Animation exports

When I export a .blend into another type of file, sat .3ds or .x, will the animation stay with it? Or will it just be the 1st frame that is exported?

If it is just the first frame then I cant really use it for what im planning and instead of all this low poly nonsense I can just make high detail models and make films with them.

3ds exporter for blender I think doesn’t support animation, only models. .x supports animation.
