Is it possible to slow down an animation?

Hey all I have 0 skills in animation but I was wondering if it is possible to edit an animation in Unreal Engine 4 to slow it down. Like lets say my guy is swinging his sword really fast frames 20-30 and I want it to go from like 20-50 instead. Is this possible? (I tried inserting a frame but that kinda just makes my guy stop his motion completely which isn’t what i’m going for.)

Change the play rate scale.

In a statimachine, Click the animation, look at the details panel. You can probably expose the play rate scale if you need to control it programmatically.

Changing it directly on the animation will affect every instance of the animation.

Afaik if you want 100% control of animation speed, pause, reverse, look into Animation Montage.
