It's hard to tell from the video, but usually tiny buckshot type holes indicate flea beetles. I fight them on my tomatoes, and they especially love eggplant. Look for teeny tiny bronze bugs that jump like fleas. They can be on the top side or underside of the leaves.
Although the link is from the colorado state university extension, it has good pictures and good information.

That is exactly what I have, funny how things pop out, when you know what to look for!
Seems like the super sweet 100's are acting as a "trap crop" for them, and saving my beefsteak tomatos right next to them.
