Frequently Asked Questions

What types of video corruption can this tool fix?

This tool can fix: missing moov atoms (video won't start), truncated files (interrupted recordings), corrupted headers, damaged frames with visual artifacts, audio/video desync, broken timestamps causing seeking issues, and container format problems.

What is the difference between repair modes?

Quick Fix remuxes the file (lossless, fast) — fixes container and header issues. Deep Repair re-encodes the entire video — fixes frame-level corruption. Recovery mode uses maximum effort for severely damaged files. Auto mode tries strategies in order until one works.

What is the maximum file size?

The recommended limit is 500 MB. Files up to 1 GB are supported but processing may take several minutes depending on your device. All processing uses your device's memory.

Why is the Health Score not 100 after repair?

Some damage is irrecoverable — for example, if part of the video data is permanently lost (truncated recording). The tool recovers as much as possible, but the recovery score shows what percentage was salvaged.

Can this fix videos from drones, dashcams, or security cameras?

Yes. Corrupted recordings from drones, dashcams, GoPro, security cameras, and phone recordings are common use cases. The tool handles interrupted recordings, power-loss damage, and SD card errors.
