> you need to worry about other things

Serial I/O is common Hello World example for Raspberry Pi. I think you have to worry about less things than adhoc wifi networks.

> likely much slower

It's slower, but not much slower. The baud rate can be set up to 4,000,000, where a megabyte would transfer in 2 seconds. These "gifs" don't seem to be more than 10 seconds long, so they should be less than 1 MB, judging from random Giphy mp4s.




Is common yes but not as easy you can't easily setup file transfer over serial, in this case a simple FTP to a pre determined folder that the screen grabs the gifs from is a heck of a lot easier to setup than sending a binary file over serial.
