On August 17th, the Wormhole VR team under the Legal Evening News held a small VR video exchange seminar. The reason for the smallness is that there are only two invited guests, namely Dong Yuhui of UpanoVR (Zhitu Technology) and Zhuang Jishun of Lanting Digital, but “small†is not so appropriate, because the rectangular large conference room is full of seats and stands still. audience.
In April of this year, director Dong Yuhui participated in the shooting of the VR version of "The Love of the Millennial Mountains." This film attracted a lot of attention because of Huang Xiaoming's participation. He also summed up the "pits encountered by those VR cameras" from the past. .
On-site guests answered questions
Once those pitsFirst of all, the equipment is unstable. Two years ago, he went to Malaysia to shoot a field record inspired by Bell's Wilderness Escape series. There is a giant lizard in the area, which can be up to 30 or 40 meters in length. At that time, they took the GoPro machine and went to the island of Tiga to use raw meat as a bait and put it under the camera. In this way, more than thirty giant lizards ranging from thirty to forty meters in length were captured. If they were successful, they would be good VR documentaries. Unfortunately, the GoPro's battery life is very short and can only last for about twenty minutes. It often crashes in extreme environments such as high temperatures. They want to shoot again and can no longer restart.
Second, depth of field and focus issues. They tried to use a whole range of full-frame SLRs to make panoramic solutions. Its advantage is good picture quality, but the problem is that the depth of field is too shallow. The solution is to open the aperture to a minimum, try to use a large depth of field to shoot the full real picture, but this will have very high requirements for lighting.
However, for the director, the most painful thing about VR shooting is not monitoring in real time. When shooting with multiple cameras, only multiple monitors can be used for monitoring. In the face of a lot of material with severe distortion, the director is basically blind. So they used two years to develop an integrated VR camera, developed their own motherboard and real-time splicing chips, hoping to accumulate experience in the past VR shooting, so that latecomers can learn from.

Speaking of "Everything is always love," Dong Yuhui said that full preparation is more important than shooting itself, and Zhuang Jishun is very much in agreement. Different schemes will be designed for shooting because they cannot be “freshâ€. He explained that he has tried many programs. For example, if you want high quality, the aperture must be set to a minimum, and the lighting requirements on the scene are very high.
The viewers of the "Everything Loves Everywhere" will follow Huang Xiaoming to Shanghai in 1925. They can only go to the movie studio. The movie studio pays according to the time. Others only need to pay for money in one location, but for VR, they have to put the whole thing together. Street to rent. VR film and television art set and props are more important than traditional film and television, must be carefully prepared.
He also mentioned that the actor's scheduling problem is very difficult. Because you want to present a panoramic view of the beach, but the beach is very large, you need a lot of actors, 500 group performances are not much. VR shooting time is very short, but the preparation time is very long, every time you cut a shot, the audience needs to react 5 seconds. Long shots also have requirements for actors, and numerous rehearsals are required before shooting. The position of many extras must be very precise, which requires a long time rehearsal.
As mentioned above, real-time monitoring is a big problem. They used Google's Odyssey system that was stitched with 17 GoPros. They also used a very earthy method to monitor them. Each camera was connected to an iPhone and it was very painful to encounter line problems.
Good experience sharingRecently, the director Dong Yuhui took a team to Tibet and Cambodia for shooting. The scene also shared some experiences.
First, the scene must be extreme. There are no montages, visions, and mid-range concepts in VR video, but all are presented to the audience. When watching, the audience is easily visually fatigued, so the scene is very important. It must be visually pleasing and it is best to pick up the scenery that is not commonly seen by the audience.
Second, the role of interaction must be clearly designed. What kind of role do we have to design for the audience? Who does it interact with? In the past, someone used a third-person perspective, two people played, and a third person watched. Then the audience still stayed away. This was no different from traditional film and television and there was no sense of substitution. While some foreign teams design more of the first perspective, the audience is the protagonist and the audience is the camera.
Third, pay attention to the guidance of sight. 360° videos are not all valid information. Many viewers are confused when they first watch VR videos: Where should I look? The methods of the directors are guided by sound, and now many VR helmets and platforms support 360° sound field. Of course you can also guide your eyes through moving objects such as butterflies and puppies.
Fourth, you need to pay attention to the distance and height of shooting. How do we show the intimacy of the audience and protagonists in VR film and television? For example, we are in touch with the female goddess of the goddess level. If she is particularly far away from us, then she will not feel it. If it is only ten centimeters? Through some tests, they found that a lot of people close to the goddess will blush.
He also said that the height of the camera is also laid out. Although some people say that VR has no composition, the composition in VR is shown by other methods. From the height of the camera, to simulate a person's normal vision, you need to consider whether the audience is standing or sitting. How height and environment cooperate, to be accurate to centimeters, only to shoot it out and experience will be good.
At this event, Zhuang Jishun also made a share, but similar to other activities, see the article “Say Good VR Technology to Tell a Story, but You Tell Me This Is a Pitâ€.
