You can see the dmx channel of the video player in our reference manual http://www.capture.se/Manual/2020/appendix.html section 17.1.3, but there is no control over the intensity of the video player. If your intention is to have dmx control over the result of a video player then you can do that from the properties of the material that you have connected the video player to. This property is the texture generator and upon configuring it you can choose the mode named "dimmer", and then patch it in one of your dmx universes that are controlled by your controller.

Thank you! I have done it.  Sorry, but after selecting a video player in texture media, the dimmer function in texture generator does not work.  I do not understand.  The address is set and the dimmer is controlled from console.  Explain what I'm doing wrong?

In an attempt to reproduce it indeed it is not possible and it has been filled as a request. Your alternative is to use a media server if you need to control the intensity of the video content. Sorry for the inconvenience.

Thank you so much! Sorry if I didn’t understand the previous answer.
