Download attempted repair

A downloadable file is not proof of successful recovery. Play it and inspect its duration and contents.

What this tool can and cannot do
Diagnostics: Inspect basic MP4/MOV container markers and attempt a browser playback test.
Structural repair: FFmpeg attempts to remux readable media without re-encoding it.
Secondary attempt: If remuxing fails, FFmpeg attempts to decode and re-encode readable streams.
Not implemented: Rebuilding a missing MP4 index from a reference recording, proprietary camera recovery, raw storage carving, or recovery of missing video data. A reference file is analyzed only; it is not used to reconstruct the damaged file.
