Check these first
- 1
Play from beginning to end in two independent players.
- 2
Compare file size with the expected duration and bitrate.
- 3
Inspect duration, codec, and metadata.
- 4
Copy the file again from its original source.
Reliable fixes
- Recover from the original source when possible.
- A converter cannot recreate missing bytes.
- Avoid overwriting the only copy during repair attempts.
Change one variable at a time and test with a short known-good file. That separates a damaged source from a browser, codec, or memory limitation.
