FrameForge 4 provides a tool called "tweening" that allows you to create stop-motion animation without having to manually set up and snap each individual shot.
1. For an animation, you need to include some in-be tween frames be tween the setup in Key Frame 1 and the setup in Key Frame 2. Those additional frames are "tweens."
2. Rather than forcing you to set up and snapping each of those tween frames individually, FrameForge can generate them automatically, saving you a lot of time and effort. You can view them as a slide show or in a movie file.
