覆盖编辑Overwrite Edit

覆盖编辑（Overwrite Edit）把新片段放到时间线的当前位置，直接盖掉原有片段。

• 它是拖拽编辑时默认的编辑类型：把源片段拖到时间线检视器，停在 Overwrite 覆盖区松开。
• 新片段从播放头位置开始，替换掉同位置原本的片段内容。
• 达芬奇的剪辑是非破坏性的，被覆盖的素材仍然存在，随时可以再 trim 回来。

An Overwrite Edit places a new clip at the current position in the timeline, replacing whatever was there.

• It is the default edit type when dragging: drop the source clip on the Overwrite overlay.
• The new clip starts at the playhead and covers the footage that occupied that spot.
• Editing in DaVinci Resolve is non-destructive, so the covered footage can always be trimmed back.
