How it works

  1. Upload a video.
  2. Set exposure in EV stops (−2 to +2), or use presets.
  3. Optional: Show exposure preview for a live look.
  4. Click Apply & Export, then download the WebM.

Note: +1 EV ≈ double light (brighter); −1 EV ≈ half light (darker). Implemented via brightness + light contrast for a natural look.
