How VideoLab Works

Three steps to test and debug any video stream

Paste a URL or Upload a File

Drop a link or drag a file right into the player. We'll detect the format and start loading the video.

Watch Diagnostics Update Live

As the video plays, the debug panel tracks the connection status, resolution, bitrate, and network events as they happen.

Share or Export Your Logs

Generate a shareable URL to let someone else see your exact test environment, or download a JSON debug log to review later.

MPEG-DASH Explained

MPEG-DASH is the international standard for adaptive bitrate streaming. It segments video into small chunks described by an XML manifest (MPD). dash.js adapts quality in real-time based on your measured bandwidth.
