Long exposure Astrophotography video possibility

I have a photo of a car in the middle of the road at night and it's long exposure so you can see the whole galaxy behind it, I want to make it a video though where the camera starts looking at the ground and then slowly pans up to the car and galaxy in the background but i cant shoot a long exposure video on iphone so the video just looks dark and the sky is black instead of seeing the galaxy.

Is there another way to do this or do I need to use an actual camera with good low light video? My other idea was recording a video and then stitching it together with the photo but the lightning wouldn't match.

How do you all light your subject naturally for low light long exposure photos?
