Video stabilization

摘要

Aspects of the technology described herein provide a method of editing video to improve the apparent stability of the video footage. In one aspect, the apparent stability of the video image is improved by adding a border around an image captured within individual video frames and adjusting the relative position of consecutive video frames according to a negative of a movement vector calculated between the two consecutive frames.

主权项

1. A computing system comprising:
a processor; and computer storage media having computer-executable instructions stored thereon which, when executed by the processor, implement a method of video editing to correct for camera movement during video recording, the method comprising:
receiving a video comprising a plurality of frames, each frame having an original height and width;generating a plurality of bordered frames by adding a border around a perimeter of individual video frames from the plurality of frames;calculating a motion vector that expresses a movement of a video camera while filming the video; andgenerating a stabilized video by recombining the plurality of bordered frames and correcting for the movement by adjusting a location of individual frames relative to other frames using the motion vector,wherein a width of the border is an average of the motion vector for each frame in the video plus a standard deviation of the average of the motion vector.
