WanVideoVACEEncodeMultiGPU

WanVideoVACEEncodeMultiGPU encodes VACE reference inputs for WanVideo workflows while respecting your chosen device. It patches the base encoder to run on the MultiGPU device and to reuse Wan offload settings automatically.

Inputs

Required

Parameter	Data Type	Description
vae	WANVAE	VAE pair to use during encoding.
load_device	MULTIGPUDEVICE	Device that will execute encoding.
width	INT	Target latent width.
height	INT	Target latent height.
num_frames	INT	Number of frames to encode.
strength	FLOAT	Overall conditioning strength.
vace_start_percent	FLOAT	Step fraction where VACE influence begins.
vace_end_percent	FLOAT	Step fraction where VACE influence ends.

Optional

Parameter	Data Type	Description
input_frames	IMAGE	Input frames used for conditioning.
ref_images	IMAGE	Reference imagery to encode.
input_masks	MASK	Masks applied during encoding.
prev_vace_embeds	WANVIDIMAGE_EMBEDS	Prior VACE embeds to reuse or blend.
tiled_vae	BOOLEAN	Enable tiled encode for lower VRAM usage.

Outputs

Output Name	Data Type	Description
vace_embeds	WANVIDIMAGE_EMBEDS	Encoded VACE embeddings for Wan samplers.
