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>

In addition, there were some buttons related to photography operations, such as the sensitivity to light button, which was used to adjust the sensitivity of the sensor to light. The higher the sensitivity to light, the more sensitive the sensor to light, and the brighter the photo, but the image noise would also increase. Generally, it was between 200 - 400. When shooting at night, it could be increased appropriately. The BKO button was used to set the camera to first expose one photo according to the light measurement value, then increase and decrease the exposure amount to expose a few photos. It was suitable for situations where the exposure was not certain or the photo was taken with a high light ratio for HVR synthesis. The Qual button was used to select the photo format. For example, the RAW format saved all the data in the shooting scene, which was convenient for later adjustment. <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>
