Camera Anim - how to export from 3ds max or maya?

Hi guys,

On this video Making Robo Recall Cinematics with Sequencer | GDC 2017 | Unreal Engine - YouTube Wes mentions that you can import a Camera Anim class from your favorite 3d software, such as 3ds max or maya.

I searched the internet up and down and couldn’t find an explanation on how to do that. Does anyone here know anything about this? Maybe someone from Epic could clarify?
