Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video editing systems face challenges in effectively generating and applying various effects, particularly in short video formats, due to the complexity of integrating user-selected materials and maintaining accurate positional relationships between face and effect elements.
Innovation Solution
A method and apparatus for generating video effects that involve acquiring user-selected materials, displaying a preview effect, determining target part images, and updating the effect based on these images, using camera processing modules to overlay and position elements accurately, and allowing for real-time editing and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple effect materials and face images are integrated in video editing, then the visual quality and diversity of effects are improved, but the complexity of maintaining accurate positional relationships between elements increases
Solution Approach 1:
The system segments the effect generation process into distinct modules: face image processing, effect material selection, preview generation, and final effect creation. Each module handles specific tasks independently, making the complex process manageable and maintainable while supporting diverse effect materials including images, videos, and stickers.
Solution Approach 2:
The effect preview serves as an intermediary between user selection and final effect generation. It allows users to adjust positional relationships and preview the combined effect of face images and effect materials before finalizing, thereby simplifying the complexity of direct integration.
2Ease of operation
If users can freely select and position effect materials, then the ease of operation is improved, but the time required for effect generation and processing increases
Solution Approach 1:
The system performs preliminary actions by pre-processing face images (detecting landmarks, segments, and features) and pre-loading effect materials before the user finalizes their selection. This preparation reduces the time required for effect generation while maintaining user control over the final composition.
Solution Approach 2:
The effect preview provides real-time feedback to users as they select and position effect materials. This allows users to see the impact of their choices immediately and make adjustments without lengthy processing delays, balancing ease of operation with efficient processing.
3Manufacturing precision
If the system processes and renders multiple effect materials in real-time, then the quality of effect preview is improved, but the computational energy consumption increases
Solution Approach 1:
The system applies partial processing to the effect preview by rendering only the essential components at high quality while using optimized or compressed rendering for less critical elements. This approach maintains perceptual quality while reducing the computational energy required for real-time processing of all effect materials.

AI summary
Provided in the present disclosure are a special-effect generation method and apparatus, and a computer device and a storage medium. The method comprises: in response to a selection operation of a user, acquiring a selected special-effect material; presenting, on a special-effect editing page, a special-effect preview effect which comprises a facial image and the special-effect material; in response to a selection operation for a target part, determining, from the facial image, a target part image corresponding to the target part, and updating the special-effect preview effect on the basis of the target part image; and in response to a determination operation for the updated special-effect preview effect, generating a target special effect on the basis of presentation information of the target part in the updated special-effect preview effect and the special-effect material. In this way, special-effect generation methods can be enriched, thereby improving the diversity and the special-effect quality of a generated special effect.
