2. Complete the Workflow Step by Step

  1. Ensure the correct version of model file is loaded:
    • 1.3B version: wan2.1_fun_camera_v1.1_1.3B_bf16.safetensors
    • 14B version: wan2.1_fun_camera_v1.1_14B_bf16.safetensors
  2. Ensure the Load CLIP node has loaded umt5_xxl_fp8_e4m3fn_scaled.safetensors
  3. Ensure the Load VAE node has loaded wan_2.1_vae.safetensors
  4. Ensure the Load CLIP Vision node has loaded clip_vision_h.safetensors
  5. Upload the starting frame to the Load Image node
  6. Modify the Prompt if you’re using your own input image
  7. Set camera motion in the WanCameraEmbedding node
  8. Click the Run button or use the shortcut Ctrl(cmd) + Enter to execute generation

Performance Reference

1.3B Version:

  • 512×512 resolution on RTX 4090 takes about 72 seconds to generate 81 frames

14B Version:

  • RTX4090 24GB VRAM may experience insufficient memory when generating 512×512 resolution, and memory issues have also occurred on A100 when using larger sizes
