How to perform a high jump?

What’s the timing when doing high-jumps? I know you hold down and then up as soon as possible, but I would like to know what is the precise second/timing when doing high-jumps and high-jump cancels.

What game?

Airdashers, like guilty gear and blazblue. Sorry for not being clear.

In BB you can perform a high jump by quickly pressing down and then up on the stick/pad. It also works for other games, like UMvC3 and Skullgirls.

Is there any timing involved when performing High-Jumps or do you just do them quickly as possible??

I don’t know the exact input window for the high jump to come out, but just like anything else, you go into training mode and practice it until you can do with with muscle memory. Just practice doing jump-ins starting with a high jump or something.

No idea, but it’s not hard. At least I don’t remember struggling with super jumps in any game I’ve played.
