well then you'd need fraps or camstudio or something, it'd be nice if a mod could be made specifically for timelapses. That'd be a lot easier.
You don't need to record video for time lapses, you just need to take pictures every few minutes. I think it'd be a lot more practical to take pictures every few minutes with a mod than to use fraps (wich the demo only works for 30 seconds) or camstudio (which is low quality.)
Speeding it up would work too, but you really don't need to. If you just take one picture every few minutes and then put it all together at like- 15 frames per second, you have a good time lapse.
I'd really appreciate it myself if someone made this, I don't have thirty dollars for fraps, camstudio kind of stinks, and I don't want to manually take pictures every minute or so. That'd just be really tedious
