Which command should you use to overwrite existing clips while pasting?

The command that allows you to overwrite existing clips while pasting is the "Edit > Paste" command. This command directly places the copied clips into the selected timeline track, replacing any existing clips in that space. When you use this option, any clips that are occupying the same timeline position as your pasted clips will be removed and replaced by the new content you're pasting.

In a video editing scenario, this is important because it allows for seamless replacement of clips without the need for additional steps to remove or delete the existing footage first. This functionality is essential for maintaining workflow efficiency when making edits or corrections in a project.

Other options serve different purposes: for example, "Edit > Paste Insert" adds the clips at the insertion point without overwriting, while "Edit > Replace" can often be associated with specific replacements depending on the context or clip selection. "Edit > Duplicate" creates a copy of the selected clips rather than replacing them. Understanding the distinct functions of each command is crucial for effective video editing.
