Choosing the Compression Ratio
Different compression ratios produce different file sizes and quality. Choose the level that suits your needs:
| Level | Characteristics | Best for |
|---|---|---|
| Low ratio | Quality close to original, smaller size reduction | High-quality archives and fine-cut works |
| Medium ratio | Balanced between quality and size | Daily sharing and regular uploads |
| High ratio | Significant size reduction, slight quality loss | Strict upload limits or long-term storage |
| Very high ratio | Tiny files with noticeable quality loss | Preview and quick sharing where quality is not critical |
