"Movie shooting against the backdrop of the huge LED", I saw the next generation studio of Netflix

Netflix has strengthened its production base in Japan to support the creation of works by domestic creators.Accelerate virtual production shooting, such as renting two studios in the Toho Studio, the largest shooting studio in Japan, for multiple years, and using a huge LED screen as a background at the time of shooting.The technology was released to the media and stakeholders on the 13th.

Virtual production is to solve problems in directing and shooting using advanced digital technology.It is collectively referred to shooting techniques such as world capture, visualization, performance capture, Simaru, interactive writing, and in -camera VFX.

Attention is "Inca VFX" in this.In previous movies, etc., actors and others were shot against the backdrop of green back.After shooting, the background of CG is synthesized in the work process called post production.He also performed color grading and completed the video.

In -camera VFX is installed like a wall with many displays such as LEDs.It displays videos of overseas streets, nature scenery, fictional world landscape drawn with 3DCG, and SF spaceships.Before that, it is a technique to bring actors and take pictures with the background of LED.It is named "Inca VFX" because the final "visual effect" is obtained in the camera during the shooting.

There are multiple advantages of the in -camera VFX compared to the synthesis after greenback shooting.For example, since the light of LEDs and on -site lighting corresponds to the art sets such as cars, motorcycles, grass and tents installed in actors and studios, reflections on natural objects, as in reality, are obtained.You can shoot including.

In addition, as long as the video for the background can be taken, it can be photographed in places where it is usually difficult to shoot by chartering the location, such as the parliamentary hall or a highway.In reality, it is a place where it is difficult to occupy for a long time, and it can be used for applications such as shooting slowly.

It is not affected by the weather or time because it is taken indoors."I want to take a picture of the sunset scene so I wait until the sunset" or "I couldn't shoot the ideal cut during the sunset hours, and it was just night", so I took the sunset many times in the background.Can.

There are also advantages when a car is installed in the studio and displays the cityscape that flows behind it and shoots.If you shoot outside in reality, you will have to run the same course many times until you can take a satisfactory cut, and if the shooting fails, you have to return to the first point again, but if it is the background of the LED display, loop the background video.Then you can easily shoot as many times as you want, and you can take many take and cuts.

Also, in the green back, the actors must perform while imagining "what background is being synthesized now" until the background video is synthesized, but if it is a LED display background, while understanding the situation.Acting is possible.For example, in the scene of driving a car, it is possible to perform natural performances such as "the background road is curved, so turn the steering wheel accordingly", creating more realistic images.

In addition, Digital Frontier, who uses Unreal Engine to make games and movie background CGs, cooperates.The 3DCG video generated in real time can be displayed as the background of the LED display, for example, pursuing an ideal camera angle, changing the shooting lens to a telephone -closer one on the way, and changing the depiction of the background CG according to it.Flexible response is possible.

In addition, if you shoot an actor in the background of the "sunrise from the day of the wilderness from the day of the wilderness" drawn in 3DCG, you can shoot a video of a time -lapse shooting over a day in a short time.It can also be used for challenging such new expressions.Although it is a detailed point, there is also an advantage that it looks natural on the LED display, such as the "gap between a tree branch and branches", but it looks natural on the LED display.

Shunsuke Ito, a special film, who is also involved in shooting such as "Naked Director 2", explained the benefits of these in -camera VFX with demonstrations.It can be taken while checking the "finished picture", which will reduce post -production work.

Although the in -camera VFX has a wealth of possibilities, on the other hand, the use of shooting sites has just begun, and there is also a need to accumulate know -how.As an example, Mr. Ito is a problem, such as how many mm lenses should be taken with lenses when shooting the background video to be flushed in a live -action photo, and it is better to shoot all natural ball images in high resolution.And if the buildings and humans reflected in the background look unnaturally large, how to correct them, or how to separate the subjects of actors and cars and LEDs to see how to make a more when shooting closer to the LED display itself.The scenery of the LED is narrower than the real landscape, and it tends to lose data such as white jumps, so it is necessary to fine -tune it on site when shooting with a cinema camera.

In addition, the LED display in the background can display 1,500 nits as brightness, but if it is displayed too brightly, the "black floating" will be noticeable, so it is better to display a video of about 250 to 300 nits.The light emitted from each LED does not reach that much compared to the dedicated lighting, so it is important to use the lighting together as a technique.

Installed tents, lanterns, rocks and trees in the studio.In shooting that displays the 3DCG of nature in the background, it is important to make the highlights of the background and the "good connection" of the highlights of the accessories and the actors in front of them."For example, you can overcome the idea of putting buildings and rocks at the border and separated, and you can use the traditional method of shooting from the back to the front," he said.
