System Requirements

⚠️ IMPORTANT: This tool requires a GPU with Vulkan API support

Compatible Graphics Cards:

NVIDIA GPUs

  • GTX 600 Series and Newer (Kepler architecture and above)
    • Examples: GTX 680, GTX 970M, GTX 940M
  • RTX Series with full Vulkan 1.3 support
    • Example: RTX 2060

AMD GPUs

  • Radeon HD 7000 Series and Newer (Graphics Core Next 1.0 architecture and above)
  • RX 500 Series recommended for open-source driver support
    • Examples: RX 570, RX 580

Features

  • Drag and Drop Input
    Quickly drag your .mp4 or .mkv file into the app (or choose the input / outputs via the browse buttons).

  • Dolby Vision → HDR10 / SDR / HLG
    Converts Dolby Vision files into three possible color spaces:

    • HDR10
    • SDR
    • HLG
    • Standard

Please note that h.264 support for dynamic range color options is quite limited and may not work on some of the devices such as TVs.
Please select "Standard" option for the most compatible color output option.

  • Quality & Size Control via Bitrate
    Adjust the average bitrate (e.g., 15,000 kbps) to balance file size and video quality.

  • Codec Options: H.264 / H.265
    Choose between libx264 (H.264) or libx265 (H.265) for transcoding.

  • Automatic Output Naming
    The output file keeps the original name, appending _converted (plus extra details) at the end.

    • If no output folder is selected, it defaults to the same folder as your input.

How It Works

  • Transcoding & Color Filters
    Internally, I use FFmpeg with hardware-accelerated color filters (libplacebo) to decode Dolby Vision data, apply the correct tone mapping, and re-encode into your chosen color space.

    • The process re-encodes each frame, so expect some generation time, depending on your CPU/GPU performance and bitrate choice.

  • Preserve Audio & Subtitles
    Audio and subtitle tracks are copied directly, so you won’t lose any of your original streams.

Feel free to report any bugs or suggestions in the Issues tab.

To install download the zip files for your version of Windows, or use installer exe files to install the program on your system.
