Abstract:
1. A method of encoding a video, comprising: first, carrying out first motion compensation within a video that has resulted from camera motion, by first finding a group of frames, and finding camera motion among the group of frames, and carrying out first motion compensation within said group of frames that has resulted from camera motion to shift frames in said group of frames in a way that creates a smallest mean square error, and to reduce said error to align the group of frames into a stack, wherein said motion compensation finds borders of said frames as part of said first motion compensation, and wherein said borders are not motion compensated; second, carrying out second motion compensation in the stack that is not resulting from camera motion; encoding said first and second motion compensations separately; and dividing the video into first and second parts, which respectively occupy first and second parts of a total bit budget for compression, separately compressing the first part to create a first compressed part as said first carrying out, and to create a second part to create a second compressed part as said second carrying out, wherein said first compressing and said second compressing use different compression techniques.
