Dynamic Special Effect Rendering for Video Highlight Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video processing technologies only support simple graphic layers on each frame, making it difficult for viewers to identify highlighted clips or objects in videos, especially when dynamic emphasis is needed.
Innovation Solution
A method and device for determining target image frames with dynamic special effects, rendering special effect elements based on attributes and coordinates, and synthesizing these effects across frames to create eye-catching dynamic special effects that enhance clip or object identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If simple graphic layers are used on each frame, then device complexity is reduced, but the ability to highlight clips or objects effectively deteriorates
Solution Approach 1:
The patent transitions from static graphic layers to dynamic special effect elements that can move across frames. The special effect elements have attributes including position coordinates that change over time, allowing them to dynamically highlight clips or objects throughout the video sequence rather than being confined to individual frames.
Solution Approach 2:
The patent adds a temporal dimension to special effects by allowing elements to span multiple frames with defined start and end times. This transforms the effect from a two-dimensional static graphic layer to a three-dimensional entity that exists across time, enabling continuous highlighting of moving clips or objects.
2Loss of information
If dynamic special effects spanning multiple frames are implemented, then identification of highlighted content is improved, but device complexity increases
Solution Approach 1:
The patent segments the video into discrete frames and the special effects into discrete elements with specific attributes. Each special effect element is independently defined with properties such as position, size, color, and duration, allowing the system to process and manage complex multi-frame effects through composition of simpler segmented elements.
Solution Approach 2:
The patent uses parameter-based control where special effect elements are defined by a set of attributes (position coordinates, size, color, start time, end time). By changing these parameters, the system can create and manage complex dynamic effects without increasing fundamental processing complexity, as all effects follow the same parameterized model.
3Speed
If static graphic layers are used, then processing speed is maintained, but viewer attention and identification duration are reduced
Solution Approach 1:
The patent performs preliminary action by pre-defining special effect elements with their attributes (position, size, color, duration, start time) before video playback. This allows the effects to be prepared and staged in advance, enabling smooth dynamic rendering during playback without real-time computation overhead that would slow down processing.

AI summary
A video processing method, a video processing device, and a storage medium are provided. The video processing method includes: determining target image frames corresponding to a dynamic special effect in a video and determining an attribute of a special effect element corresponding to the dynamic special effect in each of the target image frames and coordinates of the special effect element. The video processing method also includes: rendering the special effect element on a drawing interface based on the attribute and the coordinates of the special effect element; filling the target image frames into the drawing interface as a background and forming drawing interface frames with the dynamic special effect; and outputting the drawing interface frames corresponding to each of the target image frames.
