🧠 : Upload a painting of a cat → get a 5-second clip of the cat blinking and looking around.
One of the biggest hurdles in AI video is "morphing"—where objects change shape between frames. Wan2.1 uses an advanced 3D VAE (Variational Autoencoder) and a causal 3D mask mechanism that allows it to maintain the identity of the subject from the first frame to the last. 2.

: It supports multilingual inputs (Chinese and English), allowing for complex scene descriptions that the model translates into consistent video frames. Inference Speed 🧠 : Upload a painting of a cat
You will need custom nodes (e.g., ComfyUI-WanVideoWrapper). The basic workflow: The basic workflow: : umt5_xxl_fp16
: umt5_xxl_fp16.safetensors (or fp8 for lower VRAM) Path : ComfyUI/models/text_encoders/ Note : Wan2.1 uses a specific Google "UniMax" T5 encoder. VAE : wan_2.1_vae.safetensors Path : ComfyUI/models/vae/
: Uses a T5 Encoder to process multilingual prompts (English and Chinese), which are integrated via cross-attention in each transformer block.
: Place umt5_xxl_fp8_e4m3fn_scaled.safetensors in ComfyUI/models/clip/ .
