Animated pre-visualization of complex scenes with rough animation, edit, sound — establishes camera moves, timing, cutting rhythm before shooting. Saves set time and budget.
Before the first camera rolls, a cinematic skeleton is created on the computer — raw material that anticipates timing, editing, and camera movement in broad strokes. This animatic is called previs, and it has long been standard not just for blockbusters. On location, it shows you how a complex sequence should breathe, where the cuts should be, how long a move will take. This saves decision-making vacuums and waste on set.
The material typically arises from storyboards, which an animator translates into simple 3D geometry or 2D animations. Camera moves are simulated, edit transitions are placed, and a temporary soundtrack — or just a click track for timing — is laid underneath. The resolution is deliberately low, the quality secondary. It's about rhythm and spatial logic. A chase scene through a factory? You see in advance where the transitions between interior and exterior shots occur, how long each shot lasts, whether a move takes three or ten seconds. The whole thing is iterative — the director watches, changes, re-animates until the timing is right.
On set itself, the previs becomes a physical reference. The cinematographer films according to it, but not slavishly — reality has its peculiarities, actors perform differently than in animation. Previs is a compass, not a chain letter. However, it saves massive amounts of time on technically demanding scenes: VFX sequences where cameras must be precisely placed, or chase scenes that leave no room for improvisation. The editor will later work with completely different footage, but the tempo that the director defined in previs remains the inner pulse of the scene.
Important: Previs is not a storyboard replacement, but its logical continuation into time. It doesn't answer the question "What do I see?", but "How quickly do I see it, and in what sequence?". For action scenes or complex VFX mapping, it is indispensable. For character dramaturgy, it can seem exaggerated — here it suffocates rather than helps. The best previs is the invisible kind: the director has found their timing, the set runs like clockwork, and no one notices that hours of pre-production on the computer were needed.
