Scenario Video to Mask

Convert a video to a single-channel grayscale mask video (white = visible, black = transparent).

Model ID: model_scenario-convert-to-mask-video

Capabilities: video2video

LLM Markdown: https://app.scenario.com/api/models/model_scenario-convert-to-mask-video/markdown

Parameter	Type	Required	Default	Min	Max	Allowed Values	Description
file	file	Yes	-	-	-	-	Video to convert into a mask
sourceChannel	string	No	auto	-	-	auto, alpha, luminance	Which source channel to use as the mask. ‘auto’ picks alpha when the input has a non-trivial alpha channel, otherwise falls back to luminance. ‘alpha’ requires a video with an alpha channel. ‘luminance’ converts RGB to grayscale.
threshold	number	No	-	0	255	-	Optional binarization threshold (0-255). When set, pixels >= threshold become 255 and pixels < threshold become 0. Leave empty to keep the continuous mask.
invert	boolean	No	false	-	-	-	Invert the mask (255 - value). Useful when the source is darker for ‘keep’.
