Kling makes strong visuals but ships silent clips — you still add voiceover, captions and music yourself.
VideoOS routes Kling (plus Veo, Seedance and 15+ engines) through one key and finishes the clip in the same pass: AI voiceover, optional captions, music and brand outro. 2026 reviews consistently flag Kling's audio gap; here the output is a post-ready vertical short, not a raw clip.
