Yes. Kling 4.0 renders sound with the picture, so a creator talking to camera about your product is one take of up to 30 seconds, voice included. Hermoso writes the script, casts the creator and renders it on Kling 4.0.

Why Kling 4.0 works for UGC ads

  • Native sound: the lines are spoken in the render, lip movement and room tone included.
  • Vertical 9:16, the format UGC lives in on TikTok, Reels and Shorts.
  • Attach your product (up to 5 images) so the creator holds the real thing.
  • Up to 30 seconds per take, enough for a hook, a reason and a call to action.
