Play Local Video Online – Privacy-Focused Browser Player
Drop any video file from your computer to play it instantly in the browser. Test local file compatibility, check video metadata, and monitor playback performance. Files are processed 100% locally.
How VideoLab Works
Three steps to test and debug any video stream
Paste a URL or Upload a File
Enter any MP4, M3U8, MPD, YouTube, or Vimeo URL — or drag & drop a local video file directly into the player.
Hit Play & Watch Diagnostics Update Live
The player starts streaming instantly. The debug panel tracks connection status, resolution, bitrate, codec, and every network event in real time.
Share or Export Your Debug Log
Generate a shareable URL to reproduce the exact test, or export a full JSON debug log with timestamps, errors, and stream info.
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.
