MP4 Repair Tool

The tool analyzes the MP4 container to identify structure such as moov, mdat, and track atoms, validating their presence and coherence. It attempts to repair gaps by reallocating index tables and timestamps to restore playback without re-encoding.
Conceptually, repair operates in offline mode: it does non-destructive analysis, writes a recovered file, and produces a log with decisions. It handles common corruption scenarios, including missing moov, damaged frames, and corrupted sample sizes.
This tool benefits editors, archivists, QA teams, and forensic analysts who need to salvage footage from damaged transfers or storage. Its value lies in predictable, transparent processing and the ability to produce a playable legacy copy, preserving as much data as feasible.
Core features include container validation, moov/mdat reconciliation, selective frame recovery, optional deep repair, and detailed reporting. Advanced users can run batch repairs, inspect diagnostics, and route outputs to defined repositories for archival workflows.
