- If you're recording, wind can reap absolute havoc
on the audio in your video files.
Now, the best thing to do here is to reduce the wind noise
as much as you can when you're filming outdoors,
you can use things like a windsock or a dead cat
on top of your microphone, not an actual dead cat,
it's like a windsock that goes on top of your microphone.
The other options are to have your talent
who's wearing a mic to have their back to the wind,
you can also hide your lapel microphone,
if that's what you're using, with some duct tape
under your tee shirt, again to remove the wind noise,
and I'll put a link on the screen here now
to a video where I've explained that.
But there are times where you're just gonna have
wind noise in your video footage, especially
if you're using something like a GoPro.
So a good friend of mine, Stig Severinsen,
if you haven't heard of him, google him, check him out,
his website is breatheology.com,
and I'll put a link to that in the description below,
check him out, he's in insane, multiple world record holder,
multiple Guinness world record holder
for breath hold and for free diving,
he's got a breath hold over 22 minutes,
which is just totally insane, awesome guy,
anyway he sent me some video footage shot on two GoPros,
it was filmed on a boat in really windy conditions.
Currently the video footage is unusable
'cause you can't actually hear what he's saying,
as the wind comes in and out, so the purpose of this video,
I'm gonna show you how you can reduce the wind noise
in your video, so we're actually gonna do this
using video editing software, I'm gonna use
Adobe Premier but the tools that I'm gonna use
inside of Adobe Premier, you'll actually find
in most video editing software.
So the purpose of this video is to show you that you can use
the audio editing tools inside of your video editing
software to achieve some great results, avoiding the need
to export to things like Adobe Audition or to Audacity,
or to other professional audio editing software.
You can actually get some great
results within your editing software.
So I've just got Adobe Premier open here
and I've dropped in the two GoPro clips,
and we'll just have a listen to them.

- Please respect this, way too many
beautiful people have lost their--
- [Justin] Okay so you can hear that the wind noise
in these video clips is pretty full-on.
So let's get into tidying it up.
So the first step is to reduce as much of that wind noise
as we can, so to do that, we use a high-pass filter.
So wind noise is typically a bassy sound,
so we're gonna use a high-pass filter
to let all the high frequencies pass through
and we'll filter out the lower, the deeper,
the base sound, the wind noise, by using
the high-pass filter, so we'll drop that on now.
So when we hit play, you can see that straight away,
it's removed most of the wind noise
with that deep, bassy rumble, but it's also reduced
a lot of the talking, so now we play
with the cut-off or the frequency of where
it's actually gonna cut off the bass.
So now with the video playing, we're just gonna adjust
the cutoff frequency by moving it up and down
until you find the best amount or the maximum
amount of wind noise reduced but the vocals
still sound as clean as they can.
So you can see about there, we've reduced
most of the wind noise down to nothing,
but we've also lost a lot of Stig's voice, so the next step
now is to kind of bring that back but also what we've done
is reduced the volume of the overall clip,
so we need to bring that back up as well.
And if we just turn that effect back off now,
you can see the difference just from that one filter.
- Strap on the mask, we can just have it free and--
(wind roaring)
- [Justin] So the next effect we're gonna add in is an EQ,
or an equalizer filter, and we're gonna boost
the bass back up a little bit, but we're also
gonna reduce the amount of treble
so that it sounds more natural.
So I'm gonna start with the high end,
which is the treble and the low end is the bass.
Every clip is gonna be totally different,
the amount of wind is gonna be totally different,
the microphone's gonna be totally different,
so just playing to see what works.
So what we're actually doing is reducing the volume
level on certain parts of this audio track.
So overall, the audio is actually gonna get quieter,
so we gotta keep boosting the volume back up as well.
So just coming to audio effects, to volume,
and just boost that up, so in this case,
we've dropped the volume so much
that just the volume isn't enough,
so I'm gonna max that out at six,
so we come over to channel volume,
and we turn that up as well, if you need to add
more volume back in, then you can go into effects
and add a volume effect back on top of that as well.
So you can see I'm just playing
with the different settings here to achieve the best result
with the minimum amount of effects, and obviously
in the quickest amount of time to get
this footage back to being usable.
- Diver, scuba instructor, or free-diving instructor.
But today's just a basic introduction,
so what we're gonna do is we're gonna dive on a line
that's attached to the boat here, has a big weight on it,
so it goes straight into the abyss, into the deep water,
and we're gonna use a lanyard, so this is a safety device
you strap onto your wrist or to your ankle,
you can put it on your foot as well,
and then this carabiner goes to the main line.
- [Justin] So you can see with just some really minor tweaks
to the equalizer effect, that we're actually able
to extract some much clearer audio back
out of this clip after we had used
the high-pass filter to eliminate the wind noise.
- A lanyard, safety lanyard.
Also, make sure, even though you know it--
- So you can see there that we've actually reduced it
quite a lot and the footage is now usable.
Again, it's not really awesome, but it's more than usable
and more than acceptable for what it is and where
it was shot and the camera that it was actually shot on.
