If we're able to identify the position once of a quantum particle, would it not then be feasible to time a ton of pictures to happen at nearly the same nanosecond on the same quantum particle to track it's 'position'?

1) Why is it not possible to measure the position of a single quantum particle multiple times? (aka a video) Would we be able to then track it's momentum?
2) If the answer to the above is that it pops in and out of existence, how exactly does that happen?
3) How large of a field would you need to track a single quantum particle?
4) Would that be able to be done on Earth? Would we have to develop a large science facility in space somehwere? 
5) Would it even be possible to build a machine large/small enough to do this?

We **can** detect the position of a particle multiple times.

>Would we be able to then track it's momentum?

Yes, although this does not allow for violations of the uncertainty principle. And anyway the product of the experimental uncertainties on the position and momentum will be much larger than the Heisenberg uncertainty lower limit anyway.

>If the answer to the above is that it pops in and out of existence, how exactly does that happen?

It's not the answer to the above. It doesn't really make sense to consider a real particle popping in and out of existence.

>How large of a field would you need to track a single quantum particle?

Particle detectors in experimental particle and nuclear physics come in various sizes. Some can fit in your hand, and some are huge arrays of many detectors, much larger than a human body.

>Would that be able to be done on Earth? Would we have to develop a large science facility in space somewhere?

There's no need to be in space, unless you're specifically interested in particles of extraterrestrial origin. Even then sometimes you can detect them from the ground.
