Kling Lip Sync takes a short video clip and syncs the subject's lip movements to a new audio track you provide. Whether you recorded a great take but ruined the audio, or you want to dub a clip into another language, the model handles the alignment automatically without any manual editing. You can supply a pre-recorded audio file in .mp3, .wav, .m4a, or .aac format, or skip recording entirely and type a script instead. When using text, you select a voice from a curated list of English and Chinese options and set the speech rate to match your pacing. The model works with MP4 and MOV video files between 2 and 10 seconds long, at resolutions from 720p to 1080p. It fits naturally into social media content pipelines, dubbing projects, and any workflow where re-recording on camera isn't practical. Try it on Picasso IA with a short clip and see the difference a clean audio sync makes to your content.
Kling Lip Sync is an AI model that takes a short video clip and aligns the speaker's lip movements to a new audio track, solving one of the most common frustrations in video production: good footage paired with unusable audio. On Picasso IA, you upload your clip, provide an audio file or type a script, and get back a synced version in minutes. It also opens up dubbing workflows, letting you swap the original speech for a different voice or language without re-shooting. No editing software or technical setup is required.
