Portable Pivot Stickfigure Animator: Quick Guide to Creating Smooth Animations
What it is
Portable Pivot Stickfigure Animator is a lightweight, standalone version of the classic Pivot stickfigure animation tool. It focuses on frame-by-frame stick-figure animation with a simple, drag-and-drop interface and supports onion-skinning, adjustable frame rates, and export to GIF/PNG sequences.
Quick setup
- Download & run: Extract the portable package and run the executable—no installation required.
- Create a new animation: File → New; set canvas size and frame rate (24 fps for smooth motion).
- Add figures: Insert stick figures from the library or draw custom ones using nodes and limbs.
- Save often: Use Save or Save As to store .piv files (project files) and export copies.
Core workflow for smooth animations
- Plan the motion: Sketch a simple storyboard or key poses for major beats (start, mid-action, end).
- Set keyframes first: Place the main poses on separate frames—these define motion extremes.
- Use onion-skinning: Enable onion-skins to view surrounding frames and maintain fluid continuity.
- Interpolate with in-betweens: Add intermediary frames between keyframes to smooth transitions; aim for consistent spacing.
- Adjust timing: Vary the number of frames per pose for weight and emphasis (fewer frames = snappier; more = slower).
- Refine arcs and easing: Move joints along curved paths where appropriate; apply ease-in/out by spacing frames nonlinearly.
- Preview frequently: Play the animation at target fps and tweak problematic frames.
Useful settings & tips
- Frame rate: 12–24 fps for simple stick animations; 24 fps looks smoother.
- Onion-skin opacity: Lower opacity to avoid visual clutter but keep enough to align limbs.
- Lock layers: If supported, lock background elements to prevent accidental edits.
- Export options: Export as GIF for quick sharing or PNG sequence for editing in other software.
- Keyboard shortcuts: Learn frame-next, frame-prev, copy/paste frame shortcuts to speed workflow.
Common pitfalls and fixes
- Choppy motion: Add more in-betweens or increase fps.
- Popping limbs: Smooth the path of joints and adjust spacing between frames.
- Off-model drift: Use reference frames or duplicate the base figure to keep proportions consistent.
Quick example sequence (5 frames at 24 fps)
- Frame 1 — starting pose.
- Frame 3 — anticipation (crouch).
- Frame 5 — action peak (jump/strike).
- Frame 8 — follow-through begins.
- Frame 12 — landing/settle.
Export checklist
- Set final FPS.
- Trim empty frames.
- Export GIF or PNG sequence.
- Test playback in target player.
