Could it be the timing belt?

Alright so In the last week my car has been basicly turning into a POS...
Here are the few problems I can think of that its having right now...

-Ticking/knocking
-The practically stalling when trying to take off, Like for example I'll be at a stoplight and try to go It'll have power for like a second then it'll like stall without turning off.
-While it does that it makes popping noises under the hood.
-Last night I was going about 80 when my car decided to start like studdering and started poping/knocking, I took it out of gear and coasted for a minute and put it back in and it seemed to be fine
-Its starting to shake while idling

Heres a small video of under the hood while idling

Any ideas of what these problems could relate to?

I don't think it could be the timing belt, because that engine doesn't have one. It has a chain. Probably not that either, unless the car has lots of miles on it. I would rather think it would be something electrical.
