How to Make TikTok Videos With AI

To make a TikTok video with AI, write a short, conversational script with the hook in the first line, generate it as a vertical 9:16 video with AI narration, word-by-word captions and music, check that the captions sit clear of TikTok's on-screen buttons, then post several hook variations and keep the shape that holds viewers.

That is the whole process. The rest of this guide is the detail that decides whether a TikTok gets watched or swiped: how the platform differs from YouTube Shorts, how to write for it, which Vidcru format to use for which kind of video, and how to learn from what you post.

How TikTok differs from YouTube Shorts

TikTok and YouTube Shorts share an aspect ratio and not much else. The same video can perform very differently on each, because the audiences arrive with different expectations.

Polish can work against you. TikTok's native register is informal and direct. Content that looks like a brand campaign reads as advertising, and viewers have learned to swipe past advertising. On YouTube, production value is closer to neutral.

Sound matters more. Narration, music and the rhythm of the voice carry a lot of weight on TikTok, so choose the voice as carefully as the visuals. Still make every video work with the sound off.

The comment section is part of the content. Videos that give people something to reply to tend to travel further than videos that only inform. A clear opinion, a ranking, or a question at the end is a real strategy.

Feedback comes quickly. TikTok tends to give a video its verdict fast. You learn sooner, which means you can run more experiments per week.

How to make a TikTok video with AI, step by step

1. Write for the feed, not for the brand

The most common failure is writing TikTok copy in brand voice. The register is conversational, direct, and often a little abrupt. Compare:

The second is a person talking. That is the whole difference.

2. Put the hook in the first second

The opening frame and the opening words decide whether someone stays. What works: an unexpected statement, a visible result, a direct question, or a mid-action opening that implies the viewer missed something. What does not: logos, intros, slow builds, and anything that looks like a title card.

3. Cut the script to length

Narration runs at roughly 130 to 160 spoken words per minute, so a 30-second TikTok is about 70 to 80 words and a 60-second one about 140. Most first drafts are twice that. Count the words and cut to the number; rushed narration makes captions impossible to follow.

Make one point per video. If you have three points, that is three TikToks. Short, concrete sentences also produce better scenes, because the agent builds visuals from each beat of the script; how scene breakdown works explains why.

4. Choose the format that matches the content

Vidcru has four ways to make a video. Three of them produce vertical 9:16 video for TikTok:

• Story, fact, history or list content: AI Images. Every scene gets a newly generated image with camera movement, in an art direction you pick from dozens of styles. It is the format behind a lot of faceless storytelling.
• A repeatable series without a presenter, such as how-tos, comparisons or quizzes: an Agentic Video Shorts template. Shorts run up to 90 seconds, and every post in the series shares one animated look.
• You on camera, for recommendations, advice or anything where a real face builds trust: film it on your phone and upload it to Edit Your Video, which cuts, captions and scores the recording for you.

Agentic Character Video, where your own character stars in every scene, is 16:9 only, so it suits YouTube and LinkedIn rather than TikTok.

5. Pick the voice and caption style

Choose from 30 AI voices, with narration available in many languages. Pick a voice that sounds like someone your audience would actually listen to, and keep it consistent across a series so the account has a recognizable sound. Then choose a caption style; captions are word-by-word, which suits viewers who watch with the sound off.

6. Preview against TikTok's interface

TikTok's interface covers a lot of the frame: the caption and username at the bottom, the sound ticker, and the button rail on the right. Before exporting, watch the preview and check that captions sit in the central band, away from the right edge and the bottom of the screen. Text sitting under the follow button is the most common avoidable mistake in short-form video.

7. Export and post it yourself

Download the MP4 in Full HD 1080p and upload it through TikTok as you would any video. Vidcru does not post to social platforms for you, which also means you write the TikTok caption and choose hashtags in the app. Finished videos stay in your History for 30 days, so you can come back and download them again.

If you add a sound from TikTok's library on top, check that the narration is still clearly audible; the exported video already has its own music bed.

Test hooks in batches, not single videos

TikTok performance varies a lot from video to video, and single-video conclusions are close to meaningless. Judge in batches.

A reasonable experiment:

1. Pick one idea and write ten different opening lines for it.
2. Generate all ten with the same body, voice and template.
3. Post them over two weeks.
4. Look at which openings kept people watching past the first few seconds.
5. Write the next batch around the shape of the winners: not the topic, the shape of the opening.

This is only affordable when a variation is cheap to make, which is the practical argument for AI-generated short-form: the limit moves from production time to how fast you can read results.

TikTok video ideas that suit AI generation

Some formats work well when nobody is on camera:

• Little-known stories, such as history, mysteries or biographies, told in 45 to 90 seconds with AI Images.
• "Three things nobody tells you about..." list videos in your niche.
• Myth versus fact videos, where the hook states the myth.
• Quick how-tos with numbered steps on screen.
• Rankings and comparisons, which invite people to disagree in the comments.

Formats that need a real person, such as reviews, testimonials and personal advice, are better filmed and run through Edit Your Video than generated.

Labeling AI-generated content

Platform rules on AI-generated and synthetic media keep changing, and they differ by platform and country. TikTok asks creators to label some kinds of AI-generated content; check its current rules before you post, especially for commercial content, and treat compliance as your responsibility rather than the tool's. The risk falls on your account.

A checklist before posting

• Does it sound like a person, not a brand?
• Does the first second give a reason to stay?
• Is the script one point, cut to length?
• Are captions clear of the right rail and the bottom of the frame?
• Does it work with the sound on and with it off?
• Is there something a viewer might reply to?

Common questions

How long should an AI TikTok video be?

Long enough to make one point and no longer. For most topics that is 20 to 60 seconds. Vidcru's Shorts templates go up to 90 seconds, which covers almost every short story or explainer.

Do I need to show my face?

No. AI Images and Agentic Video Shorts make complete videos without anyone on camera. A real face helps most with advice and recommendations, where credibility drives the follow.

What does it cost?

Vidcru uses one-time credit packs with no subscription. Every video shows its credit estimate before you create it, and a failed video's credits are refunded. See pricing, or the pricing guide for how costs add up over a batch.

Write one script, cut it to 60 seconds, and generate it in Agentic Video Shorts. Then write four more hooks for the same idea.
