Multi-camera recording with outdoor cameras
Here are some key points about outdoor multi-camera recording:
** 1. Equipment preparation **
1. ** Choose the right camera **
- If you were pursuing lightweight personal shooting and wanted a creative high-quality panoramic view, the Shadow Stone Insta360X4 was a good choice. It had 8K30 frame panoramic image quality, small size, and a variety of practical functions, such as selfie stick stealth algorithm, follow-up mode, natural wide-angle FOV mode, disassembled protective mirror, 10 meters waterproof, 130 minutes of battery life, gesture control function, etc. After shooting, you can use Insta360's APP for post-production.
- The PXW-Z280V was a professional camera with excellent performance, flexible operation, and strong environmental adaptability. It had the advantages of advanced technology, durability, high industry recognition, good market use, good cooperation, and strong service ability. It was suitable for outdoor shooting such as news and livelihood programs.
2. ** Check device settings **
- All cameras, except for special positions, should have the same parameters. If they are rented equipment or previously used for other projects, they can be restored to the factory settings first. Special cameras can set different frame rates according to needs. For example, shooting high-speed shows can use 120fps frame rate to shoot slow-motion scenes. However, it is not advisable to set too many different frame rates when multi-camera simultaneous editing, so as to avoid synchronization difficulties.
- Check the audio settings. You can't just pay attention to the audio, but also pay attention to the current sound, low-frequency noise, and microphone spray. At least bring a directional microphone, because the sound quality of the microphone often can't meet the needs, and adjust the audio settings according to the shooting scene (such as the studio or the park).
- Check the storage space. Prepare one or two more memory cards and try not to use the card slot as much as possible because there may be problems with its quality and speed, especially for 4K shooting projects.
- Check the cable of the camera. If you can use the SDI, use the SDI. If you can only use the HDMI, use the strong glue to fix the port to ensure that the cable is firmly connected.
** 2. Equipment connection and signal transmission (Take OBG as an example, it can be adjusted according to the actual broadcasting software)**
1. ** Different types of signal access **
- If you have equipment that supports the NDI-protocol (such as some cameras or computers), you can connect its signal to the broadcasting system through the relevant settings. For example, when creating a new scene in OTS and adding a source to find an NDI-based source (for example, adding an NDI-based signal to the teacher's teaching table: Start OTS → Create a new scene → Add a source in the scene → Find the NDI-based source of the mobile phone → Confirm → adjust the position in the scene).
- For devices that use the SART protocol to transmit video (such as mobile phones with specific apps), the corresponding connection settings must be made. For example, start the relevant APP (such as the Larix Broadcaster app) on the mobile phone to set it up, create a new scene in the OBS on the PC, and create a new media source. Enter the address corresponding to the SART protocol (such as: slt://
Single camera camera recording meeting
There were many factors to consider when recording a meeting with a single camera. First, the equipment and equipment: - In terms of lens selection, if the venue was small or needed to shoot a scene with more than 100 people, a wide-angle lens might be needed. However, conference photography was rarely used. Generally, a full-frame zoom lens with a focal length of 50mm could be selected (for standard lens focal length, it was suitable for taking group photos, portraits, etc.). If there was a C-frame lens with a focal length of 35mm, it was also possible. In addition, it can be equipped with a telephoto lens such as 70 - 200 for long-distance shooting. For the common 18 - 55, 18 - 135 (C frame lens) and 24 - 70, 24 - 105 (full-frame lens) lenses, they were selected according to the actual situation of the unit. The requirements for camera imaging and blurring effects were not particularly high. - It was necessary to have an external flash because most meetings were held indoors. The light from the ceiling light alone could cause uneven light on the face, which could easily produce black shadows. Next was the preliminary preparation: - Arriving at the venue ahead of time, he turned on all the light sources and began to take pictures of the empty mirrors. He took pictures of the banners, slogans, and other elements arranged by the conference team to show the results of the conference team's work. - Communicate with the conference management staff to understand the conference process and the day's activities. - Plan the location of the group photo shoot, understand the number of participants, and arrange the shooting time. - He debugged the machine, checked whether the various equipment functions were normal, measured the light of the conference scene, set the color temperature, white balance shift, and other related parameters, set the camera to continuous shooting mode, and opened the dual format to save photos. Then, there was the filming of the meeting: - After the meeting began, record the people who signed in and punched in. Take pictures of the sign-in scene from multiple angles. Take photos of important leaders in mid-shot and close-up to ensure that the sign-in scene of key people was not missed. - After signing in, according to the angle of the leader's entrance, the leader's entrance image was shot. The middle and long shots were the main shots, and the leader was placed in the middle of the image to ensure that no one else in front of the camera interfered with the overall structure of the image. - If the leader was speaking on the stage, he had to take a panoramic, mid-shot, and close-up shot many times to avoid the appearance of bad images such as closing eyes, squinting eyes, and opening his mouth wide. It was convenient for later selection. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Recording parameters of camera
The camera recording parameters mainly included the following aspects: 1. ** Video format **: There are two types of video, namely, feast and PAL. China (Europe)'s television industry standard was PDA, while the United States (Japan, South Korea, and other countries)'s television industry standard was NSA. The video frame rate that could be selected was 25 frames per second (50 frames, 100 frames) in the PDA format, and 30 frames per second (60 frames, 120 frames) in the NSA format. It was recommended to choose the Polar format for filming in China to avoid the phenomenon of light strobing. 2. ** resolution **: It refers to the number of the number of the displayed image in each picture. It is usually expressed by the product of the number of horizontal and vertical images (for example, 1920X1080) or the number of vertical images (for example, directly marked as 1080). The higher the value, the finer the image and the better the quality. 3. ** frame rate **: For example, 1080P 60fps, 1080P 30fps, etc., often appear together with the resolution. 4. ** Bitrate (Bitrate)**: This is also a setting that needs to be selected before shooting a video. 5. [** USB (Light Speed)**: Can be adjusted in professional video mode or movie mode. When the USB is low (e.g. around 100), the picture will be more delicate, with less noise and higher contrast. However, high sensitivity will easily produce noise. After determining the shutter and aperture, the USB is mainly used to coordinate the light in the picture.] 6. ** Shutter Speed **: Normally, the shutter speed is twice the number of frames. For example, if the video format has a frame rate of 25 frames, the shutter speed can be set to 50. If the shutter speed is lower than this value, the video will have a serious smear effect. If the shutter speed is higher than this value, the image will be clearer. 7. ** Aperture **: The aperture size affects the depth of field effect of the picture. The smaller the aperture, the larger the value, and the deeper the depth of field. The larger the aperture, the smaller the value, and the lighter the depth of field. For example, F5.6 was easy to shoot with a shallow depth of field (the subject was clear and the background was blurry), while F16 had a deeper depth of field. 8. ** Recording format **: If there are no special requirements, you can choose to record a 1920*1080 25 frame MOV format HD video. If there are special requirements for zooming in, you can choose 4K or other format. In addition, when shooting with multiple cameras, it was recommended to set up a unified video recording format to reduce the trouble in the later stages. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Recording camera recommended
Here are some recommendations for cameras with recording capabilities: - It was a 1.3-million-pel camera with a rotating lens. It could record and take still images at the same time. The rotating lens could be used for self-portraits. The product weighed 99 grams and had a size of 45.8 x 101.2 x 23.5mm.

The camera is online but not recording
If the camera is online but not recording, there may be the following reasons: 1. * * Not connected to the hard disk recorder **: If the camera is not connected to the hard disk recorder, the video image cannot be stored. You can only watch the real-time image. Just connect the camera to the hard disk recorder. 2. * * Storage device abnormality **: - * * Hard Disk Full **: Unable to store the surveillance content. You can format the memory card or replace it with a larger storage device. - * * Hard Disk Damage **: If there are bad tracks, you can check the hard disk status in the hard disk management menu. If there are no important videos, you can format the hard disk and try to repair it. 3. * * Recording setting problem **: - * * Recording Type Setting **: Check whether you have set it to record all day or motion detection. If it was motion detection recording, it was necessary to check the settings of motion detection, including the time settings (whether to turn it on, whether to set the area, whether to record together, etc.). It would not record when there was no movement. - * * Recording plan related **: Check whether "Plan configuration-Recording plan for activation" is selected, whether the recording type is "Timed", select the timeline, and check whether the timer is set correctly and whether it is copied to all weeks. 4. * * Memory Card Abnormal **: - * * Memory Card Status Abnormal **: You can check whether the current status of the memory card is normal in the "configuration-storage-storage management" section. - * * Memory Card Not Initialized **: This situation may also result in no recording. 5. * * The time displayed on the screen is incorrect **: Check if the system time of the camera is correct. If the time is incorrect, enter the configuration-system-system settings-time configuration to correct the time of the camera. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What kind of tube is better for outdoor cameras?
The outdoor pole camera generally used a plum blossom tube. For example, the seven-hole plum blossom tube could be used for outdoor pole cameras, and the power cable and video cable could be passed through the same tube (if it was a 24V power cable). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What kind of tube is good for outdoor cameras?
The outdoor pole camera can generally use a plum blossom tube. For example, a seven-hole plum blossom tube can be used for the laying of power cables and video cables. For some outdoor camera designs, folding tubes could also be used to dissipate heat and prevent humid air from entering the body. For example, the reflective panoramic network camera used a multi-section foldable tube that could shrink when the outdoor humidity was high. The concave and concave shape of the inner wall prevented humid air from entering the camera equipment. Different tubes had their own advantages under different functional requirements. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The color of the outdoor camera is not right
If the color of the outdoor camera is not correct, you can try the following methods to correct the color: 1. ** White balance setting **: Make sure to choose the correct white balance mode during shooting to adapt to different lighting conditions outdoors. The white balance mode could help the camera correct the color temperature in the scene, making the color more accurate. If the automatic white balance is not accurate, you can manually adjust the color temperature. If the outdoor environment is blue (high color temperature), you can set a higher K value (more than 5500K), and the camera will increase the yellow light to neutralize the blue light in the picture. If the environment is yellow (low color temperature), set a lower K value (lower than 5500K), and the camera will increase the blue light to correct the yellow light in the picture. You can also set the K value to 5500K, so that the camera does not add color, and you can get a WYSIWYG image. 2. ** Adjusting exposure **: If the color in the photo looks very dark or bright, it may be caused by incorrect exposure. By adjusting the exposure, you can improve the overall brightness and color saturation of the photo. 3. ** Saturation and color balance correction **: You can use image editing software to correct the saturation and color balance during post-processing. By increasing or decreasing the saturation, the color could be made brighter or softer, and by adjusting the color balance, the saturation and hue of different colors could be more accurately controlled. 4. ** Using camera functions **: Some Sony-branded cameras have functions such as active D-Lighting, which can enhance the dynamic range of photos and improve the accuracy of color during shooting. If you plan to perform more complex color correction during post-processing, it is recommended to use the RAW format for shooting. The RAW format can provide a larger dynamic range and more color information for post-processing. 5. ** Color Calibrator Tool (if applicable)**: Some cameras may have a Color Calibrator Tool, such as the Color Calibrator Tool Version 2.0 (if the model is supported), which can be used to create a correction LUT (look up table) to achieve high-quality color reproduction. However, a paid license may be required. In addition, there were some color calibrators that were specially designed to match a specific Sony-based camera. They could ensure that the pre-shot color was consistent with the color seen in daily life. They could analyze and compare the Unreal Engine's correction table with the image captured by the camera in the control panel, and then automatically display the difference in charts and graphs. It was also easy to create and output the LUT correction information so that the Unreal Engine could adjust the color. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Conference recording camera software
There were quite a number of conference recording software. For example, OTS Studio was very powerful. It had a lot of functions and could meet many different recording needs. There was also Bandicam, which was easy to operate and the quality of the videos recorded was also very good. In addition, Camtasia was also a good choice. Not only could it record, but it could also be edited later. It was especially convenient. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the format of the camera recording?
There were many video recording format, including AVI, MP4, MPG, Yanfeng, FLV, DV, LV4, LV5, SSDV, etc. In the field of surveillance, the files might not be opened if they were not recorded properly, but it was generally not a problem. Moreover, most hard disk video recorder came with their own dedicated player. When the video was downloaded, some models had already provided the file, most of which were in AVI, MP4, MPG, and DIV format. In addition, different cameras might also support XAVR, H.265 LongGob-I, 12bit N-RAW, ProRes422, and other video format. Some video format also involved different parameters such as the compression method, color depth/color sample/bit rate, resolution/frame rate, etc. These settings would affect the video quality, file size, and post-processing convenience. For example, H.264 (AVR) and H.265 (HEVP) were common coding format. H.265 had a higher compression ratio. All-Intra (Intra) contained complete image information in each frame, which was beneficial for post-processing but had a large file size. LongGobo (Interframe compression) only contained complete image information in some frames, which could greatly reduce the file size. In terms of color depth, 8bit corresponds to 0 - 255 levels, 10bit corresponds to 0 - 1023 levels, and the color sample ratio is 4:2:0, 4:2:2, 4:4:4, etc. The higher the color sample accuracy, the larger the file space. Under the same code/compression, color depth/color sample, the higher the bit rate, the higher the video quality and the larger the hard disk space. Some cameras, such as the XF605, also supported dual-card recording in different format, such as XF-AVI and MP4 simultaneous recording. XF-AVI could be used for post-editing in high-end applications, while MP4 was more suitable for mass communication and review. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
