What is the production process of Hollywood film and television sound?

Now movies will be output in different channels, at least the sound will be output separately. If it's dubbing, just change this line.

Early films did not have this technology, or were dubbed on the basis of complete mixed copies. A typical example is the silent part between dialogues, many of which use the ambient sound of the original sound, which is very abrupt. There are other examples, such as the singing of characters in the original sound, which is more obvious.

It is better to watch the soundtrack of the movie, and watching the dubbing is simply torturing yourself.

These technologies are not difficult, you can understand them after a little careful attention, hehe.

Excuse me, is there a microphone to record conversations and another microphone to record ambient sounds, just like a camera has multiple cameras?

This is unnecessary.

The problem of single machine and multi-machine is the same as that of single machine and multi-machine, and it is simply solved together.

First of all, it can be said that more than 90% of the movies we see are shot by a single camera, and multi-cameras are only suitable for Hollywood, or only for one-time non-renewable big scenes, such as the burning of the Pavilion of Heaven, otherwise photographers will generally not choose multi-cameras, and personally feel that dual cameras are less used than multi-cameras.

The problem of single microphone and multiple microphones is not as principled as the problem of plane position, but it seems really necessary to talk about it in the case of shooting with DV, because it is difficult to use dual microphones in advance (although an interviewer or something can be used). In fact, in a scene with stable sound environment, it is not necessary to record the ambient sound and human voice synchronously. As long as everyone understands this, this problem will be easy to handle.

Just record the ambient sound alone, right?

However, this method mentioned by Fan Fan is indeed used in film production. What I want to say is that a single microphone can achieve the same effect as multiple microphones.

Just record the ambient sound alone, right? [/quote]

Yes, but remember that the premise must be in a stable sound environment.

Fan Fan, August 27th, 2008, 00: 28 p.m.

Thank you, I will pay attention to these problems when shooting things in the future:)

On this issue, because the home video camera is used now, the ambient sound and human voice are recorded together when shooting. Even if an environmental track is recorded separately, the vocal track is still accompanied by environmental sound, so it is difficult to extract the human voice separately. I mean the dialogue shot, so is it necessary to adjust it later to solve this problem?

6: 00 a.m. 5438

If you need pure dialogue sound, you can only use a microphone with strong directivity and add front and back noise filtering. There is no other way.

2: 49 p.m.

So does it mean that the human voice itself is not affected by the environment?

Why do we need pure dialogue? Isn't it enough to have 60% emotional level?

2008-8-28 065438+ 0:05 pm

First of all, it is impossible to have completely synchronous sound, and it is useless to record sound close to that level by technical means, because it is not much different from the dubbing effect in the recording studio. I don't think Zichuan's question is about how to get rid of the ambient sound of the channel, but whether the ambient sound above the channel will affect the channel that simply records the ambient sound. My answer still needs a stable sound environment. As for how to stabilize, I don't mean that two tracks can be matched in scenes with few noise sources and many noises, but it depends on the nature of noise sources. I want to think more and accumulate more experience.

Zichuan 2008-8-28 04: 00 pm16

Thank you mushring, yes, that's actually what I wanted to ask. In a noisy environment, such as the Lanting outside the painting, there was a fierce competition, and the sound came up and down, one after another, so the dialogue sound recorded at that time did not match the environmental sound recorded separately later, and it was awkward to match together, and the sense of space was wrong. Later, I thought that if another machine was used to record the noise during the game as ambient sound, this problem might be solved. In a noisy environment, it is a bit troublesome to use a vocal cord on the reaction lens, and you can't always find the feeling. It seems that there is still too little practice and lack of experience.

This is a question of international channels.

Environmental sound and dialogue are not necessarily recorded simultaneously, but most of them are recorded on the spot, which provides a lot of convenience for making international channel files.

I have studied the international channel documents submitted by several foreign films, and I have also made the international channel documents of China films twice. Almost all of them use this method.

The absolute stability of ambient sound is difficult, but it is not difficult for us to record several relatively stable ambient sounds without transient impact. In general, we can edit several relatively stable environmental sound files to obtain pure environmental sound in a scene to provide international channels.

Teacher Jiang Chong, what about the dynamic effect? I thought it was to get all the tracks and then cut off the dialogue and re-match.

But if so, wouldn't it be a heavy loss? If the dynamic effect is stuck with the dialogue card, it can only be removed if it can't be taken out. . .

A little here, a little there, the water is gone. . .

Jiang Chong 2008-9- 18 165438+ 0:50 pm

International channels are generally divided into several versions.

DME for short,

Digital dialogue

Mobile music

electronic effect

The translated film is mainly a part of the translated language, and many languages regarded as environmental sounds will not be translated. Teacher Zhou seems to have produced a translated film with a sense of space.

At present, few commercial translators in China do well. There were misunderstandings about Hong Kong films in the past, all of which came from translated films.

tod050 1

Teacher Jiang Chong, can you introduce the process of film translation? Well done. What's so good about it?

Thank you teacher! :)

Jiang Chong 2008-9-20 03:33 am

Get a movie remix master.

1\ This master tape is now an engineering file of protools, which contains many audio tracks and various sounds.

2\ Mute the dialogue track on this project document and record the dialogue.

Add a sense of space to the recorded dialogue according to the sense of space of the original sound.

4\ Mix the original other sound output.

That's it in a nutshell. The most difficult technology is

1\ Is the voice and image of the character well grasped?

2\ Is the translation in place?

3\ Is the sense of space good?

4\ Do not change the proportion of various voices in the original film when mixing. At present, this problem is very big. Teacher Wang especially likes to improve the dialogue on the original basis by 10 decibel. Don't say I said it, please look at the translation of Saving Private Ryan. )

00:58 a.m.

Thank you, Mr. Jiang Chong!

I see.

Changing the proportion will change everyone else's previous arrangements and ideas, according to the isosceles curve. . .

It hurts too much. . .

:(

Jiang Chong 2008-9-20 065438+ 0:57 pm

I will post a screenshot of the engineering document for you later today.

tod050 1 2008-9-20 10

Ok, thank you, teacher!

:)

Jiang Chong 2008-9-2 1 03:26 a.m.

This is an engineering document of a three-minute short film. This project is very big and the sound is very complicated.

Jiang Chong 2008-9-2 1 03:36 a.m.

This is a surround sound project, commonly known as dolby digital Stereo, 5. 1 (actually including 6 buses). After the initial mixing, I reduced the number of tracks to about 37. Before initial mixing, the number of tracks is about 170 tracks.

Now the top audio track in the picture is the environmental audio track, followed by the music audio track, accounting for about half, then all kinds of recordings and onomatopoeias (commonly known as sound effects in China, changed to dynamic effects after being approved by Teacher Zhou, and Americans call them sound effects and Foley), and finally the human voice (China often calls it dialogue, Americans often call it dialogue, and some uneducated Americans call it human voice). There is no voice-over in this film (China).

What we are doing now is to export the music to a 6-channel master tape, and no other sounds are needed.

So you see that all the music tracks are solo by me, and the other channels are silent.

Jiang Chong 2008-9-2 1 03:44 a.m.

You will see many tracks of these music, such as brass stringed instruments and woodwind percussion instruments. At different times, the volume is different, the sense of space is different, the proportion of these instruments is different, and the positioning of the surrounding sound field is different. In order to facilitate foreigners to understand the intention of our recording engineer when translating, we mixed these sounds into six channels and put them in six sets of speakers in the cinema. In any case, they can't change the ratio of copper pipes to wooden pipes, and they can only make the music bigger as a whole.

By the same principle, I output human voice to a surround sound main device, and I output other sounds to a surround sound main device.

The outer film surface will get three master tapes of surround sound: music, human voice and other sounds.

According to the sound I provided, they matched the sound and mixed it with my other two master tapes to get the version released by their country.

Generally speaking, it is not recommended to change the voice proportion during mixing. However, due to the pronunciation habit and the stress pitch of the pronunciation notes, appropriate adjustments should be made. For example, people in China like to talk at the top of their voices, so international channels are allowed to be adjusted within a certain range.

00:08 a.m.

Too detailed, thank you, Mr. Jiang Chong!

I mean, in an open space, even if you use a forced microphone and "front and back noise filtering", you can't get pure dialogue sound.

I don't know what kind of noise reduction method mushring is talking about. Can you share it? Is it sampling noise reduction, deisser or deesser?

5: 54 p.m.

Sorry, I know there are many ways to reduce noise, but I'm not as professional as you. I don't know the names of various noise reduction methods, so I can only rely on the sound engineer as much as possible in my work. Now I happen to have this opportunity to learn. I hope to hear the difference between the two ways.

It is only a matter of rights and interests to use a strong directional microphone to filter noise in the early and late stages. I never tend to use this method. There is no other way to mean that this method can obtain pure dialogue sound.

0: 08 pm

How to say sampling noise reduction in English?

Jiang chong 2008-9-22 12:02 am

Sorry, it seems that the voice processing of dialogue does not depend on the "sound recorder". I have never heard of the job of "recording engineer". Please explain.

Answer your questions with an animated version.

Sampling noise reduction and the latter two noise reduction methods are both noise reduction methods, but the principles are different. I really can't find a suitable translation for the last two, so I use the original text on the effector.

A.m. 10: 30

When I was editing, the "sound engineer" was responsible for everything related to sound in the later period, including the sound processing of dialogue. It seems that you don't rely on the "sound engineer" to deal with the white sound. You said you hadn't heard of the job of "recording engineer", and I couldn't help it. When I was working in Shanghai, many people who did related work called it that. Of course, there are other names, but I haven't reached the point where I don't call a woman a woman and think she can't have children.

I still have to ask you for professional vocabulary. It's not just a question of collocation between Chinese and English. I want to know the principles and differences of these methods. I don't have a professional dictionary about recording here, so I can only look up regular vocabulary online.

I can't compare with you in the later stage of voice. I can hear the difference between before and after the sound engineer denoises a conversation, but I only watch people do it in principle and operation. Besides, I was talking about noise filtering. Of course, this is not a deduction.

There are many ways to filter noise in the early stage. I haven't studied related majors, so I'll try to explain it in spoken English. Before shooting, this work has been started from the behavior of screening different websites. Directional microphone itself is a way to filter out many reflected sounds in different directions by pointing at a certain sound source. Laying corrugated cardboard liners on the ceiling, walls and floors or a large number of plastic shells filled with eggs in supermarkets can reduce sound reflection, thus reducing sound noise. Fill and seal the gaps between doors and windows with cotton wool and adhesive tape. Early recording studios could also decorate walls and ceilings with fine wood arranged at a certain distance, and lay carpets on the ground. Nowadays, more and more leather is used as the outer wall. Outdoor, all kinds of wool covers for microphones can filter noise, and some of them are partially carpeted, or a large canvas grille is used on the side of the machine.

The noise was filtered in the early stage, which summed up in a mess.

These methods can be understood as changing the acoustic environment. The materials used mainly absorb reflected sound and high-frequency sound. Because of its short wavelength, it is easy to enter these materials.

The reason of low frequency is difficult to control in the early stage. The method to change the acoustic environment is mainly to improve the low-frequency scattering efficiency and do a good job of low-frequency diffusion of the environment.

The three noise reduction methods I mentioned are the post-processing methods of audio. I'll say it according to my understanding method. Please correct me if I'm not clear.

1\ Sampling noise reduction usually includes ambient sound with or without dialogue in a dialogue sound. Sometimes the environment is too loud for the creator to like. So we choose a section from these ambient sounds, sample their frequencies, and then reduce or completely remove the places with these frequencies from the whole sound. This method is usually called sampling noise reduction. The disadvantage of this method is that if there is a dialogue frequency in the ambient sound, then dialogue.

2\dehisser In our sound world, some types of noise are typical, such as line interference, high-frequency wire sound, ungrounded sound and so on. This effector can effectively suppress these noises and has little effect on the original dialogue. The disadvantage is that the processing range of this kind of noise is limited.

3\deesser is far away from the microphone in the process of recording the conversation, so some sharp lip-tooth sounds in the conversation can be filtered out by this gadget. The disadvantage is that when the sharp lip and tooth sounds are filtered out, the dialogue level of this frequency will also decrease.

At 0: 30 a.m.

Sorry, it seems that the voice processing of dialogue does not depend on the "sound recorder". I have never heard of the job of "recording engineer". Please explain.
