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.

Warning: Interpolation may not
work with complex Strokes
depending on the computer
power available to perform
calculations.
When Interpolation – Sequence is clicked frames are inserted in the Dope Sheet, Timeline
Editor.

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.
