What is it?

A modern and user-friendly web interface that helps you easily prepare the MP4Muxer command used to create Dolby Vision-enabled MP4 files from UHD Blu-ray sources.

  • Multilingual Support: Interface available in Turkish and English. Users can switch languages with the flag icons at the top right.
  • User-Friendly Interface: Modern design, descriptive labels, tooltips, and error messages enhance user experience.
