Prolost Burns comes with default settings that zoom a layer from 100% to 150%. You may wish to create your own settings and paste them into multiple layers. Here's how.

The Easy Way

Just apply Prolost Burns to multiple layers, then copy/paste the effect from one to the next.

To add Burns to multiple layers at once, select the layers and double-click on Prolost Burns in the Effects & Presets panel.

If you modify the Prolost Burns settings on one layer and want to copy those changes to other layers, do this:

Select the Prolost Burns effect on the layer that you’ve modified. Make sure the effect itself and only the effect is selected.
Copy the effect with ⌘ + C on Mac or Control + C on Windows.
In the Timeline, select any layers that already have Burns applied, that you’d like to have the new settings.
Paste with ⌘ + V (Mac) or Control + V (Win).

This works because the layers you’re pasting to already have Prolost Burns applied. If you want to paste Burns to layers that don’t already have it, or if you want to save a preset of your custom settings, read on.

The Hard Way

Prolost Burns uses expressions to control a layer’s Scale, Position, Anchor Point, and Opacity. The preset contains an empty “effect” that holds the controls that drive the expressions. When you copy this effect from one layer and paste it to another—as you would any other effect—you’re copying the controls, but not the expressions. It’s like copying the dashboard of a car without the engine.

To copy and paste everything Burns needs to work, select the layer in the Timeline and press the U key twice, rapidly. This is known as the “Über Key” in After Effects, and it reveals all of a layer’s parameters that have been changed from their defaults. In the case of Prolost Burns, it will reveal the effect as well as the layer’s Scale, Position, Anchor Point, and Opacity.

Select all of these parameters in the timeline, by clicking on their names with the Shift key held down.

Now you can copy, and paste the results into a new layer. The Prolost Burns effect, and the expressions, will paste into the new layer or layers.

You can also save an Animation Preset with this selection, and apply it to fresh layers just like you do Burns.

This technique also works for Prolost Boardo and the Prolost EDC presets.
