Time-Selected Special Effect Preview for Faster Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing special effect preview methods are not flexible enough, requiring complete special effect videos to be played from start to end, which is time-consuming and inefficient, degrading the special effect processing experience.
Innovation Solution
A special effect processing method that includes displaying a special effect preview interface with a time setting item, allowing users to set a preview moment for the target special effect, and determining and displaying a special effect preview image based on the set preview moment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If complete special effect video is played from start to end, then the special effect can be previewed, but the preview duration is long and efficiency is low
Solution Approach 1:
The system pre-calculates and stores keyframe information for each special effect element during the production phase. When previewing, it directly retrieves and displays the pre-prepared keyframe images corresponding to the specified time point, rather than playing through the entire video. This preliminary preparation of visual information enables instant preview at any moment, dramatically reducing preview duration while maintaining visual quality.
2Ease of operation
If complete special effect video is played, then all special effect elements can be viewed, but irrelevant information is also displayed
Solution Approach 1:
The system extracts only the necessary visual information for preview by identifying which special effect elements are active at the specified time point and displaying only those elements' keyframe images. Irrelevant information (other special effect elements not active at this moment) is excluded from the preview display. This selective extraction approach maintains preview flexibility while eliminating distracting irrelevant content.
3Reliability
If frame-by-frame playback is used, then the special effect video can be previewed, but the process is time-consuming
Solution Approach 1:
Instead of playing through the actual video frames sequentially, the system uses pre-generated keyframe images that copy the visual appearance of the special effect at specific moments. These keyframe copies capture the essential visual information needed for preview without requiring actual video playback. This copying approach maintains visual accuracy while achieving instant preview delivery, eliminating the time-consuming frame-by-frame playback process.

AI summary
Embodiments of the present disclosure provide a special effect processing method, an electronic device, a storage medium, and a program product. The method includes: displaying a special effect preview interface in response to an effect preview triggering operation for a target special effect, where the special effect preview interface at least includes a time setting item, and the time setting item is used to set a preview moment of the target special effect; and in response to a time setting triggering operation based on the time setting item, determining a special effect preview image according to a set preview moment and the target special effect, and displaying the special effect preview image.
