Abstract
A system identifies a change in a position of an object from a first frame to a second frame from a plurality of frames. The video is comprised of a plurality of frames. In one embodiment, the plurality is at least three frames. The image stability measuring process identifies a change in direction of the change in the position of the object. The change in direction is determined by utilizing a plurality of adjacent frames located near the first frame and the second frame. The image stability measuring process determines an image stability value for a subset of the plurality of frames. The image stability value is calculated based on the change in direction. The image stability measuring process renders a portion of the video within an automatic editing script. The portion of the video is selected based on a preferred image stability value identified within the automatic editing script.
