Slow motion camera
The slow-motion camera mainly relied on the principle of high-frame-rate shooting. Normal video frames were usually 24 or 30 frames per second, but slow motion photography required a higher frame rate, such as 120 frames per second. When played at 30 frames per second, the picture would be slowed down by four times. In terms of equipment selection: - ** Cameras **: Many modern cameras and smart phones have high frame rate shooting functions. Some professional cameras can reach 1000 frames per second, and some high-end smart phones support 240 frames per second slow motion mode. When choosing a camera, besides considering the frame rate, one also had to consider the sensor size and image quality. - ** Lenses **: The choice of lens is also very important. The wide-angle lens can capture a wider scene, and the telephoto lens is suitable for shooting distant details. For slow-motion photography, it is recommended to use a large aperture lens to ensure that there is enough light for high-frame rate shooting, and to use a stabiliser or tripod to reduce the shaking and ensure the clarity of the picture. - ** Lighting **: Slow motion photography often requires more light because high frame rate photography reduces the exposure time of each frame. For indoor shooting, you can consider using professional lighting equipment or natural light sources. The high-speed camera could shoot high-speed moving objects (such as shells) with the help of a mirror. For example, when shooting the trajectory of the shell, a deflective reflective mirror could be used to reflect the movement of the shell into the high-speed camera lens. The camera remained still, and the rotation speed of the mirror could be obtained by calculating the flight speed of the shell, the angle of intersection, and the distance between the mirror and the shell. If the motion trajectory of the captured object is constantly shifting (such as playing table tennis), two mirrors can be used to do two-axis movement (X-axis and Y-axis). First, the horizontal image captured by the X-axis is reflected to the Y-axis, and then the Y-axis reflects the horizontal and vertical images to the camera to keep the image in the middle. Early tracking used non-optical motion capture (based on measuring inertia and mechanical motion), while modern optical motion capture tracked movement through software. AI artificial intelligence could identify object characteristics and simulate motion trajectories with computer controlled mirrors to better record high-speed moving objects. In addition, there were also some special camera equipment, such as the Pikfang Pet Short videos Self-made Machine, which had an automatic shooting function. Although it was not a specialized slow-motion camera, it also reflected the development and innovation of the camera equipment. Read more exciting novels for free
Slow motion camera tutorial
The tutorial for shooting slow motion with different equipment is as follows: 1. ** Some Xiaomi phones **: Turn on the camera, click on the top right corner to enter the camera settings, customize the camera function layout, and press and drag the icon to adjust the layout to achieve slow motion shooting. 2. ** Osmo Pocket Pocket Cloud Platform camera, Osmo Action camera, Osmo Mobile phone cloud platform 3, Dajiang drone Mavic Mavic 2 and Mavic Air**: connect the device to the phone, and then operate it in the DJI Mimo App interface to take a slow motion effect. 3. ** Using AI (Take Huawe-related technology as an example)**: - First, the frame information and event information captured by the two cameras were sent to the warping and synthesizing modules. The warping module used the U-shaped network to convert the motion into optical flow representation, and then converted the events into real frames; the synthesis module used the U-shaped network to place the events between two frames and directly generate a new possible frame for each event. - Since the synthesized video might have noise, the third module would use the new information in the second intercept synthesis module to refine the first module, which was to extract the most valuable information from the two generated frames of the same event and perform warping optimization (again using the U-net network to generate the third frame version of the event). - Finally, these three candidate frames were input into an attention-based average module, which used the best part of the three frame representation to form the final frame. Repeating this process for all the events provided by the event camera would produce the final desired result. 4. ** Computer (using PR or FCPX software)**: import the captured footage into the software and change the speed of a certain area of the footage to achieve a slow-motion effect. 5. ** General camera equipment **: - ** Device Selection **: - ** Cameras **: Many modern DSLR cameras and mirrorless cameras support high frame rate shooting, such as the SonyA7S series and Canon Eos R series, which can shoot 1080p or 4K video at high frame rates. Professional cameras such as the SonyFS7 and the Red series can provide higher frame rates and better picture quality, but the price is relatively higher. - ** Lenses **: Fast lenses can perform better in low-light environments, wide-angle lenses are suitable for capturing vast scenes, and telephoto lenses are suitable for capturing distant details. - ** Tripod and Stabilizer **: When shooting in slow motion, stability is very important. Using a tripod can ensure the stability of the camera and avoid blurring the picture due to shaking. - ** Principle **: By shooting a video at a high frame rate (such as 60fps, 120fps, 240fps, or even higher, the standard frame rate for movies is 24 frames per second), and then playing it back at a normal speed during playback, time can be slowed down to capture more detailed movements. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Huawei camera flashes in slow motion
Take the Huawei P30 as an example. When the fluorescent lights were turned on indoors or when the lights were shot at night, there would be flashes when using "slow motion" photography. This was because the frequency of fluorescent lights was generally 50 Hertz, while slow motion video was 120fps or 240fps. This was a normal phenomenon and not a device malfunction. After eliminating this reason, if such a situation occurs when shooting outdoors with good light, you can try to restore all the settings; if the phone has been dropped recently and accidentally breaks the screen or lens, such problems may also occur; if restoring the settings still can't solve the problem, you can contact the official after-sales service. In addition, the slow-motion camera was able to capture the flickering phenomenon of indoor lights because the frame count in slow-motion mode was higher. Similar to fluorescent lights, we couldn't detect when the display flickered, but in the slow-motion high-frame state, these flashes were magnified. The flickering of the screen when the phone was taking slow motion could also be caused by the camera sensor being sensitive to light in high-speed continuous shooting mode, or the shutter speed was fast. Trying to adjust the brightness or reduce the resolution might alleviate it. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
