What the tool does

LipSync animates a single photo to talk, using your audio and an optional text prompt — powered by OmniHuman 1.5. Your character's lips move naturally in sync with the audio, facial expressions match the emotion and context, and identity (face, style, hair, lighting) stays consistent throughout. Works even with very short audio clips. Fully uncensored.

Your step-by-step guide

Step 1. Model — LipSync currently runs on a single model, General, powered by OmniHuman 1.5: unrestricted character behavior, realistic micro-expressions, understanding of audio meaning (not just sounds), smooth head motion and natural gestures, and strong identity preservation.

Step 2. Image — required. Upload the face or character you want to animate. JPG, PNG, JFIF, or HEIC, under 5MB, up to 4096×4096. Best results come from a frontal or ¾ angle, high resolution, clear lighting (no heavy shadows), no obstructions on the face, and one person in the image.

Step 3. Audio File — required. MP3 or WAV. The tool reads speech semantics, not just phonemes — it understands what's being said and creates matching reactions and expressions. Clean voice recordings work best; avoid background noise or music, and keep the volume normal (not overly compressed).

Step 4. Prompt (optional) — describe what you want in the video: emotion, tone, style, camera movement, character behavior, or scene atmosphere. Example: "Confident, soft smile, warm emotional tone. Slight head tilt. Friendly and inviting mood."

Step 5. Resolution — locked at 1080p for this model.

Step 6. Duration — determined automatically by the length of your uploaded audio file.

Step 7. Generate Lipsync — starts the run. Costs 3 credits per second of audio. Processing usually takes 5–30 seconds depending on video length.

Pro tips

Choose the right reference image: avoid cropped faces, heavy filters, sunglasses, or large masks — use sharp, high-quality portraits.

Record clean audio: speak clearly, avoid echo and background effects, and keep mouth movements natural.

Prompt effectively: prompts help but shouldn't contradict the audio. Good: "Soft, emotional delivery. Gentle eye movement." or "Energetic influencer style, smiling while speaking." Avoid: "Screaming and jumping" over calm audio, extremely complex camera moves, or physical actions that aren't possible in a portrait frame.

For AI models / virtual influencers: when generating multiple videos of one character, reuse the same set of reference photos and keep the photo style and lighting consistent across shoots.

Troubleshooting

You're working with AI — occasional mistakes or artifacts are normal, and a 100% correct result isn't guaranteed.

Mouth desync or unnatural lips? Check audio clarity, avoid noise-suppressed/robotic recordings, and shorten audio to remove long silent gaps.

Face distortion or identity drift? Use a higher-quality reference image, avoid extreme camera angles, use portrait orientation, and avoid low-light, grainy photos.

Emotion not matching? Adjust the prompt, avoid conflicting instructions, and make sure the audio itself has clear emotion.
