One concept. Same characters, every episode.
Most AI video tools give you disconnected clips — new face, new lighting, new world every time. The Series Generator chains every segment from the previous clip's final frame, with your cast attached as references throughout. The result is a continuous series, not a slideshow of strangers.
Script planning is free · every render shows its exact price first
How it works, step by step
Six steps from an idea to a finished episode — and every episode after that reuses your cast.
- 1
Describe your series
Type a concept — a story, an AI influencer, a faceless channel format. Or upload a photo, reference image, or short video, and the cast and concept are extracted from it automatically.
- 2
Get the script, free
The AI planner turns your concept into a segment-by-segment script with a cast list. Every prompt is editable, and script generation costs nothing.
- 3
Lock your cast
Generate a reference portrait per character with GPT-Image 2.0 or Nano Banana Pro — or upload your own. Portraits are attached to every segment, which is what keeps faces, hair, and wardrobe stable across the whole series.
- 4
Render the chain
Segments render in order on Seedance 2.5. Every segment after the first continues from the previous clip's final frame, so lighting, setting, and motion stay continuous instead of resetting on each clip. Dialogue in quotes is lip-synced, with audio generated in the same pass.
- 5
Add episodes
The cast and style references carry over to new episodes — same characters, new wardrobe, new setting, new story. Leave the concept empty and the AI continues the story arc from your previous episodes by itself.
- 6
Cut and export
Trim, reorder, preview, and watermark the episode in the built-in editor, then export one finished MP4 — all in your browser, with nothing re-uploaded.
Built for series, not one-off clips
The continuity chain
Every segment after the first continues from the previous clip's final frame. No hard resets between clips — one continuous world, episode after episode.
A cast that never drifts
Reference portraits ride along on every render. The same faces, wardrobe, and style hold across segments, episodes, and even whole seasons.
Scripts written for you
The planner turns a one-line concept into a full segment script — free. Or leave the concept empty and it continues your story from the previous episodes.
Start from any media
A selfie, a character sheet, or a short clip seeds the whole project: cast and concept are extracted, and the image becomes the character's reference.
Editor built in
Trim, reorder, watermark, and export one MP4 right in the browser. Nothing re-uploads; untrimmed exports join losslessly in seconds.
Prices before you press play
Every segment shows its exact credit cost up front, and a free dry run prices the entire series without rendering a frame.
What creators build with it
Anything that needs the same characters showing up clip after clip.
Episodic shorts & faceless channels
Serialized TikTok, Reels, and YouTube content where episode 12 looks like it belongs with episode 1 — same world, same cast, new story each time.
AI influencers & brand mascots
Start from one photo, keep the same persona across every video. New wardrobe and settings per episode; identity locked by the reference portrait.
Serialized storytelling
Multi-part stories with continuity that actually holds — the planner can even write the next episode from your series so far.
Multi-part ads & product universes
Campaigns where the same spokesperson or mascot carries a message across a sequence of spots, cut and exported without leaving the browser.
Frequently Asked Questions
What is the AI Series Generator?
The Series Generator is a Flixly tool that turns one concept into a continuous, multi-episode AI video series. An AI planner writes a segment-by-segment script, image models create reference portraits for your cast, and ByteDance's Seedance 2.5 renders the segments as a chain — each clip continues from the previous clip's final frame, with your characters attached as references throughout. A built-in editor then cuts the episode into a single MP4.
How does it keep characters consistent between clips?
Two mechanisms work together. First, every character has a reference portrait that is attached to every segment, so the video model sees the same face, hair, and wardrobe on each render. Second, every segment after the first receives the previous clip as a video reference and continues from its final frame — so the world, lighting, and camera continuity carry over, not just the characters.
What models power it?
Video segments render on Seedance 2.5 (ByteDance), which supports reference images, reference video continuation, native audio generation, and lip-synced dialogue. Character portraits are generated with GPT-Image 2.0 or Nano Banana Pro — your choice. The script planner and the start-from-image analysis run on frontier language and vision models. Everything is billed through one Flixly credit balance.
Can I make a series from a photo or a video?
Yes. Upload a photo, a character reference image, or a short video, and the tool extracts the visible characters and a series concept from it. A single-person image becomes that character's reference portrait directly, so an AI influencer series can start from one selfie.
Does it generate audio and dialogue?
Yes. Seedance 2.5 generates audio — dialogue, music, and effects — in the same pass at no extra cost, and any line you put in double quotes in a segment prompt is lip-synced by the character speaking it.
How much does it cost?
Script planning is free, and you can dry-run the whole series to see the exact routing and credit price of every segment before spending anything. Segments are billed per second of output on Seedance 2.5 (480p or 720p tiers); chained segments cost slightly more because the previous clip rides along as a billed reference. The exact credit price of each segment is shown next to it before you render.
Can I edit the result without leaving the page?
Yes. The built-in final-cut editor lets you trim each clip, reorder or drop segments, preview the cut, add a text or image watermark, and export a single MP4 — all client-side in your browser. Rendered clips also stay in your Flixly history if you want to take them into your own editor instead.
What is it good for?
Anything that needs the same characters across many clips: episodic shorts and faceless channel content for TikTok, Reels, and YouTube, a recurring AI influencer or brand mascot, serialized storytelling, product universes, and multi-part ads. One project holds the whole series — cast, episodes, scripts, and renders.
