In the movie Interstellar, Miller's planet is depicted as a planet orbiting very close to a supermassive black hole called Gargantua. Due to the extreme gravitational field near the black hole, time dilation effects would be significant. As a result, the camera feed from Miller's planet to Romilly on the spacecraft Endurance would experience substantial time dilation compared to Romilly's time.
From Romilly's perspective, watching the camera feed from Miller's planet, he would observe time passing much more slowly on the planet's surface. This means that the events captured by the camera, including the movement of individuals or objects, would appear to occur in slow motion. A minute on Miller's planet might correspond to hours or even days from Romilly's perspective.
This time dilation effect is a consequence of the strong gravitational field near the black hole, and it is an accurate representation of the time dilation predicted by general relativity.
