Inputs:

• src_video
• forground_mask (IMAGE) or foreground_MASK (MASK): The input mask. IMAGE option will automatically convert a black/white image to a mask. At least one option must be given.
• solid_color (optional): The solid color to create a screen. Defaults to Green Screen.
• mask_frame: The input mask's index (defaults to 0). Support first (0), last and middle frame.
• n_warmup: Number of iterations to warm up the model. Defaults to 10.

Your input mask won't actually be in the final matte. Instead, the warmup process generate a new input mask, which is then propagated throughout the video.
