Smart Clip Deduplication Engine, Sub-Millisecond Audio Cross-Correlation & Seamless Hardware Merge

  • Modular Deduplication Engine (DeduplicationService.cs): Standalone deduplication service with DeduplicationEntry records tracking origin-child clip relationships, duration, and millisecond timestamps stored in %AppData%\Backtrack\deduplicated.json.
  • Sub-Millisecond Acoustic Overlap Alignment: Mathematical audio fingerprinting using 8kHz normalized cross-correlation (DetectOverlapOffsetSeconds) to detect the exact splice point down to 0.125ms across OBS keyframe boundaries, completely eliminating repeated frames and audio stutter.
  • High-Precision Timestamp Fallback: Automatic millisecond timestamp tracking (ExactDurationSeconds) for videos with no audio or silent tracks.
  • Hardware-Accelerated Seamless Merge Engine (MainWindow.Merge.cs): Fast GPU hardware-accelerated filter concatenation with monotonic PTS presentation normalization (setpts=PTS-STARTPTS, asetpts=PTS-STARTPTS,aresample=async=1000) and 1-second GOP keyframes (-g 60 -keyint_min 30) for instant seeking in media players.
  • Multi-Track Audio Concat & Preservation: Stream-copy and multi-stream filter complex mapping preserving all discrete audio tracks (game audio, mic, discord, desktop audio).
  • Gallery Drag-and-Drop Merge & Themed Overlays: Drag deduplicated clip cards onto their origin to merge with live progress. Added floating themed pill cards (BadgeBg, BadgeBorder, Text0) for merge/compress progress and dynamic luminance calculations for compress preset buttons across all themes.
