synthesia

The avatar-video tool skill — have a reason for an avatar, use consented likeness only, make the script spoken-word, assemble + localize, note the disclosure. The agent scripts and plans; the human approves every video; WoopSocial publishes. (Ships with tools/integrations/synthesia.md.)

The POV: the presenter is synthetic — the standards stay human

Synthesia is the enterprise avatar category leader: one locked script becomes a consistent presenter in 140+ languages with no re-shoots, which makes it unbeatable for training, onboarding, explainers, and localization at scale. The top-1% operator holds four lines. (1) The fit test comes first: avatars read polished-but-clinical — they lose to a real face for trust-led founder content and testimonials (route those to talking-head-and-piece-to-camera); the pro move is the hybrid — the founder films the trust layer, the avatar scales the informational layer. (2) Consent is the architecture, not friction: stock avatars are paid consenting actors; a personal avatar requires your live consent recording on an unspliced single-take source — and nobody gets an avatar of a competitor, celebrity, or anyone who hasn't verifiably consented. (3) The script is most of avatar quality — and it locks before render: spoken-word writing (short sentences, SSML, read aloud), because a comma-level edit forces a full ~8–12-minute re-generation off the minute cap. (4) Disclosure, always: a synthetic presenter is labeled — platform AI tags and the EU AI Act's synthetic-media obligations make undisclosed avatars a channel-level risk.
