Best tool for upscaling lots of long videos?

I want to upscale and generally improve a bunch of old family films. What tools should I consider? it's probably close to 100 films, each between 1 and 2 hours long.

I prefer free options, but I don't mind paying if it's a reasonable pricing model.

Bonus points if I can extract meta-data such as scenes, scenarios and facial recognition to help me categorize it
