Pixilation vs Rotoscope
ピクシレーション / ロトスコープ
Both sit in Animation Techniques, so the question is not what they belong to but how they behave. They are reached for with some of the same intent, which is where they get confused.
Pixilation
Pixilation treats live actors as stop-motion figures, photographing one held pose at a time. It turns walking into gliding and makes impossible movement or substitution while keeping real bodies and real places on screen.
Rotoscope
Tracing live-action footage frame by frame. Patented by the Fleischers, it mixes the gravity of live action with the freedom of drawing into a distinctive wavering line.
| Pixilation | Rotoscope | |
|---|---|---|
| Era | 1910s– | 1915– |
| Family | Animation Techniques | Animation Techniques |
| Kind | Technique | Technique |
| Cues | People gliding without stepping / Rigid body movement jumping between staged poses / People or objects appearing, disappearing or exchanging in one frame / Real streets and rooms where only gravity and time become discontinuous | Movement from live action / Wavering contours / Bodies with weight / Between film and drawing |
| Best used for | Creating flight, gliding or teleportation in a short or advertisement using performers and a real location · Turning bodily stiffness into comedy, unease or conflict rhythm in music and performance films | Showing the weight of human gesture or a crowd while staying in drawing · Converting live footage into drawing for reasons of texture or rights |
| Type | If type moves, let performers reposition it one frame at a time and match its travel interval to the interval between poses. | Redraw the lettering every frame so it wavers with the artwork |
| Composition | Lock the camera and mark each travel path on the floor. Set hold length and displacement before shooting and preserve background continuity. | Do not keep the live framing, redraw the background to clean it up |
| Material | Hold the actor for every exposure and record contact point, pose and clothing movement. Swap objects at identical position and light. | Vary the line weight and let the contour keep wavering |
| Caution | Low-frame-rate live action and frame dropping are not pixilation. The performer must take a discrete pose for each frame and physically reconstruct spatial relations. | Tracing without deciding what a drawing should keep and what it should drop, so the movement is accurate and the image has nothing to look at. |
