Model ID: model_birefnet-v2-video

Parameter	Type	Default	Description
`video`	`assetId`	``	Source video for foreground extraction.
`model`	`string`	`General Use (Light)`	Model to use for background removal. The 'General Use (Light)' model is the original model used in the BiRefNet repository. The 'General Use (Light)' model is the original model used in the BiRefNet repository but trained with 2K images. The 'General Use (Heavy)' model is a slower but more accurate model. The 'Matting' model is a model trained specifically for matting images. The 'Portrait' model is a model trained specifically for portrait images. The 'General Use (Light)' model is recommended for most use cases. `"allowedValues": ["General Use (Light)", "General Use (Light 2K)", "General Use (Heavy)", "Matting", "Portrait"]`
`operatingResolution`	`string`	`1024x1024`	The resolution to operate on. The higher the resolution, the more accurate the output will be for high res input images. `"allowedValues": ["1024x1024", "2048x2048"]`
`outputMask`	`boolean`		Whether to output the mask used to remove the background
`refineForeground`	`boolean`		Refine the foreground for better results
`videoQuality`	`string`	`high`	Video output quality. `"allowedValues": ["low", "medium", "high", "maximum"]`
`videoWriteMode`	`string`	`balanced`	Video write mode for encoding. `"allowedValues": ["fast", "balanced", "small"]`
