Solo and mute audio clips
The solo feature temporarily disables audio playback of all clips in the Timeline except for selected ones. It is especially useful in audio editing if you have more than one audio clip layered in the Timeline (dialogue and background music, for example) but need to listen and make edits to just certain clips.
You can also mute clips by disabling them. Disabled clips are both invisible and silent and do not appear in any output.
Solo clips in the Timeline
Do one of the following:
Choose Clip > Solo (or press Option-S).
Click the Solo button in the Timeline.
The soloed clip appears highlighted, while other clips appear dimmed.
To turn off solo, click the Solo button, or choose Clip > Solo (or press Option-S) again.
Disable clips or ranges
Note: If the selected clips contain both video and audio, and you want to mute the audio only, choose Clip > Expand Audio Components, and select the audio portion only (or drag to select a range).
Choose Clip > Disable (or press V).
Disabled clips are silent and appear dimmed in the Timeline.
To reenable the disabled clips, select them in the Timeline and choose Clip > Enable (or press V).
Silence clips or ranges
You can silence a selected clip or range.
Choose Modify > Adjust Volume > Silence (–∞).
The selection is silenced, and the volume control for the clip or range is set to –∞ dB.
To restore the original audio level for the selected clip or range, choose Modify > Adjust Volume > Reset (0dB).
You can solo video clips in Final Cut Pro. For more information, see Solo, disable, and enable clips.
