Thanks for clarifying the issue you are experiencing.
Mehmet’s answer from a few days ago is the correct one for this. To control the exposure as seen in Matinee’s “Create Movie”, you need to set the exposure directly on the CameraActor that is being viewed through, under it’s Eye Adaptation category in the Details panel.
When you set the exposure in the Editor’s “View Mode” dropdown, this is only for your own benefit as you work in the editor.
I hope that helps.
Cheers!
