How to create and how much does a teaser video for a PC game cost?

Question

Video

I would like to create a teaser for the upcoming game. I really like the similarity of TES6

Of course, there is a very large scale here, but I would like to make a bird fly over the forest and a sharp transition to an ancient castle on fire. Then the credits and the release date. How to do this? Is it necessary to model the scene and make a camera span? Or other ways?

Answer 1

As you want - so do it. You can at least make a teaser with live actors.

Is it necessary to model the scene and make a camera span?

If it's easier for you, then do it.

Or other ways?

Well, you can take a live bird or a drone, shoot a flight and then edit the video to make it more fantasy, if that suits you.

Answer 2

Start creating a game. Not a teaser. Then it will be clear what and how to do.

Answer 3

Capture a screen with a disabled game interface with a free camera, pre-registering the route / speed of the camera.
