Kling V4 Flash: limitations and tips

  • Each render is a single clip of 3 to 30 seconds, depending on the model (Muse is always 10 seconds).

  • Photos go in as frames, not as character references: the first photo is the opening frame, and on MiniMax H3, MiniMax H3 Max, Seedance 2.5, Seedance 2.0, Seedance 2.0 Fast, Seedance 2.0 Mini, and Kling V4 a second photo sets the closing frame. Kling V4 Flash, Gemini Omni 1.2 Flash, and Muse take one photo.

  • Hands, fast motion and on-screen text are where current video models slip most often. A simpler action or a second try usually helps.
