-: We're in a new section of the Premiere Pro course
and this section is all about audio.
So we're going to learn things like adjusting audio levels,
adding audio effects, making our audio sound better
and even adding music to our videos.
So we're gonna walk through our project
and the first thing we're gonna learn is how
to change the audio levels.
How loud or quiet your audio is,
and there's a number of ways to do this.
So we're going to go through all of the ones that I use,
and sometimes I use all of
these methods in the same project.
Because they do different things.
So if you want to just increase or decrease the volume
of a specific audio clip,
say this very first clip that we have in our documentary.
We have on our timeline, tools to do so.
If you open up your track, your audio track,
so that you can see you audio waveforms,
you should see this little line in the middle.
If you click on that little line and go down or up,
you see these numbers pop up.
There's a number and then dB,
dB is decibel and that's how we measure sound.
So going down will decrease the audio
and going up will increase the audio.
Okay, so you can just literally open up your audio track,
move your mouse over to this line and move up or down.
We can also get in here and do a little bit more advanced
editing, so I'm gonna zoom in here really quick.
So say we're playing though this
and this little peak right here, it's not that loud,
but say we think it's too loud
or you do have a bit of audio that actually is too loud
and you want to lower just that piece.
Well, you could go in here and use the razor tool
to cut around it and then just take your mouse selector tool
and decrease this little bit.
But that's a little bit too much work for me,
so I'm going to take my pen tool,
"P" is the keyboard shortcut to get to the pen tool
and put points on this line.
So I can a point here, I could put a point here,
I could a point here and I could put a point here.
And then I could take my selection tool
and I can decrease this middle point.
These points act as anchors that lock the track audio
to a specific point.
So if you set a point then you're basically saying,
"At this point I want my audio to be at this level."
But you can move these points around,
and if you have two points, you can move the bar
in between the point up or down, 'kay.
This is also another way that you can create
a custom transition
So I'm going to delete this consistent power transition
that we added last time.
And I'm just going to take my pen tool,
set a point there and then take a point there.
And now we have a completely customised audio transition.
And I can take my selector tool and move these around.
Holding Shift will also help you,
because it locks it to that decibel level.
See if I don't hold Shift, how I'm moving it left or right
but it kind of goes up or down in decibel level.
If I hold Shift down, it locks it to that level, zero dB.
What if we want to increase or decrease
all of our clips at once?
One way is by selecting multiple clips,
for us we're just going to select all of our audio clips,
right-clicking them, and doing this Audio Gain effect.
So if we click Audio Gain, we have different options.
If we say "adjust gain by" and then we put a positive or
negative decibel level here, say we go six, then say "okay."
All of these clips and you just saw that the waveform,
the actual audio of these clips, increased.
So we're not just editing the output,
like we did with this bar,
we're actually editing the clip itself
and increasing those audio waveforms by six decibels.
So increasing that, so I'm gonna un-do that
by pressing Command+Z.
Control+Z is always un-do on a PC.
Say we want to edit these a little bit more smartly.
Smartly, intelligently, that's a better word.
We can Select All say "Audio Gain" then let's say
"normalise max peak" sometimes if you're working on
a project and you're screening it at a film festival
or if you're playing it online, they'll ask you
"set the max peak to: negative 12 dB," or whatever it is.
So if we want it to be negative 12 dB, we can say
"normalise max peak to: negative 12" and then say, "okay."
What it does is it finds the loudest point in all of these
clips and it puts that at negative 12 and then it adjusts
all of the other clips with the same amount of reduction.
So if it dropped the max peak, say five decibels to get it
to be negative 12, the output is negative 12.
And we can see the output as negative 12
when we watch through it.
So here on our audio mixer, when you're watching this,
under track two, which we haven't really gone through this,
we will go through this in just a second, a little bit more.
But we have our tracks.
We have one, two, three, four and then our master track,
which combines all of our tracks together.
In track two where our audio is,
you'll see this decibel level bouncing up and down.
Negative 24, negative 17, the max one will now be
negative 12 and the rest of them were decreased accordingly.
Let me just un-do that and just show you the other option,
which is, if we go to Audio Gain and we say,
"normalise all peaks," what this will do is it will look
at the peaks in all of these clips and it will raise
each clip individually to be negative 12.
And this is actually a cool tool to use.
Say you were using multiple interviews in one piece,
for example, if we interviewed Anthony for this documentary
and then we interviewed his wife and his mom and his sister
and we combined it all on one video,
but we shot on different locations,
maybe with different cameras,
maybe with different microphones
and they all recorded at a little bit different levels.
We can select all of them, every clip in the interview and
we can say "Audio Gain, normalise all peaks to negative 10,"
or whatever it is and it will make all
of the audio generally feel the same loudness.
So that's a quick way to make
all of audio sound the same levels.
The last way that I want to talk about changing
the levels is by track.
And that is what this audio track mixer is good for.
So we saw this just recently and we saw that we have our
different tracks, we have our first track one, two, three,
four and they have sliders.
So I'm going to play through this
and I'm just going to decrease this slider
and as I do this, the levels get lower
and lower and lower until they are completely gone.
The reason why I would want to use this is if I have
say, music on one track, interview audio on one track,
background noise and effects on another track.
Typically music is a lot louder when you put it
on your timeline so we may want to just drop down
the entire track level to adjust that audio mix.
And we'll do that in a future lesson
when we add music to our piece.
So this is a great way to edit the track audio,
meaning everything on this audio track will be adjusted.
And we'll learn about audio effects but you can also add
audio effects to an entire track.
If you drop down this little icon right here, it has
this little menu where we can go through
and add audio effects.
If we want to add "reverb" which is sort
of that "echo-ey-ness" that you get from your audio
when you're shooting in a room.
Or if you want to add some filters or equalisation,
which will improve the sound of your audio.
We'll go through this in another future lesson, shortly.
We can add these clips for the entire track,
rather than having to do it through every single
individual audio clip.
This was a big lesson.
Audio editing is very important though,
because audio sometimes is more important than what's
happening on-screen, especially when people are watching
our videos on their little phones, or on their iPads when
they're busy, sometimes people will just listen to the
videos and they don't even watch it
because they have another tab open on their computer.
So having good audio is really important and
now you should know how to adjust
the audio levels of your video.
So the action item for today is just to play around
with the Pen tool, maybe go through the interview that
you've edited so far and if there any peaks that are
really loud or any parts that are really soft,
bring those up using the pen editor.
When I was editing this interview there are some moments
that I had to do that with, because Anthony sometimes
when he gets a little bit more emotional,
he gets a little quieter,
when he's talking about a sad thing.
And then when he's excited and emotional,
he gets a little bit too loud so I had to use the Pen tool
to adjust the levels of this interview.
Thanks for watching and we'll see you in the next lesson
and continue learning about audio editing in Premiere Pro.
