Key Takeaways
- Previsualization lets filmmakers test camera positions, blocking and timing before the shoot, catching expensive problems while they’re still cheap to fix.
- Common methods include storyboards, shot lists, animatics, video previs, 3D previs and floor plans, choosing whichever answers the scene’s specific questions.
- A simple 7-step workflow (purpose, beats, location, rough visual, timing, crew review, updated documents) works without expensive software or a dedicated previs team.
Introduction
A complicated shot can look effortless on screen. Behind the scenes, though, it may involve actors, cameras, lighting, stunts, visual effects and crew members all moving at exactly the right moment. That’s a lot to leave until the day of the shoot!
Previsualization, usually shortened to previs, lets filmmakers test those moving parts before production begins. By creating a rough visual version of a scene, the team can explore camera positions, blocking, timing and technical requirements while changes are still relatively quick and inexpensive.
Previs doesn’t need to look polished, and it certainly isn’t there to create a miniature version of the finished film. It’s to help everyone understand the plan, identify potential problems and avoid costly surprises on set.
And in today’s blog, we’ll be investigating exactly what previs is and how it can help with your next production!
Let’s begin!
What Is Previsualization?
Previsualization is the process of creating an early visual representation of a scene before it’s filmed.
This might take the form of:
- Storyboards
- Shot lists
- Animatics
- Floor plans
- Phone-recorded rehearsals
- Three-dimensional environments
- Virtual camera tests
A large production might create a detailed digital version of an action sequence. An independent filmmaker might ask friends to act out the scene while recording it on a phone. Both approaches count as previs if they help answer practical or creative questions.
Previs can show where actors and cameras will move, how shots will connect, which moments need coverage and whether the audience will understand the action. The screenplay explains what happens and previs begins deciding how the audience will see it.
Why Productions Use Previs
The main advantage of previs is simple: it’s cheaper to discover a problem before the shoot than during it.
Imagine arriving at a location and realising there isn’t enough room for the camera move you’ve planned. Perhaps a stunt can’t be performed safely from the intended angle, or a scene requires twice as many setups as the schedule allows.
Previs gives you an opportunity to solve those problems before a full cast and crew are waiting.
1. It Creates a Shared Visual Plan
A screenplay can create different images in different people’s minds.
The director may imagine a handheld sequence, while the cinematographer pictures controlled tracking shots. The production designer may build around an area the director doesn’t intend to show.
Previs gives everyone something specific to discuss. Instead of vaguely describing a shot, the team can look at the proposed movement, identify practical issues and agree on the intended effect.
2. It Reveals Technical Challenges
Complex scenes often depend on several departments working together. A stunt may need to land within a particular part of the frame. An actor may need a clear eyeline for a digital creature. A practical effect could require the camera and crew to remain outside a safety zone.
Previs won’t solve every problem, but it’ll reveal which questions need answering before filming.
3. It Saves Time and Money
Production days are expensive. Delays can affect location access, equipment hire, overtime and actor availability. Testing the scene in advance can help you estimate how many setups are required and which shots are genuinely necessary.
You may discover that one moving shot can replace several separate setups. You might also realise that an ambitious idea adds little to the story and isn’t worth the time it’ll take.
4. It Supports Safer Filming
Previs is particularly useful for scenes involving stunts, vehicles, crowds, animals or special effects. Planning the action visually helps the team understand movement, distance and timing before anyone attempts the full sequence.
It should never replace professional safety planning, but it can support the process by making the intended action clearer.
5. It Strengthens the Edit
An impressive shot may still fail to connect clearly with the shots around it.
Previs lets filmmakers assemble a rough version of the scene and test its rhythm. Is an important reaction missing? Does the audience understand where everyone is? Does the sequence build tension or become repetitive?
It’s much easier to add a rough close-up during pre-production than to discover in the edit that you never filmed one.

Common Previs Methods
There isn’t one correct way to previsualize a film. The best method depends on the scene and the problem you’re trying to solve.
Storyboards
Storyboards use drawings or images to represent the main shots. They can communicate composition, camera angles, movement and character positions. They’re especially useful for action, visual effects, comedy and scenes where framing matters.
The artwork doesn’t need to be beautiful. Stick figures are perfectly acceptable if everyone understands the shot.
Shot Lists
A shot list records the coverage needed for a scene, including shot size, subject, camera movement and technical requirements.
Storyboards show what shots could look like. The shot list turns them into a practical production plan.
Keeping the screenplay, storyboards and shot list together in a pre-production workspace such as Celtx can reduce the risk of crew members working from different versions.
Animatics
An animatic turns storyboard panels into a timed video, often with temporary dialogue, sound or music. It gives filmmakers a clearer sense of pacing than static images can. Animatics are particularly useful for action sequences, animation, title sequences and scenes that need to match music.
Video Previs
Video previs involves recording a rough version of the scene with stand-ins, simple props or available locations.
You can test blocking, camera positions and edits with little more than a phone. It’s a practical option for independent productions because it shows how people and cameras will move through the space.
Three-Dimensional Previs
Three-dimensional previs uses digital models of locations, characters and cameras.
It can help filmmakers test lenses, camera moves and effects-heavy sequences before entering the real location or studio.
The model only needs enough detail to answer the production’s questions. Spending too long perfecting it defeats the purpose.
Floor Plans
Sometimes an overhead diagram’s more useful than a polished storyboard. A floor plan can show entrances, furniture, actor positions, camera placement and movement paths. It’s especially helpful for scenes involving several characters or complicated blocking.
Building a Simple Previs Workflow
You don’t need expensive software or a dedicated previs team. Start with the scenes carrying the greatest creative, financial or technical risk.
Step 1 | Identify the Scene’s Purpose
Before choosing shots, ask what the scene needs to achieve. What changes? Whose perspective matters? What information does the audience need? Where should their attention be at the end?
In the end, your visual choices should serve the story rather than exist simply because they look impressive.
Step 2 | Mark the Essential Beats
Break the scene into its main actions and emotional turns.
For example:
- A character enters unnoticed
- They overhear a secret
- Someone sees them
- The room falls silent
- They decide whether to run
These beats will help you decide which moments need their own shots.
Step 3 | Sketch the Location
Create a basic floor plan showing doors, windows, furniture and obstacles. Add the approximate positions of actors and cameras. This can quickly reveal whether a planned move is physically possible.
When you’re using a real location, take photographs and measurements during the scout.
Step 4 | Create a Rough Visual Version
Choose the quickest method that answers your questions. Sketch frames, use reference images, record the blocking on a phone or build a simple digital environment. But don’t waste time polishing details the crew doesn’t need.
Step 5 | Test the Timing
Edit your images or test footage together. Add temporary dialogue, music or effects when they influence timing. You may discover that a movement takes too long, an action happens too quickly or an important reaction’s missing.
Step 6 | Review It with the Crew
Share the previs with the cinematographer, assistant director, production designer, stunt coordinator and any other department affected by the scene. Ask:
- Can we achieve this in the available space?
- How long will each setup take?
- Does it require specialist equipment?
- Are there any safety concerns?
- Can anything be simplified?
Step 7 | Update the Production Documents
Once the approach has been agreed, update the shot list, storyboards, breakdown and schedule. Keep the approved information in one central workspace so everyone knows which version’s current.

Common Previsualization Mistakes
These mistakes show up again and again once teams start previsualizing scenes, and each one is easy to avoid once you know to look for it.
Planning Every Scene in Too Much Detail
Not every conversation needs a detailed animation. Save extensive previs for scenes involving complicated movement, effects, limited time, safety concerns or expensive production elements.
Treating Previs as the Finished Film
Previs is a guide and definitely not a contract. A location may suggest a better composition. An actor may find a more truthful movement. Unexpected light may create an opportunity nobody planned. Preparation should support discovery, not prevent it.
Prioritizing Spectacle Over Story
It’s easy to become attached to a complicated camera move. Ask whether it reveals character, communicates information or strengthens emotion. If it doesn’t, it may only consume time you need elsewhere.
Making the Previs Too Polished
A previs sequence doesn’t need perfect animation or finished visual effects unless those details are necessary to make a decision. The more finished it looks, the harder it may be for collaborators to suggest changes.
Leaving Out Key Departments
A shot that works creatively may create problems for lighting, sound, design, safety or scheduling. Involve department heads early enough for their expertise to influence the plan.
Failing to Update It
Previs becomes confusing when it no longer matches the screenplay, location or schedule. Use clear version names and update the relevant production documents whenever the plan changes.
FAQ
Storyboarding is one form of previs. Previsualization can also include animatics, video tests, floor plans, shot lists and digital environments.
Every film benefits from visual planning, but not every scene needs detailed previs. Focus on sequences where mistakes would be expensive, dangerous or difficult to fix.
Absolutely. A phone camera, basic editing software and a few stand-ins can reveal valuable information. Effective previs depends more on asking useful questions than having expensive technology.
It should be detailed enough to solve the problem. A rough animatic may be enough to test pacing, while a stunt or visual effects sequence may require more precise information.
Start during pre-production, once the script’s stable enough to plan but early enough for your discoveries to influence the budget, schedule, locations and design.
No. The term started in still photography, where Ansel Adams used it to describe visualizing the finished print before pressing the shutter. It’s also used in animation and visual effects to plan shots digitally before any rendering begins. This post focuses on how previs applies to live-action film production.
Conclusion
Previsualization gives filmmakers a safe and flexible space to make mistakes before those mistakes become expensive.
It can reveal that a camera move won’t fit, a sequence needs another shot, or an ambitious idea can be achieved more simply. It also gives different departments a shared visual language before they arrive on set.
The aim isn’t to remove spontaneity from filmmaking. It’s to arrive prepared, knowing which decisions have already been tested and where there’s still room to experiment.
Plan the difficult parts, communicate your intentions and keep the approved information organized. You’ll spend less time solving preventable problems and more time capturing the moments that make the film worth watching.
