Processing Steps

  1. 1. Drop .MP4 Files Locally
    Choose MP4 (video/mp4) files from your device. The browser checks their type before processing.
  2. 2. Summarize Locally
    Create a metadata or telemetry report about the video.
  3. 3. Save .XML or Swing P2P
    Download the .xml output, export a batch ZIP, or choose "Convert & Swing" to transfer it to another device.

Frequently Asked Questions

What does this MP4 to XML route produce?

Create a metadata or telemetry report about the video. The output is a derived view; it does not preserve the complete source file.

Does the .mp4 file leave my device?

The conversion runs in your browser. Files are not uploaded to a conversion server.

Can I process large .mp4 files or batches?

There is no daily conversion quota. Large files and batch size depend on available browser memory and the format engine.
