Onion Skinning (Ghosting)

‘Onion skinning’ is an animation technique used to view previous and following keyframes at the same time. It is used to visualize the motion across multiple keyframes.

When working on a Flipbook in Sketchbook Pro, onion skinning is available via the Ghosting controls in the Flipbook timeline‍.

1. Toggle Ghosting of previous keyframes
2. Set number of previous keyframes to ghost
3. Set tint color for previous keyframes
4. Toggle Ghosting for next keyframes
5. Set number of next keyframes to ghost
6. Set tint color for next keyframes

Toggling Ghosting

By default, ghosting is off. To turn on ghosting, tap on  to view previous keyframes and/or  to view next keyframes. These are independent toggles and allow you to set ghosting controls separately for previous and next keyframes.

Number of ghosts

By default, two keyframes will be ghosted. You can define between 1-10 ghosts.

Color tint

By default, the ghost keyframes will appear semi-transparent.

• Tap-hold on the mini circular swatch to see the radial marking menu of preset colors. Gesture in the direction of color you want to select.

Applying different tints to previous and next ghosts can be extremely helpful to make them easily identifiable.
