Why use a camera instead of a video camera to shoot videos now?

The mainstream commercial video shooting and production still need to use special cameras, and only low-cost production and ordinary civil fields use cameras to shoot videos.

Two kinds of cameras are generally used for video shooting in professional fields. One is cameras used in film and advertising industries, such as ARRI, RED and Sony's high-end cameras. Generally, super35mm photosensitive element is used, which has high resolution and professional video performance. They can shoot slowly upgraded videos or record lossless videos in RAW format. The imaging quality of this kind of camera is very high, and the lens can be changed, which matches the pictures taken by high-order focal plane very well. Later, they can carry out a wide range of color matching and key processing to meet the needs of film and television creation. The other is the broadcast-grade camera used in the broadcast media industry, which generally uses the broadcast models of Sony, Panasonic and other manufacturers. The code rate and format of this machine meet the broadcasting standard of the broadcasting system. The machine has small photosensitive elements, is suitable for news interviews and documentary shooting, has a large depth of field and high picture definition, and can match various audio devices, output ports, remote control devices and so on. To meet the needs of the media industry. At present, these two kinds of equipment are still the main equipment in the film and television, radio and television industries, and cameras are only auxiliary equipment.

So what fields are cameras, such as reflective cameras and SLR cameras, used to shoot videos? Generally, it is a low-cost video production for individuals and studios, such as network short video creation, wedding video, and low-cost corporate promotional videos. Why do these fields love to shoot videos with cameras? There are several reasons:

1, the camera's photosensitive element is large in size, which can shoot a shallow depth of field effect like a movie, and the picture has a better impression;

2. Strong light sensitivity and noise control under low light conditions. Because of the traditional small optical sensor camera, some lighting costs can be saved;

3, convenient to carry and high in use flexibility;

4. The post-production pressure of the shooting material is not great, so it can be edited, colored and packaged on a civil computer;

5. It is more cost-effective for cost control to get higher image quality with less investment. Then, since Canon 5d2 set off the upsurge of camera shooting video, various camera manufacturers saw the product competitiveness brought by video function and joined the camera research and development. For example, Panasonic completely locates gh series in the camera sequence, which is equivalent to a camera with perfect performance after equipped with a special base; Sony has gradually decentralized the high-end video technology, adding high-end video capabilities such as upgrading and logging to its α micro single-phase computer, making the camera more cost-effective and facing a wider customer base. Therefore, cameras with lower price and more flexible creation have become the first choice for ordinary video creators and small video studios. Because of its small size and flexible use, the camera has also become an auxiliary model for many professional media and film teams.

1, most people who shoot videos with cameras basically have cameras in their hands and don't want to buy a set of special video shooting equipment, so it is particularly important to shoot equipment that can shoot videos. In addition, SLR cameras and mirrorless cameras have a huge number of lenses, which is very cost-effective for low-end video shooting.

2. Although SLR cameras and mirrorless cameras are not necessarily better than professional cameras in shooting video, it is undeniable that full-frame cameras with cheap large aperture lenses can get shallow depth of field, while professional s35 will get the same shallow depth of field at higher cost, not to mention small-size sensors.

As mentioned above, the lens group is also an important factor. Although the camera lens is not specially designed for shooting video, respiratory effects and focus drift are serious problems, but it is good to get a lot at a low price.

Cameras and cameras have different picture operations and uses. For example, Sony a7m s camera is closer to cameras and professional cameras. It is better than the most common high-definition broadcast cameras in manual professional operation and frame imaging, but it still has a certain gap with professional cameras and professional cameras. The picture shows Sony's miniature cameras/camcorders fs5 and fs7. Their operation is very similar to their own camera a7, and the imaging and shooting effects are not much different. They are definitely not as good as cameras in daily shooting and portability. However, once the rabbit cage and the radio lighting camera stabilizer are added, they are not professional enough or high enough to shoot on the production site or in a small crew. To be fair, as long as it's not a movie camera like Loy or red (the use conditions are harsh. If I had to choose, I would definitely choose a camera to record video …

Looking at the comment area, I have to add two sentences. If Sony's own camera is better than the video camera, then the engineer can stop working. Things are different. You can figure it out after a little thought. A camera and a video camera are two completely different things. I say this because this question is about the advantages of cameras in shooting videos. Although it has become a general entry-level audience, color matching is needless to say. It has nothing to do with this problem at all. I'm just talking about the advantages of cameras ...

Why do many people use mobile phones instead of cameras, and they used to feel professional? This is the development of the times and the promotion of product competitiveness, which is the inevitable result. Cameras will be eliminated, and the final installation of mobile phones will dominate the world.

Nowadays, the photography function of smart phones is quite powerful, which can basically meet many needs, including some quite professional business needs, because as early as the Apple 5S era, some commercial organizations were shooting with Apple phones, because they have met the business needs, but now smart phones have made great progress every year, and cameras have basically stopped moving forward, so now more photography is using mobile phones. Now mobile phones can take pictures of 4K and 8K, but for ordinary consumers, 1080P is quite clear, and 2K has reached or even surpassed the visual aesthetic. The result, of course, is that mobile phones are more convenient photography tools.

This is progress. One product has eliminated another product because of market demand, and it is inevitable that smart phones will become mainstream shooting tools because they are more convenient to carry and have stronger photo-taking ability. So now no one uses a professional SLR, and no one uses a professional camera, which is the reason.

Any product will be eliminated if it is not improved. This is the law of development. As soon as the camera comes out, it will not be professional, but now the mobile phone can become a professional camera. It's that simple.

It can meet the general requirements of shooting video or micro-single with SLR, which is lower in cost and convenient to carry compared with film machine.

When it comes to shooting videos, people often see cameras. The TV station has been using it. Because CMOS is small, the depth of field of the picture brought by the camera is large, but small CMOS also has its advantages and fast focusing speed. Cameras have autofocus function.

Due to the large CMOS size of the camera, the CMOS size of the general s35 movie camera is equivalent to that of the APSc format SLR camera, and it can obtain the same shallow depth of field as the movie camera (that is, the movie sense as everyone said), and the price is only one tenth of that of the movie camera, with good cost performance. Since Canon 5d2, the camera has enhanced the video function, and everyone tries to shoot video with the camera. The camera is easy to carry when shooting video. It won't attract much attention and is very suitable for making some documentaries.

But if it's cheaper to shoot video with a camera, it's not necessarily so. The camera comes with a lens, a recording microphone and various broadcast-level interfaces. You buy a camera, install a battery, and plug in a memory card to use it.

I bought a camera and needed a lens. If you want to get a film-like depth of field (large aperture lens), such a lens is expensive. For example, big ternary, small ternary and so on.

Let's get this straight. Generally, the price of video cameras is 25,000-30,000, which is already available.

A SLR (micro-single) camera costs 1- 1.5 million, with more than 30,000 lenses. And recording equipment and so on. Of course, it's also cheap. You can do the math yourself.

I just mentioned a concept the other day. The imaging area of a large-size sensor is larger than that of a traditional camera. To get the same landscape composition, you must use a lens with a longer focal length. So the most intuitive feeling is that the sensor is bigger and the scene is deeper. The background picture is blurred by shallow depth of field, which can separate the subject from the background, but it is almost impossible for traditional cameras (2/3, 1/2 or even 1/3 inch sensors) to obtain the same shallow depth of field effect at the same shooting position. Therefore, this feature was equivalent to the "cinematic feeling" at that time-this is a kind of texture that is difficult to see on daily TV, even if the depth of field taken by TV cameras is not as good as that of cameras.

The Last 3 Minutes

In fact, looking back at the short film "The Last Three Minutes", although it does have the texture of a movie, this texture lies not only in the shallow depth of field, but also in the story, scheduling, lighting, sound effects, scenery, service and so on. Although it was difficult for ordinary photographers at that time to have such consciousness now, fundamentally speaking, the camera provided a brand-new, more easily realized and closer to film style.

The Last 3 Minutes

In terms of recording format, EOS 5D Mark II at that time was not backward compared with professional cameras on the market. H.264 coded MOV packet format, 8 bits 4:2:0. You should know that DV, DVCAM, DVCPRO, HDV, AVCHD and MPEG HD420 were widely used by industry users at that time. Compared with H.264 of 5D2, these formats have no obvious advantages, and some standard definition formats lose first in resolution. Model (HDCAM, XDCAM HD422, etc. The coding index can completely exceed 5D2, which is several times or even dozens of times more expensive than this machine.

The most popular HD production format is HDV.

When an equipment is cheap, the shooting effect is outstanding, and it can meet the needs of film and television creation, what is the reason not to use it? Just because it has the shape of a camera?

Now the video functions of high-end SLR and mirrorless cameras have been greatly optimized. In design, the video function has been promoted to almost the same important position as the camera function, and it is more and more friendly to film and television producers in operation, function and workflow. Some models even focus on video shooting to attract professional video producers to buy. Why do you consider the video function as a camera? It can only be said that this is the choice of users and the decision of manufacturers.

Cameras are survivors of brutal market competition.

Entering the last topic, the choice of users and the decision of manufacturers are the two major driving forces for the development of cameras so far, and their essence is cruel market competition. In other words, the camera survived today by self-evolution and defeating competitors.

In fact, the design of camera body is not suitable for camera application, and the camera is more suitable for taking pictures, whether it is from holding gestures or monitoring. So many people will wonder, since film and television producers like to shoot videos with large-size sensors, why don't manufacturers directly introduce large-size sensor interchangeable lens cameras with the same price, so that you can shoot in a familiar way and get the high quality brought by the outsole.

Camera manufacturers have never done this before, remember Sony NEX-VG series? NEX-VG 10 is equipped with CMOS of APS size, which is promoted to be closer to the format of Super35 movies. In addition, it is equipped with E-mount interchangeable lens design, H.264 full HD video coding, and it also has better radio equipment than cameras. The price is in the early 10,000 s, which is much cheaper than 5D2. Is it sure to win? Moreover, after VG 10, Sony also introduced VG20, VG30 and even Quan Huafu's VG900, but now looking back, this kind of products not only failed to win, but also made the camera laugh at the end.

NEX-VG 10 was once highly anticipated.

The embarrassment of positioning is one of the biggest problems. The advantage of a video camera is that it combines the functions of taking pictures and shooting, and photographers, cameramen or all-around photographers will consider buying it. However, due to the cost and pricing, the camera function of VG series outsole interchangeable lens cameras has no crushing advantage compared with cameras, and the camera function is not as good as cameras. At the same time, facing the competition with the traditional hand-held camera, he is a bad school child born from internal and external difficulties. But now, Sony VG series cannot be said to be a failure. It is a spoiler product in itself, which not only won some users, but also won time for Sony while promoting E-slot. Behind the success of Sony Quan Huafu's micro-single, there are its market cultivation and technology precipitation that can't be ignored.

Because it is light and easy to carry. But professional production still needs a camera.

In fact, you must use them all. When shooting, you can control the scene with large COMS equipment, but you can't control the camera on the scene.
