What is pre-visualization?
Before a single frame of a major film is shot, the key sequences already exist as video. They look rough, but they tell the director, producer, and department heads exactly what will be needed on set. This process is pre-visualization, and it has traditionally been one of the most expensive parts of pre-production.
Definition
Pre-visualization (pre-viz) is the creation of rough video representations of planned scenes, shots, or sequences before full production begins.
Pre-viz serves as a communication tool: it helps directors convey their visual intent, allows producers to assess production requirements, and enables department heads to plan resources before committing to expensive live production.
Pre-viz ranges from simple animatics (moving storyboard frames with basic timing) to more detailed 3D pre-viz with rough character proxies, camera moves, and lighting, all the way to "techvis" (technical visualization) that specifies exact camera positions, lens choices, and lighting setups for VFX-heavy sequences.
Why pre-viz matters
Production decisions made during pre-viz are cheap. The same decisions made on set, with a full crew and actors waiting, cost orders of magnitude more.
A director who can show a pre-viz of a complex action sequence can get stakeholder buy-in, identify practical production problems early, and walk their cinematographer through exactly the coverage they need. Without pre-viz, these conversations happen on set or in post, where changes are expensive.
For VFX-heavy productions, pre-viz is where the production team and VFX supervisors align on what will be shot practically versus generated digitally. This alignment determines budgets, shooting schedules, and on-set requirements.
Traditional pre-viz workflow
Traditional pre-viz uses 3D animation software (Maya, Cinema 4D, MotionBuilder) with rough placeholder assets: low-polygon characters, basic environments, simple cameras. A pre-viz team animates these to match the director's intended coverage.
The result is functional but time-consuming. A single pre-viz sequence can take days to produce, requiring specialist 3D artists who understand both the technical software and the language of cinematography.
AI-generated pre-viz
Generative video changes the economics of pre-viz substantially. A director or producer who can describe a shot in text or sketch a reference image can generate rough motion footage in seconds rather than days.
This does not replace traditional pre-viz for complex VFX-heavy productions where exact camera and lighting specifications are needed. But for early-stage creative development, pitch presentations, and stakeholder alignment, AI-generated pre-viz compresses timelines that previously took weeks into hours.
The primary use cases: generating visual options for different shot approaches before committing to a specific camera setup; quickly producing animatic-level timing references for editorial; and creating pitch materials that communicate visual ambition without a full pre-viz investment.
Studios using LTX-2 for pre-viz have reported up to 85% faster turnaround compared to traditional pre-viz pipelines, with significant reductions in production costs on complex sequences.
How LTX-2 supports pre-viz workflows
LTX-2's camera control conditioning allows directors to specify camera behavior (dolly, pan, tilt, orbit, zoom) as part of the generation input, producing pre-viz footage with intentional camera movement rather than the static or drifting camera that unconditioned models produce.
The camera control guide covers how to specify shot types and camera moves for pre-viz use cases. For studios evaluating LTX-2 for production pre-viz workflows, the video generation model overview covers technical capabilities and enterprise deployment options.
