# Generate avatar clip

`POST /v1/tools/generate-avatar`

Generate a talking-head avatar video by pairing an ACTOR entity with an audio file, typically from a prior text-to-speech result.

## Request body

- GenerateAvatarRequest — Generate a talking-head avatar from an ACTOR entity and audio.
  - `actorEntityId` string, required — The id of a built-in stock actor or an ACTOR entity (e.g. `vg_enti_...`) with an image reference.
  - `avatarQuality` 'LOW' | 'STANDARD' | 'HIGH' | 'MAX' — AI generation quality tier, shared across every generative feature (image, video, text, and so on). `LOW` is fastest and cheapest, `STANDARD` balances quality and cost, `HIGH` is higher quality, and `MAX` is the highest quality. When a request omits the quality field, VideoGen falls back to your account's **Default AI quality** for that feature, which you can change at [Account settings](https://app.videogen.io/settings/account). Not every feature supports every tier; unsupported tiers are rejected with an error (see each field's description).
  - `audioFileId` string, required — File id of an AUDIO file (e.g. `vg_file_...`), typically from a prior text-to-speech result. Upload a file first via `POST /v1/files/upload` or generate one with `POST /v1/tools/text-to-speech`, then pass the returned id here.
  - `watermarkMode` 'NONE' | 'VIDEO_GEN' | 'AUTO' — Controls whether the VideoGen watermark is applied to the output. `AUTO` applies the watermark unless you have a Pro plan. `VIDEO_GEN` always applies it. `NONE` removes the watermark (requires Pro; returns an error if you don't have it).
  - `numResults` integer — Number of output results to generate. Defaults to 1.
  - `isOutputTemporary` boolean — When true, generated files are temporary. Temporary files are guaranteed to be available for 24 hours, after which they may be archived at any time. Temporary files are not analyzed (no description, transcript, or embedding will be generated), so they will not appear in search results. Defaults to false.
  - `hideFromUi` boolean — When true, generated files are hidden from the VideoGen Media page by default. They remain accessible through the API. Defaults to false.

## Response `202`

Execution accepted; poll until complete.

- StartToolExecutionResponse — Returned when a tool execution is started. Use `toolExecutionId` to poll for results or cancel.
  - `toolExecutionId` string, required — Execution id (e.g. `vg_tool_...`).

## Other responses

- `default` — Error
