How do you do this cool sh:t...?

How do you make it so like in a cinemetic or sumtin that all the units animes just freeze and stay at what they where doin???

you know like if a bloodmage did a lame spin anime like he does how do you make it so he stops and freeze like half way :D

Im pretty sure just selecting all units in the cinematic will pause them in there current animation

Setting their animation speed to 0% works.
