LTX Studio alternative for consistent characters: engine by engine, with the credit math
How LTX Studio and ReelDouble each keep a character the same across scenes, how many characters one render takes, and what a clip costs per second on each.

What people mean by "an LTX Studio alternative"
LTX Studio is one of the few tools built around the whole story, not one clip: you write or paste a script, it breaks it into scenes, and its Elements feature carries a character from shot to shot. That is why it turns up on almost every list next to tools like ours. The lists that rank for "LTX Studio alternative" right now are mostly vendors recommending themselves, with a sentence each and no numbers. None of them says how many characters one render can hold, which engine makes the shot, or what a second of video costs.
Those are the three things we would want to know before moving a series, so this page answers them for both sides. Where we quote LTX Studio, the figure is dated and sourced; where we quote ourselves, it comes from the rate file the studio bills from.
The short version
| LTX Studio | ReelDouble | |
|---|---|---|
| how a character is kept | Elements, reused across scenes | a character sheet plus reference images, sent to the engine on every render |
| engines | built around Lightricks' own LTX video models | Kling O3 Pro, Seedance 2.5, Seedance 2.0, Seedance 2.0 Fast, Veo 3.1 Fast; you pick per scene |
| what you pay in | computing seconds, recently renamed credits (as of 2026-10-30) | credits per second of finished video, by engine and resolution |
| price shown before render | per plan allowance | an exact credit quote under the render button |
| characters in one render | not published as a number | 3 to 30, depending on the engine |
The honest summary: LTX Studio is a storyboard-first tool with its own model underneath. ReelDouble is a studio that lets you choose the engine for each shot and tells you exactly what it costs before you press render. If you love LTX's storyboard canvas and its look suits you, the switch may not be worth it. If your problem is that a character drifts, or that you cannot predict a bill, read on.
How each one keeps a face
LTX Studio's method, from its own guide on consistent characters, is to define a character once as an Element and call it into each scene. It is a sound approach and it is the same idea most serious tools use: a fixed visual reference that travels with the prompt.
We do the same thing with one difference that matters in practice. The character's reference images go to whichever engine renders the scene, in the format that engine reads. On Kling O3 Pro the character becomes an element, written in the prompt as @Element1. On Seedance it becomes a reference image, @Image1. On Veo 3.1 Fast it is simply "image 1". You write the scene once; the studio hands the engine the reference in its own language. Our element vs image reference guide shows the syntax side by side.
The sheet that feeds all of this is made once, for 30 credits, and reused on every scene after. How we build one is in our character reference sheet guide.
How many characters one render takes
This is the number that decides whether a scene is possible at all, and it is the number we could not find published for LTX Studio. Ours, per engine:
| engine | characters in one scene | how they are passed |
|---|---|---|
| Seedance 2.5 | up to 30 | reference images |
| Seedance 2.0 | up to 9 | reference images |
| Seedance 2.0 Fast | up to 9 | reference images |
| Kling O3 Pro | up to 5 | elements |
| Veo 3.1 Fast | up to 3 | reference images |
If you name more characters than the engine takes, the studio refuses the render before anything is billed and names the roomier engine that can carry the scene. A dinner table with six people goes to Seedance; a two-hander goes wherever you like.
What a second costs
LTX Studio sells plans with a monthly allowance. As of 2026-10-30, reviews put the entry paid tier at about $15 a month for 8,640 computing seconds and the tier with commercial use at $35 a month for about 28,800, with a free tier carrying a one-time grant that sources list as 800 or 1,000 computing seconds. One review says computing seconds were recently renamed credits. Because a computing second is generation time rather than a second of finished video, the cost of one clip depends on the model, the resolution and how many tries it takes, and we could not find a published per-clip figure.
Ours is a per-second rate on the finished clip:
| engine | resolution | silent / s | voiced / s | longest clip |
|---|---|---|---|---|
| Kling O3 Pro | 720p | 24 | 30 | 30 s (two 15 s shots joined) |
| Veo 3.1 Fast | 720p or 1080p | 20 | 30 | 8 s |
| Seedance 2.0 | 480p / 720p / 1080p | 22 / 45 / 70 | same | 15 s |
| Seedance 2.0 Fast | 480p / 720p | 25 / 50 | same | 15 s |
| Seedance 2.5 | 480p / 720p / 1080p | 35 / 70 / 130 | same | 30 s (one take) |
Seedance bills by resolution, so sound on or off costs the same. Kling and Veo charge less for a silent second. Characters never change the price on any engine.
The same scene, priced on our side
A typical character scene from a story series: 12 seconds, one recurring character, a spoken line, 720p.
| engine | credits for 12 s voiced |
|---|---|
| Kling O3 Pro | 360 |
| Seedance 2.0 | 540 |
| Seedance 2.0 Fast | 600 |
| Seedance 2.5 | 840 |
| Veo 3.1 Fast | not served (8 s maximum) |
For most single-character dialogue we render on Kling at 360. When the scene needs a crowd, a long unbroken take, or Seedance's motion, we pay for Seedance and know the number before we do. Our Kling vs Seedance comparison covers when each one earns its price.
Where LTX Studio is the better fit
We would rather you pick the right tool than the one this page is on.
- You plan visually first. LTX's storyboard canvas, where the whole film is laid out as frames before any video is made, is its strongest feature. Our storyboard is a list of scenes with a shot each; it is faster to edit, but less of a mood board.
- You want one model's look everywhere. A single house model gives every shot the same texture. Choosing engines per scene gives you more control, and also more decisions.
- You are pitching, not publishing. For a client deck where the frames matter more than the motion, a storyboard-first tool fits the job.
Where we are the better fit
- You publish a series with the same face every week. The character sheet and per-engine references are built for episode two, three and ten, not just one film.
- You need to know the bill. Every render shows its exact credit cost before you press the button, and credits you buy do not expire.
- Your scenes vary. A two-person scene on Kling, a crowd on Seedance 2.5, a short voiced line on Veo: one project, three engines, one character.
- You publish vertical. Scenes are cut, captioned and exported as 9:16 MP4s in the same place.
How we would move a series over
- Export or screenshot your best frames of each character from LTX Studio: one face front-on, one three-quarter, one full body.
- Build a character sheet from those in our studio (30 credits each).
- Re-render one existing scene on Kling O3 Pro at 4 seconds voiced (120 credits) to check the face holds.
- If it holds, write the next episode as scenes and render; if not, add a reference and test again.
A free account starts with 300 credits, enough for the sheet and two 4-second voiced tests. That is the cheapest honest way to find out whether your character survives the move. You can start that test in the studio with the frames you already have.
FAQ
What is a good LTX Studio alternative for consistent characters?
ReelDouble keeps a character with a reference sheet sent to the engine on every render, and lets you pick Kling O3 Pro, Seedance or Veo per scene, with up to 30 characters in one Seedance 2.5 render.
How much does LTX Studio cost?
As of 2026-10-30, reviews list a free tier with a one-time grant, about $15 a month for 8,640 computing seconds, and $35 a month for about 28,800 with commercial use. Check LTX's own pricing page for current figures.
How many characters can be in one AI video scene?
On ReelDouble it depends on the engine: up to 30 on Seedance 2.5, 9 on Seedance 2.0 and 2.0 Fast, 5 on Kling O3 Pro and 3 on Veo 3.1 Fast.
Does using a reference character cost extra?
Not on ReelDouble. A character sheet costs 30 credits once, and after that attaching characters to a render does not change its price on any engine.
Can I move my LTX Studio characters to another tool?
Yes, if you keep clean frames of each character. Use a front, a three-quarter and a full-body image to build a new reference sheet, then test one short scene before moving the series.
