What is the best microphone for the camera?

Is the external microphone of Panasonic mdh 1 camera much better than the internal microphone?

Hello, these two microphones have fully met the requirements of daily news interviews and general event records for sound quality, so there is no need to worry about sound quality.

An important difference! The essential difference between the two microphones is that:

The built-in microphone is a stereo non-directional microphone, which means that its focus area will be based on the direction of your camera. The sound in this range will be collected at 90 degrees left and right, and naturally some unnecessary sounds will be collected.

External microphone belongs to directional microphone, and sound reception has strong directivity. Simply put, just like where your microphone is pointing, this microphone will concentrate the sound in this direction. The shape of this area is similar to a heart with a sharp point forward, and the level value of the sound collected outside this area will be greatly reduced, so that the volume of your target area will be highlighted.

For example, when recording an interview in a noisy environment, the sound recorded by a microphone with a built-in non-directional microphone is noisy and cannot highlight the voice of the interview; If an external directional microphone is used, the ambient noise will naturally weaken because the sound receiving area is only a few degrees around the microphone pointing line, and the interview life will naturally stand out.

When shooting with an external microphone, what microphone is the best if the subject is far away from the camera?

When shooting with an external microphone, if the subject is far away from the camera, it is best to use the scenery shooting technology: 1. The meaning of scenery.

It refers to the size of the selected scene range and the area occupied by the subject in the picture, and it is the narrative and structural way of TV photographers.

2. Landscape classification standard

Usually, the scene is divided according to the number of cut parts of the subject (person) in the picture. According to the different styles of modeling and expression, landscape can be divided into two categories: panoramic series landscape and close-range series landscape.

Second, the classification of scenery.

The scene shows the size of the range that the subject presents in the frame. The size of this range is influenced by two factors: shooting distance and lens focal length. On the premise that other shooting conditions remain unchanged, when the subject is far away from the camera, the picture range is large, while the subject size is relatively small, the details are not obvious, and the scene is large; However, when the subject is close to the camera, the obtained picture range is small, the size of the subject is relatively large, and the scene is small.

In the case of the same shooting distance (object distance), we can also use the zoom lens of the camera (zoom lens is widely used in modern cameras, which can realize the continuous change of imaging focal length from several millimeters to one or two hundred millimeters, thus realizing the change of imaging magnification and affecting the scene. Regarding lens imaging and zoom lens, we will analyze it in later chapters. ) realize the scene transformation of the picture. Because short focal length leads to small imaging magnification, long focal length leads to large imaging magnification, so the picture and scene shot with short focal length have a larger range, while the picture and scene shot with long focal length have a smaller range, so the shorter the focal length, the larger the scene, while the longer the focal length, the larger the scene. When the focal length changes continuously, it will form a continuous change of the scene and realize the push-pull of the moving picture.

As mentioned above, the scenes change continuously rather than gradually, so in theory, there is no scientific concept and theoretical definition for the division of scenes. Because of the different usage methods in different occasions, it only has general semantic meaning and creative expression.

In general, we divide the scene according to the number of main body (character) parts intercepted by the picture or the proportion of a main body (scene) in the picture area. What needs to be pointed out in particular is that our division of the scene is only a comprehensive expression of the scope of the subject in the picture, and there is only a relative division in theory and practice, but there is no absolute division.

Scenery can be roughly divided into the following categories: distant view, panoramic view, middle view, close view and close-up. Generally, we call the scenes near the distant view and panorama "big scenes" and the scenes near the close view and close view "small scenes".

1. Vision

Foresight is one of the TV scenes with the farthest visual distance and the largest range of performance space.

In the distant view, the size of the characters in the picture is usually not more than half of the height of the picture, which is used to represent an open scene or a vast space. Therefore, such pictures are more extensive and far-reaching in vision and slower in rhythm, and are generally used to express empty scenes or distant people.

If subdivided from the performance function, the vision can also include two levels: the big vision and the vision. Large vision is generally used to express grand scenes, such as continuous mountains, vast oceans, endless deserts and cities overlooking from the air. Its pictures are sometimes distant and vast, sometimes magnificent, generally slow in pace and easy to express feelings.

Large field of view picture

In the long-term landscape, the space capacity of the picture is very large, the environmental scenery is the main body of the picture, and the characters are just the embellishment of the picture. The composition of the picture depends on the color scale, light-dark relationship, intense dynamic potential, curve and shape changes of the characters and the scene itself, which distinguishes it from other environmental modeling elements.

The subject in this scene is often subordinate to the environment shown in the picture. In contrast, this kind of pictures are mostly scenery-oriented, lyrical and vivid, and characters become the constituent elements in the picture. The grandeur of the scene itself and the smallness of the subject make the scene around the picture look grand and majestic.

Most of the large field of vision is achieved by still pictures or slow translation. Even if the main body of the picture moves violently, it will not affect the composition of the picture.

Compared with the distant view, the difference between the distant view and the distant view is not significant, but in this kind of scene, the proportion of the subject in the picture has increased, for example, the proportion of people in the picture is about half the height of the picture. In this way, although the whole picture is still dominated by distant scenery, due to the enhancement of the visual importance of the subject, we can completely decide whether the subject in the picture is a character or a scenery according to different composition methods and expression purposes.

Perspective pictures don't emphasize the independence of the picture like the big field of vision, but emphasize the correlation between the environment and the characters, the existence of * * * and the rationality of the characters' existence in the environment. In this scene, the main body of the picture is visually prominent. In addition to emphasizing the relationship between light and shadow, color scale, light and shade, and dynamic situation, we should also pay attention to the role of composition forms.

2. Panoramic painting

Panorama is mainly used to show the whole picture or the whole body of the subject, while retaining a certain range of environment and activity space.

For a scene, a panorama is a picture that shows the whole scene. For a character, a panorama is a picture showing the overall appearance of the character. It can not only show the whole picture of a single person, but also show many people at the same time. From the perspective of expressing characters, panorama can also be called "full-length lens". The proportion of people in the picture is roughly the same as the height of the frame.

Compared with the grand vision of the scene, the content of the panorama is more specific and prominent. Whether it is to show scenery or people, panorama pays more attention to the presentation of specific content than to vision. For the panoramic view of the characters, certain environmental content will be kept in the picture at the same time, but at this time, the environmental space in the picture is in a subordinate position, which completely becomes the supplement of the modeling and the foil of the background.

Panoramic picture

Panorama of the characters is often used in the shooting process. This kind of picture focuses the audience's attention on the activities of the characters, which is conducive to better expressing the characteristics of the characters. The panorama above is a typical panorama of people, and the activities of people become the main content of the picture. The environmental content in the picture sets off the scene where the characters are located and plays the role of explanation and explanation.

Therefore, panoramic images can fully explain the close relationship between characters and the environment, and can express specific characters through specific environments, so they are widely used in various movies. Compared with long pictures, panoramic pictures can better show the behavior, expression and appearance of characters, and also show the inner activities of characters to some extent.

Panoramic pictures contain the appearance of the whole character, which is neither too small to be observed well as in the foreground, nor unable to show the morphological movement of the whole body of the character as in close-up pictures. It plays a unique role in narrative, lyric and explaining the relationship between characters and environment.

3. Mid-range shooting

In the middle scene, the overall image and environmental space of the characters have fallen to a secondary position, and it pays more attention to specific actions and plots.

Generally speaking, the middle shot shows the appearance of most characters, because the facial situation is often shown when shooting characters, so the middle shot usually refers to the part above the knee of the character.

The middle scene mainly shows the behavior of the upper body of the character, and in other special cases, it can also show the action form of a part of the character without the head. Compared with the perspective and panorama, the characters in the picture are incomplete, but the images are obviously increased, and the expressions and appearances are clearer. The characters lose their overall image, and the environmental space is not as obvious as the first two scenes, so environmental factors become secondary factors. At this time, the focus of the picture is the performance of the body movements of the characters and the communication relationship between the characters (the middle scene can be single, double, or multi-person in some special circumstances).

medium shot

Because the scenery and environment in the middle scene are in a secondary position, they are mostly in the background, and sometimes they may appear in the foreground according to different situations. Therefore, in actual shooting, due to the influence of different factors such as object distance and lens focal length, the scenery in the picture may be out of focus and form a virtual image. Therefore, the spatial sense of the picture is not strong, and the details of the environmental image may be lost to some extent.

Compared with the distant view and panoramic view, the middle view can see more details of the picture, and the audience's attention is more focused on the main body, so it will be more infectious than the former.

The middle scene is a scene with the strongest narrative function. In the scene containing dialogue, action and emotional communication, the middle scene can be used to express the relationship between characters and between characters and their surroundings in the most favorable and balanced way. The characteristics of the middle scene determine that it can better express the identity, action and purpose of the characters. When showing many people, you can clearly show the relationship between the characters.

4. Close shot

Close shots are often used to show people's facial expressions and emotions in detail.

Close-up is a picture showing the chest of a person or the local appearance of a scene.

When representing a character, the character occupies more than half of the close-up picture. At this time, the head of the character, especially the eyes, will become the focus of the audience's attention. Close shots are often used to show people's facial expressions and emotions in detail. Therefore, a close shot is a kind of scenery that pushes people or subjects to the audience.

In the close-up picture, the environmental space is diluted and it is in the company position. Many times we choose to blur the background by certain means, and all the modeling elements in the background environment only have vague outlines, which is conducive to better highlighting the subject.

What kind of recording equipment do you want to use to shoot and record with a SLR camera?

You need a high-quality external microphone. Say a few models.

1, Sony HS 1 external microphone: This is a zoom external microphone, suitable for Sony digital cameras or SLR with smart slot. The so-called "zoom" means that through the adjustment of the zoom lens, the microphone automatically adjusts the electrolytic capacitance, so that the sound and image are perfectly combined, thus obtaining an excellent and extraordinary atmosphere picture. At present, the retail price in the domestic market is around 650 yuan.

2. Sony Z37C external microphone: This is a thin stick external microphone with a wide receiving range. At present, the retail price in the domestic market is about 1.200 yuan.

3. Sony ECM-MS908C external microphone: This is also a capacitive external microphone with zoom function, which is suitable for all types of SLR cameras with shooting function of Sony digital cameras, such as Sony's TRV 15E digital cameras. At present, the retail price in the domestic market is about 1 100 yuan.

4. Panasonic VW-VMS 1E camera microphone: This is a stereo zoom microphone, suitable for shooting with Panasonic's 3CCD quasi-professional digital camera or SLR camera, such as MX500 and MX350. At present, the retail price in the domestic market is around 900 yuan.

The quality of a video work depends partly on the picture and partly on the audio. If the audio is perfect, the quality of the work will be more professional. So it is very important to capture video and audio better with SLR. From my personal experience in shooting and making videos, low-cost video production (non-professional film and television production process) usually uses several convenient audio solutions:

The directional microphone is installed at the top of the machine.

This is the most commonly used audio receiving method for many video bloggers and photographers. Because the radio microphone inside the SLR camera is very poor, if it is directly used for camera recording, it can only be used as a reference sound at most. If used in the last shot, the effect is very poor, at least I can't accept this rough sound quality at all. If you are online video from the media or sending videos to customers, the direct recording in the SLR camera can be directly excluded, and a special audio solution must be used, and the directional microphone is a very simple and cheap solution. This microphone can be directly installed on the hot shoe interface at the top of the SLR camera, which is convenient to connect and low in cost. Just choose a similar brand of commonly used microphone. In the process of use, it is much better than the camera's own microphone if it involves the close-range voice acquisition of the subject and the small-scale ambient sound reception. Most of Canon's SLRs are equipped with microphone interfaces, which are common with mainstream microphones on the market, so it is relatively convenient to implement. If you don't choose a directional microphone, you can also use a more mainstream recording pen as a microphone. The effect is better than the direct recording in the machine, but the directivity is slightly worse.

Use a wireless microphone.

Wireless microphone broadcasting is a common live broadcast mode in broadcast media. Compared with the microphone installed on the top of the machine, it has obvious advantages: better radio reception effect, longer shooting distance, wider range of activities of the subject and no trouble with wires. Generally, the mainstream brands of wireless microphones are established audio manufacturers, such as Sony and Sennheiser. The most commonly used is "Sony Bee". The use method is also very simple. A transmitter and a receiver are installed on the hot boots of the SLR camera, which are connected with the microphone interface of the camera through the attached patch cord. The transmitter is placed on the subject, and the radio is received through the attached collar microphone, which can be directly wirelessly transmitted from the transmitter to the receiver through the channel, without delay, and the radio receiving effect is excellent. Through my personal long-term use of Bee, I can basically sum up the following characteristics: clear radio reception, simple use, high portability, and strong performance of microphone in eliminating clothing friction noise. If funds permit, this is a highly recommended radio reception method. If there are multiple radio objects, multiple transmitting terminals can be matched.

Add a collar and clip wheat with a recording pen.

The way of recording pen with collar and microphone is very cost-effective, because even a thousand yuan recording pen, such as the low-end model of zoom or tascam, can have good radio reception effect. With an iron triangle collar microphone, the effect is perfect under the condition of low requirements, and even I personally think it is better than a wireless microphone to some extent. The disadvantage of this scheme is that it is troublesome to use. Receiving sound with a recording pen is equivalent to recording separately from a SLR camera. The SLR uses built-in recording, and the recorder also records at the same time, and then aligns the audio later. After the video and audio materials are shot and collected, they are imported into the later computer software. PluralEyes software is recommended to align the audio. That is to say, by analyzing the waveform of the recording recorded by the SLR and the waveform of the audio recorded by the voice recorder, the voice and video can be aligned quickly, and the audio-video matching can be completed relatively quickly.

The above methods of receiving video by SLR are common solutions, and I hope there is a more suitable solution for you.
