Hedra

Hedra (/media/hedra) generates expressive character videos from a single portrait keyframe and a text prompt, powered by Hedra's Character-3 model.

Where to configure

Configure a Hedra API key under Settings → Media → Hedra. This is an own-key provider and does not reuse an AI key. See Settings for credential setup.

Generation flow

Jobs follow the standard Media Studios flow: submit the form, track progress in the Render Queue, and the finished video lands in /files. From there you can open it in the Designer or post it.

Caveats

• Portrait is required. The source image (start_keyframe) is resolved server-side to a provider-reachable URL before generation starts.
• Asynchronous. Completion is delivered by webhook when available; the media-jobs-poll cron acts as a fallback.
• Only one tab/operation is exposed: character video from a keyframe.
