AI Powered Creator Video Tool: Set Up a Short-Form Series
Six settings, in the order they lock
Short-form creators lose the most time to a decision they cannot undo. Here is what is fixed when, so you can make each choice once, on purpose.
| Setting | Where | Choices | Can it change later? |
|---|---|---|---|
| Frame | Step 1, Aspect Ratio | 16:9 Landscape (the default, marked Recommended) or 9:16 Portrait | No. It is fixed once you continue past step 1. For the other shape, start a new project with the same script. |
| Type | Step 1, Type | Short Drama (episodes up to 240 seconds), TV Series (up to 300 seconds), Film (no cap) | Not after the script is read. The price does not depend on it. |
| Dialogue language | Step 1 | One of 15; the lines are written in it from the start | Not after the read. Edit the lines, or start again with the same script. |
| Look | Step 1, Visual Style (plus Scene Style and Costume Style) | 21 visual presets; members can write their own | No. It shapes every sheet and every clip. |
| Segment length | Step 3, per episode | Standard 15s or Long take 30s | Per episode, before you generate its storyboard. Re-parsing re-cuts the episode and discards its clips. |
| Tier | The model button in the editor | From the cheapest tier up to a 2K tier | Yes, for every segment. Each segment keeps the tier it was made on. |
Everything in the first four rows is settled before the first picture is drawn; the read of your script is the first thing charged. 9:16 changes the framing the model is asked for, not just the crop: a vertical drama gets close framing that fills a phone, a landscape one gets wider staging. Setup images do not follow the frame: character sheets are always portrait and location and prop images always widescreen. Vertical or landscape and Short Drama, TV Series or Film cover the first two in full.
A drop is a row of segments, not a number of minutes
A segment is one generation, and a finished post is several of them joined end to end. At the default Standard 15s a segment runs up to 15 seconds. Long take 30s allows up to 30 seconds, but only on the tiers whose cap is 30 seconds; a 30-second segment on a 15-second tier is refused before anything is charged. The floor is 4 seconds: the editor keeps a segment's total between 4 seconds and the episode's segment length. A segment length is a ceiling, not a target, so a 60-second post is at least four 15-second segments or two 30-second ones, and usually a few more, because the story decides where a segment ends.
The price is per second either way. A 60-second post on the default tier comes to 660 credits with the joining step included, about $4.11 at the lowest credit price. What the setting changes is the size of a retake: redoing a long take costs twice a standard segment, which is why 15 seconds is the default and the safer habit when a series is on a schedule. 15-second or 30-second segments.
The type caps how long an episode may run, not how long it has to be. Short Drama splits your script so that every episode opens on a hook and ends on a reversal or an open question; the 240-second cap is the longest an episode may run. Where a post should land inside it is a pacing choice you make in the script. Writing hooks and cliffhangers into your script.
One show, many posts: how the cast carries over
A series is one project. The script is read once; the characters, locations and props are drawn once and shared by every episode, which is why a face in episode nine is the face from episode one. The order that saves money is to finish episode 1 end to end, watch it on your phone, fix any cast problem while it is cheap, and only then storyboard the rest. A problem in the cast found in episode 1 costs one regeneration; found in episode 8 it costs seven episodes of them. Making a multi-episode series.
When the story keeps going, Add an episode at the bottom of step 3 takes the continuation (pasted, uploaded, or written by AI), reads only the new pages and reuses the cast you already have. A second season or a spin-off can instead be a new project that brings characters, scenes and props over from the asset library with Pick existing: the name, description, images and voice move together, and it costs nothing on any plan. Reusing a character, scene or voice.
How many posts you can have in flight is set by how many generations run at once: 3 on a free account, 5 on Pro, 8 on Studio and 10 on Enterprise, with more above that. Extra generations queue and start by themselves. One segment takes the same time on every plan. The weekly arithmetic of that is in AI video creator: how one person plans a week.
The finishing kit for a vertical post
Short-form posts need more than the video. This is what the tool hands you for each piece, and what it leaves to you.
| Piece | What you get | Good to know |
|---|---|---|
| Cover | A poster with the title painted in, in portrait 9:16 and landscape 16:9; 3:4 (a short-drama platform cover) and 1:1 can be made from the one you pick | The first set of three is free on your first drama; each extra shape is priced as one image. Keep the title to 12 characters or fewer and check its spelling on each option; the image model draws it. |
| Music | Every episode is scored automatically once its first shot is generated and mixed under the voices | A Music switch beside the player turns it off. Turn it off before you download to get the version without music and lay your own licensed track under it. There is no track picker. |
| Captions | On accounts that have bought credits or a plan at least once, a Subtitles switch burns your script's lines into the download, and a whole episode can also export an SRT file | The text is your script's, so invented names are spelled as you wrote them. On other accounts, add captions in the platform's own editor. |
| Badge | A small SceneMixer AI mark in the bottom-right corner of the picture, plus a line of AI-generated-content metadata in the file | Free accounts always carry it. Members get clips without it by default, and the switch affects clips generated afterwards. A share link always shows it. |
| File | Download gives the full-quality original; the site's player uses a lighter copy | An episode is joined from its segments at 1 credit a second. Nothing is posted for you: you upload the file. |
Covers, music and subtitles each have their own guide: promo cover posters, the built-in score and subtitles.
Check it on a phone before you post
Your audience will watch on a phone, so check on one. The same account and projects are there when you sign in on a phone. The episode editor stacks into three views, preview, timeline and storyboard text; the model picker and badge switch sit in a bottom sheet. Download saves the original-quality file, and Share… hands it to the phone's own share menu. Play the downloaded cut full screen once before you upload it: that is the picture your viewers get. Using the site on a phone and posting to TikTok, Shorts and Reels go through the upload side.
What it does not do for a creator
It does not post. The share menu lists social sites for sending a link, but no platform receives an upload from here. It is not a timeline editor. The joined episode is made of hard cuts between segments; fades, wipes and speed ramps belong in an editor you download the file into. It does not take requests for music. The score is chosen for the episode, with no track picker and no volume control, so a trending sound or a licensed track goes on afterwards, in the platform's editor or your own. If a post needs any of those, plan for one more tool at the end.
FAQ
Can I make vertical videos for TikTok, Reels and Shorts with it?
Yes. Choose 9:16 Portrait in step 1 and every video in the project is made in that frame. The setting is fixed once you continue, so choose it before you read the script.
Can I turn a landscape project into a vertical one later?
No. The frame is fixed once you continue past step 1. Start a new project with the same script and pick 9:16 Portrait; the cast can come across from the asset library for free.
How short can a clip be?
A segment can be as short as 4 seconds. A spoken shot needs enough seconds for its line, and the editor does not check that for you.
Does a vertical video cost more than a landscape one?
No. Video is priced by the second, not by the shape of the frame.
How long can one episode be?
Short Drama episodes are capped at 240 seconds and TV Series episodes at 300; Film has no cap. An episode holds up to 60 segments. The cap is a ceiling, not a target.
Does it post to the platforms for me?
No. You download the file and upload it yourself. A SceneMixer link is fine for sending a preview, but feeds favour videos uploaded natively.
Can I keep the same characters in my next series?
Yes. In step 2 of a new project, open the card, press Edit, then Pick existing. The name, description, images and voice move over and it costs nothing.
Will my free videos carry a mark?
Yes, a small SceneMixer AI badge in the bottom-right corner of the picture, plus a line of AI-generated-content metadata in the file. Members' new clips are badge-free by default and can switch it back on; a shared link always shows it.
