11.7 Interpolation

Interpolation is the process of calculating the Frames in between the Keyframes.

Position the Timeline Cursor between Keyframes. Between Frame 1 and 15, between 15 and 17

(at frame 16), between 17 and 19 (at frame 18) and between 19 and 30. With the Cursor at each

intermediate position, with 2D Viewport Editor in Edit Mode, click on Interpolation in the 2D

Viewport Editor Header and select Sequence.

11.8 Onion Skinning

In previous examples you will have seen a ghost of the Stroke displayed showing the location

and shape of the Stroke at a previous Keyframe. This is a reference which allows you to modify

the Stroke at the current Keyframe. This technique is called Onion Skinning and may be

controlled in the Properties Editor Onion Skinning Tab.
