AI TikTok Video Generator: Settings, Costs and a Hook-Testing Workflow (2026)
Choose your settings and review the credit cost before generating.
Create your first videoThe useful thing an AI generator does for TikTok isn't one perfect video. It's letting you test several openings cheaply and keep the one viewers watch to the end. This guide covers the settings that matter for TikTok, what a test batch costs, and TikTok's own rules for AI content.
For planning a single clip and reviewing it before you publish, see How to Make AI TikTok Videos. This page is about the generator itself: models, settings and cost.
What TikTok says it rewards
TikTok says its For You feed weighs your interactions (likes, shares, follows, comments), video information (captions, sounds, hashtags) and device/account settings, and that "a strong indicator of interest, such as whether a user finishes watching a longer video from beginning to end, would receive greater weight than a weak indicator" (TikTok Newsroom, How TikTok recommends videos #ForYou).
Two practical consequences for AI clips:
- Short clips are easier to finish. Most models generate 4–15 seconds, which suits TikTok. Don't pad a 5-second idea to 15.
- The opening frame does the work. Generate the opening as its own shot and test versions of it, rather than regenerating the whole video.
Models that produce native 9:16 for TikTok
Every model below can output vertical 9:16 for text-to-video. For image-to-video, the output follows your photo's shape, so crop it to 9:16 first.
| Model | Durations | Cheapest vertical clip | Audio | Use it for |
|---|---|---|---|---|
| Vidu Q3 Turbo | 5, 8, 10, 16s | 2 credits (540p, 5s) | Yes | Many cheap concept tests |
| Grok Imagine | 5, 6, 10, 15s | 2 credits (480p, 5s) | No toggle | Fast rough ideas |
| VEO 3.1 Lite | 4, 6, 8s | 3 credits (720p, 4s) | Yes | Cheap tests with sound |
| Hailuo 2.3 | 6, 10s | 4 credits (720p, 6s) | — | Physics, anime, satisfying loops |
| VEO 3.1 Fast | 4, 6, 8s | 6 credits (720p, 4s) | Yes | Clean final version |
| Kling 3.0 Standard | 5, 10, 15s | 8 credits (1080p, 5s) | Yes | 1080p final with motion |
| Seedance 2.0 | 5, 10, 15s | 10 credits (480p, 5s) | Yes, lip sync | Someone talking to camera |
Credits cost $0.30 each on the $9 Mini pack and about $0.18 on the $299 Business pack. All prices are from the live catalog (September 2026); the create page shows the exact cost before you generate.
Workflow: test five hooks for about $5
- Write one core idea, such as "a messy desk transforms into a clean setup."
- Write five opening variations: a result-first shot, a close-up detail, a before state, a surprising angle and a text-free reaction. The create page's Hooks button (1 credit) suggests opening lines if you're stuck.
- Generate each as a 4-second VEO 3.1 Lite clip at 720p, 9:16: 5 × 3 = 15 credits ($4.50 on Mini, $2.72 on Business).
- Pick the two strongest, then regenerate them at the length and quality you'll post, for example VEO 3.1 Fast at 8 seconds (12 credits each at 720p).
- Post both on different days and compare average watch time and completion in TikTok analytics, not just views.
No prompt? Start from a one-photo template
If you don't have an idea yet, the template gallery turns one uploaded photo into a trend-format clip with a tuned prompt and default settings, for example Paparazzi Flash, Earth Zoom or Anime Portal, and for pets Pet Superstar. Each template page shows the model, duration and credit cost before you start, and you can swap the model if you want a different look. A template is a format to test, not a guarantee of views.
For product ads, the UGC studio does steps 2–3 for you (overview on the UGC ads page): pick a format (testimonial, unboxing, demo, before/after, problem → solution, GRWM, tutorial, comparison, lifestyle or faceless hands-only), choose Seedance 2.0, VEO 3.1 Fast or Kling 3.0 Pro, and generate 1–3 variations at once. Each variation is charged as a separate clip.
Sound: generate it or add it in TikTok?
- Native audio (VEO, Kling 3.0, Seedance, Vidu Q3 Turbo) gives you ambient sound or speech that matches the video. Good for talking or ASMR-style clips.
- A TikTok sound is added in the TikTok app after upload. If you plan to use one, turn audio off when generating so the two don't clash.
- Your own narration: generate a voiceover (1 credit per 500 characters of script, minimum 2) and lay it under the clip in your video editor.
Captions and on-screen text
- The caption generator writes a short post caption (about 150 characters) with 6–9 hashtags from your prompt. Free.
- Auto Subtitles burns animated word-by-word captions into a clip that has speech. 3 credits, clips up to 5 minutes, 8 languages.
- Don't ask a video model to write long on-screen text. It often misspells it. Add text overlays in TikTok's editor instead.
TikTok's rules for AI-generated content
TikTok requires creators to label AI-generated content that shows realistic scenes or people, and it may remove unlabeled realistic AIGC (TikTok Support: AI-generated content). Turn on the AI-generated content setting when you post a realistic clip. Clearly stylized content like anime or 3D cartoons is lower risk, but labeling costs you nothing.
Also:
- Don't generate a real, identifiable person. Viralance blocks prompts that depict named public figures.
- Don't present an AI "customer" as a real testimonial. Say it's a dramatization, or use real reviews.
When an AI generator is the wrong tool for TikTok
- You're the brand. Personal-creator accounts grow on a recognizable face and voice; AI clips work better as b-roll than as a replacement.
- Trend formats that depend on a real moment (reactions, live events, duets) don't translate well.
- Long explainers. One generated clip tops out at 8–15 seconds on most models (Seedance 2.5 reaches 30). For a 60-second story, use the Film tool to stitch 4–12 shots, or edit clips together yourself.
Frequently asked questions
Does Viralance post to TikTok for me? No. Download the MP4 and upload it in the TikTok app, where you add sounds, text and the AI label.
What's the cheapest way to test TikTok ideas? A 5-second Vidu Q3 Turbo 540p or Grok Imagine 480p clip costs 2 credits ($0.60 on Mini). The 4 free credits on a new verified account cover two such tests.
Can I make TikToks without showing my face? Yes. See the faceless video guide for formats and costs.
Do I own the videos? Viralance's terms state you keep ownership of what you generate. You're responsible for the rights to anything you upload and for following TikTok's rules.
