Hedra

What it is for

Hedra is a hosted character video studio plus a v3 API: the public Character-3 developer canvas (see the cover) is Start frame, Audio, speaker positions, a prompt, 720p output, and a live curl panel. Use it when the job is turn a still + audio into a talking or singing clip.

Hosted product with a prepaid API wallet. Studio credits sit on a separate tab.

What makes it unique: the cover is the live Character-3 form (image + required audio + resolution), the same surface the REST job uses.

Key features

• Character-3 composer — start frame, audio (0.5–600s), speaker points, prompt, 720p (cover).
• Longform avatar — official copy: talking and singing clips with speaker selection up to 10 minutes.
• Resolutions — 540p / 720p / 1080p on the model page (1080p printed 6.25¢/second).
• v3 prepaid wallet — fund dollars, estimate, then submit (docs Quickstart).
• Studio tab — subscription credits are a second meter on hedra.com/pricing.

Who it's for

Best fit: creators and developers who already have a face still and a voice track and will pay per second.

Pricing

Verified 2026-10-22 (Asia/Shanghai) from the live hedra.com/pricing API tab (JS-rendered cents) and the Character-3 model page. Re-check the Studio toggle before you buy a seat.

API (prepaid USD wallet, no seat on this tab):

• Video generation — from 1.13¢ / second.
• Avatar & lip-sync — from 2.5¢ / second.
• Character-3 1080p — 6.25¢ / second on the model page.
• Image generation — from 0.59¢ / generation.
• LLM / VLM — from $0.15 / $0.50 per 1M in/out on the same API table.

Studio subscription cards sit behind the Studio toggle. The API tab prints per-output cents only.

Limitations / costs

• Audio is required on Character-3 (0.5–600 seconds).
• Studio credits and the v3 wallet are separate. An unfunded wallet blocks API jobs.
• Seconds are the meter. A 10-minute 1080p clip burns at the 6.25¢ rate.
• The consumer app is sign-in. The cover is the public developer canvas.

Alternatives

• HeyGen — script-to-avatar studio with Creator / Pro cards when you want a presenter from text.
• Kling AI — cinematic text-to-video composer when the job is a scene from a sentence.
• Runway — signed-out video/image composer with yearly Standard / Pro / Max cards.
