Can this repair an AVI with a missing or broken index?

Yes. AVI v1 repair is designed to rebuild missing playback indexes when the file still contains recoverable media chunks.

Do I need to convert AVI to MP4 before repair?

No. Repair the AVI first. Converting a corrupted file before repair can make recovery harder and hide the original structure problem.

Does AVI repair support every AVI variant?

Current support focuses on classic AVI files. Some newer OpenDML variants or files with missing media payload may not be recoverable.

Can a reference AVI improve repair quality?

Yes. A healthy AVI from the same device and settings can help recover headers or stream timing when the damaged file has lost too much metadata.

Built for users who need quick AVI recovery without converting damaged files before testing playback.
