How to increase composition time?

Question

Adobe After Effects

How to increase the composition time in Adobe After Effects so that all layers in it also increase evenly and proportionally in time?

Answer 1

Select all layers in the timeline. Go to "layers" -> "time" -> "time stretch" and specify the coefficient we need as a percentage. Thanks to all

Answer 2

I don't know if there are other ways, but time stretching spreads the already set time keys throughout the timeline in the proportion that you increase the time.
I had to stretch the rest of the compositions (so that the elements simply did not disappear)
, so I had to manually set the time for all compositions in the project panel first, and then go into each one individually and pull out the timeline.
