AI character and video studio
How to use
Hedra.
Producing short speaking-character clips, audio-driven avatars, stylized character performances, and assembled multi-scene videos from controlled image and voice assets.
Hedra is a AI media platform for character, avatar, image, video, voice, and multi-scene creation. Producing short speaking-character clips, audio-driven avatars, stylized character performances, and assembled multi-scene videos from controlled image and voice assets. This guide covers the whole path in one place: official access, a first session that produces something reviewable, the checks that make output trustworthy, and the permissions worth limiting before you connect real work.
AI should make the work easier to inspect. If the workflow removes the source, the owner, or the review step, redesign the workflow.

First session
Your first useful Hedra session
Learn the interaction loop using a small task with a clear outcome.
- 01
Define the audience, script, character, voice, disclosure, distribution rights, and success criteria before uploading any identity material.
- 02
Use only an owned or expressly authorized image and audio recording, documenting consent for synthetic performance and biometric processing.
- 03
Create a short low-resolution test with clean audio and a front-facing image before spending credits on longer or higher-resolution output.
- 04
Review lip-sync, identity, gestures, speech, captions, artifacts, disclosure, and audience permissions before exporting or sharing.
- State the outcome before the background.
- Provide the real source material.
- Review the result before expanding the task.
Quality control
Check the quality of Hedra output
Turn a promising generation into an asset you can legally and safely ship.
- 01
Restate the brief, the deliverable format, and where the asset will appear before judging any output.
- 02
Inspect at full resolution: generated media hides its errors at thumbnail size.
- 03
Check the details these systems reliably get wrong — hands, text, logos, reflections, symmetry, and edge artefacts.
- 04
Confirm the licence and commercial-use terms for your plan, and check the output does not reproduce a recognisable style, mark, or likeness you have no right to use.
- 05
Review for accessibility and delivery: alt text, contrast, colour profile, file size, and the exact export format.
- Inspect at full resolution before approving anything.
- Confirm commercial-use rights before an asset reaches a client.
- Keep the prompt and settings with the asset so it can be reproduced.
Privacy & permissions
Use Hedra safely
Use the platform without surrendering rights, likenesses, or client material you do not control.
- 01
Confirm you hold the rights to every reference image, voice, or clip before uploading it.
- 02
Check whether your plan trains on submitted content, and opt out before uploading client work.
- 03
Never upload a real person's likeness or voice without their explicit, documented consent.
- 04
Review the output for marks, styles, or likenesses you have no licence to reproduce.
- 05
Label synthetic media where your client, platform, or jurisdiction requires disclosure.
- Avatar and voice workflows may derive biometric information from faces and audio. Hedra's terms give it a broad license to user content for operating the service, subject to settings and agreements. Never animate or clone a real person without specific consent, upload confidential recordings casually, or imply authentic speech or events. Review current terms, privacy and biometric policies, model providers, library visibility, deletion, rights, and synthetic-media disclosure before publication.
- Follow your organisation's approved-use policy.
- Never treat fluent output as authorization to act.
Core workflows
Step-by-step ways to use Hedra for the work it does best.
Each workflow below has its own outcome, steps and review checkpoints.
Turn an authorized image and voice into a polished short avatar clip with explicit identity, disclosure, and quality controls.
↓ 02 WorkflowAssemble a multi-scene character video with Hedra ComposerPlan and combine short generated scenes so continuity, pacing, audio, cost, and approvals remain manageable.
↓Workflow 01
Create a consented speaking-character video in Hedra
Turn an authorized image and voice into a polished short avatar clip with explicit identity, disclosure, and quality controls.
Outcome: Publish a clear synthetic performance without misrepresenting a real person or losing control of their likeness and voice.
- 01
Document the speaker or rights holder's consent, allowed script, channels, duration, audience, territories, revocation path, and synthetic-media disclosure.
- 02
Prepare a front-facing authorized image and clean authorized audio, removing metadata and private background details that are not needed.
- 03
Generate a short low-resolution test with the chosen avatar model, aspect ratio, neutral motion prompt, and no public sharing.
- 04
Review pronunciation, lip-sync, identity, gaze, teeth, hands, gesture, emotion, captions, background, and whether the performance implies unapproved claims.
- 05
Correct the source or prompt, render only the approved take, add visible disclosure and accessibility, obtain final sign-off, and delete unused identity assets where appropriate.
What good use looks like
- Get specific written consent.
- Test with a short clip first.
- Keep disclosure attached to the media.
Workflow 02
Assemble a multi-scene character video with Hedra Composer
Plan and combine short generated scenes so continuity, pacing, audio, cost, and approvals remain manageable.
Outcome: Produce a coherent multi-scene draft that can survive editorial, identity, and rights review.
- 01
Break the script into a shot list with purpose, duration, character, line, framing, motion, transition, asset rights, and per-scene approval criteria.
- 02
Create locked character and voice references, a continuity sheet, captions, pronunciation notes, credit budget, and clear filenames before generation.
- 03
Generate one short scene at a time, starting with the highest-risk identity and motion shots and avoiding long expensive renders until the look is approved.
- 04
Review each scene for continuity, identity drift, lip-sync, emotion, timing, background, audio level, artifacts, and unwanted content before adding it to Composer.
- 05
Assemble and trim the sequence, perform a full rights, disclosure, accessibility, music, factual, and stakeholder review, then export a versioned final with source records.
What good use looks like
- Lock continuity references early.
- Approve scenes before assembly.
- Keep a versioned source record.
