Ayarlar

Avataristeğe bağlı

Name of the Avatar V-eligible avatar to use.

Voiceisteğe bağlı

Name of the text-to-speech voice to use for the avatar when ``audio_url`` is not provided.

Audio Urlisteğe bağlı

HTTP(S) URL of an audio file for the avatar to lip-sync to. When provided, the avatar uses this audio instead of text-to-speech and ``prompt``/``voice`` are ignored.

Fitisteğe bağlı

How the avatar fits within the output frame. 'contain' keeps the full avatar in view (may letterbox); 'cover' fills the frame (may crop).

Remove Backgroundisteğe bağlı

Remove the avatar's background. Requires a matting-enabled avatar.

Backgroundisteğe bağlı

Optional background to composite behind the avatar. Ignored when ``output_format='webm'`` (webm output is transparent).

Watermarkisteğe bağlı

Optional watermark image to overlay on the output video.

Captionisteğe bağlı

Generate a sidecar SRT caption file alongside the video.

Output Formatisteğe bağlı

Output container format. 'webm' produces a transparent video (automatically removes the background) and ignores the ``background`` field.

Resolutionisteğe bağlı

Output resolution preset.

Aspect Ratioisteğe bağlı

Aspect ratio of the output video. Supported values: '16:9', '9:16', '4:5', '5:4', '1:1', and 'auto'. 'auto' preserves the source aspect ratio when HeyGen can read it, falling back to '16:9' otherwise.

Enable Safety Checkeristeğe bağlı

Authorized callers may set false to request relaxed screening.
