AI Long Story Video Generator

Quick answer: A long story video is not one long generation. SceneMixer builds it from segments of up to 15 or 30 seconds, up to 60 per episode, each generated from the same character and place drawings and joined into one file. That makes 5 minutes one episode, and 30 minutes a run of episodes or sequences. The cost is the finished seconds at 10 credits a second on the default tier; the storyboard that plans it is free to read and edit.

How a long story is planned

Story length	Segments (15 s / 30 s)	How to build it
5 minutes	20 / 10	One TV Series episode
10 minutes	40 / 20	Two TV Series episodes (up to 300 seconds each), or three Short Drama episodes
20 minutes	80 / 40	Four to five episodes of one story
30 minutes	120 / 60	A series of episodes or Film sequences

Short Drama episodes run up to 240 seconds and TV Series up to 300, so a story longer than that is cut into numbered parts that share one cast. How length is built · A 5-minute video.

Make the length a story, not a stretch

Give every part a turn. A 20-minute story as five 4-minute parts needs five small reversals, not one long middle.
End parts on a question. It makes the next one click. Hooks and cliffhangers.
Keep the cast small and the places few. That is what makes a long story steady and affordable.
Let a voice carry the gaps. A voice-over line covers a time skip better than a shot.

Generate a long run without watching it

Segments render on the server, so you can queue many at once, up to your plan's limit, and close the page. When they are done, join the episode. Episodes can be storyboarded and rendered in any order, and a single weak shot is regenerated on its own. Segment versions · Why a long story stays consistent.

Where long stories are posted

A 10 to 20 minute story fits a YouTube channel; the same story cut into 1 to 3 minute parts fits Shorts and Reels in 9:16. Decide before the script is read: the format is fixed in Step 1. A faceless YouTube channel · Vertical video.

Cost, plainly

Ten minutes is 600 seconds of video: that many seconds at 10 credits a second on the default tier, plus 1 credit a second to join, plus a little for retakes. A series of ten 90-second episodes from a 30,000-character novel comes to about 10,026 credits, about $62 at the lowest credit price. Spending fewer credits.

In SceneMixer vs. stitching tools together

Most AI drama workflows are five or six tools in a row. This is where each step happens here, and what it replaces.

Step	In SceneMixer	Doing it by hand with separate tools
Script and episode plan	Paste a script or a novel, or type one line: it is read into a cast, locations, props and an episode outline you can edit	A chat model writes the script; you split it into episodes and carry the text from tool to tool
Character faces and places	Every character, location and prop is drawn once as a reference sheet and attached to every shot it appears in	An image model, one sheet at a time; you upload the right reference to every clip yourself
Shots	A storyboard per episode with numbered shots and seconds; video is generated segment by segment in 9:16 or 16:9 against the same sheets	A video model, one clip per prompt, describing the same people again each time
Voices and dialogue	Lines are performed in the video itself, one voice per character, in any of 15 languages	A text-to-speech tool for each line, then a lip-sync pass on every clip
Fixing one shot	Edit that shot's text and regenerate the segment alone; the rest of the episode is untouched	Regenerate the clip, then re-cut the timeline
Finishing	Segments are composited into one episode file with its score; members download without the AI badge	A video editor to join the clips, add music and captions, then export
Publishing	You upload the finished episode to TikTok, YouTube, Instagram or anywhere else; nothing is posted for you	Upload by hand, the same as here
