Complete 6-Step Execution Guide
Import Corrupted Video Files
Click + Add Video or drag and drop your corrupted video files into the application window. The tool automatically detects camera hardware metadata and codec specifications.
Quick Steps
- 1
Click + Add Video and select your unplayable video recording.
- 2
The software inspects the container header and identifies camera parameters.
- 3
Click Next: Run Diagnostics → to analyze the damage.
Tip: You can queue multiple corrupted videos simultaneously for batch processing.
Deep Container Diagnostics & Analysis
The forensics engine analyzes ISOBMFF atom structures, checks the mdat media payload, detects missing MOOV atoms, and flags playback error codes (0xc00d36c4, 0xc00d5212, QuickTime 2048).
Quick Steps
- 1
View the real-time atom tree and corruption severity score.
- 2
The tool automatically detects if codec headers or seek tables are damaged.
- 3
Proceed to automatic header rebuilding or sample repair.
Tip: Standard index corruptions are repaired automatically in seconds.
Advanced Sample Repair (Reference Video)
For unfinalized videos cut short by drone crashes or sudden battery power loss, provide a working reference video recorded on the same camera model with identical resolution to synthesize missing sample tables.
Quick Steps
- 1
Click Select Reference Video and choose a healthy video from the same camera.
- 2
The Untrunc engine extracts timescale and codec sample parameters from the donor.
- 3
Click Synthesize Headers to reconstruct the damaged bitstream index.
Tip: A 10-second working clip from the same device is sufficient to restore hours of lost footage.
Preview Repaired Video & Audio Sync
Watch your restored video in the integrated media player. Use the real-time audio delay slider (-2000ms to +2000ms) to calibrate audio-video synchronization if drift occurred.
Quick Steps

Click Play to watch the 1-minute high-definition preview.
- 2
Scrub through the timeline to verify frame integrity and color grading.

Quick Steps
- 1
Choose your target container (MP4, MOV, MKV).
- 2
Select a destination folder on your local SSD or hard drive.
- 3
Click Start Lossless Export to write the repaired video.
Tip: Direct stream copy runs up to 50x faster than traditional video converters.
