This will depend on your Strip setup. But usually this should be pretty similar to the particle system. If you decrease the lifetime of your particles, your trail should be shorter. The length of your trail as for the particle system is often dependent on your particle’s speed and lifetime.

A section of this sample is dedicated to strips and the different method to create them. I hope this will help you. Wish you a sunny day.
