Final Cut Pro X: View audio waveforms at the audio sample level

View audio waveforms at the audio sample level

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. If the Zoom to Samples feature isn’t enabled, 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 timeline or the 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.
