Container, codecs, bitrate —
the spec of any media file

Drop in an audio or video file and get the truth: container, every stream it holds, codecs, duration, resolution, bit rate, sample rate — and the one thing that usually explains why it won't play.

The file stays private. It is never stored, listed, or shown to anyone else. Mediaread runs ffprobe — the same tool engineers use on the command line — and makes its output legible. Within seconds you see:

Container: MP4
Duration: 00:02:04.38
Overall bit rate: 2,500 kbps
Streams: 2 (1 video, 1 audio)
—
Video: H.264, 1920×1080, 23.976 fps, 2,000 kbps
Audio: AAC, 48,000 Hz, stereo, 256 kbps

Why it won't play

The most useful part of the report is the Issues section. Mediaread flags common problems: a codec the browser refuses, a stream marked with the wrong language, a duration that doesn't match the actual content, audio at a sample rate nothing expects.

⚠ Audio sample rate: 24 kHz
Most browsers expect 44.1 or 48 kHz. This file may play without sound.
✓ Video codec is H.264 — supported everywhere.

See the content at a glance

Mediaread pulls frames at even intervals so you can tell whether the file is what you think it is — a black first frame, a slate, or entirely different content.

How it works

  1. Upload the file

    Drag and drop or select any audio or video file. Files up to 500 MB are accepted.

  2. We inspect every stream

    Behind the scenes, ffprobe reads the container and every stream inside it — codec, resolution, bitrate, sample rate, language tags, and more.

  3. Read the report

    The results are presented in clear, labelled sections: Container, Video, Audio, and Issues. Each section shows only what the file actually contains — nothing is guessed or inferred.
