AI-driven tool for seamless object separation and smooth video compositing.
Kling Lipsync targets faithful, structure-preserving generation across video-to-video lipsync and text-to-video pipelines. Built on Kuaishou Technology’s Kling model, it prioritizes temporal coherence, identity stability, and realistic speech articulation, synchronizing mouth shapes to synthesized or supplied speech while retaining pose, lighting, and background. Operating up to 1080p at 30 fps, it avoids unnecessary re-synthesis and minimizes drift, producing believable, production-ready clips. For text-to-video, it leverages Kling’s high-quality generation, then applies precise lip motion alignment to the resulting character performance.
Key capabilities:
Begin with a clear, front-facing video (MP4/MOV), 2–60 seconds, 720p or 1080p, ≤100 MB. Provide concise script text (≤120 characters) for speech, select a voice_id (e.g., oversea_male1, commercial_lady_en_f-v1), choose voice_language (en/zh), and set voice_speed (0.5–2). For text-to-video, first generate the base clip in Kling from your prompt, then apply Lipsync to synchronize the performance with the desired narration.

Kling Lipsync is part of the Kling AI ecosystem that enables realistic lip and facial motion synchronization to speech. Using video-to-video or text-to-video generation, Kling Lipsync can animate facial movements that match spoken audio or TTS-generated speech for use in dubbing, marketing, and social media content.
The Kling Lipsync video-to-video feature aligns lip movements in an existing video with a new or original audio track. By analyzing facial landmarks and timing, Kling Lipsync ensures precise synchronization between the person’s lips and the speech, producing realistic results for dubbing or virtual human creation.
Yes, Kling Lipsync supports a text-to-video mode where you can input text that is converted into speech using text-to-speech technology. The platform then aligns the generated speech with facial movements, resulting in a lifelike talking video that does not require pre-recorded audio.
Kling Lipsync operates on a freemium model through Runcomfy’s AI playground. While free credits are provided to new users, continued or high-resolution usage of Kling Lipsync video-to-video and text-to-video processing may require purchasing additional credits according to the platform’s generation policy.
Kling Lipsync is ideal for content creators, educators, marketers, and animators who want natural-looking lip-synced videos. Whether you’re generating video-to-video dubbing clips or text-to-video educational explainers, Kling Lipsync delivers consistent, identity-preserving results suitable for multiple industries.
Kling Lipsync provides professional-grade output, supporting resolutions from 720p up to 1080p in Pro modes. The model ensures realistic facial detail and smooth transitions, whether in video-to-video conversion or text-to-video generation, maintaining natural lip movement and expression alignment.
Kling Lipsync can be accessed online via Runcomfy’s website and API endpoints. Both video-to-video and text-to-video options are available directly in the browser, and the system performs well on mobile devices, allowing creators to produce synchronized videos from anywhere.
Kling Lipsync performs best on clear, front-facing videos with visible lips and moderate length (typically up to 10 seconds for standard plans). For longer or higher-quality video-to-video and text-to-video sessions, users may need to upgrade plans or consume extra credits.
Compared to earlier or competing solutions, Kling Lipsync offers enhanced precision in both video-to-video and text-to-video modes. Its DiT-based architecture ensures better identity preservation, smoother realism, and flexible API integrations that set it apart in scalability and visual fidelity.
