What is virtual production
Until now, shooting using a green background has been carried out, but post-production compositing with 3DCG was common after shooting.
However, in recent years, various processing has become possible in real time, so shooting in which chroma key synthesis is performed in real time at the same time as shooting, called virtual production, combined with a camera tracking system.
It is now used not only in commercials, but also in Hollywood movies, NetFrix dramas, and taiga dramas due to advantages such as being able to shoot while checking images by anyone involved, including the performers, and being able to shoot indoors, not limited by time zone or weather.
camera tracking system
In virtual production, when synthesizing CG in real time, CG rendering is performed according to camera work, so it is important to acquire camera position information and acquire camera lens information.
Each company sells camera tracking systems using various methods, such as tracking systems using infrared cameras and markers attached to cameras, and camera tracking systems using characteristic points.
Shooting using a green background
In virtual production shooting using a green background, chroma key processing is performed in real time and synthesis is performed.
The feature is that you can shoot as if you were in a space rendered with 3DCG, but there are also restrictions such as the need to apply the light flat for chroma key processing.
IncameraVFX
It is a virtual production shooting method that uses an LED display as the background, and chroma key processing is unnecessary, and since there is self-luminescence from the LED, it is possible to shoot without failure even when shooting with transmission or reflection of glass, etc.
On the other hand, there are problems such as the sense of distance between the camera and the LED display, where a large LED display is required for camera work or wide-angle shooting, but it is extremely expensive.
Differences from previous shooting methods
The process for virtual production is very different, especially from traditional shooting methods.
Until now, synthesis was performed after shooting, so CG processing, such as modifying the 3D model after shooting, was common after shooting, but in virtual production, synthesis is performed at the same time as shooting, so it is necessary to set up 3D assets beforehand. In the case of shooting with an LED display, there are also many items that need to be adjusted before shooting, such as LED color and CG color, brightness and color adjustments, etc., and prior adjustments are essential for high-quality motion photography.
What Kadinche can do
Shooting using a green background
Virtual production shooting using a green background is possible in an area of about 4 m x 8 m.
RedSpy is used for the camera tracking system, and Pixotope's PixotopeGraphics is used for synthesis, and chroma key synthesis and post-processing are also possible.
IncameraVFX
There is a 4m x 2m 1.6mm pitch LED display, and InCameraVFX shooting is possible.
Similar to the green background, Pixotope is used for projection onto the LED. It is also compatible with full color lighting with NanLite, and shooting in conjunction with DMX is also possible.
Set up the model
We are also setting up 3DCG assets to be used as backgrounds.
