This is a simple workflow for the WAN2.2_T2V_14b and WAN2.2_I2V_14b models, perfect for beginners. Essentially, it’s just a basic workflow that I’ve only slightly modified.
Key features: it works with SageAttention (which roughly doubles generation speed) and is friendly to systems with limited VRAM — it can run even on 8 GB graphics cards. Generating a 5‑second clip at 480×720 resolution takes around 5 minutes, while a 2‑second clip takes about 2 minutes. Hopefully, someone will find this helpful.
When setting up your project, locate the EmptyHunyuanLatentVideo or WanImageToVideo node and adjust the length parameter: - Set it to 33 for a 2‑second video - Set it to 81 for a 5‑second video.
