How Can I Control an Emissive Video Material?

[Unediense]

Hi, I’m a beginner. I created a “Material In Unreal Engine 5 (Media Texture)” video. In the video, it explains how to make the material emissive, but now I don’t know how to reduce the emissiveness. I double-clicked the material, and in the lower-left “Details” panel, I don’t see anything labeled “Emissive.” I don’t know where I can reduce it so it’s not so bright.

Hi, i Created this node ‘multiply’

But despite of the fact of reducing the value to 0,08, it keeps on being too emissive and bright. Maybe with media texture it doesn’t work (?)
