Sequences are made up of scenes.
4
And scenes are made up of shots.

Now quiet on set Hello
13
Last time we looked at the physics of sound
14
which is defined as a Disturbance that creates an acoustic wave through an elastic medium like a liquid gas or solid
15
We also looked at various terms
16
that recur in the sound department along with a plethora of equipment that is needed and And finally,
17
we went through the various production sound positions that are available on set.
18
Today, we'll look closer at what the sound crew does on set, and how they adapt to different environments.
19
Let's begin with the general rules for recording sound on set.
20
The sound department's work on set starts long before the recorder starts rolling.
21
Though a sound mixer was likely present during the tech scout for locations, they will begin to look for potential noise issues that could arise on set.
22
If they spot anything, they will communicate them to the locations department.
23
The team will also watch rehearsals in order to get a better sense of how to mic the scene.
24
All to you.
25
Cheers.
26
Far more than my wages amount to.
27
Cheers.
28
Ideally, they will be able to position the shotgun so that it's no more than three feet away from a subject.
29
They can also add plant mics, microphones that are hidden on set to capture the sounds that the shotgun may miss.
30
Here's the mic, right here in the bush.
31
Now you talk towards it.
32
Once more, it is the mixer's job to vocalize if they see a potential sound issue during the run-through.
33
In the long run, vocalizing problems early will help expedite the shooting process, an important quality for a good sound department.
34
Mixer Chris Howland explains.
35
The last thing you can do is slow the train down.
36
And so you're always listening to gauging the tone of the room, trying to read between the lines, because if things change, you need to be able to change with them
37
and you know you can't rely on somebody to just tell you this is what's going to happen.
38
When actors are done with hair and makeup the mixer will then wire them placing the larve in their costumes.
39
It's important for a mixer to be sensitive during the process clearly communicating where they will locate the larve.
40
It's also critical that the larve's placement will have minimal clothing noise.
41
Production sound mixer Tom Williams explains his approach.
42
You're trying to get it right to the edge of a costume
43
when you've only got a millimeter or so to play with.
44
You really need to push it out as much as possible to get as much air on the mic.
45
And it still has to obviously be hidden.
46
Once the actors are miked and the boom operator is in place, in place, the sound department is ready to record.
47
The second assistant camera will slate in front of the camera after the sound mixer confirms they are speeding.
48
Speed!
49
70 Apple, take 3.
50
Ensuring that the post team will be able to sync footage and audio easily.
51
The boom op will usually move the shotgun close to the slate to get the clap, and then move it back into position.
52
When they are ready, they will often announce, Boom, set!
53
Set! And action!
54
While recording the scene, the mixer will watch the levels.
55
They will usually want to keep audio peaks between minus 6 and minus 12 dB.
56
Hitting 0 dB could cause distortion.
57
To ensure distortion doesn't occur, some sound mixers will use limiters.
58
This will prevent peaks but may eliminate dynamism from dialogue, so it's typically used sparingly.
59
The sound department will also want to capture room tone, audio of the set without any other noise.
60
This recording can be used by the post-production sound team in the sound bed of a scene, so there's never total silence.
61
And so cuts between dialogue aren't as jarring.
62
You remind me of the daughter they took away from me.
63
A sound mixer will often remind the assistant director at the beginning of the day that they'll need time for room tone.
64
Hold it, hold it, hold it!
65
What?
66
I still have to record room tone.
67
Okay, okay, alright, everybody...
68
When recording, the boom operator will make sure the microphone is pointed in the same direction it was during the scene
69
to ensure a maximum level of continuity.
70
Mike's in position.
71
Scene six.
72
Room tone.
73
Rolling.
74
Typically, a room tone recording should be about two minutes.
75
A sound department may also record wild takes after a scene is finished.
76
These are certain sounds from a scene that may be hard to recreate in post, but which are also difficult to capture during the scene.
77
This could be the sound of a prop, or even a short line of dialogue.
78
Of course, sound recording differs based on the location.
79
Let's look at best practices for recording interior sound.
80
Usually recording indoors means a recordist has more command over the sound around them.
81
Interior spaces typically have controllable noise, which refers to any noise that can be mitigated by the sound or locations department.
82
This could be the hum of a refrigerator or an HVAC system in a larger building.
83
The crew can often coordinate with the owners of the space to turn off or turn down these noises.
84
The size of the set will play a role in what microphone a mixer may choose.
85
As a general rule, shotguns with fewer ports, the ridges on the side of the microphone, are better for small spaces.
86
For larger spaces, more ports are ideal.
87
This is because ports are used to capture sound coming from the side of a shotgun and cancel it out using phasing,
88
where a sound wave cancels out a specific frequency.
89
Too many ports in too small a space may create an
90
unwanted phase effect since the subject's noise may hit the ports as well due to reverb.
91
Reverb is an important consideration for indoor settings.
92
Short for reverberation, the term refers to the persistence of sound after it is created.
93
is often most prevalent when a subject is surrounded by hard surfaces, which will bounce sound waves rather than absorb them.
94
A sound mixer typically will want to reduce reverb on set as much as possible.
95
Even if a scene may need reverb in the end...
96
Where is Harvey Dent?
97
...that is usually added by sound designers in post so that they may have more control over how it is employed.
98
Where is Harvey Dent?
99
To avoid reverb, a sound mixer will try and cover as much of the set as possible
100
in soft materials that will absorb sound.
101
They may coordinate with the art department to build carpets or curtains into a set.
102
But if that's not possible, they will employ Fernies.
103
Short for furniture pads, these are blankets made for dampening reverb.
104
Sometimes, however, reverb and echo can be utilized deliberately.
105
Mixer Amanda Becks explains her approach for a warehouse concert scene in Mike Mills' 20th Century Women.
106
When we text-outed it, it was an echo chamber, and I pointed out that it was going to sound like an echo chamber, even with bodies, the band was going to have a certain sound.
107
Mike was all about that.
108
Mike did not want it to sound like we were recording this band in the studio.
109
He wanted it to be the space.
110
Another tricky but common interior space is the car.
111
When recording in a vehicle, sound mixers have numerous unwanted noises to contend with and a limited space in which to hide mics.
112
A rule of thumb most mixers employ in cars is to have the microphone pointed away from the engine
113
so that they can avoid that noise as much as possible.
114
Often, mixers will hide laughs in a car's visors.
115
Sound mixer Stéphane Boucher explains furthering this technique for Lucy.
116
The idea was the sun visor, and I was thinking, what about buy a new sun visor,
117
exactly the same one, and then I'm going to destroy it, open it, put a mic inside,
118
close it again and put it in the car.
119
No, this is not possible, lady.
120
This is a police car.
121
Okay, okay.
122
Recording for interior locations requires ingenuity.
123
And so does recording exterior sound.
124
Often recording outside means having far less command over the sounds making their way onto the set.
125
These sounds are called uncontrollable noises and can include anything from a plane flying overhead to a gust of wind.
126
If an outdoor set is near a roadway, traffic sounds will also be a concern.
127
Sometimes this is a controllable noise through ITC,
128
or Intermittent Traffic Control, where the locations department halts the traffic when a take is in progress.
129
Wind is harder to halt.
130
To avoid wind noise, a recordist will usually employ a blimp or a dead cat.
131
A dead cat is a furry covering for a shotgun that cuts down wind from hitting the mic.
132
A blimp is another covering that protects a microphone even more.
133
But the more protection provided by a covering, the more the high frequencies risk getting reduced.
134
So a mixer will typically only use the amount of protection that is absolutely necessary.
135
Wind and other uncontrollable noises can also be mitigated through smart mic placement.
136
On a particularly gusty day, a boom operator may record from below an actor, pointing the shotgun up at them and avoiding the worst of the wind.
137
This is also true if a production is happening on a roof.
138
If there is traffic noise from below, pointing the shotgun upwards will avoid it.
139
A low-cut filter can also be employed to reduce the bass-heavy interference from wind or low hums from machinery.
140
Hi there.
141
How you doing?
142
Recording outside can also require contending with the elements.
143
In these instances, it's important to pay attention to how the equipment is faring.
144
Sound mixer Mark Ulano explains the steps he took when working in the bitter cold for the hateful eight.
145
You have to have a lot of redundancy because things will fail
146
and you have to be very aware of the impact if you work something in the cold, a piece of electronic gear, and then you bring it to a warm place there's going to be condensation inside.
147
So it's like a little rainstorm in your electronics that are designed to make it stop working at the worst possible moment.
148
So you don't do that.
149
You have a set of cold things, you have a set of warm things.
150
The elements can make their own noise too.
151
When dealing with rain, a mixer may use hogs air, fabric which can dampen the sound of droplets.
152
There is only so much a sound team can do for especially difficult settings.
153
The goal is to get usable sound even if it's not perfect.
154
It is one half of a movie, so don't skimp when it comes to capturing it on set.
155
Listen to your sound mixer, otherwise you may pay for it in post-production,
156
which we'll get into on our next episode, Post-Production Sound.
157
Good sound starts with good planning.
158
Get ahead of any audio surprises by using StudioBinder's pre-production software
159
and Take a look at the StudioBinder Academy channel for filmmaker interviews and in-depth tutorials on creating shot lists,
160

161
Until next time, keep your ears open.
162
What's that noise?
163
The mic's picking up her heartbeat.
164
Swell.
165
Thank you.

Phương Pháp Shadowing Là Gì?
Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
