Audio keyframing
As you are aware, video clips in the timeline can contain both video and audio. Audio keyframing allows you to change the volume within the clip – not just as a volume level for the whole clip but with varying volume levels throughout the clip.
Let’s start our first exercise:
- Add a clip containing audio to the timeline. It can be a video clip with audio or an audio-only clip – both work the same. I have added a video clip containing audio. For better visibility, you can expand the audio by double-clicking on the audio waveform of the clip or using the Control + S shortcut.
As you know, the faint horizontal white line allows the volume to be changed for the whole clip, but for this exercise, I’ll add keyframes to lower the volume for the second half of the clip.
- With the Option key held down, click on the horizontal white line; a white dot will appear.
- Click a little further along the clip and do the same with the Option...
