Best AI tools for consistent characters 2026The same face in every shot.
How Runway, Kling, Luma, LTX Studio, Katalist, Higgsfield, Google Flow, Midjourney, and M Studio keep one character's face and look across many shots: what you give each tool, how many references a shot takes, and whether the character follows the shot into video.
Last updated · M Studio Editorial
We make M Studio. We compared every tool on the same criteria, using each vendor's own site and pricing page.
Which AI tool keeps the same character in every shot?
Every tool here keeps a character the same way: it sends a picture of the character to the model with each shot, not only a description. The tools differ in three ways. How you set the character up (one image, a set of 2 to 4 images, or a trained identity). How many references one shot takes. And whether the character holds across a whole film or only inside one generation.
For a single striking shot or a short sequence, Kling Elements, Runway References, Luma Ray3, and Higgsfield are strong. For one face across many separate images, Higgsfield Soul ID trains an identity on 20 to 80 photos. For a cast across a whole storyboard that becomes a film, M Studio (we make it), Katalist, and LTX Studio keep the characters in the project, so you do not re-upload them shot by shot. No vendor promises the same face in 100% of shots.
Section 02
Quick picks by job
A cast across a whole film or storyboard
M Studio: each character has a reference image, and @char in a shot's prompt sends it to the model for the still and for the video clip. Katalist and LTX Studio also keep characters in the project.
Many characters in one video shot
Kling: Video 3.0 Omni takes up to 7 elements in one generation (4 when a video is in the input), and Kling image generation takes up to 10.
One person's face across hundreds of images
Higgsfield Soul ID: train it once on 20 or more photos of one person (up to 80), and the Soul models apply that face to each generation.
Putting a real performance on a new character
Luma Ray3: character reference applies one reference image to a performance in video-to-video and holds likeness and costume across the modified clip.
Free to try with consistent characters
Google Flow: Ingredients to Video keeps a character from clip to clip, and Flow gives 50 free credits a day without a Google AI plan.
Section 03
Comparison: how 9 tools keep a character consistent
References per generation = how many images (characters, props, places) one generation can take. Carries into video = the same reference works for video clips, not only for stills. All facts come from each vendor's own pages, checked on 27 October 2026.
Two limits matter most. The first is references per generation. A shot with three named people and a set needs four references, so a 1-reference tool forces you to compose the shot in steps. The second is whether the reference follows the shot into video. A character can hold in the still and change face in the clip, and you only see it if you test video.
AI tools for consistent characters across shots, compared in October 2026
Tool
How you set the character
References per generation
Carries into video
Kept across a project
M Studio
A reference image per character (an uploaded photo or a generated design sheet), named in a shot's prompt as @char
Up to 4 named people a shot (fewer if the image model takes fewer); a shot whose character has no reference image is stopped, not drawn without it
Yes: the reference also goes to the MiniMax H3 clip
Yes: the cast, locations (@location) and the film's look (@look)
Runway (Gen-4 References)
Tag a reference image and call it with @ in the prompt
Up to 3
References are a Gen-4 Image feature
Tagged references are saved and can be shared with a workspace
Kling (Elements)
An element of 2 to 4 images of one character, or an element made from a video; a voice can be bound to it
Up to 7 in video (4 with a video input); up to 10 in images
Yes
Yes: an Element Library (up to 30 elements without a membership, up to 500 on Ultra)
Luma (Ray3)
One character reference image
1
Yes, across a modified clip (video-to-video)
Not listed
LTX Studio (Elements)
Saved Elements: characters, objects and locations
Not listed
Yes, in the same project
Yes; saving Elements is on the $35/month Standard plan
Katalist
Cast a character once from a reference
Not listed
Yes, storyboard and video
Yes; 1 custom character on Essential, 10 on Pro, unlimited on Unlimited
Higgsfield (Popcorn, Soul ID)
Popcorn takes image references; Soul ID trains on 20 to 80 photos of one person
Up to 4 (Popcorn)
Popcorn makes still sequences of up to 8 frames; Soul ID works in the Soul image models
Soul ID: yes, a trained identity you reuse
Google Flow (Ingredients)
Add ingredient images, or call an uploaded asset with @ in the prompt
Not listed
Yes: Ingredients to Video; a voice reference can be added
Assets stay in the Flow project
Midjourney (Edit model)
Attach reference images; V8 replaces Character Reference and Omni Reference with the Edit model
Runway, Luma, Midjourney, Google Flow, and Higgsfield Popcorn. You attach the picture to each generation. It is quick and needs one good photo. Higgsfield's own help page says a single reference anchors one generation but can drift across many separate ones.
A saved character in a library or project
Kling Elements, LTX Studio Elements, Katalist, and M Studio. You set the character up once and call it by name in each shot. Kling and M Studio use @ mentions in the prompt.
A trained identity
Higgsfield Soul ID. Training on 20 to 80 photos of one person takes a few minutes, and the Soul models then hold that face across styles and angles. It works for one real person, and only in the Soul models.
Section 05
How M Studio keeps a cast consistent
Each character in an M Studio film has a reference image: a photo you upload or a design sheet M Studio draws. When you paste a screenplay, M Studio reads the cast and writes each shot's prompt with the characters named as @char mentions. At Generate, each mention attaches that character's newest reference image, in the order the prompt names them. On a video model that reads reference audio, the character's saved voice sample can go too.
Sets work the same way with @location, and @look sends the film's look picture for colour and light. Nothing that is not mentioned is attached. If a mention cannot be honoured, for example a character with no reference image, the shot is not generated, so a face is never dropped without a word. Every video model M Studio offers accepts reference images, so the reference follows the still into the clip.
Where M Studio is weaker: there is no trained identity like Soul ID, so the likeness depends on how well the chosen model reads the reference. A shot holds at most 4 named people, fewer if the image model takes fewer references. Clothes are written in each shot's prompt, not locked by the reference, so you check wardrobe shot by shot. There is no free plan.
Section 06
How to test character consistency before you pay
Use a hard scene
Two people, a profile shot, a wide shot, and a close-up. One front-facing portrait proves very little.
Count references per shot
Add up the people, props, and sets your busiest shot needs, and check the tool's limit per generation.
Take it into video
Animate three of the stills. A face that holds in the still and changes in the clip is the drift that costs the most to fix.
Change the costume on purpose
Ask for a new outfit in scene 2. A good tool keeps the face and changes the clothes; a weak one changes both or neither.
Section 07
How we evaluated these tools
M Studio publishes this guide, and M Studio is one of the tools in it. Read the ranking with that bias in mind. We compared each tool on how a character is set up, references per generation, whether the reference carries into video, and whether the cast is kept across a project. Competitor features and starting prices come from each vendor's own website and pricing page, checked on 27 October 2026. Where a vendor does not publish a fact or a price, the table says "not listed".
A star rating is our editorial judgement of fit for the job this guide covers (5 = strongest). We do not give M Studio a rating. It is not a user review score or a lab benchmark, and we did not run paid side-by-side tests of every tool.
Where other tools are stronger than M Studio: Higgsfield Soul ID trains an identity on 20 to 80 photos, which M Studio does not do. Kling takes up to 7 elements in one video and binds a voice to a character. Luma Ray3 puts a character on a real actor's performance. Google Flow lets you try Ingredients to Video free with 50 credits a day. M Studio has no free plan.
M Studio builds a film shot by shot, and you direct every shot — this is the whole path, start to finish.
01
Start a film
Start from a one-line brief, or import a screenplay PDF and build straight from the pages you already wrote.
02
Add your script
Scenes, action and dialogue laid out shot by shot — editable line by line before anything renders.
03
Add your characters
Add each character once with a reference image so the same face carries across every shot in the film.
04
Build the storyboard
Your script breaks into shots on a canvas. Reorder, reframe and re-prompt any shot until the board reads right.
05
Make the video clips
Turn approved storyboard pictures into video clips one shot at a time, then layer voiceover, music and sound effects.
06
Export the cut
Take the finished cut out as an MP4, MOV or WebM, up to 4K on Professional and up, 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
No tool promises it in 100% of shots. The tools that come closest send a picture of the character with every shot: Runway References, Kling Elements, Luma Ray3, Higgsfield, Google Flow Ingredients, Katalist, LTX Studio, and M Studio. For a whole film, pick one that keeps the cast in the project and sends the same reference into the video clip, such as M Studio or Katalist.
Use a clean reference image of the character (even light, neutral face), attach it to every shot, and name the character in each prompt. Write clothes into each shot's prompt. Check that the reference also goes to the video model, not only to the still.
A reference image is attached to each generation. A trained character, such as Higgsfield Soul ID, learns one person's face from 20 to 80 photos and applies it without a new upload. Higgsfield says a single reference can drift across many separate generations, and training holds the face better.
It depends on the tool. Runway Gen-4 References takes up to 3 references, Midjourney's Edit model 4, Higgsfield Popcorn 4, and Kling Video 3.0 Omni 7 (4 with a video input). In M Studio a shot holds up to 4 named people, fewer if the image model takes fewer references.
In V8, Midjourney's Edit model replaces Character Reference and Omni Reference, and takes up to 4 reference images. Omni Reference (--oref) still works on V7 and takes one image.
