Abstract

A method for editing the playback speed of a partial sequence of video and a digital device therefor are disclosed. A video editing method includes providing a timeline interface corresponding to a video sequence, receiving a first user input for specifying a first location on the timeline interface and a second user input for specifying a second location on the timeline interface, setting an editing interval between the first location and the second location of the timeline interface, receiving a third user input with respect to the editing interval, adjusting at least one of the thickness and length of the editing interval in response to the third user input, and editing playback attributes of the partial sequence based on the adjusted thickness and length of the editing interval.

set an editing interval between the first indicator and the second indicator of the timeline interface, wherein the editing interval corresponds to a partial sequence of the video sequence, and the partial sequence is a sequence between the first frame and the second frame,

receive a third touch input for varying the editing interval, wherein the third touch input is a sliding touch input, and

change a playback speed of the partial sequence according to the third touch input,

wherein the processor is further configured to adjust a thickness of the editing interval of the displayed timeline interface, in response to the playback speed of the partial sequence,

wherein the processor is further configured to display the editing interval in a concaved manner when the thickness of the editing interval is reduced to be equal to or less than a preset thickness, and

wherein a thickness of a central part of the concaved editing internal is proportional to the playback speed the partial sequence.

2. The digital device according to claim 1, wherein the timeline interface includes a plurality of thumbnail images of the video sequence.

3. The digital device according to claim 1, wherein the playback speed of the partial sequence is varied based on an amount of sliding in the sliding touch input.

4. The digital device according to claim 1, wherein the thickness of the editing interval of the displayed timeline interface is enlarged when the playback speed of the partial sequence is increased.

5. The digital device according to claim 1, wherein the thickness of the editing interval of the displayed timeline interface is reduced when the playback speed of the partial sequence is decreased.

6. The digital device according to claim 1, wherein when the third touch input decreases a distance between the first and second indicators, the processor increases the playback speed of the partial sequence.

7. The digital device according to claim 1, wherein when the third touch input increases a distance between the first and second indicators, the processor decreases the playback speed of the partial sequence.

8. The digital device according to claim 1, wherein the processor is further configured to display the editing interval in a convexed manner when the thickness of the editing interval is enlarged to be equal to or less than a preset thickness,

wherein a thickness of a central part of the convexed editing internal is proportional to the playback speed the partial sequence.

9. The digital device according to claim 1, wherein the processor is further configured to display a handle interface for adjusting a thickness of the editing interval.
