Help with Open Broadcaster Software - Dwarf Fortress

Hey Day[9] Community,

I'm trying to use Open Broadcaster to record me playing Dwarf Fortress, but I've hit a problem DFers will understand.

The "Game Capture" doesn't seem to be working - just a black screen. So I tried monitor and window capture instead. However, either: DF is a really small window (the one it launches as) OR I can make it fullscreen, but that's too large to fit into OBS apparently.

So, how can I use OBS to record me playing DF?

Game capture isn't working, fullscreen is too large, and the default size is way too small. I can't set screen region because I would have to make the DF window exactly the same size every time.

Can anyone help?
