That’s what we’ll look at this month. | + | **We’ve all heard voiceovers on the radio where the music quickly lowers in volume to let the announcer speak over the quietly playing audio in the background.

Obviously, we’ll use a video, playing audio, as our base to work from. I’ve dragged in a video file to Video 1. Now I add a voiceover file to the project. | Obviously, we’ll use a video, playing audio, as our base to work from. I’ve dragged in a video file to Video 1.

Now, with the video audio playing, and the voiceover (shown below), it’ll be a mass of noise. We want to right-click on the video and choose Add Effect > Audio correction > Volume (keyframable). | Now, with the video audio playing, and the voiceover (shown below), it’ll be a mass of noise.

- | Keyframable is something you may remember from previous FCM Kdenlive articles. It means that we’ll be able to set points to control the level of volume. | + | Keyframable is something you may remember from previous FCM Kdenlive articles.

What we want to do is click (in the timeline) where, in the video, we want the volume to begin fading down, then click the large plus (‘+’) icon in the Vk properties.

I’ve set the Gain value (cropped off in the screen) to -22dB. You’ll notice the white line in the video track has lowered – to show, visually, the volume level. | I’ve set the Gain value (cropped off in the screen) to -22dB.

All that’s left is to do the opposite on the other side. A keyframe at the low value (-22dB in my case), and a final one at the 100% (0dB) value. | All that’s left is to do the opposite on the other side. A keyframe at the low value (-22dB in my case), and a final one at the 100% (0dB) value. | ||
- | You can, of course, do a similar thing with your voiceover file to have it fade in as the music fades out. Also, I’ve made my fade outs two seconds long, just to show you how it looks. Your fadeout may be a second. Maybe even less. | + | You can, of course, do a similar thing with your voiceover file to have it fade in as the music fades out.
