Welcome to day six of 12 Days of Tella.

00:02

We're almost at the halfway point.

00:04

Today is the biggest one so, far.

00:06

It's Music.

00:07

Let me show you how it works.

00:08

open up a video in the Tella editor and head to the new audio tab.

00:14

Here you can browse some, background music that we've added for you.

00:19

You can preview the background track, see how it sounds.

00:23

So just hit play.

00:24

Here you can seek along a bit.

00:29

This one's quite a quiet.

00:33

Can browse others?

00:34

Here you can browse the full set of background music that we've added for you.

00:40

And when you find something you like, you can push add.

00:44

And that will add the full track to the full duration of your video.

00:50

And you can also control the volume of the video here as well.

00:55

So if you want this to be louder or quieter, you can adjust this.

01:00

Now you can remove the song like that.

01:02

So if you think, actually I could, I could do something better.

01:05

But you can also upload your own background music.

01:09

So if you've got some branded stuff or something you've made yourself, or some AI generated stuff, you can hit upload.

01:17

And then, I'll just grab this little number that I prepared earlier.

01:22

Now, if your background track is longer than the duration of your video, then we'll just nicely fade it out at the end of the video.

01:32

If your background track is shorter than the duration of your video, then we'll just nicely loop the background track so that you have background music for the full duration of your video.

01:44

Now that we have some music added, let's play back the video and hear how that sounds.

01:55

Let's crank this up a bit.

02:01

You can start to hear it now.

02:04

So we've got this volume control now for your background music, but we've also added additional volume controls for the various other sources or inputs of audio in your video.

02:17

So by default, you can just adjust the master volume, which will control the audio level of your microphone and your system audio.

02:26

So whatever audio you might have recorded from your screen, you can adjust that here.

02:31

But then you can open up the advanced audio settings and then control those individually.

02:36

So if you recorded system audio, but actually that was an accident, you don't want whatever is happening on your screen, you don't want the sound of that coming through.

02:47

Then you can switch this off or lower it, whatever makes sense.

02:52

Maybe your microphone is, not a good one, or you are accidentally sitting too far away from it, then you can adjust the microphone volume.

03:00

You can boost that if you want to get, some more volume out of it or turn it down, if it's too loud.

03:09

The other thing you can do is if you have multiple clips, you can set different combinations of microphone and system audio on a per, clip basis.

03:22

So by default when you're adjusting these, it'll apply to all of the clips in your video.

03:29

But you can then select the adjust this clip only option and what that'll do is it will let you set a volume for just this clip.

03:40

and so you can make manual adjustments on a per clip basis like this.

03:45

So if I change this here all the way down, it is not going to affect the volume of this first clip.

03:53

if I make some changes to a specific clip and I think actually that's not what I want, then I can reset this back to the master volume or the main volume of of the whole video.

04:09

So that is audio and music.

04:14

I think really the only thing left to do right now is crank this puppy up, turn this guy down.
