I'm gonna show two methods as they can both be useful, even though they both do the same thing in this case.
You are not winning time by choosing either one of these. Method 1 is versatile in the sense that you can choose exactly the layers you wish to speed up or speed down. With Method 2 you have to speed up or speed down the whole comp, but it leaves the old slower comp intact and each time you update the old comp, the new one is updated.
Method 1:
- Select all layers Ctrl+A.
- Alternatively you can select only those layers you wish to speed up or slow down.
- Top menu:
Layer > Time > Time Stretch...
.
- Enter new duration and press ok.
- Ctrl+K to change the comp duration to match.
On a Mac, use Cmd instead of Ctrl.
Method 2:
Make a new comp Ctrl+N.
- I'm going to call the old comp
Comp 1
.
- I'm going to call the new comp
Comp 2
.
Drag Comp 1
into Comp 2
.
- Make
Comp 2
the active comp.
- Top menu:
Layer > Time > Time Stretch...
.
- Enter new duration and press ok.
- Alternatively just resize the
Comp 2
footage in the timeline by grabbing the right side and dragging it.
- Ctrl+K to change the comp duration to match.
Since with this method you end up with more than one Comp, remember to select the comp(s) you wish to export, before adding it to media encoder queue.
On a Mac, use Cmd instead of Ctrl.
