Zoom in to audio waveforms in Final Cut Pro
For even more precise editing, you can zoom in to audio clips at the audio sample level.
Audio samples show the audio waveform at a fraction of a second (for example, 1/48,000
for audio recorded at a sample rate of 48 kHz).
Zoom to audio samples
1. In Final Cut Pro, choose View > Zoom to Samples (or press Control-Z), so that a
checkmark appears next to the menu item.
Note: The Zoom to Samples feature is enabled by default.
2. Position the playhead over a clip in the timeline.
3. Zoom in until the clip shows a gray overlay indicating the borders of a video frame.
You can continue to zoom in for a closer view of the waveform.
4. Make edits to the clip, or make adjustments to audio effects using keyframes.
Note: Sample-accurate editing (such as cutting with the blade tool or trimming) is
available only for connected audio clips (that is, audio clips not in the primary storyline)
or compound clips that contain only audio.
To turn off zooming to audio samples, choose View > Zoom to Samples (or press
Control-Z).
Navigate by subframe
You can navigate by subframes (which are 1/80 the duration of a video frame).
1. In the Final Cut Pro timeline or browser, position the playhead or skimmer over a clip.
2. Do any of the following:
• Move backward in one-subframe increments: Press Option-Left Arrow.
• Move forward in one-subframe increments: Press Option-Right Arrow.
Tip: For reference when working with video, you can view subframes in the timecode
display below the viewer. In the General pane
of Final Cut Pro preferences, click the Time
Display pop-up menu and choose the subframe option.
