Hedra Character 3

Hedra Character 3 is an omnimodal model designed specifically for image-to-video lip-syncing. It turns a single static portrait and an audio file into a talking avatar. The community notes its ability to generate natural micro-expressions—like blinks, eye shifts, and subtle head tilts—that sync accurately with speech phonemes. This makes it useful for character-driven storytelling, virtual presenters, and social media content, avoiding the stiff movements common in older avatar tools.

Released in March 2025, Character 3 succeeded Hedra Character 2 by introducing simultaneous processing of image, text, and audio for improved facial animation. Within the family, it remains the go-to option for locked-camera talking avatars generated from a single image and an audio track.

Because the model uses audio as the core driver for facial animation, your audio quality heavily dictates the output. Use clean speech with clear pronunciation and zero background noise or heavy reverb. If you notice the character making overly dramatic or unnatural hand gestures—a common quirk noted by users—use your text prompt to explicitly restrain their movement. For more detailed workflows, check out external prompt guides. Additionally, generating a library of approved character angles helps maintain consistency across videos.
