History: ROQ

Historically, ROQ was the only video format supported by Doom 3 and TDM. All the missions created before TDM 2.06 use ROQ format for their briefings. The ROQ is rather old and weird, and it is not supported by most software. That's why it is considered a "legacy" option now.

Common formats

Since 2.06, most of the video formats can be used in TDM directly. In order to achieve it, specify the path to your video file in the videoMap keyword of the material definition (just as usual).

You can encode the video with any codec supported by the libavcodec/FFmpeg (see the approximate list). But please be wise in codec choice: better use common and widespread codecs with default options. Codecs XVID and x264 are good examples here.


Although FFmpeg supports many different containers, TDM can only play a limited set of them from inside a pk4 file. If you use wrong type of container, then TDM would generate a warning "Opening video file "%s", which is compressed inside PK4", and the video will not play properly.

IMPORTANT: Use mp4/m4v or avi containers for video files!
