SamplerARVideo - ComfyUI Built-in Node Documentation

The Sampler AR Video node provides a specialized sampling method for autoregressive video models, such as those using Causal Forcing or Self-Forcing techniques. It manages all parameters related to the autoregressive (AR) loop directly within the workflow, making it easy to configure how the model generates video frames one step at a time.

Inputs

Parameter	Description	Data Type	Required	Range
`num_frame_per_block`	Frames per autoregressive block. A value of 1 means the model generates one frame at a time (framewise), while a value of 3 means it generates three frames together (chunkwise). This setting must match the checkpoint’s training mode. Default: 1.	INT	Yes	1 to 64

Outputs

Output Name	Description	Data Type
`SAMPLER`	A configured sampler object that uses the “ar_video” sampling function with the specified autoregressive parameters.	SAMPLER
