AI script generator
Start with an idea and generate a structured script with scene intent, dialogue flow, and shot logic. Keep narrative shape stable while iterating faster on visual direction.
Explore script AICast & location references
The tools that keep the same character across every shot are the ones that send a picture of the character with each shot, not only a description. M Studio does this for a whole storyboard and its video: each character has a reference image, and mentioning them with @char in a shot sends that image to the model, for the still and for the video clip. Sets work the same way with @location. Runway, Kling, Luma, Higgsfield, Katalist, and Storyboarder.ai use references too; the table below shows how each one does it.

| Tool | How you set the character | References per shot | Carries into video |
|---|---|---|---|
| M Studio | A reference image per character (uploaded photo or generated design sheet), mentioned as @char in each shot | Up to the chosen model's limit; a face is never dropped silently | Yes, on every video model it offers |
| Runway (Gen-4 References) | Tag reference images and call them with @ in the prompt | Up to 3 | Gen-4 References are an image feature |
| Kling (Elements) | An element of 2 to 4 images of one character | Up to 7 characters in video (4 with a video input), 10 in images | Yes |
| Luma (Ray3) | One character reference image | 1 | Yes, across a modified clip |
| Higgsfield | Popcorn takes up to 4 image references; a Soul ID is trained on 20 to 80 photos of one person | Up to 4 (Popcorn) | Popcorn makes sequences of up to 8 frames |
| Katalist | Cast a character once from a reference | Not stated | Yes, storyboard and video |
| Storyboarder.ai | A reference image or a written description | Not stated; no limit on characters per project | Not stated |
| StoryboardHero | Character consistency is listed as a feature | Not stated | Not stated |

Most drift comes from the model never seeing the character: each shot is a new generation from text alone. M Studio's answer is to send the picture, not only the words.
Core workflow
The tools that keep the same character across every shot are the ones that send a picture of the character with each shot, not only a description. M Studio does this for a whole storyboard and its video: each character has a reference image, and mentioning them with @char in a shot sends that image to the model, for the still and for the video clip. Sets work the same way with @location. Runway, Kling, Luma, Higgsfield, Katalist, and Storyboarder.ai use references too; the table below shows how each one does it.

Core capabilities
Upload a photo or generate a design sheet for each character. Mention them as @char in a shot's prompt and that reference goes to the model with the prompt, in the order you wrote it.
Save a set as a location plate and mention it with @location, so the kitchen in shot 12 is the kitchen from shot 3 — not a new room, and not day turned to night.
Every video model M Studio offers accepts reference images, so the @char reference travels with the still when the frame becomes a clip.
Clothes live in each shot's own prompt, not in the character's reference, so a costume change between scenes is a choice you wrote down, not drift.
All steps connect — changes in one stage cascade through your entire project without rebuilding from scratch.
Why M Studio
Script, storyboard, video, voice, and sound connect in one place, so you go from idea to final cut without switching tools.
Script, storyboard, video, voice, and sound in a single workflow — no tool switching.
Export the finished film in 4K. Video clips render at up to 1080p.
Write, direct, and narrate films end to end — scripts, dialogue, and voiceover in your language.
You own what you make — use it commercially, on YouTube or for clients.
How it works
M Studio builds a film shot by shot, and you direct every shot — this is the whole path, start to finish.
Start from a one-line brief, or import a screenplay PDF and build straight from the pages you already wrote.
Scenes, action and dialogue laid out shot by shot — editable line by line before anything renders.
Add each character once with a reference image so the same face carries across every shot in the film.
Your script breaks into shots on a canvas. Reorder, reframe and re-prompt any shot until the board reads right.
Turn approved storyboard pictures into video clips one shot at a time, then layer voiceover, music and sound effects.
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.
Consistent characters
Setup, workflow, and production use.
Tools that send a reference image with each shot. For a storyboard that becomes a film, M Studio holds each character with a reference image mentioned as @char, for the still and the video clip. Katalist and Storyboarder.ai keep a cast across a storyboard. For single shots, Runway Gen-4 References (up to 3 images), Kling Elements (up to 7 characters in a video), Luma Ray3 (one reference image), and Higgsfield Popcorn (up to 4 references) hold a character inside one generation.
Add the character to the project with a reference image — an uploaded photo or a generated design sheet. Then mention them as @char in each shot's prompt. The mention attaches the reference to that generation, for the still and for the video clip.
Yes. The same reference goes to whichever model you pick: GPT Image, Nano Banana, Seedream, Flux, or Grok Image for stills, and MiniMax H3, WAN 3.0, HappyHorse, or Gemini Omni for video. Each model reads a reference a little differently, so check the first shots after a switch.
Yes. Mention each of them in the shot. Every model has a cap on reference images; if a shot asks for more than the model accepts, location images give way first, and if the faces still do not fit, the shot is not sent until you trim the mentions or switch model.
Yes. Save the set as a location with its own image and mention it with @location in the shots that happen there. Scene lighting and time of day still come from the shot's prompt, so write them down.
No, and no AI film tool can honestly promise that. References make drift much less common, and a drifting shot can be regenerated on its own. Test it on your own script first.
