How to make YouTube Shorts with AI (2026 guide)

To make YouTube Shorts with AI, write a short hook-first script, generate a vertical 9:16 video with an AI video generator that adds the voice, visuals and captions, then review it and upload it as a Short of 3 minutes or less. The whole job takes about 40 minutes per Short once your format is set, and most of that time goes into the idea and the review, not the production.

The hard part is not getting AI to make a Short. It is getting it to make a Short that people watch past the first two seconds, again and again, in a way YouTube is happy to recommend and pay for. AI handles production well; it does not pick your format, check your facts or decide what the next video should be. One example runs through every step below: Ocean Oddities, a faceless channel of 45-second animated sea-creature facts, and its first Short, "The octopus has three hearts".

What does YouTube count as a Short?

Before you generate anything, make sure the file you make is one YouTube will treat as a Short:

• Length: up to 3 minutes. Anything longer is a regular video.
• Shape: vertical (9:16) or square. A horizontal file goes to the long-form shelf.
• Resolution: YouTube accepts Shorts up to 1080p, so rendering higher only costs you more.
• Where it starts: a Short is shown in a swipe feed, so the first frame and first line decide whether it is watched at all.

Three minutes is a ceiling, not a target. Most faceless fact and story Shorts land between 30 and 60 seconds, because a shorter video is easier to finish and to rewatch.

The example: Ocean Oddities

Ocean Oddities posts one strange sea-creature fact per Short, five days a week. Each video is 45 seconds, 9:16, in a warm 3D cartoon style so the animals look friendly rather than gory, with a calm narrator and bold white captions.

The first Short explains that an octopus has three hearts: two pump blood through its gills and one pumps it around the body, and that body heart pauses when the octopus swims. Everything below is the production plan for that Short and the four that follow it.

Step 1: Pick a format you can repeat 50 times

A Short is easier to make than a long video, which means you will need many more of them. Choose the format before the first topic: one promise, one length, one look and one voice that every video shares.

Write 30 topics in one sitting. If you stall before 30, the format is too narrow for daily posting. Ocean Oddities passed 30 in fifteen minutes (the mantis shrimp punch, the immortal jellyfish, the fish that walks on its fins, the shark older than trees).

Step 2: Write a 110-word script with the hook first

A calm narrator reads about two and a half words per second, so a 45-second Short holds roughly 110 words. Write to that budget, and put the most surprising claim in the very first line instead of an introduction.

Structure the script in beats, with a visual note next to each line:

• 0:00 to 0:03, the hook: "This octopus has three hearts, and one of them stops when it swims." (Visual: a cartoon octopus with three glowing hearts.)
• 0:03 to 0:20, the explanation: two hearts push blood through the gills, the third sends it to the rest of the body. (Visual: the octopus breathing at its rock, hearts pulsing in turn.)
• 0:20 to 0:38, the twist: when it swims, the body heart pauses, which is why octopuses prefer to crawl. (Visual: the octopus jetting away, then crawling slowly along the sand.)
• 0:38 to 0:45, the loop: "So next time you see one crawling, it's not lazy. It's saving a heartbeat." (Visual: the octopus waving from its den.)

Check every fact against one reliable source before you generate. A narrator saying something wrong with total confidence is the fastest way to lose trust in the comments. Our faceless video script guide goes deeper on hooks and loops.

Step 3: Generate the Short with AI

Production is where AI saves the most time: the voice, the scenes, the captions and the music come back as one file.

1. ClipNova is the complete option. For Ocean Oddities:

1. Open Prompt to Video and paste the idea or the full script.
2. Set the format to 9:16.
3. Pick the Disney / Pixar 3D style so every scene shares the warm cartoon look.
4. Choose AI Video for full animation, or Moving AI Images for a cheaper animated-picture look on fact Shorts.
5. Keep narration on and pick one narrator voice; save it as the channel's voice. Narration is available in 18 languages if you later run the channel in Spanish or Portuguese.
6. Turn captions on and choose the Speech style (white, all caps, heavy outline), which reads well on a small screen.
7. Leave the length on auto so the video fits the narration, or set 45 seconds.
8. Check the credit estimate, then generate.

Videos can run up to 5 minutes, so the same settings work if a topic later deserves a longer cut. Plans from $19/mo.

Step 4: Review every Short before it goes live

AI gets most scenes right and a few slightly wrong. A five-minute review is what separates a channel from a content farm.

Watch the Short twice, once with sound and once muted:

• Facts: does the narration match your checked script, word for word on numbers and names?
• Captions: are they in sync, spelled correctly and inside the safe area, clear of the like and comment buttons on the right?
• Scenes: does each scene show what the line says? For Ocean Oddities, a heart count of four in one frame would undo the whole video.
• First frame: does it work as a thumbnail in the feed?

Step 5: Upload it as a Short with the right settings

From a computer, open YouTube Studio, click Create, then Upload videos, and select the vertical file. A vertical or square video of 3 minutes or less is treated as a Short.

• Title: the curiosity, not the answer: "The Octopus Has 3 Hearts (One Stops)". Keep it short enough to read at a glance in the feed.
• Description: one or two sentences restating the fact, plus two or three relevant hashtags.
• Audience: answer "made for kids" honestly. A cartoon style alone does not make a video made for kids; YouTube looks at who the video is aimed at. Ocean Oddities is a general-audience channel.
• Altered or synthetic content: YouTube asks for this label on realistic AI content that could mislead viewers. A clearly animated cartoon octopus does not need it; a realistic-looking fake news clip would.

Post at the same times every day so viewers and the algorithm learn your rhythm.

Step 6: Read the numbers and make the next Short

After 48 hours, open YouTube Studio analytics for the Short and look at two figures:

• Viewed vs. swiped away: the share of people in the Shorts feed who stayed to watch. If it is low, the first line or first frame failed; rewrite the hook for the next video.
• Average percentage viewed: if people leave in the middle, the explanation is too slow; cut words.

Then make the next one. Ocean Oddities turns its best performer into a mini-series ("3 animals with more than one heart, part 1") and keeps the same voice, style and caption look for every episode. When a topic clearly holds attention, remake it as a longer horizontal video for the main channel.

Remember YouTube's rules on repetitive content: AI-made Shorts are allowed, but channels that upload near-identical, mass-produced videos are not eligible for monetization. A new fact, a new angle and a reviewed script in every video keep you on the right side of that line.

How long does it take?

For one 45-second Short like "The octopus has three hearts", once the format and settings exist:

• Topic and fact check: 10 minutes
• Script: 10 minutes, or edit an AI first draft
• Generation: one run, done while you research the next topic
• Review and fixes: 5 to 10 minutes
• Title, upload and settings: 5 minutes

That is about 40 minutes per Short, or five Shorts in one afternoon if you batch them. Choosing the format, voice and style happens once. Plans from $19/mo, with every feature included; only the monthly credits change.

What goes wrong, and the fix

• A slow first line. "Today we're talking about octopuses" loses the swipe. Open with the claim that sounds wrong.
• Too many words. A 45-second Short with 160 words forces a rushed narrator. Stay near 110 words, or make the video longer.
• A new look every video. Changing style, voice or captions weekly makes the channel unrecognizable. Save your settings and reuse them.
• Unchecked facts. AI narration says wrong numbers with confidence. Check every figure against one source before generating.
• Captions under the buttons. Captions hidden by YouTube's on-screen buttons are unreadable on mute. Check placement on a phone.
• Near-identical uploads. Swapping the animal into the same script is the kind of repetition YouTube does not monetize. Give each Short its own angle.
• Judging the format after five videos. Most Shorts channels need several weeks of daily posts before the numbers mean much. Commit to 30 Shorts before you change course.
