Pipeline Test Workflow
Step-by-step validation using BWC footage as baseline test material.
1. Upload BWC Video
Select one of the seven BWC files above. File is hashed (SHA-256) on upload and stored immutably.
2. Audio Extraction
Extract audio track from BWC MP4. Verify audio quality and channel integrity.
3. Dual-Pass Transcription
Run WhisperX transcription with speaker diarization. Identify officers and civilians by voice.
4. Audio Event Detection
Detect gunshots, sirens, vehicle sounds, raised voices, and other critical audio events.
5. Timeline Reconstruction
Build synchronized timeline across multiple BWC angles. Cross-reference timestamps.
6. Generate Report
Export court-ready package with transcript, timeline, audio events, and hash verification.
Expected Results
What to look for when validating pipeline output.
Transcript Accuracy
Verify officer names, commands, and civilian responses are correctly transcribed. Check timestamp alignment.
Speaker Diarization
Confirm officers are distinguished from civilians. Multiple officers should be labeled separately.
Audio Events
Vehicle doors, sirens, radio traffic, raised voices should be detected and timestamped.
Timeline Sync
Multiple BWC angles should align within 1-2 seconds. Check overlapping events.
File Integrity Verification
SHA-256 hashes for baseline BWC files. Any mismatch indicates file modification.
