Change Visual Effects When entering a battle?

I have read most posts here and the game's help but can not find the settings or ways of visual effects, like Screen Fade in/Out, Broken Screen, ...etc. that are used when actors initially enter a combat. Somehow I remember there is an easy setting to change the effects. However, I have failed to know where it is and how to change the effects with built-in function.

Secondly, is there any way to change the actor's "reaction animation" right after the actor is attacted? For example, show an emotion icon above the actor's head.

Thanks for any ideas and help.
