InVideo alternative for story videos: when you need the same characters in every part
InVideo builds videos from stock footage and avatars. For serialized stories with a locked cast, here is how we compare: characters per scene, Part 2, and credits per second.

What InVideo is good at
InVideo is one of the most used AI video tools for a reason. Type a prompt or paste a script and it assembles a finished video: a voiceover, a stock-footage edit cut to the script, captions, music, and if you want one, an AI avatar presenting it. For explainers, listicles, product promos and YouTube videos built on b-roll, it is fast and the stock library is enormous. Its newer plans add generative credits for AI-made shots on top of the stock edit.
We would not tell anybody making a stock-footage explainer to leave it. This page is for a different job: a story with characters, told in parts, where the same faces have to appear in every scene of Part 1 and then again in Part 2. That is the job people tend to hit InVideo's edges on, and it is the job we built our studio around.
Where the two approaches split
The difference is what a scene is made of.
In InVideo, a scene is mostly assembled: stock clips matched to the script, with an avatar as the recurring face if you use one. Its own articles describe character consistency through those AI avatars, which are presenter-style figures, built to host and talk to camera rather than to act in a story.
In our studio, a scene is generated: every shot is rendered by an engine from a prompt with your characters attached as references. There is no stock library. The face in shot 14 is the face in shot 1 because the same reference sheet went into both renders, not because a clip was found that looks close.
So the honest summary is: InVideo is an editor with a stock library and generative add-ons; we are a generator with an editor attached. Which one you want depends on whether your video is about information or about characters.
Side by side
InVideo figures are from public pricing pages and reviews, as of 2026-11-01; where InVideo does not publish a number, the cell says so.
| InVideo AI | ReelDouble | |
|---|---|---|
| what a scene is | stock footage edit, optional avatar, optional generative shots | a generated shot from a prompt plus attached characters |
| recurring character | AI avatar (presenter style) | your own character from a reference sheet, attached to every scene |
| characters in one scene | not stated | 5 on Kling O3 Pro, 3 on Veo 3.1 Fast, 9 on Seedance 2.0, 30 on Seedance 2.5 |
| a second part with the same cast | not stated | Part 2 reuses the same characters and voices |
| how a render is billed | plan credits for generative work; per-shot rates not stated | credits per second, per engine, quoted before you render |
| longest single take | not stated | 30 s in one take on Seedance 2.5; 30 s as two joined shots on Kling O3 Pro |
| stock library | yes, very large | none |
| entry price | Plus about $17 a month with 75 credits per one review checked 2026-08-16; other listings say $20 | free account with 300 credits |
InVideo prices vary between sources: one review that checked the pricing page on 2026-08-16 lists Plus at $17, Max at $85 and Generative at $170 a month, while Capterra and another guide list $20, $100 and $200 to $250 (all as of 2026-11-01). Check InVideo's own page before comparing.
The cast is the product
A story channel lives on its characters. Viewers come back for Part 2 because they want to see what happens to the same person, and the moment that person's face changes between parts, the series stops working.
That is why we put the cast first. You make each character once as a reference sheet, 30 credits each, and every scene after that names who is in it. Each engine has a hard number of characters it takes in one render, and the studio refuses a scene that names more than the engine can hold rather than quietly dropping someone:
| engine | characters per scene | credits per second, 720p |
|---|---|---|
| Kling O3 Pro | 5 | 30 voiced, 24 silent |
| Veo 3.1 Fast | 3 | 30 voiced, 20 silent |
| Seedance 2.0 | 9 | 45 |
| Seedance 2.0 Fast | 9 | 50 |
| Seedance 2.5 | 30 | 70 |
Attaching characters does not change the price on any engine. A scene with one character and a scene with five cost the same on Kling.
Part 2 then starts from the same cast. The characters and their voices carry over, so the new part is written and rendered against the same references. The story Part 2 guide walks through that.
Which engine takes which shot
Because every engine has a different strength and price, we pick the engine per shot rather than per video:
| shot type | engine we use | why |
|---|---|---|
| dialogue with up to five characters | Kling O3 Pro | cheapest voiced second, holds a cast of five |
| a crowd or a scene with six or more named characters | Seedance 2.5 | takes up to 30 references |
| a long unbroken take up to 30 s | Seedance 2.5 | one take, no join |
| short silent b-roll, no character | Veo 3.1 Fast | 20 credits a second silent |
| a 1080p hero shot up to 8 s | Veo 3.1 Fast | 1080p at the same price as 720p |
One Veo note that catches people: when you attach a character to a Veo shot, it renders and bills 8 seconds, whatever length you picked. For short character shots, Kling is usually cheaper.
What a 60-second story part costs
Here is a real shape: a 60-second Part 1, three recurring characters, built mostly on Kling O3 Pro with one Seedance shot.
| shot | engine | length | audio | credits |
|---|---|---|---|---|
| cold open, two characters | Kling O3 Pro | 8 s | voiced | 240 |
| the setup, three characters | Kling O3 Pro | 15 s | voiced | 450 |
| the chase, one long take | Seedance 2.5 | 12 s | voiced | 840 |
| aftermath, b-roll | Veo 3.1 Fast | 6 s | silent | 120 |
| the argument, three characters | Kling O3 Pro | 15 s | voiced | 450 |
| cliffhanger line | Kling O3 Pro | 4 s | voiced | 120 |
| total | 60 s | 2,220 |
With our usual retake allowance of one and a half times each shot, budget about 3,300 credits for the part. The three character sheets are 90 credits, made once and reused in every part after. Part 2 at the same shape costs the same, with no new sheets. Dropping the Seedance chase to a Kling 12-second shot would bring the part to 1,740.
We cannot put the same video through InVideo for a like-for-like credit figure, because it does not publish a per-second rate for its generative shots. That is the main reason we price per second: you can see the cost of a part before you press anything.
When InVideo is still the better pick
To be fair about it, pick InVideo over us when:
- The video is information, not characters. A listicle, an explainer, a news recap. Stock footage is faster and cheaper than generating every shot.
- You need real-world footage. Real cities, real products, real crowds. We generate everything; we have no stock library.
- You want a talking presenter reading a script. InVideo's avatars are built for that. Our characters can do it, but it is not where the studio shines.
Pick a generator with a locked cast when the video is a story, when the same characters have to come back next week, or when the look has to be consistent across every shot in a way stock clips cannot be.
Moving a story project over
If you have scripts written for InVideo, they carry over with one change: break the script into scenes of 4 to 15 seconds, one action each, and name who is in each scene. Then:
- Make a reference sheet for each recurring character.
- Paste the scenes in and pick an engine per scene from the table above.
- Check the quote; move silent b-roll to Veo and crowd scenes to Seedance 2.5.
- Render, retake the misses, cut in the editor, export a 9:16 MP4.
We set up a first story in the studio with the free 300 credits: two 4-second voiced Kling tests of the same character in two different scenes. That is the fastest way to see whether the lock holds for your cast before you move the series. Our CinemaDrop comparison and HeyGen comparison cover the same question against two other tools.
FAQ
What is a good InVideo alternative for story videos with consistent characters?
For serialized stories, ReelDouble generates every shot with your own characters attached as references, up to 5 per scene on Kling O3 Pro and 30 on Seedance 2.5, and Part 2 reuses the same cast and voices.
Can InVideo keep the same character across scenes?
InVideo offers consistency mainly through its AI avatars, which are presenter-style figures. For an acting cast that appears in every scene of a story and returns in Part 2, a reference-based generator like ReelDouble is built for that job.
How much does a 60 second AI story video cost on ReelDouble?
A 60-second part with three characters, mostly on Kling O3 Pro with one Seedance 2.5 shot, costs about 2,220 credits on ReelDouble, or about 3,300 with retakes. Swapping the Seedance shot for Kling brings it to about 1,740.
Is InVideo better for faceless explainer videos?
Often, yes. InVideo builds videos from a large stock-footage library, which is quick for explainers and listicles. ReelDouble has no stock library and generates every shot, which suits character-driven stories better.
How many characters can be in one AI video scene?
On ReelDouble it depends on the engine: Kling O3 Pro takes 5 characters in one scene, Veo 3.1 Fast 3, Seedance 2.0 and 2.0 Fast 9, and Seedance 2.5 up to 30. Adding characters does not change the price.
