Bridge start and end stills into smooth cinematic video
A portrait shows a face. The line you type has to become a performance. Avatar V times the mouth to that script and adds a small nod or a quieter hand when you ask.
| Advantage | What you get |
|---|---|
| Script-led speech | The mouth follows the words you submit. |
| A reusable look | One public person can carry a whole series of Avatar V clips. |
| Optional motion | A short note can request a nod. Skip it and the Avatar V line still leads. |
| One rate | 720p and 1080p share the same price per second. |
You pick a voice on this page. You do not upload a recording. Camera directions will not rebuild the Avatar V room, because the look already has its set.
On RunComfy, try a line in the model UI, then repeat the same look, voice, and script through the HTTP API.

Avatar V turns a written script and a public look into a lip-synced talking clip. The mouth follows the words you submit, and an optional motion note can ask for a nod or a quieter hand. It fits product hosts, lesson intros, and short founder updates.
Avatar V offers eight public looks, each with a paired voice, plus eight named public voices. Choose Match look to keep the voice that belongs to the selected person, or pick a named voice when you want a different read. You do not upload a recording on this page.
Avatar V accepts a script of up to 5000 characters, and the spoken line sets the length. There is no duration slider. A longer script costs more only because the finished video is longer.
No. Avatar V bills $0.11 per second of the finished clip at both 720p and 1080p. The look and the voice do not add a separate fee. Read the line once if you want a rough length before you generate.
Use the Avatar V motion note for one small gesture, such as a nod or an open hand. Opposite moods in the same note fight each other. Leave it empty when you only want the words spoken.
Avatar V needs a public look, a voice, and a script. Resolution is 720p or 1080p. The motion note is optional, and the script must stay within 5000 characters. These looks are not a title tool, so add captions afterward.
Yes. Prototype Avatar V in the Playground Web UI, then send the same look, voice, script, resolution, and optional motion note through the RunComfy API. The API uses the same model. It does not promise a fixed turnaround or unlimited concurrency.
