Video Effect Preview Using Virtual Frames and Timeline Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video processing systems lack a complete preview of effect application, making it difficult for users to accurately select and apply effect styles to videos, thereby reducing user experience.
Innovation Solution
Generate a virtual video frame based on a pointer position on a video track and synchronize its playback with the corresponding video clip to provide a complete preview of the effect application, allowing users to make more informed selections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only a single frame preview function is supported, then the device complexity is low, but the completeness of preview information is insufficient
Solution Approach 1:
The patent creates a virtual video frame that copies and simulates the actual video playback with effect styles applied. This virtual frame serves as a complete preview representation without requiring full video processing, thus providing comprehensive preview information while controlling system complexity through virtualization rather than physical duplication of the entire video processing pipeline.
Solution Approach 2:
The system performs preliminary rendering of the effect styles on a virtual video frame before actual video processing. By pre-generating the preview content with all effect styles applied in advance, the system provides complete preview information including duration and visual effects, while avoiding the complexity of real-time processing during actual playback.
2Reliability
If a virtual video frame is generated and played synchronously with the video clip, then the realism of preview effect is improved, but the processing time and computational resources increase
Solution Approach 1:
Instead of processing the entire video clip with effect styles applied, the system creates a simplified virtual video frame that copies only the essential visual characteristics and effect applications. This virtual representation maintains preview realism while dramatically reducing processing time by working with a single frame rather than the complete video sequence.
Solution Approach 2:
The system applies effect styles to a virtual video frame with partial action - rendering only the necessary visual elements needed for preview purposes rather than processing the complete video. This provides sufficient realism for user decision-making without the excessive processing time required for full video rendering.

AI summary
The present disclosure provides a previewing method and apparatus for an effect application, and a device and a storage medium. The method comprises: in response to a preview triggering operation for a target effect style, taking the position of a pointer on a video track as a starting point, and generating a virtual video frame for the target effect style; and synchronously playing the virtual video frame and a video clip corresponding to the virtual video frame on the video track on the basis of a time axis, to preview the effect of the target effect style applied to the video clip. According to the present disclosure, in a mode of generating a virtual video frame for the target effect style and synchronously playing the virtual video frame with the video clip, the method achieves the preview of the complete picture effect of the video clip in a manner of playing the video clip, so that a user is helped to make a more satisfactory choice when performing effect processing on the video with a more real preview effect, and the use experience of the user is improved.
