifying a first set of video frames and a second set of video frames from a plurality of video frames, associated with a video, in a memory structure, the first set of video frames comprising a first number of video frames and the second set of video frames comprising a second number of video frames;
combining the first set of video frames to generate a first time-lapse video frame;
combining the second set of video frames to generate a second time-lapse video frame; and
generating a time-lapse video based upon the first time-lapse video frame and the second time-lapse video frame.

2. The method of claim 1 , comprising:
determining the first number of video frames based upon a first value identified in a window size data structure and the second number of video frames based upon a second value identified in the window size data structure.

3. The method of claim 2 , comprising:
generating a curve based upon an analysis of the video; and
generating the window size data structure based upon the curve.

4. The method of claim 2 , comprising:
determining a third number of video frames based upon a third value identified in the window size data structure;
determining a fourth number of video frames based upon a fourth value identified in the window size data structure;
determining a fifth number of video frames based upon a fifth value identified in the window size data structure; and
identifying a first plurality of sets of video frames corresponding to the third number of video frames, a second plurality of sets of video frames corresponding to the fourth number of video frames and a third plurality of sets of video frames corresponding to the fifth number of video frames from the plurality of video frames.

5. The method of claim 4 , comprising:
combining the first plurality of sets of video frames to generate a first plurality of time-lapse video frames;
combining the second plurality of sets of video frames to generate a second plurality of time-lapse video frames; and
combining the third plurality of sets of video frames to generate a third plurality of time-lapse video frames.

6. The method of claim 5 , the time-lapse video generated based upon the first plurality of time-lapse video frames, the second plurality of time-lapse video frames and the third plurality of time-lapse video frames, the method comprising:
providing for displaying a first portion of the time-lapse video comprising the first plurality of time-lapse video frames;
providing for displaying a second portion of the time-lapse video comprising the second plurality of time-lapse video frames after the displaying the first portion of the time-lapse video; and
providing for displaying a third portion of the time-lapse video comprising the third plurality of time-lapse video frames after the displaying the second plurality of time-lapse video frames.

7. The method of claim 6 ,
the third number of video frames less than the fourth number of video frames; and
the fifth number of video frames less than the fourth number of video frames.

8. The method of claim 7 ,
the first portion of the time-lapse video comprising a representation of a first portion of the video at a first speed;
the second portion of the time-lapse video comprising a representation of a second portion of the video at a second speed; and
the third portion of the time-lapse video comprising a representation of a third portion of the video at a third speed, the first speed less than the second speed and the third speed less than the second speed.

9. The method of claim 1 ,
the first number of video frames equal to the second number of video frames.

10. The method of claim 1 ,
the first number of video frames not equal to the second number of video frames.

11. The method of claim 1 ,
the combining the first set of video frames comprising averaging the first set of video frames; and
the combining the second set of video frames comprising averaging the second set of video frames.

12. The method of claim 1 ,
the first set of video frames comprising one or more video frames that are also in the second set of video frames.

13. A method for presenting a live-stream video, comprising:
determining a time-lapse video associated with a recorded video associated with a live-stream video;
responsive to receiving a request to access the live-stream video, presenting the time-lapse video; and
responsive to a completion of the presenting the time-lapse video, presenting the live-stream video from a first starting time.

14. The method of claim 13 ,
a plurality of video frames associated with the time-lapse video ending with a last video frame;
the live-stream video beginning with a first live-stream video frame; and
the first live-stream video frame representing a continuation of the last video frame.

15. The method of claim 13 , the request to access the live-stream video received at a first time, the method comprising:
responsive to receiving a request to access the live-stream video at a second time, presenting a second time-lapse video associated with the live-stream video; and
responsive to a completion of the presenting the second time-lapse video, presenting the live-stream video from a second starting time.

16. A computing device comprising:
a processor; and
memory comprising processor-executable instructions that when executed by the processor cause performance of operations, the operations comprising:
identifying a first set of video frames and a second set of video frames from a plurality of video frames associated with a video, the first set of video frames comprising a first number of video frames and the second set of video frames comprising a second number of video frames;
combining the first set of video frames to generate a first time-lapse video frame;
combining the second set of video frames to generate a second time-lapse video frame; and
generating a time-lapse video based upon the first time-lapse video frame and the second time-lapse video frame.

17. The computing device of claim 16 ,
the first number of video frames equal to the second number of video frames.

18. The computing device of claim 16 ,
the first number of video frames not equal to the second number of video frames.

19. The computing device of claim 16 ,
the combining the first set of video frames comprising averaging the first set of video frames; and
the combining the second set of video frames comprising averaging the second set of video frames.

20. The computing device of claim 16 ,
the first set of video frames comprising one or more video frames that are also in the second set of video frames.
