Interrupted recording
The device stopped before the MP4 file could be finalized correctly.

REC(over)
Lost doesn't always mean gone.
Recover damaged MP4 recordings by rebuilding supported structures and recovering valid AVC/H.264 video whenever possible.
The app is approved for Microsoft Store. Public release is being coordinated with its product page and Full upgrade.
The problem
When a recording will not play, the video may still be there.
An interrupted recording, sudden power loss, battery removal or damaged storage can leave an MP4 file unreadable even when much of its video data remains intact.
REC(over) examines what is still valid before deciding how the file should be recovered.
Analyze before you recover
Understand the damage first.
REC(over) inspects the MP4 container, AVC/H.264 configuration, media samples, NAL units, IDR frames, reference dependencies and supported fragmented MP4 structures.
Only after the analysis does it select an appropriate recovery strategy and create a separate output file.
Designed for situations like these
Damage caused by interruption, not absence.
Power failure
The recording ended suddenly because the camera or recorder lost power.
Battery removal
Required MP4 initialization structures were not completely written.
Corrupted storage
The recording still exists, but part of the MP4 structure became unreadable.
How REC(over) works
Analyze. Detect. Recover. Validate.
- Analyze the damaged recording. Inspect the container and identify valid media data.
- Detect a suitable strategy. Determine which supported structures can be rebuilt safely.
- Recover into a new file. Generate playable output whenever sufficient valid data remains.
- Validate the result. Check the recovered MP4 before reporting success.
Capabilities
Focused recovery for damaged MP4 AVC/H.264 recordings.
Analysis
- MP4 structure inspection.
- AVC/H.264 detection and configuration validation.
- NAL, sample, IDR and reference-frame analysis.
- Supported fragmented MP4 inspection.
- Automatic recovery-strategy selection.
Recovery
- Supported MP4 structure reconstruction.

Trial and Full
Verify recoverability before unlocking the complete result.
The Trial performs the same complete analysis as Full, but produces a short sample instead of the entire recovered file.
| Feature | Trial | Full |
|---|---|---|
| Complete file analysis | Yes | Yes |
| Recovery report | Yes | Yes |
| 10-second recoverable sample | Yes | No |
| Complete recovery | No | Yes |
Safe by design
Your original recording remains untouched.
REC(over) never overwrites the source file. Recovered content is written to a new output file selected by the user.
All analysis and recovery are performed locally on the Windows computer. Files are not uploaded to tioleo servers.

FAQ
Common questions
Can REC(over) recover every damaged recording?
No. Recovery depends on how much valid structure and media data remain available.
Does REC(over) modify the original file?
Never. It creates a separate recovered output file.
Why does Trial generate only 10 seconds?
It lets you verify the recovery result before purchasing Full.
Is an Internet connection required?
Only for Microsoft Store licensing and purchase validation. File processing is local.
