videogencn - Chinese Video Generation Skill

Overview

Generate short video clips using Chinese video models across four providers — Alibaba Cloud Bailian (Wan/PixVerse/Kling/Vidu/HappyHorse), Volcengine Ark (Jimeng/即梦), MiniMax (海螺 AI), and Tencent Hunyuan (混元).

Four modes, auto-selected from inputs:

Mode	Inputs	Default model
t2v 文生视频	prompt only	`wan2.7-t2v-2026-04-25` (Bailian)
i2v 图生视频	prompt + `--image`	`wan2.6-i2v-flash` (Bailian)
kf2v 首尾帧	prompt + `--image` + `--last-frame`	`pixverse/pixverse-c1-kf2v` (Bailian)
r2v 参考生视频	prompt + `--ref` (1-7 images)	`pixverse/pixverse-c1-r2v` (Bailian)

Video generation is asynchronous: submit → poll every 10s → download MP4. Result URLs expire after 24h, so the script always downloads immediately.

Local images: Wan/HappyHorse accept base64 data URIs directly; PixVerse/Kling/Vidu auto-upload to DashScope OSS (48h); Jimeng/Hunyuan use base64; MiniMax uploads via its file API.
