Major changes: - SaveVideo now uses DynamicCombo to show codec-specific encoding options - When selecting h264 or vp9, quality and speed inputs appear dynamically - Each codec has unique ADVANCED options (shown in 'Show Advanced' section): - h264: Profile (baseline/main/high), Tune (film/animation/grain/etc.) - vp9: Row Multi-threading, Tile Columns - Quality maps to CRF internally with codec-appropriate ranges - Speed presets map to FFmpeg presets New types: - VideoSpeedPreset enum with user-friendly names - quality_to_crf() helper function This demonstrates both DynamicCombo (codec-specific inputs) and advanced widgets (profile/tune/row_mt/tile_columns hidden by default).

Wrap VideoSpeedPreset conversion in try/except to gracefully handle invalid speed_str values instead of raising unhandled ValueError. Logs warning and falls back to None (default) on failure.
Replace silent fallback to libx264 with explicit validation that raises ValueError for unknown codec types. Prevents silent codec substitution.
- Remove redundant pix_fmt assignment (set once instead of in both branches) - Remove unnecessary VideoContainer.AUTO check (format already normalized)
