3/2/2024 0 Comments Final cut audio keyframe![]() You can trim audio clips on the timeline using any of the editing tools described in the timeline editing notes - Roll, Ripple, Slip, Slide and Razor Blade. Just click on one of the larger bars to increase the size of the tracks as necessary. This lets you change the height of the tracks on the timeline, and each of the four bars represents a different track height. Just to the right of the button we clicked to turn on audio overlays is another button which has what looks like a small bar graph on it. ![]() ![]() When working with audio on the timeline it can be useful to have the tracks themselves taller so you can see the waveform more clearly and have greater control over the audio levels. Click the "OK" button at the bottom of the window and you should see the audio waveforms superimposed on the audio clips themselves. Click on the Timeline Options tab at the top of the window, and from the options which appear click the checkbox next to "show audio waveforms". This window allows you to change a lot of aspects of your sequence, but for now we're jsut concerned with the timeline settings. or use the keyboard shortcut Apple-0 to open the settings window. On the menu bar choose Sequence>Settings. If you want to see the waveforms on the audio tracks as well, you need to change the sequence settings. You can change these just as you do in the Viewer window using the pen tool(or holding the option key to temporarily switch to the pen tool). This is the level overlay button, and when you click it you will see the red lines appear on all audio clips on the timeline. In the lower left hand corner of the timeline are a few buttons - the third one in from the left shows a line with a couple little dots on it. Mixing audio levels on the timelineOnce the clip is on the timeline you can change it's levels using the red line/keyframes in much the same way you do in the Viewer window. You can also change the keyframes themselves simply by dragging the dots up or down in the window. You can add keyframes to the line right in the window using the pen tool (available in the tool palette) or by holding down the Option key as you hover your cursor over one of the lines (the cursor will turn into the pen tool temporarily when you do this). Keyframes appear as small dots on these lines. The red line represents the audio level while the purple line represents the pan setting. When you set level or pan using this method you can see them visually represented by thin lines superimposed over the waveform in the Viewer window (5). Now go to a later time in the clip and drag the slider to a different level - a new keyframe will be created automatically at the current time and the audio level will change over time between the two keyframes when you play it back. This sets a keyframe which records that setting at that time. Set the level or pan setting to what you want to start at and click the keyframe button (4) next to it. The first is to use the level/pan sliders and the keyframe buttons next to them to change the level. There are three ways to do this in the viewer window. In addition to setting the overall level of the clip, you can vary the clip's level or pan settings over time by setting audio keyframes. When you have the clip set the way you want it you can drag it to the timeline by clicking on the small icon in the upper right hand corner which has a hand on a speaker (3). You also have sliders at the top of the window (2) which allow you to set the overall level or pan of the clip. In the viewer window you can set in and out points just like you would with a video clip. Editing individual audio clips in the Viewer window When you double-click an audio clip in your browser window it opens up in the Viewer just like a video clip - except instead of seeing the video image you see the audio waveform (1). There's several ways to work with audio in FCP: 1. Editing and Mixing AudioWhile not a full-featured audio editing system, Final Cut has a good set of basic tools which allow you to perform most common audio processing functions.
