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.
Claims24
A video editing method comprising:
- displaying a timeline interface corresponding to a video sequence, wherein the timeline interface displays a plurality of thumbnail images of the video sequence at a preset interval on the timeline interface;
- specifying a first location on the timeline interface by receiving a first touch input, and a second location on the timeline interface by receiving a second touch input, wherein the first location corresponds to a first frame of the video sequence and the second location corresponds to a second frame of the video sequence;
- setting an editing interval between the first location and the second location of the timeline interface, wherein the setting includes displacing a first indicator corresponding to the first frame and a second indicator corresponding to the second frame at both ends of the editing interval, at least one of the first indicator and the second indicator is movable on the timeline interface, 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 of the video sequence;
- receiving a third touch input with respect to the editing interval, wherein the third touch input includes a touch input of sliding at least one of the first indicator and the second indicator along the timeline interface;
- adjusting a thickness and length of the editing interval in response to the third touch input, wherein the thickness of the editing interval is proportional to a playback speed of the partial sequence, and the length of the editing interval is proportional to a playback duration of the partial sequence, wherein the playback speed of the partial sequence increases when the thickness of the editing interval is enlarged, and the playback speed of the partial sequence decreases when the thickness of the editing interval is reduced, and wherein the playback speed of the partial sequence increases when the length of the editing interval is shortened, and the playback speed of the partial sequence decreases when the length of the editing interval is enlarged;
- and
- changing playback attributes of the partial sequence according to the adjusted thickness and length of the editing interval, wherein the playback attributes of the partial sequence include the playback speed of the partial sequence.
