Buyer guide

Storyboard generator vs previs softwareWhich pre-production tool fits the job.

Storyboard generators, 3D previs software, and game-engine previs solve different pre-production problems. Compare M Studio, Boords, Katalist, FrameForge, Previs Pro, Cine Tracer, ShotPro, and Unreal by fidelity, speed, cost, and who can use them.

Section 01

Quick answer

An AI storyboard tool answers what each shot looks like; previs software answers whether the camera, lens, and blocking work in the real space. For early pre-production, pitches, and most short films and commercials, an AI storyboard tool such as M Studio is enough, and it produces a timed animatic in one session from $27/month. For VFX-heavy sequences, stunts, and technical camera planning, use 3D previs software such as FrameForge or Previs Pro, or Unreal Engine with a previs artist. Many productions use both.

Section 02

Definitions: storyboard generator, previs software, pre-production tools

The three terms overlap in search results but describe different tools. Set the definitions first so the comparison is fair.

AI storyboard tool

Software that creates storyboard frames from a script or prompt with an image model, then arranges them in shot order. Output: 2D frames, a PDF, and often a timed animatic. Examples: M Studio, Katalist, LTX Studio.

Previs software

Software that builds a scene in 3D with real camera and lens models so a director and DP can test blocking, camera moves, and timing before the shoot. Output: 3D animation, camera data, and shot diagrams. Examples: FrameForge, Previs Pro, Cine Tracer, Unreal Engine.

Pre-production tools

The wider stack: script software, breakdown and scheduling, shot lists, storyboards, previs, casting, location, and budget. Storyboards and previs are the two visual planning tools in that stack.

Animatic

A storyboard timed to audio. It sits between a board and previs: it tests pacing but not camera physics. AI storyboard tools usually include one; 3D previs software produces motion instead.

Section 03

AI storyboard generator vs previs software — side by side

Fidelity = how close the output is to what the camera will capture. Speed = time from script to first reviewable sequence. Prices are list prices at time of writing; competitor prices change, so confirm on the vendor page.

The two tools fail in opposite directions. An AI storyboard tool cannot tell you that a 24mm lens will not fit the room, and a 3D previs tool cannot show a client the mood of a scene in ten minutes. Choose by the question you need answered this week. Most productions answer the storyboard question first because it is cheaper and reaches more people.

Cost is not the deciding factor. Previs Pro and Cine Tracer cost less than $120 a year or one-time; the expense of 3D previs is the specialist time to build sets and block the scene. An AI storyboard tool shifts that time to review: you spend minutes on generation and hours on shot choice.

Section 04

Which pre-production tool to use, by situation

Pitch, treatment, or client approval

AI storyboard tool. You need mood, framing, and sequence for people who do not read 3D scenes. M Studio, Katalist, and LTX Studio all fit; M Studio adds a timed animatic with voice.

Short film or commercial with simple coverage

AI storyboard tool plus a shot list. Previs is rarely worth the setup time unless there is a stunt or a complex camera move.

Location shoot with tight blocking

3D previs software. FrameForge and Previs Pro model the real space and lens so the DP can commit to camera positions before the crew arrives.

VFX sequence or virtual production

Game-engine previs. Unreal Engine gives frame-accurate camera and lighting data that the VFX team reuses. A storyboard still comes first to agree on the shots.

Animation and drawn boards

Toon Boom Storyboard Pro or Boords for artist-drawn boards with animatics; these are storyboard tools, not previs, but they are the industry standard for animation planning.

Section 05

Where M Studio fits between storyboards and previs

M Studio is an AI storyboard tool that reaches into previs territory without 3D. It parses the script, generates a consistent frame per shot with character references, times the board into an animatic with voice, music, and sound, and can turn each frame into a video clip with MiniMax H3, WAN 3.0, HappyHorse (Wan), or Gemini Omni. That gives a director motion, pacing, and mood for review in the same afternoon.

It does not replace technical previs. There is no lens model, no set measurement, and no camera data export. Use M Studio to decide what the film looks like and how it plays, then hand the locked shots to FrameForge, Previs Pro, or an Unreal previs artist for the sequences that need physical accuracy. Plans start at $27/month; there is no free plan.

Section 06

How to choose between a storyboard generator and previs software

Name the question

"What does it look like?" is a storyboard question. "Will the camera fit?" is a previs question. Buy the tool that answers your question.

Count who must review it

If producers and clients review, the output must be a PDF or a video they can open. If only the DP reviews, 3D scene files are fine.

Plan the handoff

Storyboard first, previs second, on the shots that need it. Make sure the storyboard tool exports shot numbers and frames the previs artist can reference.

How it works

From script to screen in six steps

M Studio builds a film shot by shot, and you direct every shot — this is the whole path, start to finish.

  1. 01

    Start a film

    Start from a one-line brief, or import a screenplay PDF and build straight from the pages you already wrote.

  2. 02

    Add your script

    Scenes, action and dialogue laid out shot by shot — editable line by line before anything renders.

  3. 03

    Add your characters

    Add each character once with a reference image so the same face carries across every shot in the film.

  4. 04

    Build the storyboard

    Your script breaks into shots on a canvas. Reorder, reframe and re-prompt any shot until the board reads right.

  5. 05

    Make the video clips

    Turn approved storyboard pictures into video clips one shot at a time, then layer voiceover, music and sound effects.

  6. 06

    Export the cut

    Take the finished cut out as an MP4, MOV or WebM, up to 4K, ready for the edit or the pitch.

There is no length cap in the editor. Because films are made shot by shot, how long a film can run comes down to how many video clips your plan includes — not a limit in the tool.

FAQ

Frequently asked questions

Previs software builds a scene in 3D with real camera and lens models so a director and cinematographer can test blocking, camera moves, and timing before the shoot. Examples are FrameForge, Previs Pro, Cine Tracer, ShotPro, and Unreal Engine used for virtual production.

A storyboard is a sequence of 2D frames that shows what each shot looks like and in what order. Previs is a 3D or animated version that tests camera, lens, blocking, and timing in a modelled space. An animatic, a storyboard timed to audio, sits between the two.

No. An AI storyboard tool such as M Studio produces frames and animatics, and can generate video clips, but it has no lens model or set measurement. It covers early pre-production and pitching; 3D previs software covers technical camera planning.

A typical stack is screenplay software, a breakdown and scheduling tool, a shot list, a storyboard tool, previs software for complex sequences, and casting, location, and budget tools. Storyboards and previs are the two visual planning steps.

Usually not. A storyboard and a shot list cover most short films and commercials. Add 3D previs only for a stunt, a complex camera move, a tight location, or a VFX shot where camera data must be exact.
