FCPX 10.1 Control clip audio without detaching audio
It is possible to disable the audio of a clip without detaching it. We’ve struggled with this some time, as after FCP 7, there seemed to be no way to independently control if the audio of an individual clip is active or not. The wrong way to do this, as suggested by other forums, is to take the audio level and just drag it down to -(infinity). This is a problem because if you’ve already adjusted levels, then you’ll have to fix them again.
Instead, use this simple trick:
Double click the audio track in a clip in the timeline while holding the OPTION key down.
The audio must be visible in the clip for this to work and you must click the audio waveform to make this work. If you just double click the audio track in the timeline without holding the OPTION key down, you will not be able to independently select the audio track. If you look at the two pictures on the right, the one with regular double click and the one with OPTION double click, you’ll see there is a small speaker icon in the audio track.
This little audio icon lets you know that you can now disable the audio by hitting the ‘V’ key. Then OPTION+double click the audio to collapse it back.
If that doesn’t work, right click on the clip and select Expand Audio/Video, then select the audio track, and select Expand Audio Components. You will now be able to Enable/Disable the audio track without losing your audio edits by just clicking ‘V’.
Before, we would Detach Audio, then create a compound clip, and enable/disable the audio there. The risk was that the audio and video could be misaligned, causing a sync problem. Using the Expand Audio Components with the OPTION+double click or right click, now the tracks stay attached, just like in FCP 7.
