Imagine being able to “watch” your film before shooting a single scene. That’s the magic of Pre-Visualization, or previs.
Previs is one of the most crucial stages in VFX-heavy productions, allowing directors, cinematographers, and animators to plan complex shots with precision.
What is Previs?
Pre-Visualization is the process of creating simplified versions of scenes—often using rough 3D animation—to preview sequences before they’re fully produced.
Think of it as a dynamic storyboard with basic motion, camera angles, and timing.
Why Previs is Critical
- Saves Time and Money: Mistakes caught in previs prevent costly reshoots.
- Visual Planning: Helps plan camera moves, effects timing, and actor positioning.
- Team Alignment: Everyone—VFX artists, DOPs, editors—gets on the same page.
Risk Management: Identifies technical challenges early (e.g., VFX feasibility).

Previs in Action
In films like Avengers: Endgame or Avatar, previs was used to map out battles, action sequences, and camera paths—ensuring tight coordination across massive teams.
Key Components of a Previs Sequence
- Simplified 3D models and environments
- Placeholder animation and characters
- Rough camera movements
- Basic lighting and visual effects
- Timing synced with temporary sound or dialogue
Tools Used in Previs
- Autodesk Maya – standard 3D animation platform
- Blender – free and flexible
- ShotGrid – for production tracking and review
- Unreal Engine – rising in real-time previs
Related Disciplines
- Techvis – focuses on technical planning like crane lengths or lens options
- Postvis – adds rough VFX after live-action shooting to aid editing
Final Thoughts
Previs is where imagination meets planning. It lets you rehearse, rethink, and refine your vision—before the cameras roll.
If you’re aiming for a role in directing, cinematography, or production coordination, learning previs will set you apart.
