“This Is Eve” is real in-game footage
I believe the comment under the “This Is Eve” video says “Yes, the ships and scenes are rendered rather than actual in-game footage.” is incorrect. The visuals look like in-game graphics, not a version rendered separately from the game itself. You can make similar shots in the game yourself with the provided cinematic camera.
There may be some post-processing, but the video is shot in-game.
