The goal of DuME is to be as easy to use as possible even for beginners, without any compromise on functionnality for advanced users.

To achieve this goal, the development of the application follows these guidelines:

  • The User Interface has to be both intuitive and nice-looking, as well as fast.
  • Transcoding to standard formats (mp4, PNG…) is straightforward, thanks to carefully crafted presets.
  • The most common parameters (resolution, frames per second, codec, quality…) can easily be set through the user interface
  • Advanced users can add any other parameter available in FFmpeg thanks to the “custom parameters”, or even input their own commands through the included command line.
  • Common parameters and Custom parameters can be saved as easy-to-use User Presets.

Available Features

  • Transcode any audio or video file, from any format supported by FFmpeg to any other format supported by FFmpeg.
  • Easy presets for: mp4, wav, PNG, EXR, Quicktime HAP, GIF… - evolving list.
  • Transcode to and from Image Sequences (PNG, EXR…).
  • Mix Media files (e.g. add sound to an image sequence).
  • Easily render After Effects projects and transcode to any format supported by FFmpeg.
  • Render/Transcode queue, work in progress, possible with command/batch files thanks to the command line interface.

Planned Features

  • Simple media player (using ffplay).
    • Preview of the input.
    • Preview of the output.
  • Render Blender scenes.
  • Append several inputs.
  • Add subtitles tracks.
  • Burn subtitles in picture.
  • Burn Metadata in picture (Timecode…).
