Brightness/contrast multiple frame adjustment

[Speedgrapher]

I'm trying to create an animated gif, some 20 frames in length-- but I know how to do that much. What I want to do is change the brightness and contrast in unison for them.

That said, I tried using that ridiculous help option in the program that reads like latin.
This is what I think it said about it:
* The unify buttons determine how the changes you make to a layer in the active state or frame apply to the other states in a rollover or frames in an animation. When a unify button is selected, changes apply to all states and frames; when a button is deselected, changes apply to only the active state or frame.
* The Layer > Match command lets you apply the layer attributes for an existing state or frame to other states in a rollover and frames in an animation.

WHAT? I tried turning on the features before and after the frame adjustment, same for the "match" option. All it does is either replace every frame with the current one, or just manipulates the one itself.

In short-- 20 frames-- all I want to do is pick them all at the same time, and use the exact same setting for the bri/con. (Oh, and simply selecting them all just turns OFF the feature.) I don't want to have to adjust each and every single one separately.

It is quite straight forward - The unify buttons determine how the changes you make to a layer in the active state or frame apply to the other states in a rollover or frames in ................
I see what you mean, now I am losing the will to live!

Take a step back for a moment, you have a 20 frame animation, are they frames or layers? Are they variations of each other?
Brightness is easy to achieve, a white layer at 100% = zero brightness, 0%=full brightness.

Well, here's the thing. Its 20 layers and 20 frames, and yes, each one of them is slightly different. All I want to do is change the brightness and contrast to bring out more vibrancy in the art equally.
