Short answer
Write a hook and a short script, generate vertical (9:16) clips in the KreatorFlow video studio, add a voiceover and captions in the editor, export in 9:16 and upload the file to YouTube yourself. A 30-second Short made from 2 clips of 15 seconds on Seedance 2.0 Mini costs 50 credits at 720p, shown before you generate. Shorts can run up to three minutes; keep each one to a single idea.

Make a Short, step by step
- 1
Write the hook first
Open the free hook generator, pick YouTube Shorts as the platform and describe your topic. It returns 10 labelled hooks, each with a spoken line and on-screen text. Pick the one you would stop scrolling for; the first second decides whether people swipe away.
- 2
Turn it into a timed script
The free script generator writes a timed script for 15, 30 and 60 seconds, with a caption and hashtags. For a 20 to 30 second Short, take the 30-second version and cut what does not earn its place. Split the script into shots of a few seconds each.

Generate vertical (9:16) clips
In the video studio, pick a Seedance model, set the aspect ratio to 9:16 and describe one shot per generation. Clips run 4 to 15 seconds on Seedance 2.0 and up to 30 seconds on Seedance 2.5, which can cover a whole Short in one clip. Add the same reference image to every shot (up to 9 image references) so the character or product looks the same from clip to clip.

Add a voiceover
Paste the script into Text to Speech in the Audio studio and pick one of 45 voices in 14 languages. It costs 2 credits per 1,000 characters, charged in whole 1,000-character blocks, and a 30-second script usually fits in one block.

Edit, caption and export in 9:16
Open the editor, import the clips and the voiceover, trim the slow parts and put a hook title on the first shot. Auto captions turn the speech into timed text in Clean, Outline, Pop or Glow styles, or import an SRT or VTT file. Export as 9:16 at 24, 30, 60 fps; the free plan exports up to 1 min at 1080p.

Check it before you post
Upload the exported Short to Kiryu and say it is a YouTube Short. It watches the video and returns timestamped notes on the hook, pacing, captions, audio and platform fit, with the top fixes. You get 1 free video review a day. Then upload the file in the YouTube app or YouTube Studio.
What a 30-second Short costs
Credits from the same code the studio charges with. Each model row covers 30 seconds of video with the fewest clips that model allows. 1080p is on Pro, Max and Business.
| Item | 720p | 1080p |
|---|---|---|
| Seedance 2.0: 2 clips of 15 seconds (30 s) | 90 credits | 180 credits |
| Seedance 2 Fast: 2 clips of 15 seconds (30 s) | 72 credits | 120 credits |
| Seedance 2.0 Mini: 2 clips of 15 seconds (30 s) | 50 credits | 100 credits |
| Seedance 2.5: one 30-second clip (30 s) | 140 credits | 300 credits |
| Voiceover (Text to Speech), per 1,000 characters of script | 2 credits | Same |
| Auto captions on a paid plan, per started minute | 1 credit | Same |
| Auto captions on the free plan | 3 tries a month, up to 60 s each | Same |
| Editor export (free plan) | 5 a month, up to 1 min, 1080p, small KreatorFlow mark | Same |
| Kiryu review of the finished Short | 1 free video review a day | Same |
Worked example: 2 clips of 15 seconds on Seedance 2.0 Mini at 720p, one voiceover block and one minute of auto captions comes to 53 credits. Failed generations give their credits back automatically. Plans start at $15 for the first month on Creator, and credit packs from $8.
What a YouTube Short needs
A Short is a vertical video, up to three minutes long since YouTube raised the limit in October 2024. Generate in 9:16 from the start rather than cropping a landscape clip, so the subject stays centred and nothing important falls under the title, the buttons or the caption bar.
Shorter is usually easier to hold. A 20 to 30 second Short with one clear idea, a hook in the first second and a payoff at the end gives viewers a reason to watch to the end and, ideally, to watch it again.
- Shape: 9:16, full frame, subject in the middle third.
- Hook: something moving or surprising in the first second, plus the hook as on-screen text.
- Captions: big, short lines, because many people watch with the sound off.
- Ending: a payoff or a clean cut back to the opening shot, so the loop feels natural.
Prompts that work for vertical shots
Write each shot as one sentence of who or what is in frame, one action, the light and one camera move. Say "vertical" and keep the subject close: wide establishing shots lose detail on a phone screen.
Keep text out of the generated scene. Titles, numbers and captions come out exact when you add them in the editor, and slightly wrong when a model draws them.
Example hook shot
Close-up of a barista sliding a latte across a wooden counter toward the camera, the foam art is a tiny cat face, warm morning window light, slow push-in, vertical 9:16.
Shorts without showing your face
Most AI Shorts channels are faceless: generated scenes, a voiceover and captions, with no presenter. Everything in the steps above works that way. For a cartoon channel with a recurring character, Kartoonz turns one idea into a finished, captioned cartoon; the faceless cartoon channel guide covers niches, posting rhythm and YouTube's monetization rules.
If you want a talking presenter without filming yourself, Lip Sync makes a photo or a character speak a voiceover line. Use only faces you own or have permission to use.
What KreatorFlow does not do (and the honest alternatives)
KreatorFlow makes and edits the video; it does not run your channel. Here is where you will need YouTube itself or another tool.
- It does not upload or schedule to YouTube. You download the export and post it in the YouTube app or YouTube Studio, where you also set the title, description and AI disclosure.
- It does not read your channel analytics. Retention graphs and swipe-away rates live in YouTube Studio; Kiryu reviews the video file itself, so check Studio first and tell Kiryu what you saw.
- One clip is not a whole Short on every model. Seedance 2.0 clips stop at 15 seconds, so a longer Short is several clips joined in the editor; Seedance 2.5 goes up to 30 seconds in one clip.
- The free editor exports up to 1 min with a small KreatorFlow mark. Shorts longer than that need a paid plan (Creator exports up to 10 min).
- 1080p and 4K generation is on Pro, Max and Business. On other plans, generate at 720p.
- Each generation is a new take. Faces, products and small details can drift between clips; reuse the same reference image and check every shot.
- If you already film yourself and only need cuts and captions, a phone editor or YouTube's own Shorts camera may be all you need.
Keep it original and labelled
YouTube only monetizes original, authentic content, and mass-produced or near-identical uploads can be refused. Give every Short its own idea and script, and use the same character and style so the channel has an identity.
Label realistic AI-generated content where YouTube asks you to, and only show real people's faces or voices with their permission.
Frequently asked questions
Can AI make a YouTube Short for me?
Yes, in pieces you control. AI writes the hook and script (free hook and script generators), Seedance generates the vertical (9:16) clips, Text to Speech reads the voiceover, and the editor adds captions and exports the Short. You choose the idea, check each shot and upload it yourself.
What aspect ratio should a YouTube Short be?
Vertical 9:16. Pick it in the video studio before you generate and export as 9:16 in the editor, rather than cropping a landscape clip.
How long can a YouTube Short be?
Up to three minutes since October 2024, though most work best at 20 to 60 seconds. Seedance 2.0 clips run 4 to 15 seconds and Seedance 2.5 clips up to 30 seconds, so join clips in the editor for a longer Short. The free editor exports up to 1 min.
How much does it cost to make a YouTube Short with AI?
A 30-second Short made from 2 clips of 15 seconds on Seedance 2.0 Mini costs 50 credits at 720p. A voiceover adds 2 credits per 1,000 characters. Captions on a paid plan are 1 credit per started minute. The studio shows the cost before every generation.
How do I add captions to a YouTube Short?
In the editor, open Captions and choose Auto captions, or import an SRT or VTT file. Free accounts get 3 auto caption tries a month on videos up to 60 seconds; paid plans use 1 credit per started minute. SRT and VTT import is free.
Can I make faceless YouTube Shorts with AI?
Yes. Generated scenes, a voiceover and captions need no presenter. For a recurring cartoon character, Kartoonz makes finished, captioned cartoons; the faceless cartoon channel guide explains how to run that kind of channel.
