A key frame is an important concept in the [[video-making process]]. It refers to a specific frame in a sequence where a notable change or development occurs, marking the start or end of a particular motion or transition. In [[storyboard|storyboarding]], key frames are essential because they visually represent important moments within the narrative, helping to outline the flow and timing of scenes. They serve as reference points that guide animators and editors in creating smooth transitions between actions or scenes. By establishing these critical points, key frames facilitate the planning and execution of complex sequences, ensuring that the final video aligns with the intended storytelling and pacing envisioned during the [[video pre-production]] phase.
