How to Use Lip Sync AI
1: Upload your input media - either upload a photo (JPEG, PNG, or JPG format, max 10MB) or a video file. Ensure the image or video shows a clear, front-facing face with good lighting and the mouth clearly visible for best results.
2: Upload your audio file - add the speech audio file (MP3, WAV, OGG, AAC, or M4A format, max 20MB) that will drive the lip movements. Use clean audio without background noise for optimal synchronization. The tool supports multiple languages and accents.
3: Select your preferences - choose the AI model (Lip Sync 1.0), select video resolution (480p or 720p), and optionally add a video prompt description that will be saved with your generation in history.
4: Click the 'Generate' button - the AI will process your inputs and automatically sync the lip movements to match the audio. Processing time depends on video length and resolution, with longer videos requiring proportionally more time.
5: Preview and download - once generation is complete, preview your lip sync video result. If satisfied, download the finished video in MP4 format (H.264 or H.265 codec) with resolutions up to 4K, ready to share on any platform.
