Lip Sync is a powerful tool based on OmniHuman 1.5 (uncensored) that allows you to animate any character’s face using your audio + optional text prompt + a single reference image.
It creates high-quality talking videos where the model accurately understands speech, emotion, timing, and context.
What the Lip Sync Tool Does
Lip Sync generates a video where your character:
moves lips naturally and precisely according to the audio
performs facial expressions that match emotion and context
keeps full identity consistency (face, style, hair, lighting)
can move slightly (head, eyes, micro-gestures)
can follow actions inferred from the audio meaning
uses camera motion and character motion enabled by OmniHuman 1.5
The tool works even with very short audio segments and maintains high realism without censorship restrictions.
Inputs
The Lip Sync tool uses three types of input:
1. Reference Image (required)
This is the face or character you want to animate.
Recommendations:
frontal or ¾ angle
high resolution
clear lighting (no heavy shadows)
no obstructions on the face
one person in the image
2. Audio File (required)
The tool reads speech semantics — not only phonemes.
This means the model understands what is being said and creates corresponding reactions and expressions.
Supported formats:
.mp3,.wav,.m4a
Tips:
Clean voice recordings perform best
Avoid background noise or music
Normal volume (not overly compressed)
3. Text Prompt (optional)
You can provide additional instructions to guide:
emotion
tone
style
camera movement
character behavior
scene or atmosphere
Example:
“Confident, soft smile, warm emotional tone. Slight head tilt. Friendly and inviting mood.”
Output
You receive a high-quality talking-head video of your selected character based on:
the reference image identity
the audio’s timing, semantics, and emotions
the optional prompt guidance
Video quality depends on your subscription tier.
📌 How to Use Lip Sync (Step by Step)
Upload your character photo
Make sure the image is clean, well-lit, and shows the face clearly.Upload your audio file
Drag-and-drop or select from your device.(Optional) Add a text prompt
Use this to adjust emotion, performance, camera movement, personality, or mood.Click Generate
Processing usually takes 5–30 seconds, depending on video length.Download your final video
Perfect for Instagram, TikTok, Threads, UGC, storytelling, tutorials, AI models, and more.
Best Practices for Perfect Results
Choose the right reference image
avoid cropped faces
avoid heavy filters
use sharp, high-quality portraits
avoid sunglasses or large masks
Record clean audio
speak clearly
avoid echo
avoid background effects
keep mouth movements natural
Use prompting effectively
Prompts help but shouldn’t contradict the audio.
Good examples:
“Soft, emotional delivery. Gentle eye movement.”
“Energetic influencer style, smiling while speaking.”
“Serious tone, minimal expression, steady look into the camera.”
Avoid:
“Screaming and jumping” when the audio is calm
Extremely complex camera moves
Physical actions impossible in a portrait frame
For AI models (virtual influencers)
When generating multiple videos for one character:
reuse the same set of reference photos
keep photo style consistent
maintain similar lighting across shoots
🧠 How OmniHuman 1.5 Enhances Lip Sync
This tool is powered by OmniHuman 1.5, providing:
unrestricted character behavior (no movement limits)
improved facial micro-expression realism
understanding of audio meaning, not just sounds
smoother head motion and natural gestures
better identity preservation
strong multi-style support (realistic, cinematic, social-media, vertical video, etc.)
It is the most advanced digital human system currently integrated into our platform.
Troubleshooting
❗ Mouth desync or unnatural lips
check audio clarity
avoid noise-suppressed robotic recordings
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
avoid low-light grainy photos
❗ Emotion not matching
adjust the prompt
avoid conflicting instructions
ensure audio has clear emotion
