You can scale nCache clips to speed up or slow down your object’s cached simulation.
Scaling down (<100% of the original cache clip length) a cache clip compresses the simulation in the cache clip so that the resulting simulation appears faster or sped up. Scaling up (>100% original cache clip length) a cache clip stretches the cache clip’s simulation so that the resulting simulation appears to be slower.
All the current object’s caches appear as clips in the track view.
