Stance change frames?

Hi, since SF 5 moves are measured in frames, I was wondering if anyone knew how much time or how many frames does it take to switch stand positions? For example how many frames does it take to go from a standing position to a crouching position? Or from a crouching down back position to a crouching down forward position etc?

There is no such thing as a startup for crouching or standing up. It happens as soon as you press the direction on your d-pad or stick.

So it’s instantaneous then?

Yes
