from runcrate import Runcrate

client = Runcrate(api_key="rc_live_YOUR_API_KEY")
job = client.models.generate_video_and_save(
    "street-scene.mp4",
    model="kuaishou/kling-v3-video",
    prompt="Person walking through rainy Tokyo at night, neon reflections on wet pavement",
    duration=8,
    on_status=lambda j: print(f"  {j.status}..."),
)

Tips

  • v3 vs v2.6. v3 has better quality and human motion. v2.6 is faster and cheaper.
  • Duration affects cost. Start with 3-4s clips to test prompts.
  • Motion control. dolly_zoom_in, dolly_zoom_out, pan_left, pan_right, tilt_up, tilt_down, orbit.
