Vr film production skills, Google vr film producer told the answer

Brillhart introduced her experience in helping people create high-quality vr content at the EmTech MIT 2016 conference in Cambridge, Massachusetts on Wednesday. These high-quality vr content is a 360-degree video made by consumers using smartphones and portable vr helmets. .

Vr content production is an area of ​​great interest to Google. Google’s YouTube has supported 360-degree video since last year. Recently, it launched a mobile vr platform called Daydream and a matching vr helmet and smartphone.

In order to encourage consumers to buy Google's vr devices and use the YouTube platform, Google must come up with more quality vr content. Brillhart's role is to help people make vr films and share the wealth of experience she has accumulated over the past year and a half.

Brillhart said: "There is no fixed model for making vr films, so the concept should be forward-looking. I will first express my ideas for discussion."

Brillhart has an important finding that the traditional storyline does not apply to vr films. A 360-degree vr movie is actually not a story, but a combination of multiple stories. She explained that this is because the story can be viewed from many different perspectives.

If you ignore this basic feature of the vr film, then the film made by the filmmaker will make the audience feel puzzled, let alone experience the unique enjoyment of the new technology vr.

When Brillhart made the vr film, she focused her attention on shooting a series of 360-degree motion shots or "dynamic worlds" instead of static movie frame images. In post-production, she wondered how the audience would interact with each dynamic world, but managed to present a dynamic shot in a seemingly coherent way.

Brillhart came up with this method when she made her first vr film, World Tour, last year. She started doing some regular frame image editing work, but soon found that the film was too rough, especially when watching through the vr helmet, so she understood that the traditional film production method would not work.

One night, her mood was a little low, and she accidentally looked up and saw the light bulb on the ceiling, so she began to draw circles. She draws the rendering of the film in the form of a chart. The circles represent the different worlds in the film, and the black and white dots are where the audience is most likely to enter and exit each world.

The video game industry is more familiar with this skill than the film production industry. Brillhart said: "Game designers know that they need to create a potential story experience center, rather than a one-on-one story. They come up with a big idea and provide players with tools and tools. Means to let players discover their own stories."

The work of architects is similar, in fact, they are in the design of various spaces for dialogue with people. Therefore, Brillhart said: "When making vr films, producers can learn from game designers and architects."

Step 1 of VR film production; have a shooting device. VR video is a 360-degree camera, so you need a four- or full-range camera with multi-directional cameras such as the Google YI JUMP VR camera, Jaunt ONE VR camera, and Nokia OZO panoramic camera. Since the camera lens is fixed focus, there is no close-up lens and walking shift in the traditional movie, so it is necessary to set the movement track of the camera in advance, which is the basis for deciding whether to take good quality VR video.

Shooting video for VR devices is not an easy task. VR's 3D environment requires video capture devices to shoot in 360-degree range, so choosing the right panoramic video capture tool is a top priority for producers. NextVR launched the world's first VR 3D digital cinema camera system in 2014 with six Red Epic Dragon cameras. GoPro also produced a 16-camera array for shooting VR movies. These are professional grades, but there are also Ricoh's launch of theta full celestial camera for the average user to shoot non-professional VR video for the home user. It is achieved by 360 lens shooting through the front and rear of the fisheye lens.

VR movies give viewers an opportunity to interact. The audience can explore the shooting environment on their own. In this case, your position is a big problem. Finding the right audience to watch the position, moving the track, etc. Different, even traditional, composition methods are no longer suitable for VR movies.

Step 2 of VR film production; fully enclosed shooting environment. In order to provide a more realistic shooting environment, the environment in which the camera is located cannot appear people or things that are not related to the video. Even the director should stay away from the shooting scene or perform proper camouflage to avoid wearing it. Therefore, the video shooting scene is very important. Of course, not all closed environments are suitable for VR video. Only those backgrounds with strong sense of substitution will give VR users a sense of immersion, which will show the beauty of VR video, such as "Star Wars" and "Pirates of Dreams". This movie background is very suitable for VR video shooting.

VR film production step three; VR video post-production is very critical. Since the splicing of VR video affects the look and feel of the video, it is necessary to make a rehearsal beforehand before shooting, and it is best to pass it once when shooting. In addition, consumers will take the initiative to find the scene when they watch it. Therefore, in the video production, some scenes should be set to guide the interaction or the video production will add subtitles next to the character being spoken, and correctly guide the audience to follow up the story development.
