Not being rude but it looks like one of those UFO sighting videos. That fluid could a myriad a things and a solid couple of photos would help us not waste your time and get your Jeep up and running.
Also, did you see this while the Jeep was sitting, after driving the Jeep, what does the fluid smell like, & are you throwing a CEL?

Pretty typical of the 4.0 engines in our Wranglers. These things are notorious for leaking rear main seals. In fact, it's so common that most of us just get used to it. Unless you have puddles of oil underneath the vehicle, it's nothing to worry about, just fix it when you get time and money.
However, if it's leaking huge puddles, then you'll want to fix it ASAP. If you feel like taking on the rear main seal yourself, there's a how-to guide here: Rear Main Seal Replacement (4.0)
However, if you pay a mechanic to do it, it's probably a 3-4 hour job and would likely cost anywhere from $300 to $600 depending on the mechanic.
I have no check engine light, it was strange. This is my first jeep, and I was at school and it was right after I parked and shut my car off that I saw like almost a droplet forming on the transmission, but after my class I came back and it looked perfectly dry and fine. I will take better pictures. It doesn't really smell like anything
And the jeep runs and drives fine I just saw this today and would like to address it before it becomes a big deal
Mine " rear main " has leaked a drop here and there for almost a year.
It will likely leak here and there for the up coming year.
If it something you can't live with then follow the guide provided by Chris.

My 95 XJ always had some oil leaking from the rear main oil seal. No puddles or large amounts, just a couple of drops. I ran like that for tens of thousands of miles, never replaced the rear main and ended up selling it when I bought my TJ. Most of our Jeeps leak a little fluid from several sources. The questions to ask yourself are where is it coming from, is it enough to cause any damage, can you stay on top of it and is it worth spending the time and money getting it repaired? Most older TJ's have over 100k on them and small leaks are common.
Great point. I had this problem and had a hard time identifying the cause of the leak. Replaced stock gasket with a FELPRO and solved that leak issue.
