If I could see from a Gravitational-Time dilated place to somewhere far which is not dilated, would I see fast moving people? Gravitational time dilation like the one shown in the movie Interstellar, causes time to move slowly for someone within the high gravity reference frame. Now let's say that from such a place, I was able to view through a telescope somewhere far away which is not gravitationally dilated. And assume that I am able to view the near live video stream of it. Would those people look fast moving?

"Dilated" or "not dilated" are not absolutes. It's always a relative thing. "Dilated" relative to me, but perhaps "not dilated" relative to you. There is no dilation that happens "in general"; it's always relative to another place/observer/reference.


  Would those people look fast moving?


Yes.

Now, everything coming out of that place would seem like it's "speeding up time" relative to you. If you're looking at them through a telescope, all light would be blue-shifted. If you're receiving a TV transmission, the frequency of the carrier would also be higher.

Keep in mind, this time dilation is not an illusion. It's not just "how you see things". Their flow of time, as measured by you, is indeed faster. This affects everything in that place, as measured by you.

But it's also relative. Some other observer may be in a place where time flows differently from yours - they would look through the telescope and would see a different rate of change. And it's not an illusion for them either.

Time dilation is real. What's not real is a unique time, ticking the same for everyone - that's the actual illusion.

Time is a local thing. (more precisely, the rate of ticking for a clock is a local thing)
