Frequently Asked Questions
Any questions? GDTF is here to help.

The General Device Type Format (GDTF) creates a unified data exchange definition for the operation of intelligent luminaires, such as moving lights. By creating a manufacturer-supported, unified standard, customers/users of lighting control systems, CAD systems, and pre-visualizers benefit by knowing the tools they use to perform their job will work consistently and dependably. The file format is developed using open-source formats, and luminaire manufacturers in the entertainment design, production, and performance industries are welcome to use this open-source technology.

My Virtual Rig (MVR) is the container file that holds all information about a scene or stage. It includes GDTF data, patch information, location of objects, and really everything you need for an event. You can think of MVR like the truck that takes all the gear to the venue.

GDTF was originally conceived and jointly developed by the GDTF development group, comprised of Vectorworks, MA Lighting, and ROBE Lighting. This development group currently is responsible for any GDTF maintenance. Additionally, manufacturers that have adopted the format or are working on implementing it are also involved in providing feedback for the future development of GDTF. The GDTF-share is hosted by the German Entertainment Technology Association known as VPLT.

We host a monthly manufacturer meeting for all manufacturers to get together and ask questions, raise concerns, and stay updated. Send us an email with the Contact Form to get on the invite list. In between meetings, you can also get involved with the community through GDTF-Share, the fixture builder, the GDTF Forum, and the GDTF GitHub page.

Additional details are available on the GDTF GitHub page.

Currently, ChamSys, GrandMA3 and Martin P3 System Controller can read and/or export GDTF files.

Currently, Vectorworks, MA Lighting, CAST Software, Capture Visualization, ChamSys, Syncronorm and Martin P3 System Controller support MVR files.

Information on how to support MVR files can be found here.

Yes. In 2022 it was updated to DIN SPEC 15800:2022. The current version supports lighting devices, media servers, and rigging items like truss and hoist. Future planned improvements include video projectors and audio equipment like speakers.

Yes. GDTF is defined within the DIN SPEC 15800:2022.

No. The GDTF format is adopted by a variety of manufacturers. There are new GDTF files in the GDTF-Share every day and there are multiple manufacturers who can read GDTF and/or MVR files in their applications. You can see a full list of manufacturers working to support GDTF here.

Look for the GDTF file icon, consult this website for a list of companies that support the file format, and check the GDTF Share or contact the manufacturer directly. If a manufacturer does not currently support the file format and you'd like them to participate, contact the manufacturer directly and ask them about it.

Absolutely. You can use the GDTF Builder to create a GDTF file yourself. To help you get started, we have been publishing training materials on our GDTF & MVR channel on YouTube. For any questions, feel free to use the GDTF Forum.
