How do I make AI influencer videos?
Start from one fixed image of your character, paint an opening frame for the scene, then animate it with a video model using a timed prompt that quotes every line of dialogue. Models with native audio render the voice and lip-sync in the same pass; if you want the character to speak your own recorded audio, use a talking-avatar tool instead.
The workflow we use
- Opening frame. Generate a still of the character already in the scene, framed the way the video should start. The image prompt carries the look; the video prompt only has to carry motion and sound.
- Timed prompt. Write the clip as beats:
0-4s,4-9sand so on, one action and one quoted line per beat. In our renders Seedance followed timestamps far better than a paragraph of prose. - Camera line. Say where the camera physically is: "the phone propped on the table, eye level, the only viewpoint, no cuts". This stops the model inventing cuts.
- Avoid list. No subtitles, no on-screen interface, no phone in frame, no change to her face.
- One take. Render once. If it is wrong, change the prompt and re-render that take rather than batching spares.
The full structure, with a copyable skeleton, is in our Seedance prompting field guide. If you would rather not write prompts by hand, the free video prompt builder assembles one from a few picks.
How to make the influencer talk
There are two routes, and they suit different videos.
| Route | How it works | Good for |
|---|---|---|
| Native audio in the video model | Put the line in quotes in the prompt; the model generates voice, lip movement and room sound together. Kling says its models generate dialogue with lip sync[1]. | Acted scenes, livestream clips, dances with a spoken line |
| Talking-avatar tool | You supply an image and speech audio. Kling Avatar 2.0 takes an avatar image, speech audio and an optional prompt[2]; Hedra describes Character 3 as audio-to-video up to 10 minutes[3]. | Scripted talking heads, long explainers, a voice you recorded |
In our Seedance 2.5 renders, quoted lines came out lip-synced in the voice we described in words ("posh English drawl"). Describe the voice in every prompt or it changes between videos.
Formats that work
- Phone-POV livestream: the character films herself and talks to her chat. Example: hate mail.
- Borrowed creator format: a beauty tutorial, a room tour, a get-ready-with-me. Example: love potion tutorial.
- Dance to a song: pass the song as an audio reference so moves land on the beat. Example: look up.
- Explainer: many short clips of one character cut to a voice-over. Example: Penny.
How long should they be?
Our influencer clips run 15 to 30 seconds: long enough for a setup and a turn, short enough to rewatch. Thirty seconds holds about five beats; 15 seconds holds two or three. If you want TikTok Creator Rewards income, note that videos must be at least one minute long to earn under that program[4], so a monetized account needs longer cuts made from several clips.
Where Cast fits
- You want the workflow above done from one line: Cast keeps the character's reference image, has a language model expand your line into a shot-by-shot prompt and renders on Seedance 2.0 Fast at 720p.
- You want the livestream look: the Selfie / Live camera adds the one-take phone-POV instruction for you.
- You want up to 3 characters in one video, for example a group dance or a friend photobombing.
Where it does not:
- Lip-sync to audio you recorded: Cast generates the voice from the prompt.
- One continuous take longer than 15 seconds.
- An avatar of yourself or another real person.
People also ask
- What tools make AI influencer videos?
- Two kinds: video models with native audio, such as Seedance, Kling[1] and Veo[7], for acted scenes, and talking-avatar tools such as HeyGen[8] and Hedra[3] for scripted talking heads. Our best AI influencer video generator page compares them.
- Can I make AI influencer videos on my phone?
- Yes. Browser-based tools work on a phone; you do not need editing software for single clips. Joining several clips into a longer video needs an editor.
- Why does my influencer's face change between videos?
- Usually because each video starts from text instead of the same image. Start every video from the master image and repeat the full description; see character consistency.
