How to carry a movie camera?

How to carry the camera on your shoulder?

Practice more and make the right side of your right hand, shoulder, head and neck triangular. Generally, the shoulder will enlarge the lens to the widest and it will be more stable.

When shooting serious scenes, try to shoot some programs steadily. Since they can shake it, let them shake it a little more. You can even reverse the level of the picture from front to back. But you must also pay attention to push and pull when shaking. Only shaking and pushing and pulling can look good. You should have a rhythm and usually look at how other people's shots are taken.

The most important thing is to push the manual to full load 10 minutes, and then slowly increase the time. No matter how good the camera is, it will shake the skilled work for a long time.

Tutorial on the use of shoulder-mounted camera

It is becoming more and more common to shoot comprehensive sports shots through photographers' shoulder-mounted cameras. So how does Sony shoulder camera work? Next, I'll take you through the tutorial on the use of shoulder-mounted cameras. Welcome to study and reference, I hope it will help you.

Tutorial on the use of shoulder-mounted camera

Put the camera on your shoulder, hold the handle firmly with your right hand, control the switch to focus and zoom, and gently support the hood or viewfinder with your left hand to adjust the aperture and focal length in time. In order to ensure the stability of the machine, the machine can be pressed on the cheek, and the position of the shoulder rest can be appropriately adjusted according to the photographer's body shape to meet the needs of the face pressing on the camera body and the eyes pressing on the viewfinder cover.

When carrying the machine on your shoulders, your legs should be spread apart, your center of gravity should be low, and the bottom of the bracket should be large, so that the picture is relatively stable. When the manipulator is moving, the knees should be slightly bent, and the movement of the footsteps should be replaced by the movement of the body as much as possible, so as to reduce the vertical vibration caused by walking. When shooting, in order to make the subject on the screen look the most stable, we should give priority to the wide-angle segment of the lens and change the position as much as possible, instead of frequently using telephoto zoom.

Matters needing attention in the use of shoulder camera

1. When the shoulder-mounted camera runs abnormally, stop using it immediately. Never aim the lens at the sun or strong light for a long time, otherwise the CCD or CMOS image sensor will be permanently damaged.

2, in the process of use and handling, should avoid the strong vibration or impact of shoulder camera. When shooting with a shoulder camera, it is not allowed to put down the tape magazine of the shoulder camera, otherwise it will cause uneven winding, looseness or damage to the tape.

3, don't use the camera to play and search for pictures for a long time, so as not to damage the head. When shooting with a shoulder camera, you should prepare for shooting in advance and try to reduce the number of times you turn it on.

4. When the shoulder camera is connected with other equipment, it can only be turned on after the connection is correct. Turn off the power of the camera after use, cover the lens, and take out the adhesive tape and battery.

5, pay attention to stay away from the magnetic field as far as possible, try not to use the camera in harsh environment. Don't use the camera in stormy days, and don't get it wet.

Classification of HD cameras

HD camera (usually Sony; Panasonic; Canon; Samsung, etc)

High-definition camera (shoulder-mounted) for professional film and television shooting (widely used by Sony; Panasonic series; )

Security gun HD cameras (Sony, Panasonic, Canon, Samsung, etc. There are: Haikang, Dahua, Youshi, etc. ) is applied to the field of monitoring.

Special camera for video communication and video conference room (IVCOO Baifu Evergrande is widely used; Sony; Panasonic; Samsung, etc)

Introduction to DV:

It can be used for high-quality high-definition images, and the captured images can reach the 720-line progressive scanning mode with the resolution of 1280*720 or the 1080 interlaced scanning mode with the resolution of 1920* 1080. Judging from the recording format, there are roughly two mainstream HD cameras on the market, one is the earliest HDV and the other is AVCHD. The former mainly uses magnetic tape as the recording medium, the video coding is MPEG-2, and the collected files are in M2T format (or MPEG format). The latter includes CD-ROM, flash memory, hard disk and other recording media. The video coding is H.264, and the recorded file format is M2TS.

Hd concept

Maybe many people can only vaguely know 1080P or something. When I see digital TV in advertisements, I always say that I support the standard of 1080i/ 1080P. Let's see what 1080i and 1080P mean-1080i and 720p are internationally recognized digital HDTV standards. Where the letter I stands for interlaced scanning and the letter P stands for progressive scanning. And 1080 and 720 represent the resolution that can be achieved in the vertical direction. 1080P is the highest standard home HD signal format at present.

High definition standard

With the development of society, high-definition video surveillance has developed rapidly, mainly to solve the problem that people can't see the "details" clearly in the normal monitoring process. "HD" means "high resolution". The definition of high definition comes from the field of digital TV. HDTV, also known as "HDTV", is the standard format of high-definition television set by the American Society of Motion Picture and Television Engineers. The definition of TV is measured by the number of horizontal scanning lines, and its centralized HD is divided as follows:

(1) 1080i format is a standard digital TV display mode, 1 125 vertical scanning line, 1080 visible vertical scanning line, 16:9, and the resolution is190.

(2)720p format is a standard digital TV display mode, with 750 vertical scanning lines and 720 visible vertical scanning lines, 16:9, resolution 1280×720, line by line /60Hz and line frequency of 45KHz.

trait

First, the image definition is high

High-definition IP network camera, using 5 million pixel progressive scanning CMOS image sensor, can achieve full real-time broadcast quality of 720P( 1280*720 resolution)/1080p (1920 *1080 resolution), which is much higher than the traditional CCD analog camera.

B, the system has strong environmental adaptability.

The system has an adaptive intelligent adjustment mode, which can automatically adjust the camera's aperture, gain, noise reduction and other parameters according to different light environments, and always maintain the most perfect picture effect. Because the system realizes the full digitalization of monitoring from acquisition to storage, the traditional phenomenon that the camera is directly affected by light changes will no longer exist. At the same time, the common video signal interference in line transmission will also disappear completely.

C, vivid color reproduction

The video capture and compression chip used in the system is a world-famous brand from the United States, and it is also a provider of professional broadcast video capture chips such as Sony Panasonic. Color display is comparable to the color reproduction of professional 3CCD camera, and it has absolute advantages in image color fidelity, color information processing, wide dynamic range and system noise reduction.

D, long system life

Because the system adopts CMOS image sensor, the power consumption and heat generation of the camera are low. The stability is also much higher than that of traditional analog cameras. At the same time, because the components are relatively simple, the failure rate is relatively low. POE power supply will be supported, and the power supply will be directly through the network cable, which solves the problem of on-site power supply.

Causes of camera failure

First, the client or the WEB cannot log in.

ActiveX control is blocked under Windows system. When installing WEB control, if a dialog box pops up to prevent the installation of control, you need to check the settings of IE browser. Open the Internet option in the InternetExplore browser, select the custom level, and re-select "Initialize and run the script of ActiveX control not marked as safe" and "Download unsigned ActiveX control" as the prompts. Run InternetExplore browser again after saving. If you have installed 372 1 internet assistant, control shielding software or personal firewall, please turn it off. Then log in again. Please don't log in with a browser other than IE.

Second, IP search tools or central management software can't find the IP of the network camera.

First confirm the network cable and power supply. If the camera still can't find the IP after confirmation, it is necessary to confirm your network segment and see if the network segment of the webcam is the same as that of your computer. If not, you need to change the network segment of the network camera to be the same as that of your computer. So your computer can find the IP address of the webcam.

If the default IP is192.168.1.100 or192.18 [subject to the operating instructions], without changing the default IP.

Third, normal data cannot pass through the switch.

Possible reasons:

1. If it is a Layer 2 switch, check whether the IP address is wrong or VLAN divides access rights.

2. If it is a Layer 3 switch, check whether the MAC address is bound to the switch port?

3. Check the firewall configuration rules

Solution:

1. First use the ping command to test whether there is a timeout error. If it comes out, check whether the network cable is connected properly.

2. If the switch is bound with IP and Mac addresses, you need to configure the port, IP address and MAC address of the switch bound network camera.

3. Check the firewall rule settings of the switch and add the related ports of the network camera. Such as: 3000,3001,3002,3004,80, etc. Otherwise, all packets will be filtered and cannot be reached.

Fourth, after the local debugging program is upgraded, the video cannot be played normally.

Solution: Close all browsing pages, find the following files in the operating system directory: NetClient.dll, NetViewX.cab, NetViewX.ocx files and delete them. Then reconnect the webcam with the browser, and the browser will prompt you to reinstall the playback control.

If you can't browse yet, it is recommended to add the IP address or address segment of the network camera to the trusted site of the browser, and adjust the relevant security options to enable or prompt.

5. In the dim light environment, the infrared hemisphere camera constantly switches between color and black and white.

Cause analysis: uneven ambient light was detected by infrared photoresistor.

Solution: When installing the camera, try not to let the camera lens face the window. In the case of insufficient light conditions, the light coming in from the outside is asymmetric, sometimes dark and sometimes bright, resulting in abnormal photoresistance.

6. After upgrading the camera locally, there was an error accessing the webcam through the browser.

Solution: Delete the browser's cache directly. Specific operation steps: open a browser, select Tools-Internet option, click Delete File in the second item (temporary Internet file), check the option "Delete all offline content", and then confirm. Just log in to the webcam again.

Seven, connect multiple cameras, but only one camera exits the screen and logs in again for circular display.

Because you didn't change the IP and port number of the network camera, because when connecting multiple network cameras, the IP and port number of each network camera can't be the same, otherwise the video of the two cameras will conflict, and the video will be distorted or there will be no video at all.

Eight, after the webcam is connected, the internal network can see, but the external network can't.

There are two factors in this problem.

First of all, there is no port mapping, because the purpose of each camera is to transmit signals and watch them through the monitor. If you don't do port mapping, the signal can't be sent out, so the signal will only be in the internal network, so the external network can't accept the signal, which makes the external network monitor unable to monitor the situation in real time.

Another question is the domain name of your computer. The access address of the webcam is directly linked to the domain name. The access address of the network camera can be your computer's external network IP plus port number, or your domain name information plus port number.

Nine, the image is stuck, paused, and not smooth.

Network reason: first PING the webcam to see if it is lost. If it is lost, first check whether the network cable and network equipment are normal. Insufficient network bandwidth or congestion may also cause the screen to stop.

X. After the high-definition network spherical camera is powered on, there is no self-inspection, no image and no noise.

Possible causes: Incorrect connection of power cord or damaged power supply.

Solution: Please recheck the wiring; Use a multimeter to test the power supply voltage. If the nominal voltage cannot be reached, please replace the power supply that meets the requirements.

Possible cause: the pan/tilt is stuck.

Solution: Please check whether there are foreign objects entering the machine body, check whether all parts are well assembled and fall off, and check whether the connecting hinge of the ball cover is entangled with the tripod head.

Baidu found it, you can have a look. To sum up, you can use your body as a tripod when you can't rely on it, and try to use it when you can rely on it.

Keeping DV stable When we shoot, we also need to keep DV stable, which is also an important condition to keep the image clear. The picture is unstable, people's eyes can't concentrate, and they often feel dizzy. Especially for novices who have not mastered the camera, every shot can be smooth from beginning to end, which is more valuable than shaking and bumping at will.

1, master the correct method of holding the machine. Because digital cameras are relatively small, they are usually operated manually. This is small and light, and the right arm is basically suspended when shooting. It looks relaxed, but it's actually more tiring than shouldering. Therefore, we should pay more attention to the method of holding the camera. When working, hold the camera handle tightly with your right hand. Focus and zoom with your left hand or hold the camera firmly and fix it with a wristband, so that your right elbow is close to your body and your left hand holds the camera. Keep your eyes close to the viewfinder eye mask to keep the camera stable. The brightness and contrast of the electronic viewfinder can be adjusted. The eyepiece of the optical viewfinder also needs adjustment. Turn the adjusting ring of the eyepiece to make the circular outline of the middle image splitter clear.

2, with the help of auxiliary equipment to reduce operational fatigue, it is best to carry a tripod with you when shooting. Because the tripod for photography is easy to carry and can be quickly put away, it is not as heavy as the tripod for TV cameras. Try to use a tripod when you can, so as to reduce the burden. In addition, it is best to prepare a "shoulder rest" for a one-handed camera, and you can rest assured if you put it on your shoulder when necessary. You can also use the surrounding objects to help support, reduce arm fatigue and increase the stability of the machine. For example, indoor shooting can be supported by desktop help. When shooting outdoors, you can use trees, walls, telephone poles, etc. as support. If you really can't find it, you can keep it stable in the following ways. First, hold the camera tightly with both hands, put your arms close to your ribs, and then lift the camera slightly above your chest. Make full use of the performance advantages of DV when shooting, try to avoid using a long focal length and switch to a wide-angle lens, and shoot at a close distance, because the longer the focal length, the smaller the viewing angle, and the slight shaking will make the picture shake badly, while the wide-angle lens has a large viewing angle, which is not easy to detect even if it is serious. When shooting with a wide-angle lens, the picture jitter can be almost ignored.

If your camera has an anti-shake function, turning on this function when shooting with a handset will help to improve its image instability. If there is a Sony camera, press the menu key to display the menu settings in camera mode, turn SEL/PUSHEXEC to select "C", and then press the dial; Turn the SEL/PUSHEXEC knob to select the STEADYSHOT option, and select on from the menu options that appear, as shown in figure 13, which indicates that anti-shake has been started. In this way, you can turn on the digital camera to shoot, and just follow the normal method when shooting.

4. Keep the picture composition balanced. The ordinary photo is crooked, so you can easily turn it back to the horizontal position. But if the image on TV is tilted, it will be much more troublesome. Every time we press the video button, we have to look around to see if the picture taken in the viewfinder is what we need. At this time, we should not only pay attention to the position of the protagonist, but also study the configuration of the whole picture, keep the balance of the picture and the internal relationship between the object elements in the picture, adjust the relative position and size of the composition objects, and determine their respective layout positions in the picture.
