Video render with matinee

Hey guys !
I would like to make a video render of my architectural simulation. I used the tools matinee, I put my keys on my CameraActor, but I can not render, when I click on Movie I start the rendering but it does not take into account my CameraActor , Because for rendering Unreal closes the Matinee window and my keys are no longer taken into account.
I assumed that it is because there is no trigger, does it necessarily require a trigger to switch on the CameraActor? Like a colision box for a kinematics launch, etc?
I have no other camera in my scene.

Thank !
