Local media inspection

Codec and Container Detector

Inspect a media file before repairing or converting it. The browser checks container, codecs, duration, resolution, and observed FPS without uploading the file.

How it works

Choose a video or audio file.
The browser asks FFmpeg to read the local stream metadata.
Use the result to pick a repair, conversion, or publishing tool.

Private by default

The file is loaded into browser memory and inspected locally. Nothing is uploaded.

FAQ

Can this repair files?

No. This page only identifies stream metadata. Use the repair tools after you know what kind of file you have.

Why is FPS approximate?

FFmpeg reports observed stream timing. Some variable-frame-rate recordings may show a rounded or representative value.

Cleaner recordings upstream

Aufzeichna helps avoid repair work with controlled exports, smooth cursor motion, and polished screen recordings.
