How to repair a video

  1. Add your videos — up to 10.
  2. Nothing to set.
  3. Click Repair and download the rebuilt copy.
Is my video safe?

Yes. Your video is only used to create your result — it’s never shared and never used to train AI.

What can it fix?

Broken indexes, wrong durations and timing glitches from apps that wrote the file badly. The streams are copied as they are, so quality doesn't change.

What can't it fix?

A recording that was cut off before it was finalised (often missing its index entirely) can't be read here — you'll get a clear message instead of a broken file.
