Open **Avatars** in the sidebar. The **Studio** tab builds a new avatar video; the **Library** tab keeps your avatars and the videos you've made. ![The Avatar Studio with the avatar picker, the script editor and the preview](https://mintcdn.com/crealix/_9Ls_G9_DBUcpK_e/images/app/v2/tl-avatars.jpg?fit=max\&auto=format\&n=_9Ls_G9_DBUcpK_e\&q=85\&s=92eb2854c93fa24bccbdb1fd8e234d22) ① Library / Studio · ② Choose avatar, Upload photo or Create new · ③ Write script or Upload audio · ④ Preview / Examples · ⑤ Language, voice and music · ⑥ Generate video ## 1. Choose your avatar Three ways to get a face (②): * **Choose avatar** — pick one of the curated faces, ready to use. * **Upload photo** — use your own photo. A front-facing, well-lit portrait from the shoulders up works best, with a plain background and nothing covering the face. Only upload people who agreed to it. * **Create new** — describe a character and AI generates a brand-new face: a presenter, a mascot or a stylised character. ## 2. Write the script Choose how the avatar gets its voice (③): * **Write script** — type what the avatar should say, up to 5,000 characters, and choose the **Narration Language** (English, Spanish, Portuguese, French, German, Italian, Chinese, Japanese and more under **See more**). * **Upload audio** — use your own voice track. The avatar lip-syncs to it, so you don't need a voice. > [!TIP] > > Write the way people talk: short sentences, one idea each. Punctuation drives the pauses — a comma is a short breath, a full stop a longer one. Read it out loud once before generating. ## 3. Pick a model and a format ![The Pick a model step with HeyGen Avatar 4 selected and the aspect ratio options](https://mintcdn.com/crealix/_9Ls_G9_DBUcpK_e/images/app/v2/tl-avatars-model.jpg?fit=max\&auto=format\&n=_9Ls_G9_DBUcpK_e\&q=85\&s=61da60867dffc8ac80e890202af2a000) ① Change model · ② The selected model, its tier and price per second · ③ Quality, realism and speed · ④ Aspect ratio **HeyGen Avatar 4** is selected and recommended. Click **Change** (①) to compare the four models side by side: ![The model picker with HeyGen Avatar 4, OmniHuman, Kling AI Avatar v2 Standard and Pro](https://mintcdn.com/crealix/_9Ls_G9_DBUcpK_e/images/app/v2/tl-avatars-models.jpg?fit=max\&auto=format\&n=_9Ls_G9_DBUcpK_e\&q=85\&s=198afe72648226ba893237c451d1ba74) ① What the model lets you control · ② Tier · ③ Price per second of video | Model | Tier | Price | Best for | | - | - | - | - | | **HeyGen Avatar 4** (recommended) | Premium | 5 credits/s | The most lifelike faces, with talking style, expression and HD options — up to 1080p | | **OmniHuman** | Standard | 8 credits/s | Full-body presenters with gestures inferred from the voice. Up to 30 seconds | | **Kling AI Avatar v2 Standard** | Budget | 3 credits/s | The cheapest option — realistic humans, cartoons or stylised characters, with optional style direction | | **Kling AI Avatar v2 Pro** | Premium | 6 credits/s | Sharper rendering and smoother motion than Standard | The cost is the length of the video times the price per second — a 30-second video with HeyGen Avatar 4 costs about 150 credits. The exact total is always shown at the bottom before you generate. Then pick the **Aspect Ratio** (④): **9:16** Portrait for TikTok, Reels and Shorts, **16:9** Landscape for YouTube and webinars, or **1:1** Square for Instagram feeds. ## 4. Voice, music and captions Further down the Studio: * **Voiceover** — over 1,800 voices, with featured ones on top; **Browse all** opens the full library. Your [cloned voices](https://docs.crealix.ai/workspace/my-voices.md) are here too. (Not needed if you chose **Upload audio**.) * **Background Music** — the Crealix library, **My Music** (tracks you made in [AI Music](https://docs.crealix.ai/tools/ai-music.md)) or **Custom** uploads. Planning to publish on YouTube? Some library tracks may cause copyright claims; your own uploads or music made in Crealix are the safer choice. * **Caption Style** — 48 presets in the Crealix Library, plus your own styles under **My Captions**. ## 5. Performance controls Open **Performance controls** at the bottom of the Studio to direct the delivery. ![Performance controls: quality profile, performance intensity and facial expression](https://mintcdn.com/crealix/_9Ls_G9_DBUcpK_e/images/app/v2/tl-avatars-performance.jpg?fit=max\&auto=format\&n=_9Ls_G9_DBUcpK_e\&q=85\&s=db5e4a5636900bf6cd74c0d4739a9076) ① Quality profile · ② Performance intensity · ③ Facial expression * **Quality profile** (①) — **360p** Fast draft, **480p** Standard, **540p** HD, **720p** Creator quality (default) or **1080p** Cinematic. Test a script at a low resolution, then make the final at 720p or 1080p. * **Performance intensity** (②) — **Natural & composed** for a calm presenter, or **Animated & expressive** for more energy and movement. * **Facial expression** (③) — for example **Happy expression** for a friendlier delivery. The controls depend on the model — these are HeyGen Avatar 4's. The Kling models show **Style direction** instead. ## 6. Preview and generate **Preview** (④) shows your avatar in the chosen format; **Examples** plays sample videos. Below it you see a summary of the language, voice and music (⑤). Click **Generate video** (⑥) — **credits are only charged when generation starts**, and failed generations are refunded. Finished videos appear in the **Library** tab and in your media library. ## Use avatars in other videos Avatar videos are saved to your media library. You can: * Place one as a **video overlay** on top of any Crealix video — like a presenter in the corner. See [Text overlays & your logo](https://docs.crealix.ai/editor/text-and-logo.md#video-overlays). * Use one as a source in a [Split Video](https://docs.crealix.ai/formats/split-videos.md) — for example a presenter on top and gameplay below. * [Upscale](https://docs.crealix.ai/tools/upscaler.md) it to 2K or 4K.
