Simultaneous audio and video
Kling 2.6 Pro, released December 2025, introduced simultaneous audio-visual generation to the Kling Pro lineup — audio is not added after video generation but produced in a single pass alongside the visuals. This ensures tight synchronization between lip movements, dialogue, sound effects, and ambient audio. The lip-sync system supports both English and Chinese dialogue, narration, and singing — with accurate tone production for singing content, not just spoken words. At 48 FPS, motion sequences — particularly martial arts, dance, and fast physical action — are rendered with the smoothness typically associated with high-frame-rate broadcast and sports content.Capabilities

Prompting tips
- Include dialogue in quotes — “A character says ‘Welcome home’ warmly” — quoted text is interpreted as a lip-sync target for the audio generation.
- Specify Chinese or English explicitly — “The character speaks in Mandarin Chinese” or “narration in English” ensures accurate phoneme production.
- Singing works — “A singer performs a pop chorus, upbeat tempo, clear pronunciation” will produce tone-accurate singing with synchronized lip movements.
- 48 FPS rewards fast motion — Prompts involving dance, martial arts, and sports produce their best results at 48 FPS. Describe the full action to benefit from the frame rate.
