Your first video

This produces the cyberpunk teaser at the top of the homepage.

Code

from strands_sana import sana_video_generate

result = sana_video_generate(
    prompt=("neon rain falling on the streets of a cyberpunk city, "
            "reflections in puddles, holographic billboards"),
    model="sana-video-2b-480",
    steps=10,        # fast
    frames=49,       # ~2s @ 24fps
    seed=99,
    output_dir="./out",
)
print(result)

What you get

{
  "status": "success",
  "path": "./out/sana_video_<ts>.mp4",
  "model": "sana-video-2b-480",
  "frames": 49,
  "fps": 24,
  "duration_s": 2.04
}

MP4 encoding

For real MP4 output (instead of WebP fallback), install the [video] extra:

pip install 'strands-sana[video]'   # imageio + imageio-ffmpeg

Without it, strands-sana writes animated WebP — works everywhere but harder to share.
