The three video enhancement modes provided by SVLS correspond to different usage scenarios and technical implementations:
1. No enhancement mode (none)
- specificities: Full preservation of the original video quality, lip-synchronization only
- Applicable Scenarios: Used when the input video itself is of high quality (e.g., shot by a professional camcorder), or when the original style needs to be maintained
- processing speed: Fastest, no additional computing resources required
2. Lip enhancement mode (lip)
- specificities: Specialized enhancement of the lips and surrounding area using super-resolution techniques (typically 20-30 pixel range)
- Applicable Scenarios: when there is a need to emphasize articulatory accuracy, or when the original video lip area resolution is insufficient
- dominance: Moderate computational volume, significantly improves articulation visibility
3. Full face enhancement mode (face)
- specificities: Enhancement of the entire facial area, including skin texture, hair details, etc.
- Applicable Scenarios: When the video requires high quality close-ups, or when the original video has significant compression artifacts
- take note of: the most computationally intensive and may require more powerful GPU support
Selection RecommendationsFor most application scenarios, it is recommended to try the lip mode first; if you need movie-level quality, then use the face mode; when dealing with 4K originals or special artistic effects, use the none mode. Mr. can be made into a small sample film to compare the three effects before deciding.
