WebcamCapture - ComfyUI Built-in Node Documentation

The WebcamCapture node captures images from a webcam device and converts them into a format that can be used within ComfyUI workflows. It inherits from the LoadImage node and provides options to control the capture dimensions and timing. When enabled, the node can capture new images each time the workflow queue is processed.

Inputs

Parameter	Description	Data Type	Required	Range
`image`	The webcam input source to capture images from	WEBCAM	Yes	-
`width`	The desired width for the captured image (default: 0, uses webcam’s native resolution)	INT	Yes	0 to MAX_RESOLUTION
`height`	The desired height for the captured image (default: 0, uses webcam’s native resolution)	INT	Yes	0 to MAX_RESOLUTION
`capture_on_queue`	When enabled, captures a new image each time the workflow queue is processed (default: True)	BOOLEAN	Yes	-

Note: When both width and height are set to 0, the node uses the webcam’s native resolution. Setting either dimension to a non-zero value will resize the captured image accordingly.
