Tencent Digital (Su Yang) Many people think that the panoramic camera is "a ball", such as Nokia's OZO, Digital Kingdom's Zeus.
In fact, the non-spherical 360° panoramic camera program is still quite numerous, but these products are relatively large, such as GoPro and Google teaming custom Jump, is a disk composed of 16 GoPro camera array, so in the evaluation of this dimension insta360 4K, this should be the relatively small volume in the non-spherical products currently on the market.
Small size design is very pleasing
Insta360 4K uses a block-like design that is quite satisfactory, and the entire structure is very much like a slab, with splicing up and down.
There is a camera in the upper left corner of the front and back of the fuselage, a cooling fan is built in the lower honeycomb case, a small screen and a power button are on the top, the switch can be pressed for a long time, and the settings are confirmed.
The right side of the fuselage has two navigation buttons, do not think this is a volume key, but used to switch between menus.
At the bottom is a microUSB, microSD, power supply, audio jacks, and 1/4 screw jacks. Fortunately, not all interfaces are useful at the time of shooting.
According to the official data, the camera's overall size is 74.5mm × 158mm × 48mm, I got a piece of mobile power compared to the results, the camera is only 1cm thicker than the mobile power, high about 2cm , And the weight is equal to both.
In other words, if you really want to bring this product out to shoot, it is equivalent to a more mobile power load, compared to those who are often 5 kg, 10 kg or even more heavy equipment, less than 1 kg of Insta360 4K is indeed more It is portable, and this is the advantage of compact design.
Still missing a touch screen
A large mobile power-size Insta360 4K camera contains so many components inside, and the level of industrial design is bright enough, but that doesn't mean that Insta360 is perfect enough on this camera.
Such as the top of the screen, the small is really poor, mobile phones are doing borderless, Insta360 your big border to stay? Don't tell me that there is no border ID.
Without considering the cost, if this small screen can be replaced with a large-size touch screen, it should be very good, and the control party is not convenient to say otherwise, at least to reduce the user's learning costs.
There is also a small detail, the official comes with a storage box, but in most cases this box is not available, such as when charging.
And with the box storage, portability will be weakened, so the product manager can completely consider a separate protective shell for the lens, soft and rigid are okay, so how to prevent the protection of the shell is not worried about the lens wear (I always have an unnatural fear of soiling the camera while holding the machine.) I can carry it with me in my suitcase and schoolbag.
It is relatively difficult to get started
Two F2.0 aperture 230° fisheye lenses with Sony's 8 megapixel CMOS sensor are the core hardware of the Insta360 4K.
Some people may ask, two 230 degrees of the lens stack is not 460 degrees, why the final output of the video is only 360 degrees, very simple, the camera automatically in the splicing overlap the part of the optimization and removal, the final output of the standard 360 ° Panoramic content.
Normally turn on the camera, then use the right navigation key to switch the shooting mode, press the power button to start shooting, the starting cost is quite low.
Of course, before you need a suitable tripod to place the camera, you can also hold it by hand, but to ensure that not shaking is not everyone can do it.
Compared to shooting directly on the camera, using a mobile phone to control the camera through direct WiFi connection should be considered a better way. This is because the camera does not have a viewfinder. After the mobile phone is directly connected, it can use a wireless image instead of a viewfinder. This should be a lot. Why do people prefer GoPro Hero 4 Silver?
If you just shoot, a camera with a tripod, you can basically start shooting, but if you want to do a panoramic broadcast, then you have a lot of extra equipment support.
We tested the process of pushing the flow. After the whole process has been completed, you need at least one router with network, two network cables, a USB network adapter cable, and a PC with good performance, and at the same time, satisfy these conditions. The difficulty is not small.
There are still some small shots in the eight shots.
Back to the core picture quality, the two lens of enterprise-level products can not meet the needs of business users, depending on the specific situation.
For example, if you require quick time, then this product is undoubtedly competent, but if you want 100% absolute quality, considering the edge pixel degradation of the fisheye lens, Insta360 4K may not be able to achieve the target.
If the resolution and splicing effects are extremely demanding, then we must turn to multi-lens products. The more lenses we have, the more images we capture, and the more splicing we have, the more resources we have and the more we can do it. In case you need to have enough storage devices.
Insta360, for us, the biggest advantage is that it can be exported for use. In the past, we tried a third-party solution. On the one hand, the camera was too large, and customs had to be carried by people. On the other hand, it was a late period. Splice time is too long, so real-time splicing plus a compact body is very appetite.
Let me say that the so-called 25fps 4K resolution, the actual output effect is still good, but under normal circumstances we will not be in accordance with this specification to output content, after all, the network bandwidth at this stage is still not up to this standard, friendship tips , will be very card, really a card.
The other extreme is 1080p 60fps output, the effect is relatively general, so the most recommended option is 2K resolution 30fps.
Although it is automatic stitching, if you want to shoot a macro or close shot, you can still clearly see the stitching, but shooting in a large scene is still very good, so this stuff is suitable for shooting without too much detail News broadcast video.
Let's talk about the problem of lens calibration. If it's difficult to accept the stitching, you can try to recalibrate the lens. At this time, you need to take out a few hollow sticker rings that are included with the lens and put them on the two lenses. Then start the lens. The camera's auto-calibration feature waits for completion before taking another shot.
Built-in battery can not meet the need of live broadcasting
Officially tagged Insta360 4K this camera has a battery capacity of 5,000 mAh, and if compared with the mobile phone is large enough, but if compared with mobile power, it is smaller.
Judging from the actual shooting situation, shooting at 2K resolution at 30fps, this battery may be able to withstand about 100 minutes, which is basically the same as the official labeling time.
If you just take a video, the result is still acceptable in 100 minutes. After all, there will be different gaps in the shooting process, and you can even carry multiple devices for time-sharing.
However, if it is used for panoramic broadcast, this level of 100 minutes is not safe, and no one can guarantee that the duration of the program must be less than 100 minutes. For example, most concerts are directed at 200 minutes.
In the process of experience, we thought of a method. Since the battery capacity is not enough to guarantee life, then I will add a mobile power, but I am sorry that this approach is so good in GoPro, Insta360 4K does not support, after connecting the mobile power device Prompt USB connection but does not charge the battery.
We checked from the official, the official input voltage / current is 5V/3A, and the general mobile power is only 5V/2A, so in order to ensure the life, the only way is to use the original power adapter, external power supply, But in that case, in addition to solving the problems of the devices, routers, network cables, and networks mentioned in the previous live broadcast, you have to consider the power supply problem additionally.
On the issue of battery life, Insta360 can consider increasing battery capacity. 200 minutes should be a very good goal, although it may be difficult to achieve.
A small one hundred
The compact body design should be said to be the most outstanding place for Insta360 4K panoramic camera, which has nothing to do with the technology, but rather outstanding portability.
In the past, if you really wanted to go out and shoot a panoramic video, according to our plan, you need at least one suitcase to get the equipment away, and if the battery is compliant, you have to look at whether the security and customs have given it, Insta360 4K does not exist For this problem, it may be sufficient for a photo package.
You may say that Insta360 4K's shooting quality is not as good as the Digital Kingdom's Zeus, nor is it like Nokia's OZO, and enterprise-class users are not costly, so they will give priority to quality assurance, but in fact there is a prerequisite - quality Can it be guaranteed?
Although the Insta 360 4K is not the best solution, the effect can meet the general business content requirements, and in the case that this condition can be satisfied, there is a more important requirement is the rapid output of the content, and this is also the camera's One of the advantages.
So, even if there is no touch screen, even if the battery life is still very good, or the live broadcast may encounter the problem of network bandwidth, but compared to small portable and fast output, these are irrelevant, or both It is tolerable and there are reasons to improve on next-generation devices.
