Presentation Animation

Apply Disney's 12 animation principles to Keynote, PowerPoint, Google Slides, and presentation software.

Quick Reference

Principle	Presentation Implementation
Squash & Stretch	Bounce emphasis, elastic scaling
Anticipation	Build sequences, pre-reveal fades
Staging	Focal point management, dimming
Straight Ahead / Pose to Pose	Morph vs discrete transitions
Follow Through / Overlapping	Staggered builds, delayed elements
Slow In / Slow Out	Ease animations, avoid linear
Arc	Motion paths, curved entrances
Secondary Action	Supporting graphics follow primary
Timing	Builds 0.3-0.5s, transitions 0.5-0.8s
Exaggeration	Emphasis effects, attention draws
Solid Drawing	Consistent alignment, visual balance
Appeal	Professional polish, purposeful motion

Principle Applications

Squash & Stretch: Use bounce effect sparingly for playful emphasis. Scale animations should feel elastic not mechanical. Key numbers can "pop" with slight overshoot.

Anticipation: Fade out previous content before new appears. Slight pause after slide transition before builds begin. Dim existing elements before highlighting new ones.

Staging: One focal point per moment. Dim completed content to 30-50% opacity. Use motion to direct eye path. Build complex diagrams piece by piece.

Straight Ahead vs Pose to Pose: Morph transitions (Keynote Magic Move, PowerPoint Morph) create fluid straight-ahead motion. Standard builds are pose to pose. Use morph for transformation stories.

Follow Through & Overlapping: Build related items with 0.1-0.2s delays. Supporting text follows primary graphic. Bullet points stagger naturally. Don't animate everything simultaneously.

Slow In / Slow Out: Always use ease-in-out or ease-out. Never linear—looks robotic. Keynote: "Ease In & Out". PowerPoint: use custom motion paths with curve handles.

Arc: Motion paths should curve naturally. Elements entering from sides arc inward. Exit animations arc toward edges. Straight lines feel mechanical.

Secondary Action: Icons animate alongside text reveals. Arrows appear as relationships are explained. Background subtle shifts support primary content.

Timing: Text builds: 0.3-0.5s. Graphic reveals: 0.4-0.6s. Slide transitions: 0.5-0.8s. Complex sequences: 0.2-0.3s between elements. Match pacing to speaking rhythm.

Exaggeration: Use scale emphasis for key points. Pulse effect for critical numbers. Shake for contrast/disagreement. Reserve exaggeration for truly important moments.

Solid Drawing: Maintain grid alignment during motion. Consistent transform origins. Elements should feel anchored to the slide structure.

Appeal: Purposeful animation builds credibility. Excessive motion distracts and annoys. Every animation should serve communication.

Software Patterns

Keynote

Best builds: Dissolve, Move In, Scale
Magic Move: Most powerful transition—objects morph between slides
Timing: Use "Build Order" panel for precise sequencing
Tip: Group objects that should animate together

PowerPoint

Best entrances: Fade, Fly In (with custom path)
Morph transition: Objects with same name transform
Timing: Animation Pane for sequencing
Tip: Use "With Previous" + delay for stagger

Google Slides

Limited but functional: Fade, Fly in
No morphing: Use Fade for cleanest transitions
Timing: Less control—keep animations simple
Tip: Fewer, better animations beat many poor ones

Build Sequences

Content Type	Animation	Duration	Delay
Title	Fade + Scale	0.5s	0s
Subtitle	Fade	0.4s	0.2s
Bullet 1	Fade + Move	0.3s	0.3s
Bullet 2+	Fade + Move	0.3s	+0.15s each
Image	Scale from center	0.5s	varies
Chart	Custom/Wipe	0.6s	varies

Presenter Tips

Animate on click, not automatically—control your pacing
Practice with animations—know what comes next
Less is more—animation should clarify, not decorate
Test on presentation display—timing feels different at scale
Have a backup with no animations for technical issues
