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?
a Gravitational-Time dilated place to somewhere far which is not dilated
"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?
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)
Yes they would. In fact, you can interpret cosmological observations we now do as precisely this phenomenon, only backward-- we are looking from a less dilated place to more dilated places, and they appear to be moving slowly as a result. For example, cosmologically distant supernovae seem to play out in slow motion as we watch them. So to have a situation as in your question, we only would have needed a universe that is contracting instead of expanding, and we'd be seeing things playing out in fast motion at large distance.
Note this general relativistic effect, which appears at order (v/c)^2 where v is a measure of the strength of gravity in velocity units (similar to an escape speed, for example), is not to be confused with a time-of-flight effect, which appears to order (v/c) for some actual v, and also can make things appear like they are moving fast or slow depending on the sign of v. For example, if you drive toward a drive-in movie screen, the movie will appear to play out slightly faster, but this is just a time-of-flight effect and would happen for a sound concert as well. It is also not to be confused with the special relativistic effect of time dilation, which always makes everything else outside of you appear to play out slower than it would have otherwise, regardless of whether it is moving toward you or away from you. The general relativistic effect is a gravity effect, and cosmological effects can be interpreted similarly to gravity effects as the gravity of the universe as a while evolves.
