How to make AI videos for TikTok step by step, with real times

Every tool page ranking for this search says the same thing: type an idea, click generate, post a TikTok in five minutes. Then you try it and the result looks like every other AI video on the For You page, the character changes face halfway through, and you have spent an afternoon on 30 seconds of footage.

The five minute version exists, but it is not what gets watched. What gets watched is a short, specific story with a strong first second, built from clips you chose on purpose. That takes longer, and nobody tells you how much longer.

This guide walks through the full workflow in seven steps, with an honest time range for each one, for a beginner making a 20 to 40 second video. The short version: about 3 to 5 hours for your first video, and 60 to 90 minutes per video once your setup is done.

What are the steps to make an AI TikTok video?

There are seven steps: idea, script, look, clips, voice, edit, post. The table shows each one with the time a beginner should plan for, first video versus a settled routine. These are planning ranges, not guarantees; slow generation queues and retries move them.

The step that shrinks most is step 3: you do it once and reuse it for every video in the series. The step that never gets fast is step 4, because generation is where retries happen.

For comparison, one r/artificial poster running a heavily automated channel said they spent about 3 hours a week on creation for a daily cadence. That is what a mature, templated pipeline looks like, not week one.

Step 1: How do you pick an idea that works for AI video?

Pick a single story or topic with a payoff you can show in under 40 seconds. AI video is good at dramatic visuals and stylised characters and bad at subtle realism, so favour stories with a clear twist, reveal or reaction.

Good starting sources:

1. Reddit story threads (relationship drama, workplace revenge, "am I wrong" posts). Read the comments: the reply everyone upvoted is often the payoff.
2. Your own comments once you have a few videos up. Requests for "part 2" are free ideas.
3. A repeatable series format such as one character in a new situation each episode, so step 3 pays off.

Rewrite the story; do not read someone's post word for word. Write down the payoff in one sentence before you move on. If you cannot, the idea is not ready.

Step 2: How do you write a script for an AI TikTok?

Write 20 to 40 seconds of script, about 60 to 110 spoken words, with the hook as the very first line and the story split into numbered beats. Each beat becomes one clip, which makes step 4 a checklist instead of guesswork.

A simple structure:

HOOK (0 to 2s): the most surprising line, said first
BEAT 1: who and where, one sentence
BEAT 2: the problem
BEAT 3: the turn
PAYOFF: the line people will quote in the comments

You can draft with ChatGPT or Claude, but edit it out loud. If a line takes more than one breath, cut it. Dialogue usually holds attention better than narration, and short, quotable payoffs get shared.

Step 3: How do you keep the look and characters consistent?

Lock the style and your main character before you generate a single clip. Make one reference image of the character, generate it from a few angles, and reuse the same style words and reference images in every prompt.

This is the step tool pages skip and the one Reddit complains about most. In an r/aitubers workflow thread, the recurring questions were how to keep shots consistent from clip to clip and why characters react strangely. A reply in another thread summed up the fix: lock the visual style first and favour style over volume.

What to save in your project folder

• One style line you paste into every prompt (lighting, palette, camera)
• Character reference images: front, side, three quarter
• A short description of each character's face, hair and clothes
• The music and caption style you will reuse

It takes 45 to 90 minutes the first time. After that, it costs nothing per video, which is why series formats get faster.

Step 4: How do you generate the clips?

Generate one clip per beat, 4 to 8 seconds each, image to video where you can, using your reference image as the first frame. For a 30 second video that is 5 to 8 clips, and you should budget two takes per clip.

1. Turn each beat into a short shot description: subject, action, camera, setting, mood.
2. Start each clip from a still that already looks right, rather than text alone.
3. Generate, watch the whole clip, and keep it only if the face, hands and action hold up.
4. When a clip fails, change one thing per retry (the action, the camera, or the length), not the whole prompt.
5. End clips on a frame that cuts cleanly into the next one.

Clip length matters. Several r/aitubers creators described the same habit: keep clips brief, chain them, and keep editing light. Short clips are cheaper to retry and break less often.

Watch out: retries are where both the time and the money go. Our AI video cost per month breakdown works out that a 40 second Short built from premium clips costs about $11 once two takes per clip are counted. For prompt patterns that cut retries, see the best prompts for AI video generators.

The AI Videos pack covers this step in the most depth: JSON shot lists, a prompt checker that runs before you spend credits, and how to end clips so they join cleanly.

Step 5: How do you add voice and sound?

Add the voice after the clips, then fit the edit to the voice, not the other way round. Use an AI voice tool or record your own, keep one voice per character for the whole series, and add quiet music under it.

Some video models now generate dialogue and sound inside the clip. That saves time when it works, but check the words: dropped or garbled lines are a common failure, so keep the script beside you when you review.

Step 6: How do you edit an AI video for TikTok?

Edit in CapCut (or any editor) at 9:16: put the hook clip first, trim every clip to its best second or two of motion, add burned-in captions, and export at 1080 by 1920. Fast pacing hides small AI glitches; long, slow shots expose them.

A quick editing checklist:

• First frame is already moving and already interesting
• No clip runs longer than it needs to; cut on action
• Captions large, inside the safe area, away from the right side buttons
• Sound levels even, voice clearly above music
• Watch it once on your phone, muted, then once with sound

Tip: creators in r/AI_UGC_Marketing reported that videos edited heavily before upload seemed more likely to be labelled as AI. That is not something to work around: label honestly in step 7 and let the content carry it.

Step 7: How do you post an AI video on TikTok?

Upload the 9:16 file, write a short caption that adds context or a question, pick a cover frame, and turn on the AI-generated content setting under More options before you tap Post. That last step is required for realistic AI content.

TikTok's own help page shows the setting: tap More options, turn on AI-generated content, then post. TikTok has also labelled content automatically since May 2024 when the file carries Content Credentials metadata, as CNBC reported. Creators report that TikTok sometimes labels videos even when they did not disclose them, so trying to hide AI use is both against the rules and unreliable.

Post at a steady rhythm. One video a day is common advice, but three good ones a week beats seven rushed ones. If your goal is income, our guide on how people make money with AI videos on TikTok covers what each route pays and what it takes.

How long does your first week really take?

Plan for about 8 to 12 hours across your first week to get three videos posted. The first video eats half of that because steps 3 and 4 are new; the second and third reuse your setup.

The day 7 review is the part people skip. Your retention graph tells you which second lost viewers, which tells you exactly what to change in the next script.

What mistakes slow beginners down?

Most lost hours come from five habits, all of which show up repeatedly in Reddit threads.

1. Skipping the style lock. Every clip looks different, so you regenerate everything. Do step 3 first.
2. Long clips. A 10 second clip fails more often than two 5 second ones and costs more to retry.
3. Changing the whole prompt on a bad take. Change one thing per run so you learn what broke.
4. Copying other people's videos or face swapping creators. An r/artificial poster said face-swapped TikToks were flagged as not original. Make your own stories and characters.
5. Quitting at week three. The same thread noted most people drop off after two or three weeks without reach. Judge a format after 15 to 20 posts, not five.

A blunter r/aitubers reply pointed at the real gap in most tutorials: the workflow says "pick your topic, then generate images" and skips the part in the middle where the actual work happens. That middle part is steps 2 to 4 above.

Can you do it all for free?

Yes for a test, rarely for a daily habit. CapCut's Instant AI video turns a script into a video for free, and most generators have small free tiers; Fliki's free plan, for example, is 3 minutes of video a month at 720p with a watermark, according to its own page.

One r/aitubers reply argued the opposite extreme: run open models locally (style LoRAs and image to video models in ComfyUI) and pay nothing. That works if you have a strong GPU and time to learn it. For most beginners, the sensible order is free tools for the first five videos, then pay for one generator once you know the format is worth repeating.

Who is this not for?

This is not for anyone expecting money in the first month or a fully hands-off channel. AI tools speed up production; they do not replace choosing good stories, cutting carefully and posting consistently. Results vary widely, and many channels never find an audience.

Where to go from here

1. Pick one series format and write the payoff of your first story in one sentence.
2. Build your style line and character references once.
3. Make one 30 second video with the seven steps, timing yourself.
4. Post three videos this week with the AI label on.
5. Read the retention graphs and fix the second where viewers leave.
