How to Create YouTube Shorts From Scratch, Step by Step

What does creating a YouTube Short from scratch mean?

It means the video does not exist yet in any form. You are not trimming a long video into clips or re-cutting someone else's footage: every part is made new. That matters for two reasons. Nothing in the video can be claimed by another channel, and YouTube's monetization policies reward original work over reused material.

Shorts are worth the effort: YouTube said in June 2025 that Shorts average more than 200 billion views a day. There are three ways to make one from nothing. You can film it with the Shorts camera in the YouTube app, which records in segments up to three minutes in total. You can edit it yourself from stock clips, recorded narration and music. Or you can generate it: an AI video tool writes the script, voices it, makes the scenes and adds captions from a sentence you type. The steps below are the same whichever route you take; only who does the work changes.

YouTube Shorts specs to build for in 2026

Get these right before you make anything. A video that misses them is published as a regular video instead of a Short, or loses its edges in the feed.

• Shape: vertical 9:16, 1080×1920 pixels. YouTube also counts square videos as Shorts.
• Length: up to three minutes since 15 October 2024. Most Shorts that hold viewers run 20 to 60 seconds.
• Resolution: YouTube's Shorts help page gives 1080p as the maximum for uploaded Shorts, so there is nothing to gain from exporting larger.
• Title: up to 100 characters. The first few words are what the feed shows, so put the subject there.
• Music: most songs can be used for up to 90 seconds in a Short of up to three minutes; some tracks are limited to 60 or 30 seconds.
• Copyright: since 24 September 2026, a Short between one and three minutes long with an active Content ID claim is no longer blocked automatically, but a claim still affects what it can earn. Music and clips you have the rights to avoid the question.

Step 1: Pick an idea people are already looking for

A Short carries one idea. Pick a question people in your niche keep asking, a surprising fact, a before and after, or a story with a single turn in it. Good places to look: the suggestions YouTube's search box offers as you type, the comments under the most-watched videos in your niche, and Google Trends.

Write the idea as one sentence you could say out loud, such as "why octopuses have three hearts". If it takes two sentences, it is two Shorts.

Step 2: Write the hook first

In the Shorts feed a viewer decides within a second or two whether to watch or swipe. YouTube Studio measures exactly that: for every Short it shows how often viewers chose to watch it versus swiping away. Open on the most surprising claim, the question or the moment of stakes, and give the context after.

Compare "An octopus has three hearts, and one of them stops beating when it swims" with "Today we are going to learn about octopuses". The first line is the reason to stay; the second spends the only seconds that matter on nothing.

Step 3: Script it to the second

Narration runs at about two and a half words a second, so a 30-second Short holds roughly 75 words and a 60-second one about 150. Write for the ear: short sentences, one fact each, nothing that sounds like a list read aloud.

A structure that works for most topics:

• First two seconds: the hook.
• Next fifteen or so: the payoff, the reason the hook is true.
• Then one or two details that make it memorable.
• Last line: an answer, a twist, or a line that leads back into the first, so the replay feels natural.

Step 4: Give it a voice

Record the narration yourself on a phone in a quiet room, or use an AI voice. Either way, keep one pace and one tone across the channel: viewers come back to a voice they recognize.

An AI voice is a production tool, like a microphone. What YouTube's policies look at is whether the script, the choices and the result are yours, not which tool read the words.

Step 5: Put a moving picture under every line

A Short whose picture changes with each sentence holds attention better than one still image with a slow zoom. Plan one shot per line: what the viewer sees while that line is said. For "one of them stops beating when it swims", show the octopus pushing off, not a diagram of a heart.

You can film the shots, use licensed stock clips, or generate them as AI video, where every scene is made for the line it sits under and characters look the same from shot to shot. Pick one look per Short: a cartoon, then stock footage, then a still photo reads as unfinished.

If a scene shows realistic people, places or events that did not happen, answer Yes to AI use (altered or synthetic content) in YouTube Studio when you upload. Animated or clearly unreal scenes do not need it.

Step 6: Add captions and sound

Burn the captions into the picture. Many people scroll the feed with the sound off, and captions in the picture look the same on every phone. Time them to the words, show a few words at a time, and keep them out of the bottom fifth of the frame, where the Shorts screen puts the title, the buttons and the channel name.

Keep the music well under the voice, and use tracks you have the rights to: YouTube's own audio library, or music made for your video.

Step 7: Export and upload

Export an MP4 at 1080×1920. Upload it with the YouTube app or with YouTube Studio on a computer: a square or vertical video of up to three minutes is categorized as a Short.

Give it a title that names the subject in the first words, a one-line description and a few hashtags that describe the topic. After a day or two, look at how many viewers chose to watch it rather than swipe away: when that share is low, the first line is what to change in the next Short.

How long does it take to make a Short from scratch?

By hand, a 30-second Short with narration and captions usually takes one to three hours: the idea and the script, recording and cleaning the voice, finding or filming a shot for every line, editing, and timing the captions. The first few take longer.

With an AI video generator the time goes into the idea and the decisions, and the making takes minutes: the tool writes the draft, voices it, makes the scenes and syncs the captions, and you review and change what you want before it is made.

How to create a Short from scratch with FacelessCast

FacelessCast is built for exactly this: a finished Short from one sentence, with no camera and no footage. The whole process, as it works today:

• Type the idea in the studio the way you would say it to a person, for example: "A 30-second Short on why octopuses have three hearts, with captions".
• The studio plans it with you: the length, the voice, the look, whether you want captions. It asks only about what you did not say.
• You see the plan and the exact price before anything starts. Planning is free, and so is a storyboard that shows every scene before the video is made.
• Press Accept and start. The studio writes a hook-first script, reads it with a narrator that fits, makes every scene as AI video, syncs the captions to the words and adds music.
• Download the MP4, 1080×1920 with no watermark, and upload it to YouTube Shorts, TikTok or Instagram Reels.

Rules to know before you publish

Faceless and AI-made Shorts can earn money. What YouTube does not pay for is content that is mass-produced, repetitive, or reused with nothing added; since 15 July 2025 that rule is called inauthentic content. Give every Short its own idea, script and pictures, and it is judged like any other video.

To join the YouTube Partner Program through Shorts you now need 1,000 subscribers and 10 million qualified Shorts views in the last 90 days. From 1 February 2027 new applicants need 1,000 subscribers and either 20 million qualified Shorts views in 90 days or 8,000 watch hours in a year, and earning from the Shorts feed will need 10 million qualified Shorts views in the trailing 90 days.
