Overview

The Media Metadata to JSON tool allows you to extract comprehensive technical details from audio and video files using ffprobe. Upload your media file to instantly generate a structured JSON output containing codecs, streams, chapters, tags, duration, bitrate, and container information.

When to use

When you need to inspect the internal stream structure, codecs, or container format of a video or audio file.
When automating media processing pipelines and requiring structured JSON metadata for validation.
When troubleshooting playback issues by checking audio/video bitrates, sample rates, or missing metadata tags.

How it works

1Upload your audio or video file using the file selector.
2The tool processes the file using ffprobe to analyze its container, streams, and metadata.
3The extracted metadata is formatted and displayed as a structured JSON object.
4Copy or download the JSON output for use in your development workflows or documentation.

Use cases

Verifying video codec and resolution compliance before uploading to streaming platforms.
Extracting chapter markers and tag information from audiobooks or podcasts.
Auditing media libraries to identify files with low bitrates or unsupported audio formats.

Examples

1. Verifying Video Stream Specifications

Video Editor

Background

A video editor needs to confirm that an exported MP4 file meets the client's strict delivery specifications for video codec, frame rate, and audio channels.

Problem

Manually checking file properties in the OS file explorer does not show detailed stream-level metadata.

How to use

Upload the exported MP4 video file to the Media Metadata to JSON tool.

Outcome

The tool outputs a JSON file detailing the H.264 video codec, AAC audio streams, exact frame rate, and channel layout.

2. Extracting Podcast Chapter Markers

Podcast Producer

Background

A producer wants to verify that the chapter markers and ID3 tags were correctly embedded in their final MP3 episode.

Problem

Checking chapters requires specialized playback software or command-line tools.

How to use

Upload the MP3 podcast file into the media file input.

Outcome

The tool generates a JSON structure containing the chapters array and tags object, confirming all timestamps and titles are correct.
