Reducing Keyframes?

[Rodney]

I'm trying to refresh my memory.

I know that if we select a channel we have the option (via Right Click) to 'Reduce' keyframes.

This however isn't practical when there are a whole lot of channels to reduce.

 

I will guess the best way to proceed might be to Bake Action and then increase the Tolerance setting.

 

Is that correct or am I wondering off in the wrong direction?

I have sometimes wished there was a way reduce more than one channel at a time.

 

Do you have an example case?

Here might be an example...

 

A project consists of one Sphere and two Actions.

The first Action controls up/down motion.

The second Action controls distance traveled.

The Sphere is placed In the Chor.

Both Actions are dropped onto the Sphere (and made to overlap... because the second will generally follow after the first when drag/dropped).

Both Blend modes are then set to Add.

For fun have the up/down Action repeat three or four times.

The entire animation occurs over 1 second (or 3 seconds if preferred).

The Chor Action is baked.

The resulting Baked Action is exported as an Action.

Now the Action can be brought back in and used as the basis for more complex and layered action.

But...

Before proceeding a pass needs to be made to simplify the new Action because it contains too many keyframes and lacks optimized hard and smooth transitions.

 

That's a basic Bouncing Ball setup that initiates from a series of simple overloaded Actions where it would be nice to reduce, round or average the values in all of the resulting channels and... to limit the number of keyframes for easier editing.
