20 18 "China takes good photos of mobile phones"-video shooting.

IT 168 Evaluation This chapter is the video shooting part of the annual review of 20 18 "China takes good photos of mobile phones". This chapter will show the performance of HTC U 12+, OPPO R 17 Pro, vivo NEX dual-screen version, Huawei Mate20 Pro, Meizu 16th Plus, Nubian X, Glory Magic2, Xiaomi MIX3 and One Plus 6T in video cropping, video focusing, video anti-shake and low light noise control.

I don't know if you have noticed that at present, all brands don't emphasize the ability of video shooting when promoting the camera function of mobile phones, but according to the author's understanding, some users have begun to pay attention to the video shooting function of mobile phones. Especially with the prevalence of Vlog, the photography ability of mobile phones has attracted the attention of many small partners. Therefore, in this horizontal review, we added the comparison of video shooting to show the performance of these 9 mainstream products by video.

Video clipping:

Here, I'd like to tell you what video clipping is. I believe that many friends will find that when most mobile phones switch from taking photos to video shooting, they will not move their positions, and the overall picture vision will change. The reason for this problem is that the amount of data to be recorded in video shooting is undoubtedly huge compared with taking pictures (PS: for example, 1080P 60fps= 1 take 60 photos per second 1080P). Therefore, manufacturers usually try to reduce the utilization of CMOS (1080P photo = 8 million pixels) to ensure the overall shooting effect of video, which is what we call video editing.

Of course, it doesn't mean that 1080P video only needs 8 million pixels. Theoretically, under the same video resolution, the more pixels are used, the higher the video quality will be, which is what is called "oversampling" in photography.

From the above real video clips, we can see that the video clips of HTC U 12+ and one plus 6T are the smallest, which will theoretically make them have stronger image quality performance. The biggest cutting range is Huawei Mate20 Pro.

Video focus:

First, let's take a look at the video focusing part. As the most basic and important part of video shooting, the focusing speed in the process of video shooting can be said to be the dividing line for evaluating whether a product can shoot a good video. As a portable shooting device, mobile phone should have unique advantages in video focusing because of its small CMOS area. So how do these nine products perform in video focusing? Let's take a look!

▲ Video focusing (slow motion contrast)

Thanks to the advantages brought by CMOS area, the actual focusing speed of these nine products is quite good compared with ordinary SLR. After slowing down by 300%, you can also see the difference in focusing speed between the two. Among them, Xiaomi MIX3 has the fastest focusing speed response, followed by OPPO R 17 Pro and HTC U 12+. The slowest focus in the middle is Glory Magic2. After slowing down, we can clearly see that the center of gravity of Glory Magic2 will lag behind.

Video stabilization:

In addition to focusing, anti-shake is also a very important indicator in the video shooting process. After all, not every small partner will specially buy three-axis stabilizers and other related accessories to shoot videos. Of course, many mobile phones are equipped with anti-shake modules such as electronic anti-shake and optical anti-shake. In the process of testing, in order to make the test more objective and fair, we also specially made a bracket for nine products to shoot at the same time. Let's take a look at whether these anti-shake can play a corresponding role in practical application.

▲ Video anti-shake

From the actual comparison, we can see that OPPO R 17 Pro and Meizu 16th Plus perform quite well in the anti-shake test, except for the visual differences caused by different aircraft positions and different video cropping. Among the nine products, Nubian X has the worst anti-shake effect. It seems that Nubian X still needs to be strengthened in this respect.

Low light noise control:

Finally, let's look at noise control in low light. Compared with the environment with sufficient light, the noise control in low light environment tests the ISP algorithm between brands and the actual photosensitive area and imaging quality of CMOS. So let's take a look at the measured results:

▲ Low light and noise control

▲ Low light and noise control (100% clipping)

Judging from the test results, vivo NEX dual-screen version, Meizu 16th Plus and Nubian X are the best performers, which are more accurate in noise control and character skin color restoration. However, Huawei Mate20 Pro and Glory Magic 2 need to be strengthened. Although Huawei Mate20 Pro performs well in sensitivity and skin color, noise control still needs to be strengthened, and Glory Magic 2 needs to be strengthened not only in noise control, but also in focusing accuracy.

Video shooting summary:

For the video shooting, we made the following comments:

The products of the first echelon: OPPO R 17 Pro, Meizu 16th Plus.

Products to be improved: Huawei Mate20 Pro, Glory Magic2

It must be said that compared with the advantages of other projects, Huawei Mate 20Pro and Glory Magic2 still have a lot of room for improvement in video shooting. The excellent performance of OPPO R 17 Pro in video also surprised the author. Whether it is anti-shake, focusing or noise control in dark light, the performance of OPPO R 17 Pro is worthy of recognition. In addition, the author thinks that Meizu 16th Plus should be commendable in video shooting. Although it is slightly worse than OPPO R 17 Pro in focusing, Meizu 16th Plus performs very well in other aspects such as anti-shake and noise control.
