Wiseflow siliconflow-video-gen

Generate videos via SiliconFlow Video API. Supports text-to-video (T2V) and image-to-video (I2V) using Wan2.2 models. Async: submit job → poll until done → download.

SiliconFlow Video Gen

Generate videos using the SiliconFlow Video API (Wan2.2 models).

Video generation is asynchronous: the API returns a

requestId

immediately, then the script polls the status endpoint until the job completes (status:

Succeed

The generated video URL is valid for 1 hour. The script downloads the video locally automatically.

Run

Note: Video generation typically takes 1–5 minutes. Set exec timeout accordingly (e.g.,

exec timeout=600

# Text-to-video
python3 {baseDir}/scripts/gen.py --prompt "a dolphin leaping over ocean waves at sunset"

# Image-to-video (provide a public URL or local base64 image)
python3 {baseDir}/scripts/gen.py \
  --model "Wan-AI/Wan2.2-I2V-A14B" \
  --prompt "the camera slowly zooms out" \
  --image "https://example.com/my-photo.jpg"

# Custom resolution and output directory
python3 {baseDir}/scripts/gen.py \
  --prompt "time-lapse of a blooming flower" \
  --image-size 720x1280 \
  --out-dir ./out/videos

# Reproducible generation with a fixed seed
python3 {baseDir}/scripts/gen.py --prompt "rocket launch" --seed 42
