Add or Remove Time Between Keyframes

FIRST THINGS FIRST:

• Even though the right-click command says “Add/Remove Time from Keyframe,” it’s a lie. You’re adding or removing time after the keyframe.

• Compounding the problem is that the dialogue box instructions say, “To add time to the end of a slide, select the last keyframe. To remove time, enter a negative number,” This is misleading because, if the last keyframe is all the way to the right, you can’t subtract time. Not ever.

FOUR TIPS:

• Making changes to a keyframe at the beginning of or within a transition area changes the transition time, not the base slide time. Unless this is what you really want to do, zero out the transition before adding/removing time. It will make life easier.

• Time is added or removed a tiny fraction to the right of the keyframe. The same amount of time will be added/removed in precisely the same location in any other layers.

• Open the keyframe editor before you make any changes so you can see where the time change will occur in other layers.

• Don’t work on the original slide. It’s too easy to mess things up. Instead, copy the slide and make changes to the copy. If it works like a charm, delete the original and use the copy; if it doesn’t work, you still have the original.

CONCLUSION:

Play with the command. Getting comfortable with it is truly worth your time for even the simplest situation. If, say, you have just one layer with 4 keyframes, you can quickly change the timing between keyframes 2 and 3 without affecting the time before or after them.
