Video Style Switching Animation for Smoother Clip Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video processing technologies require users to prepare separate video clips with different image styles and suffer from rigid and non-smooth transitions, reducing user experience.
Innovation Solution
A video processing method that displays an initial image, triggers an image switching animation to transition to a target image with different styles, and completes the animation to display the target image, using a first image area for a switching material, a second area for the initial image, and a third area for the target image, with dynamic position and shape changes.

Engineering Contradiction Analysis
1Measurement precision
If motion compensation is performed using reference images from different frames, then motion compensation accuracy is improved, but processing time increases due to additional search and matching operations
Solution Approach 1:
The patent performs preliminary action by pre-calculating and storing motion vectors for multiple candidate reference images before the actual motion compensation process. This allows the system to quickly select and apply the best motion vector without performing time-consuming search and matching operations during processing, thus improving accuracy while reducing processing time.
Solution Approach 2:
The patent segments the motion compensation process into multiple stages: first identifying candidate reference images, then calculating motion vectors for each candidate, and finally selecting the optimal motion vector for compensation. This segmentation allows parallel processing and optimization of each stage independently, reducing overall processing time while maintaining high accuracy.
2Measurement precision
If multiple reference images are used for motion compensation, then compensation accuracy is improved, but device complexity increases due to additional processing steps
Solution Approach 1:
The patent applies multi-functionality by using a unified motion vector calculation mechanism that works for all candidate reference images. The same algorithm and processing pipeline are used to calculate motion vectors for different reference images, reducing the complexity increase that would result from implementing separate processing steps for each reference image.
Solution Approach 2:
The patent creates copies of motion vector data for different reference images and stores them in a ready-to-use format. This copying approach allows the system to quickly retrieve and apply motion vectors without re-calculating them, simplifying the processing steps while maintaining the ability to use multiple reference images for high accuracy compensation.

AI summary
A video processing method, a video processing apparatus, an electronic device and a computer-readable storage medium. The video processing method comprises: displaying an initial image, wherein the initial image comprises a first-style image (S10); in response to a first trigger event, displaying an image switching animation, wherein the image switching animation is used for presenting a dynamic process of the switching from the initial image to a target image, and the target image comprises a second-style image (S20); and in response to the completion of the displaying of the image switching animation, displaying the target image (S30), wherein a switching image in the image switching animation comprises a first image area, a second image area and a third image area, and the first image area covers the entire image area of the image switching animation during the dynamic process by means of position movement and in a time-sharing manner, and has a change in shape during a position movement process. By means of the method, the complexity of a user preparing video clips of different image styles can be reduced, such that the switching between the video clips of different image styles is smoother, and a new video clip switching mode is provided, thereby improving the user experience.
