How do I set keyframes on specific intervals in my animation?

When using interpolations, the timing of the animation is automatically spaced on ones, and the only way to change the timing is to set keyframes individually without interpolations. This technique can help you quickly convert your keyframe animation to twos, threes, or another type of timing a project might require. 

This article refers to keyframe timing. If you’d like to adjust drawing frame exposure, please see How can I change the exposure of all my drawings at once?

Step 1: Use the Create Keyframes On button

1. In the Timeline view, select the keyframes range you wanted to set keyframes on.

2. If you don’t see the Timeline View toolbar, in the top menu, select Windows > Toolbars > Timeline View.
3. In the Timeline View toolbar, select the Create Keyframes On button.

4. The Create Keyframes On dialog box appears:

5. The following options can be edited:
   • Every Number of Frames: A number that determines the spacing of the keyframes. 2 will put your animation on twos, 3 on threes, and so on.
   • Keep Existing Keyframes: If checked, any pre-existing keyframes will remain regardless of the chosen timing. Leave unchecked if you want consistent timing.
   • Force Keyframes at End: If checked, a keyframe will be made on the last selected frame regardless of the chosen timing.
   • Selection: Allows you to adjust the selected range of keyframes by inputting frame numbers.
6. Once done, select the OK button.
7. Keyframes in the selected range will now be spaced according to the value that was put into the Every Number of Frames field. Interpolations will also be removed.
