Questions for timestep schduling

[Emersonksc]

"I am new at this and wonder why you added timestep scheduling for animate-diff. I think the motion scale and effect for timestep scheduling is like a black box. Without documentation showing how it influences our generated videos and experiences, most people hardly use it. Maybe I'm wrong, I just want to know how you use it:)"
If there is a sweet spot that makes animate-diff motion and lights better, I would like to know it
Latent frame scheduling is more straightforward, it can change the motion and light in different frames:). Would you add it?
