Video Editing Timeline Interface Thickness Speed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video editing methods lack simplicity and intuitiveness in user input for editing video sequences, particularly in adjusting playback speed, and fail to provide clear visual representations of these adjustments.
Innovation Solution
A digital device with a video editing method that utilizes a timeline interface where the thickness of an editing interval corresponds to playback speed and length to playback duration, allowing users to intuitively adjust playback attributes through user inputs like touch and drag, enabling easy recognition of speed changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional video editing methods are used with multiple user inputs for selecting intervals and adjusting playback speed, then precise control over video editing is achieved, but the operation becomes complex and not intuitive for users
Solution Approach 1:
The patent maps the one-dimensional concept of playback speed to a two-dimensional visual representation where playback speed is represented by the thickness of the editing interval on the timeline. This dimensional transformation allows users to intuitively grasp and control playback speed through visual cues rather than abstract numerical inputs, resolving the contradiction between ease of operation and operational complexity
Solution Approach 2:
The patent employs visual changes in the editing interval representation, specifically varying the thickness (dimensional property) of the interval to indicate different playback speeds. This visual feedback mechanism makes the abstract concept of playback speed tangible and intuitive, allowing users to easily understand and control editing parameters without complex operations
2Loss of information
If playback speed adjustment is made through traditional controls, then precise speed control is achieved, but the playback speed changes are not visually clear to users
Solution Approach 1:
The patent transforms the invisible parameter of playback speed into a visible dimensional property by representing playback speed as the thickness of the editing interval on the timeline. This allows users to visually detect and measure playback speed changes directly on the interface, eliminating the loss of information and making speed adjustments immediately apparent
Solution Approach 2:
The patent implements immediate visual feedback by dynamically adjusting the thickness of the editing interval to reflect current playback speed settings. This continuous feedback loop allows users to see the effect of their adjustments in real-time, making it easy to detect and measure playback speed changes without additional controls or indicators

AI summary
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.
