连续性剪辑Continuity Editing

连续性剪辑（Continuity Editing）是让多个镜头组接后像在同一时空连续发生的剪法——目标不是炫技，而是让观众忘记剪辑的存在。

• 动作匹配（Match on Action）：在动作进行中切镜——开门的手伸到一半就切到另一侧机位，动作会把剪点"藏"起来。
• 视线匹配（Eyeline Match）：角色看向画外，下一镜给出他看到的东西，观众自动补出空间关系。
• 不越轴（180-Degree Rule）：机位待在动作轴线（Axis of Action）同一侧，人物的左右朝向才不乱；越轴会让观众瞬间迷路。
• 正反打（Shot-Reverse-Shot）：对话场景的骨架——越过甲的肩拍乙、越过乙的肩拍甲，随对话来回交替。
• 景别递进：远、中、近随情绪推进；同景别硬接容易变成跳切（Jump Cut），看着像失误。

Continuity editing makes a string of shots feel like one unbroken flow of time and space — the goal is not flash, but making the audience forget the cuts exist.

• Match on Action: cut while motion is underway — the door-opening hand reaches halfway and you switch to the other angle, so the movement "hides" the cut.
• Eyeline Match: a character looks off-screen, and the next shot shows what they see; the audience builds the space in their head.
• Don't cross the line (180-Degree Rule): keep cameras on one side of the Axis of Action so screen direction stays consistent; crossing it loses the viewer instantly.
• Shot-Reverse-Shot: the backbone of dialogue scenes — over A's shoulder to B, over B's shoulder to A, alternating with the conversation.
• Progress the shot sizes: wide, medium, close move with the emotion; cutting between identical framings reads as a Jump Cut — a mistake, not a choice.
