Run multiple instances at once?

[Pcenginefx]

Hiya - been using Video2x for a few weeks on a sequence of still frames and was wondering if it was possible to have multiple instances running at once on the same PC? I tried this and it errors out as I think both instances were trying to use the same temp dir/file (?). I'd love to get this to work to speed up the process since my PC is pretty beefy and could handle more instances running at once. Thanks!
