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.

Private Local Video Playback

Unlike other online video players, VideoLab doesn't upload your files. We use a local blob URL to stream the file directly from your hard drive to the video element. This ensures maximum privacy and zero data usage for large video files.

Testing Codec Support

Use this tool to quickly verify if a specific video codec or container is supported by the browser you're currently using. The debug panel will show any decoding errors or metadata issues immediately.
