AI TikTok video generator: from idea to upload-ready TikTok

TikTok rewards videos that grab attention immediately and keep it. That means a fast hook, frequent visual changes, captions people can read in a glance and a reason to watch until the end.

ShortsMachine creates TikToks end to end: a punchy script, a new AI-generated shot for every beat, narration, captions and a single vertical MP4 you can upload straight away.

TikTok formats that work well with AI

Storytime: a short narrative with a twist, told over cinematic scenes.
Did-you-know: three to five surprising facts with a strong visual for each.
POV and "what if": imaginative scenarios that AI visuals handle well.
Explainers: one concept explained simply in under a minute.
Product teasers for small brands.

Tips for TikTok

Keep most TikToks between 20 and 60 seconds; go longer only for stories.
Use a voice and style consistently so your account is recognisable.
Post in series ("Part 1, Part 2") to bring viewers back.
Write a caption and hashtags on TikTok itself — the video already has burned-in captions.

A simple TikTok structure

Second 0–2: the hook — a bold claim, question or striking image.
Seconds 3–40: the payoff, one beat per scene, changing visuals every few seconds.
Final seconds: a twist, a question for the comments, or a tease for part 2.

Picking a model for TikTok

For daily posting, Wan 2.2 Fast and HeyGen Video 1 keep costs at about one credit per second; HeyGen also adds ambient sound. For videos that need to stop the scroll visually, Grok Imagine and FLUX 3 Max give cleaner motion at a moderate price, and Kling 3.0 or Seedance 2.0 Mini on Premium give the most cinematic results.

Frequently asked questions

Will my TikToks have a watermark?

No. Videos made on paid plans have no ShortsMachine watermark.

Can I add trending sounds?

Trending sounds are added inside the TikTok app. ShortsMachine videos include narration and, on some models, ambient sound, which you can keep or lower in TikTok’s editor.

Can I make TikTok series?

Yes. Keep the same art style, voice and character description across prompts and label them Part 1, Part 2 and so on.

What size are the videos?

Vertical videos export at 720×1280 at 30 fps, which TikTok accepts.
