Excuse me, but I'm a bit confused about something I've been hearing in the realm of video production. Could you please clarify for me what exactly is meant by the term "alpha" in the context of video? I've heard it mentioned in discussions about special effects and editing, but I'm not entirely sure how it applies or what its purpose is. Any insight you could provide would be greatly appreciated.
