# Best way to achieve scales orders of magnitude bigger

Hey everyone,

Im a pretty new AE user, and i have been interested in creating videos which compare sizes and magnitudes of various things in the universe. For example, comparing the speeds of the universe, from a snail all the way to light speed, by giving faster things a bigger size. I have been creating the effect by making various 2D composition cards of each item which is being compared, eg;

I then created a camera and made the layers 3D, so i could zoom out of each composition card to show the relative sizes and have the cards sitting at a nice perspective which looks cool. eg;

Hopefully you understand what I'm trying to achieve.

The problem I keep running into is that I'm giving each card a scale based on it speed to get the relative sizes when I zoom out. The scales begin to get out of hand, because on the one end i have speeds of 40km/h, and by the end of the video im dealing with the speed of light which is around 1,000,000,000km/h and after effects starts glitching out long before i set the scale to millions of %.

I have tried stopping the video, creating a new composition and trying to reset the scales again but i can never get a seamless transition from the previous one.

I am wondering if anyone on here could help me out or show me a method to achieve the same effect but be able to deal with the cards being millions if not billions of times bigger than each other at times.

If i haven't explained something clearly please let me know, and all feedback is appreciated

Thanks alot!

There is no magic recipe here. Your approach is already pretty much what anyone would use. the only real issue I see is that you don't seem to be aware of the collapse transformations option to create a chain of nested 3D comps that retain their properties...

Thanks for the response.

Collapsing transformations seems to be the way forward, hopefully ill be able to finish my video... ill post it here if It works!

I take it that you want to continuously expand the red line while the text changes. If that is the case I'd put some kind of color gradient in the line or change it in some other way so that it looks like the line is growing at the correct rate. there were red and blue dashes that indicated something like 10 kilometers as they moved closer together the line would change to purple. Then if every 100 kilometers was another two colors when you got to 1000 km another color would appear. This would give you some sense of the scale changes. Just making a solid red line longer isn't going to tell you much without some kind of scale indicator.

No the red line remains under each card, and the camera zooms out to reveal larger items... here is another video i made which was small enough to not have the scale issue
