text2video tasks-get (round-robin)
python3 {baseDir}/scripts/happyhorse-magic.py text2video-get --task-id "<TASK_ID_FROM_VIDEO_GEN>"Image to Video Generation (happyhorse-1.0-i2v)
Generate video from a first-frame image. Output aspect ratio automatically follows the input image.
First-frame to Video
python3 {baseDir}/scripts/happyhorse-magic.py image2video-gen --prompt "一只猫在草地上奔跑" --first-frame "https://example.com/cat.png" --resolution "720P" --duration 5
python3 {baseDir}/scripts/happyhorse-magic.py image2video-gen --first-frame "https://example.com/landscape.jpg" --resolution "1080P" --duration 10
python3 {baseDir}/scripts/happyhorse-magic.py image2video-gen --prompt "花朵缓缓绽放" --first-frame "https://example.com/flower.png" --duration 8 --no-watermarkOptions
--prompt: Text prompt for video generation (optional but recommended)--first-frame: First frame image URL (required). Format: JPEG/JPG/PNG/WEBP, min 300px per side, max 10MB.--resolution: Video resolution -720Por1080P(default: 1080P). Output ratio follows input image.--duration: Video duration in seconds, 3-15 (default: 5)--no-watermark: Disable "Happy Horse" watermark (default: enabled)--seed: Random seed for reproducibility [0, 2147483647]
Note: There is no --ratio parameter. The output video aspect ratio automatically follows the input first-frame image.
image2video tasks-get (round-robin)
python3 {baseDir}/scripts/happyhorse-magic.py image2video-get --task-id "<TASK_ID_FROM_VIDEO_GEN>"Reference to Video Generation (happyhorse-1.0-r2v)
Generate video from reference images as character/object sources. Use "character1", "character2", etc. in the prompt to reference images by their array order.
Multi-character Reference
python3 {baseDir}/scripts/happyhorse-magic.py reference2video-gen --prompt "身着红色旗袍的女性character1，镜头以侧面中景勾勒旗袍修身剪裁" --reference-images "https://example.com/girl.jpg" --resolution "720P" --ratio "16:9" --duration 5
