How do you do your movements from the stars?

Simply put, it is behind-the-scenes production and computer synthesis technology.

Good times:

One:

The basic principle is that a one-second TV picture consists of 25 frames, that is, 25 continuous freeze-frame pictures, which makes use of the phenomenon of human visual persistence. Before shooting, the protagonist

Located in the center of the camera array, all the cameras are arranged according to certain rules, and the unified focal length, appropriate focus, aperture, shutter speed and other parameters are adjusted in advance, and then at a specific time, according to the needs of the director, first,

From one machine to the last, the exposure starts in turn, and each machine will get a freeze-frame picture, that is, one frame, one fifth of a second. Calculate, the freeze-frame images obtained by 60 machines add up to form a closure.

A 2.5-second shot.

In the play, the director used a time-lapse high-speed camera, whose main advantage is that it can shoot from multiple angles. When the figure is still, 46 cameras shoot at the same time. Then, after the characters are eliminated, the background is reassembled in the framing mode. , the multi-angle pictures are segmented and then combined with the background.

In the rotating image, another camera will also be photographed, which will be erased by post-production. Fairy mountain calls for animals to save children, and almost falls into the sea in this way. The designer of BS ART-TECH said that the time slicing technology of You from the Stars is a brand-new attempt.

Two:

Gianna Jun's beauty in the play is amazing, and the picture is also beautiful, which can be described as high-end atmosphere! It is estimated that many photographers are curious about whether multiple reflectors are used in the shooting process. However, according to South Korea's Daily Sports, only 2-3 reflectors were used in the play.

Analysis on the combination of reflector and later color matching

According to Jin Genxiu, the lighting director of You from the Stars, only two or three reflectors were used when shooting Gianna Jun, which is no different from the heroine shooting ordinary TV series. On the contrary, when highlighting the image of Gianna Jun,

Relying on lighting technology. In order to get a true and natural picture aesthetic feeling, both indoor lighting facilities and outdoor lighting facilities are used in the shooting. In this way, the already beautiful Gianna Jun is even more beautiful.

Eyes.

Three:

Do you know why the scenes and costumes in You from the Stars match so well? This dream country is actually a visual feast of CG technology. This is the so-called scene special effects.

Professor Du in the play is as rich as an enemy. This rich country has appeared in many places: focusing on real estate speculation for 400 years, half of the land in Seoul is owned by it, and any bowl in the house is antique. So it's called beast, full name goddess.

High-rise residential buildings must be a great attraction. When we see the night view outside the balcony, are we surprised that Korea is a beautiful city? In fact, this night scene is made of special effects.

Night view of balcony realized by special effects

Both the blue screen and the green screen are background screens for shooting special effects shots. Actors perform in front of blue and green screens and are photographed by cameras. The picture is processed in the computer, and the blue or green background is removed and replaced with other backgrounds.

Blue screen and green screen keying technology are the most commonly used synthesis technologies in the film and television industry. Their purpose is to overcome the limitations of specific scenes and improve the flexibility of shooting. Finally, in the later stage, the blue screen or green screen is removed, and the virtual scene is synthesized to create a very realistic picture.
