Every time LeTV emerges, the word "ecology" cannot be bypassed. Even if they have just entered the field of VR, they have spared no effort to create a VR ecological chain, to undertake the entire ecology through the VR content platform, so the emphasis on the content is self-evident . Recently, Lei Fengnet editors visited LeTV's VR department, and Wang Yuxi, technical director of the film and television production center, chatted about their progress in content and issues related to content production.

Six months ago, when Lei Fengwang (searching for the "Lei Feng Net" public number concerned) was acquainted with Wang Yuzheng, he was still employed by Tianji Digital in Hong Kong and came to Beijing to participate in a film-related event. At that time, there were not a large number of complete VR works in the entire industry. Some teams were either just involved in the VR industry or were trying to take panoramic shots. But then, when it comes to the earliest days of contact with VR, many teams said that before the 2014 $2 billion acquisition.

Wang Yuxi talked about his exposure to VR at the 2010 Shanghai World Expo.

"At that time, we didn't actually call VR, which was called panoramic video. At the time, panoramic video was presented as a ring curtain. At that time, we had done a 50-meter ring curtain plus sky form. People stood in the ring and dozens of people watched together. Played content."

Speaking, only there was no VR headshot. "People don't realize that this is VR, just call it the ring ."

Maybe we didn’t realize ourselves, we started to like to go to big-screen theaters to watch movies, like to install large-screen TVs at home, and VR panoramic video made the “big screen” deeper again. “It has become 360 ​​degrees. It is in human history. A video experience that is closest to the biology of the person."

The expansion of the screen has had an impact on the shooting of traditional film works, and has a different influence with 3D.

"It's hard to manage, a new thing comes out and everybody looks at it and doesn't know what to do. But the things that VR shows have brought us far more feeling than 2D or even 3D images themselves. Even if they shoot some without any storyline Everything can feel the huge impact of VR."

For such an impactful technology, Wang Yuxi, a traditional filmmaker, admits that he hopes it will bring some innovations to the film. "Avatar" makes 3D technology known to everyone. Soon mobile phones and TVs are all developing in 3D. However, except for movie theaters, other developments are not good. In some respects, 3D is not as good as 2D, but VR and 3D Differently, the impact it brings, the immersion of experience far exceeds the traditional content.

However, how big the “impact” is and how challenging it is. At some events, the makers of VR content have “drained hardships,” such as the absence of a director, the monitoring of the screen, the display of lights, etc., which are problems that everyone will encounter. Wang Yuxi also mentioned other more realistic issues.

“Before we took a low-cost film, not much money, just make sure the scope of the camera can be seen in the scope of the scene. I shoot this one with a telephoto lens, to ensure that this piece is good-looking, it is all right around the garbage.

Can not VR.

“The surrounding 360-degree scene should be beautiful, otherwise the whole film is very low, so the cost will increase .”

In addition, in the later period of stitching, if the screen is stitched to a large size, the actor will feel a shadowy avatar in the middle of the stitching, and in addition to the 3D effect, the first person view will face various problems. At the same time, the shooting material has increased several times, which also brings a lot of pressure for later content. "Cameras have an average of 6 to 8 stitches, and material grows 6 to 8 times. The huge amount of data slows down the shooting."

In addition to the content shooting and production team, the actor is also an extremely important part. Wang Yuxi expressed that when choosing characters, he will pay more attention to the actors' acting skills.

Because the traditional television dramas and movies cut the lens to pieces, it can end in two or three seconds with one lens. It can take up to fifty seconds without long shots. Therefore, in the traditional filming, the director sees the actor performing for three seconds. As long as the performance in the three seconds is very good, it does not require a long-time performance.

VR panorama shots increase the actor's performance difficulty, because the shot editing will not be so broken, so I hope the actor can be played in one breath. And drama actor, or stage actor would be more suitable. " They belong to the live show, there is no NG, the performance skills are more suitable for VR shooting ."

VR shooting is a problem that the director himself needs to solve, and how the audience gets a high-quality VR viewing experience is an essential platform. At present, three traditional video platforms led by LeTV, iQiyi, and Youku have successively released specialized VR platforms, which seem to naturally assume the task of popularizing VR to the general public. Just as LeTV previously planned at the conference, some of the stars behind the scenes, concerts, as well as self-produced dramas were released. However, these VR content traffic is not ideal compared to the traditional programs on the platform. Wang Yuxi talked about the reasons behind it from the platform side.

First of all, the sense of experience is not good enough.

Cheap carton glasses do not fully exhibit the characteristics of VR. The experience of the three big heads is now good, but it is expensive. "Until the beginning of this year, people still doubted that the VR experience would be able to do a good job. Now no one has doubted it. The suspicion is price."

Second, good content is a must.

As for how to define "good," he said that VR is about immersiveness. If it is a VR shoot, "As long as the picture is good enough, I will really feel where I am shooting and interact with the subject." VR It will also make you feel real, not like the game, it needs real shot to achieve, and this is technically much more difficult.

"In the 2D VR panoramic video, if I was in a church and looked up to the dome, all the murals were on the wall. They wouldn't come up, but once I shot 3D VR, the murals on the wall It will come to life, and other characters like angels will be three-dimensional. This is a completely different experience."

The last is about the platform itself.

Lei Fengwang editors heard that many directors reluctantly stated that even if the VR works are currently shot at 4K, 8K or VR sound, the existing platforms cannot support it. Wang Yuxi thinks this has to be attributed to infrastructure and hardware issues.

“It's like the principle of barrels. The final audience sees an image that depends on the shortest board in the bucket. It may be the speed of the network transmission. It may be the audience’s mobile phone, or the source, or the platform’s playback. ability."

He thinks it is now stuck on hardware, which also includes network transmission. "Our base station construction has not yet reached 5G, 4G, I think the screen resolution up to 4K, 4K sometimes quite a card, 2K will not card." In addition, the audience's mobile phone can support 4K screen is not much.

Perhaps these are the problems facing the entire industry.

Not long ago, Nokia returned to public view with the panoramic camera OZO and announced cooperation with LeTV. Wang Yuxi disclosed that the two sides cooperate in many ways. Nokia provides OZO technical support for LeTV and enjoys Nokia as a broadcast channel. Both parties will jointly develop some VR shooting processes. He also stated that some patent applications related to VR shooting are currently under way. “We are open and willing to cooperate with other people, but we still need to master key technologies.” He also told Lei Feng, LeTV VR hands many projects in progress, the recent VR version of “Ching Ming River map” published on the platform, not Knowing the story of Yu Liang can attract audiences.
