Good looking post processing used to be exclusively reserved for movie studios with render farms. Then it became available to any YouTuber with a PC and a license (or not) of Adobe. Now the average phone can do more impressive special effects for Snapchat filters than big budget movies had not long ago.

I'm convinced that deepfakes will be as easily generated as a Snapchat filter within a few years, substantially less time than society will require to adjust to this reality.

There was a viral video last week of the "Ghost of Kiev" that looked like real war footage. It ended up being from a 2013 video game!

Post processing or just lowering the resolution?

Filming a deepfake with a DV cam pointed at your screen is very convincing. Sadly.
