DeVeDe is a free and open source DVD and CD authoring utility. DeVeDe produces disk images ready for authoring to CD or DVD, and allows to burn them to CD/DVD discs. The source material may be in any of a number of audio and video formats, and DeVeDe automatically converts the material to formats compatible with audio CD and video DVD standards, as used by CD and DVD player devices. DeVeDe uses other software packages, including MPlayer, MEncoder/ FFmpeg, DVDAuthor, VCDImager and mkisofs, to perform the format conversions, and can use K3b or Brasero to burn an ISO image on Ubuntu, or a variety of other software on Windows.
DeVeDe can handle source material in many popular video file formats, including .avi, .mp4, .mpg, and .mkv.
