As the most popular mobile device, mobile phone has become the core tool for information recording and information dissemination.
Therefore, in recent years, mobile phones have made rapid progress in photography and video technology, and the innovation of resolution is the most easily perceived by ordinary people: 1080P, 2K, 4K…… ... ...
Now a small mobile phone can also shoot 8K ultra HD video. The following GIF image gives you an intuitive sense of the obvious difference between 8K and 1080P.
Under the 8K high-definition image, we can see the magnificent scenery of Qinghai more clearly, and feel more realistic color performance and more perfect detail presentation. It can be said that every time we review these videos, it is an exploration of the depths of our memory, as if we had returned to nature.
I believe many people will be surprised that these ultra-high-definition video blockbusters were shot by the production team of China National Geographic magazine with smart phones equipped with Qualcomm Snapdragon 865 mobile platform.
8K ultra-high-definition video, more perfect noise reduction, color reproduction and the improvement of pixel resolution make nature more real in front of us.
As an ordinary user, what changes can the 8K video shooting function of the mobile phone bring to our photography and video shooting?
Recently, a short video was shot. In this video production, the 8K video shooting function of the flagship mobile phone equipped with Qualcomm Snapdragon 865 mobile platform was fully utilized.
Since the hardware can reach the level of 8K video shooting, and it also broadens the scope of the ability of mobile phones to shoot various forms of high-quality video, I will share with you a wave of high-quality video shooting skills that can be accomplished by mobile phones equipped with Qualcomm Snapdragon 865 mobile platform. Please keep them!
0 1 slow motion (high-speed photography)
We are used to the flying time and fast-paced life, but the appearance of "slow motion" photography once again expands the frequency limit of naked eye observation. Let's appreciate the details and strength from this slow-motion image.
No matter how fast the action is, such as running, flying and jumping ... under the "slow motion" photography, our world is quiet, as if the whole world had stopped for us. Let's take a good look at the world.
Shooting experience:
1. The selected theme needs animals or objects moving at high speed.
2. After determining the subject, turn on the slow motion mode of the mobile phone and select 960FPS ultra-slow motion shooting.
3. Find the best shooting angle and predict the movement track of animals.
4. Click Start to quickly transport the mirror with the animals.
Xiaomi 10 speed commemorative edition supports 960FPS super slow motion. In this mode, you can record the wonderful moments when birds fly by and incite their wings to stay in the air. After the shooting is completed, you can enter the photo album and re-select the slow-motion position to improve the shooting efficiency.
It is worth pointing out that this can not be achieved through the software optimization of the mobile phone, because Snapdragon 865 supports native 960 frames, that is, its integrated ISP's powerful computing power can support the mobile phone to achieve 960 frames of video shooting, that is to say, the ISP handles the complete 960 frames captured by the lens, and each frame is full of information.
Hitchcock
We often say, "Don't believe what you hear, but believe what you see."
What the eyes see is usually more real. However, have you noticed that in some classic TV dramas (especially those with suspense), there is such a picture: the size of the central subject (the area of the protagonist in the picture) remains unchanged, and the visual distance is getting farther (or closer), while the background of the picture is getting closer (or farther).
This seems different from the world we see every day.
And this image must be achieved through a shooting technique, that is: Hitchcock shooting.
Explained in more scientific language, it is a kind of sliding zoom shooting technique, which moves forward or backward while sliding zoom, changes the visual angle of the picture, compresses or enlarges the background space, thus creating a sci-fi, cool or nervous lens feeling.
Shooting experience:
1, close to the subject (animal)
2. Turn on the phone recording mode and select 8K recording for shooting.
3. The photographer moves the mirror backward (or forward) at a uniform speed while sliding and zooming, so as to gradually increase the focal length (or decrease the focal length) and ensure that the size of the subject remains unchanged.
Sliding zoom shooting process
Although this is a cool shooting technology, because of the need for sliding zoom operation, many mobile phones are easy to get stuck when switching cameras, resulting in unsmooth pictures.
However, in video shooting, we will find that the zoom of the mobile phone equipped with Qualcomm Snapdragon 865 is particularly smooth. When shooting a video like Hitchcock, we don't need to use the mobile phone stabilizer, but use sliding zoom to complete the shooting.
In addition to the hardware of the mobile phone itself, the new fifth-generation artificial intelligence engine AI Engine integrated by Snapdragon 865 also fully mobilized the support capability of the whole chip, presenting us with a smoother zoom experience.
03 time delay photography
We want to see the changes of the city, the changes of time and space and the turbulent clouds in a short time. This is our favorite: time-lapse photography.
A few minutes, hours or even longer video is compressed into a shorter video, presenting a wonderful scene that can't be detected by the naked eye at ordinary times, which makes us lament the wonderful change of time.
The time-lapse photography function records the change process from sunset to dark.
Shooting experience:
1. It is recommended to start shooting 30 minutes before sunset.
2. After choosing a suitable scene, fix the mobile phone with a tripod.
3. Take Xiaomi 10 Extreme Commemorative Edition as an example, turn on the camera and select the time-lapse photography function in "More".
4. Press and hold the screen to lock the central exposure of the picture and start shooting.
As we all know, time-lapse photography takes a long time, so remind everyone to bring a charging treasure.
Snapdragon 865 can support shooting more than 65.438 billion colors of video materials, greatly improving the dynamic range of chromaticity and brightness, and making the connection between day and night more natural.
04 shift axis photography
When the whole world is presented like a "lilliputian country", such a picture is not only interesting, but also gives the viewer a strong sense of control.
In this picture, buildings, cars and pedestrians are all like actors in the Lilliput Theater, and we are happy to watch all kinds of interesting performances in this world.
Operating steps:
1. The selected shooting location must have a viewing angle overlooking the shooting.
2. After determining the appropriate scene, fix the mobile phone with a tripod.
3. Select 8K video, and press and hold the picture focus to lock the focus.
4. Later, zoom in and blur up and down through the application.
In addition, when shooting off-axis video/photos, it is recommended to shoot from a long distance, and the scene has a size contrast (the main body is small, and the surrounding scene is large), so that the "Lilliput" will be more realistic.
However, axis-shifting photography is not just a micro-movie. The advantages of 8K video are high resolution, large size and high pixel quality. It can not only enlarge the picture, but also ensure the clarity, which will bring more space to the shift effect of post-production!
For example, this video clip directly enlarges the video, and then blurs it with the app behind it, which has the effect of shifting the axis.
In addition to the above video capture functions, you can also:
Recording and shooting
That is, in the process of recording HD HDR video, we can take HD photos at the same time by clicking the button on the side of the screen. This use case is a challenge to the performance of the mobile phone chip ISP, because the ISP has different processing methods for previews, videos and photos, and it also has to solve the problems of power consumption, overall throughput and image quality.
As shown in the figure, Xiaomi 10 speed commemorative edition can take high-definition photos at the same time in the process of 8K video recording, so high resolution can fully meet our daily social sharing. Recording function can record the video process and freeze the beautiful moments at the same time.
The effect of recording while shooting.
Cutting a frame is also a big movie.
In addition, after shooting an 8K video, you can capture any frame and get a clear picture, which is equivalent to a high-definition pixel photo.
Therefore, we can intercept our most satisfactory angles and pictures in a video, and easily obtain large-scale effects that are difficult to achieve with camera functions.

abstract
The video shooting technologies mentioned above, such as slow motion, Hitchcock, shifting axis photography and recording while shooting, have broken through people's habit of observing the world in daily life, which is a visual benefit brought by technological progress.
These creative photography methods, which used to require the purchase of nearly 10,000 yuan of cameras, micro-sheets and video cameras, can now be realized with a mobile phone. We have to sigh that scientific and technological progress has brought us great benefits and more "popular" traditional professional ability.
To integrate these camera functions into a palm-sized mobile phone, in addition to the improvement of the lens module, the core is that the mobile phone must have a very powerful "inner core".
Because video shooting requires much higher computing power of the processor than photo shooting, especially when using slow motion, Hitchcock, time-lapse photography and other functions, it must be based on a processor with strong processing power and AI computing power.
Smart phones equipped with Qualcomm Snapdragon 865 can not only meet our needs for more photography creation, but also process photos and videos at a speed of 2 billion pixels per second, support video shooting up to 8K level, and bring us more differentiated photography experiences with higher quality than traditional mobile phones can.
In addition, when shooting video in low light, the pixel processing ability of mobile phone for noise reduction can be improved by 40%, because the brand-new ISP introduces a dedicated noise reduction core; At the same time, it can not only process pixels globally, but also realize local motion compensation. This can preserve the texture and details well, which will help us to shoot a better quality video.
In the difficult and complicated image data processing, Snapdragon 865 mobile platform can also reduce the power consumption while ensuring the processing speed. This is why many flagship mobile phones choose to carry this chip.
With the rapid development of communication forms, each of us is no longer a simple receiver of information, but a disseminator and recorder of life content. Thanks to the progress of various technologies, we can better record and spread the beauty of life with a mobile phone.
We are still full of expectations for the future image world. But now we are not bystanders, we can also discover and experience the leap of mobile image technology and spread beauty to every corner of the world!
Attention, don't get lost!
