Select Video Lip Sync to sync a talking-head video, or Image Lip Sync to animate a portrait photo. Then pick an AI model based on your quality and budget needs.
Add the source video (MP4, MOV, WebM — up to 200MB) or portrait image (JPG, PNG, WebP — up to 20MB) containing the person whose lips you want to sync.
Upload an audio file (MP3, WAV, AAC, M4A — up to 50MB) as the new speech, or switch to Text to Speech mode, type your script, select a voice, and let AI generate the audio for you.
Submit the task and wait for AI processing. Preview the lip-synced result in your browser, then download the finished video ready for social media or production.
For the most natural result, use a front-facing video or portrait photo where the face is clearly visible, and audio with minimal background noise.
