透明度、遮罩與去背¶
The Alpha, Mask and Keying video effects category provides effects and filters to work with the alpha channel of source files or create masks and cut-outs if needed. It forms the prerequisite for alpha compositing[1] or alpha blending or what is more commonly referred to as Chroma Keying. At the end, the results are used to combine one image or video with a background to create the appearance of varying degrees of transparency.
