It isn't. Apple's Screen Sharing and Remote Desktop offer no provisions for connecting to Macs on other networks. In order to connect to Macs using these tools, one either needs to manually open ports on their router or establish a VPN connection into the network where the remote Mac is located. Additionally the user needs to know the IP address or domain name of the remote Mac. Tools like TeamViewer, Jump Desktop, and Screens can all automatically configure this and don't require the user to reconfigure their networks to use them.It is.

I do video editing, so I need something with low latency. Which one would be the best?
Jump Desktop has the lowest latency of any that I've tried, and can pass through audio, but I'm not convinced it'll be fast enough to do remote video editing.
None of these are good enough for video editing. I wouldn't even attempt to edit video over a direct Ethernet connection with two computers sitting right next to each other on the same network.
I suspect you’re gonna need to modify your goals
Precision mouse movements over any sort of remote connection, are going to have latency. That’s going to REALLY slow down editing, even “rough cuts”. Try a couple of the free solutions, if they seem even AT ALL close to what you need then you can look at the paid options to smooth it out a “little bit.” But if the free solutions slow you down as much as I expect they will - paid ain’t gonna change that enough to matter.
