This commit enhances the encoder preset selector with detailed information about speed vs quality trade-offs for each preset option. Preset Information: - Ultrafast: ~10x faster than slow, ~30% larger files - Superfast: ~7x faster than slow, ~20% larger files - Very Fast: ~5x faster than slow, ~15% larger files - Faster: ~3x faster than slow, ~10% larger files - Fast: ~2x faster than slow, ~5% larger files - Medium: Balanced baseline (default) - Slow: ~2x slower than medium, ~5-10% smaller (recommended) - Slower: ~3x slower than medium, ~10-15% smaller - Very Slow: ~5x slower than medium, ~15-20% smaller UI Enhancements: - Dynamic hint label below encoder preset dropdown - Updates automatically when preset changes - Visual icons for different speed categories: - ⚡ Ultrafast/Superfast/Very Fast (prioritize speed) - ⏩ Faster/Fast (good balance) - ⚖️ Medium (baseline) - 🎯 Slow/Slower (recommended for quality) - 🐌 Very Slow (maximum compression) Implementation: - updateEncoderPresetHint() function provides preset details - Called on preset selection change - Initialized with current preset on view load - Positioned directly under preset dropdown for visibility Benefits: - Helps users understand encoding time implications - Shows file size impact of each preset - Recommends "slow" as best quality/size ratio - Prevents confusion about preset differences - Enables informed decisions about encoding settings Technical: - All presets already supported by FFmpeg - No changes to command generation needed - Works with all video codecs (H.264, H.265, VP9, etc.) - Preset names match FFmpeg standards
