Which tool would you use to add an effect to multiple segments?

To add an effect to multiple segments, the correct tool is the Effect Palette. This tool provides access to a variety of effects that you can apply to clips in your timeline. When working on multiple segments, the Effect Palette allows you to select and drag an effect directly onto those segments or apply it through the Effect Editor. Using this tool enhances your workflow by enabling the application of effects without needing to go through each segment individually, leveraging the efficiency of applying changes across multiple clips simultaneously.

The Segment - Lift/Overwrite function is primarily used for removing or replacing segments in the timeline without necessarily adding effects to them. The Audio Mixer is focused on adjusting audio levels and settings rather than applying visual effects. The Editing Toolbar includes a variety of tools for trimming and adjusting clips but does not specialize in the application of effects.
