Superman intro echo problem

Hello

How do I make the echo animation slowe just like the Superman intro from 1978?

You create your artwork, animate the position in Z or scale, pre-compose, then apply the echo effect to the pre-comp and adjust the parameters. Making the layer 3D and animating the Z position will give you the best look.

I suggest that you type Echo Effect in the Search Help field and check out the community resources for details on how to use the effect. It takes a bit of fiddling around to get the look you want and the adjustments for this kind of effect are very small.

Thank you Rick!

Sorry for stupid question but I've only got one layer isnt pre-comp for multiple layers?

Pre-composing structures the AE render pipeline and doesn't just serve as a means of grouping items. Effects like Echo may require pre-composing since they require multiple pixel buffers to be accumulated and pre-composing your animation does just that. It's basically like the effect saying "What does the rendered/ flattened result look like on frame X? Can I have it please?!" as opposed to requesting native transform values or some such thing.
