Question 1

Faceless videos

Accepted Answer

A faceless video is a video you make without a camera or your face. You give AITuber a script or an idea. AITuber writes the voiceover with an AI voice, adds visuals, and adds captions that match each spoken word. This is the default video type in AITuber, and it works for Shorts, TikTok, Reels, and long YouTube videos.

What do I need?

A script, or just an idea. AITuber can write the script for you.
Credits. The cost depends on video length and the visual quality you pick.
A free account is enough for Moving AI Images, Stock Video, and Background Video. AI Video needs an active plan.
To download the video, your account must have had a paid plan at least once.

How do I create a faceless video?

Open the video creation page.
Type your idea, or paste your full script. You can add visual directions in [brackets], like [a storm over the ocean].

Pick a visual type: Moving AI Images, AI Video, Stock Video, or Background Video. AI Video shows a lock if you have no active plan.

For Background Video, select one clip or upload your own. For AI visuals, pick a quality tier. The credit cost per scene or per second shows next to each tier.
Pick a voice. You can preview each voice before you choose.
Pick an aspect ratio: 9:16 for Shorts, TikTok, a

Question 2

Manage or cancel your plan

Accepted Answer

You can cancel your plan yourself from the billing page, in a few clicks. You keep your credits and your downloads. Autopilot and publishing stop when the paid period ends.

How to cancel

Open the billing page.
Find your current plan card and click Cancel subscription.

Follow the short dialog and confirm with Cancel Subscription.

That is all. You will not be charged again.

When does the cancellation take effect

At the end of the billing period you already paid for. You keep full access until that date; the billing page shows it as Ends with the date.

What do I keep after I cancel

Your credits. All unused credits stay in your balance forever. They never expire, and you can still spend them to generate videos with AI images or stock footage.
Downloads. Downloading stays open. The rule is whether the account has ever had a plan, not whether one is active today. How to download your video.
Your videos. Everything you made stays in your account.

What stops when the plan ends

Autopilot. Autopilot needs an active plan. It keeps running until your paid period ends, then it stops.
Publishing and scheduling. Posting to your connected channels also needs an act

Question 3

AI video clips

Accepted Answer

AI Clips is a standalone clip generator. You write a prompt or upload an image, pick an AI video model, and get one raw video clip of 1 to 15 seconds. There is no narration and no captions; the clip itself is the product, ready to download or use anywhere.

What do I need?

A paid plan. Clip generation is paid-only from the first clip, because the output downloads directly.
A text prompt, an image, or both.
Credits. The cost is per second and depends on the model and resolution you pick.

How do I create an AI clip?

Open AI clips page.
Pick a mode: text to video, image to video, or first and last frame.

Pick a model. Each model card shows its cost per second and what it supports.

Type your prompt, or upload your image.
Pick aspect ratio, resolution, and duration. Higher resolutions cost more per second.
For models with sound, turn audio on or off. Audio raises the per-second cost.
Click Generate. Generation usually takes 1 to 3 minutes.

The finished clip appears in your clip list with a download button.

Which models can I pick?

Open the Model picker on the AI clips page to see the full list. We add new models often, so the picker is the only place that is always right.

Each model card shows what that model supports: its modes, aspe

Question 4

How long can my videos be?

Accepted Answer

You can generate AI videos up to 20 minutes long. That is the limit for faceless videos, the longest format. Other video types have shorter limits.

What is the limit for each video type?

| Video type | Maximum length | |---|---| | Faceless video (AI images, AI video, or stock) | 20 minutes | | Medical Animation | 20 minutes | | Skeleton video | 7 minutes | | 3D Talking Characters | 7 minutes | | AI Construction Timelapse | 1 minute | | Avatar video | 5 minutes | | AI Music Video | follows your song; uploaded songs up to 10 minutes | | AI video clips (clip generator) | 1 to 15 seconds per clip |

Script limits apply too: up to 30,000 characters and 400 scenes per video. The voice speaks about 3 words per second, so a 20-minute video needs about 3,600 words. Write your own script or let AI write it.

Why do some video types have shorter limits?

Two reasons:

Quality. Short formats like Skeleton and 3D Characters are built for short-form platforms. Long runs of AI video clips lose consistency, so we cap them where the result stays good.
Cost control. AI video costs credits per second. The caps stop one video from using far more credits than you expect. You always see the estimated credit cost before you generate.

Can I make a 20-minute AI video?

Yes. Use the faceless video type on the video creation page. Write or generate

Question 5

API quickstart

Accepted Answer

The AITuber API lets your code create, export, and publish videos. The base URL is https://app.aituber.app/api/v1. Full interactive docs with every endpoint live in the API documentation.

How do I authenticate?

Create a key on the API keys page and send it on every request:

Authorization: Bearer ak_your_key_here

Create and manage API keys.

The core loop: create, poll, export, download

1. Create a video. Send a topic (inputType: "idea") or your exact narration text (inputType: "script"):

curl -X POST "https://app.aituber.app/api/v1/videos/generate" \
  -H "Authorization: Bearer $AITUBER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "script": "5 facts about black holes", "inputType": "idea", "expectedDurationSeconds": 60 }'

The response contains a videoId. Generation spends credits, the same amounts as in the dashboard.

2. Poll until it is done. Call GET /videos/{id} every 30 seconds or so, until status is completed.

3. Export to MP4. Call POST /exports with the videoId. Export is free, but your workspace needs to have had a paid plan at least once. Rendering usually takes 30 seconds to 5 minutes.

4. Download. Poll GET /videos/{id} until exportStatus is completed, then call GET /exports/download?videoId={id}. The response contains a signed dow

Question 6

How credits work

Accepted Answer

Credits are what you spend to make a video on AITuber. You can see how many you have left on the credits counter in your dashboard.

This article explains how the credit system works. For the numbers, What each video type costs.

Where credits come from

There are four sources.

Signup bonus. You get 100 credits when you create your account. This is a one time bonus, not a monthly refill.
Free rewards for getting started. Before you buy anything, you can earn extra free credits by finishing the first steps: make your first video (25 credits), connect a channel (15 credits), and set up autopilot (25 credits). With the signup bonus, that is 165 free credits in total. Each reward is paid one time. The rewards checklist is on your dashboard, and it goes away after your first purchase.
A plan. Each plan adds credits every billing cycle: each month on monthly billing, or once up front for the year on yearly billing. A plan is also what unlocks downloads and AI Video.
A credit pack. A single payment that adds credits once, with no subscription. A pack does not unlock downloads.

For which to pick, Get more credits.

What uses credits

Every video charges for two things: the voice and the visuals.

The voice cost depends on how long the speech is. The visual cost depends on two choices you make:

**Which vi
