The Use and Development of Digital Technology in Film Acting Essay

Application and Development of Digital Technology in Film Performance

Introduction

Driven by the Industrial Revolution and the development of science and technology, the revolution in film technology manager of the three major changes, changing the audience's traditional mode of appreciation at the same time, but also stimulate the film creator's artistic creativity thinking. The arrival of the digital technology era, but also a direct change in the traditional mode of film production, it can be said that the film is in a new digital film era, the birth of digital cinema marks the most radical change in the film industry. 2002, the film "Simone" tells the story of an actor uneasy, that is, the invention of the virtual actor coding program, the entire film production as long as there is a director to manipulate can be, while the actor's performances are replaced by computerized actors. So will this era of digital-controlled movie acting become a reality?

I, the important role of digital technology in movie performance

The role of digital technology in movie performance is mainly reflected in the following two aspects. On the one hand, it is constantly strengthened to the performer's performance style. In movie performance, the application of digital technology can continue to expand the narrative space of the movie, and diversified film subjects also provide a broader play space for digital technology. Fairy tales, magic and more unknown worlds can be realized with the help of digital technology by the filmmakers' ideas and conceptions, and some captured performances are virtual and different from daily life. This requires performers to give full play to their acting imagination, and even to boldly subvert traditional aesthetic principles in order to create a movie character that meets the audience's aesthetic needs.

On the other hand, digital technology can improve the artistic expression of films and promote the professional development of performers. An actor who has not received professional training cannot perform in front of a blue screen because he simply cannot imagine what it is like behind it. Although many directors in the selection of actors, mainly to the actor's temperament and image as the standard, uphold the plasticity of the work, and these actors without professional training, although to a large extent very good to complete the entire actor to create, but in the face of digital special effects, the actor will not be able to cope with the full. At the same time, the traditional movie performance, the actor is completed in the real scene, it is easier to play their own emotions, but in the digital technology, with the virtual scene, it is difficult for actors to find emotional support, the quality of their performances put forward higher requirements. All these show that although there are higher requirements for actors' professionalism under the promotion of digital technology, on the other hand, it can also well promote the professional development of actors. It is an undeniable fact that movie performances driven by new technologies require more specialized actors.

The practical application of digital technology in film performance

1. Digital technology applied to film space performance

The biggest difference between film and television is that film can be a very good performance of the film space, the film can be a very good performance at different times and places. The audience can have an understanding of any place and space on earth through the movie performance, and can follow the creativity of the director's sky, and the digital technology will expand this time and space advantage of the movie. In the film Gone with the Wind, the director reshapes space through the use of multiple exposures, and the impact is the freedom to change the spatial environment of the screen many times through the use of this technology. Traditional film performances are difficult to capture some moments and details directly on the screen, but with the help of digital special effects technology can be captured on different screens after the synthesis of various elements to produce a very visually stunning picture effect, which is an important feature of digital special effects technology.

In the classic movie Titanic, the scene where the hero and heroine embrace each other on the boat with their arms spread out, and the sea water and the sea breeze meet and merge has become a timeless image of the movie, thanks in large part to digital technology. I believe that no one will shoot a movie to deliberately cast a huge ship like this, coupled with the surrounding lights, blue screen and other false models, are relying on digital technology will be a combination of various elements in a picture, so that the environment and the role of the real fusion together. The application of digital technology in the movie space has brought higher expressiveness to the development of movies, and also put forward higher requirements for the actors' performing art. The more complex the space synthesized and virtually generated, the more dependent on the actor's performance creation.

2. Digital technology used in film cloning

The main form of human cloning on the movie screen is the twins, although the existence of real twins, but many times with the help of film technology to complete. Initially technology with the help of multiple exposure technology for the original synthesis, and manual operation of the screen division, but this technology to produce a clone of the image of most of the fixed. And the application of digital technology in the movie cloning, a good solution to this problem, the clone image in the movie and the reality of no difference, can carry out free communication and movement. The movie "Clone" is the application of digital technology in the movie cloning in the best embodiment of the director of the film in the United States television interviews, said that the movie fooled 90% of the audience is no problem.3. Digital technology applied to virtual images virtual image is generated with the help of digital software on a computer workstation directly generated by a kind of image, generated without the need for a camera to shoot, and can be output directly on the film. The application of digital technology in the virtual impact, can be a good combination of performers and virtual impact, so that the actor's performance is in the actor and the virtual impact of the combination of the character image shaped after the actor, rather than just a simple performance of the actor. The 'main embodiment' of the application of digital technology to virtual imagery is found in Terminator 2. The audience in the screen to see the future killer in the effortless under the time to cross the iron bars, had to marvel at digital technology will be the virtual image and real people can be in the naked eye can not distinguish the basis of the perfect combination.

One of the most important applications of digital technology in film performance is digital compositing, which is the technical process of synthesizing two or more source images into a single image. In order to maximize the effect of synthesis, technicians should design shapes of non-existent creatures on the computer to find the texture of the object that matches the director's needs, and create the corresponding movement trajectory for it. Once the virtual image designed by the director can move freely according to the director's intention, the virtual image and the actor's real behavior and expression can be integrated together. At the same time, in order to fully express the actor's expression and behavior, such as capturing the actor's smile when the form of muscle movement, can be in the actor's face to paste some light-sensitive metal sheet to improve the performance effect.

The development path of digital technology in movie performance

Digital technology, as a kind of advanced technology for movie production, includes digital image synthesis technology, digital image processing technology and computerized image production technology.

The application of digital technology in film performance can use the computer's virtual simulation, three-dimensional dynamics and synthesis technology to compose the image, using digital technology on the computer to build the photography, scenes, editing and other content. The development path in digital technology movie performance is reflected in the following points.

1. Reconstruction of film space-time

The famous writer Goethe once said, "The highest task of any kind of art is to use illusion to produce a higher and more real illusion." The greatest charm of the movie is that it can bring human beings into more unknowns, and digital technology provides a link to such more unknowns. The use of digital technology to advance the art of film performance can be accomplished by reconfiguring film time and space. The reconfiguration of film performance space-time under digital technology is accomplished through the following method, i.e., the transformation of the authenticity of the core of the traditional image ontology under the role of virtual images. Although the movie performance under digital technology retains the authenticity of traditional movie performance art, this authenticity has already exceeded the authenticity of traditional movies and risen to a higher realm, i.e., hyper-authenticity.

By reconfiguring the time and space of the movie, the creative thinking of the movie creators has been dispersed to a large extent, leading the audience to a completely new world of movie watching. However, digital technology-driven movie performances put forward higher requirements for actors, which not only require actors to have rich imagination, but also require them to give full play to their philosophical thinking to better create their roles. Although, the movie time and space reconstruction in China's film industry has not been fully formed, but I believe that in the near future, this trend will become the main direction of the development of China's film performing arts.

2. Improve the actor's physical performance

One of the most important technologies in digital special effects technology is motion capture technology, which requires a high level of physical performance from actors. Therefore, to improve the actor's physical performance is the main means of the development of movie performing arts under digital technology. For example, Andy Sekis, the performer of Gollum in The Lord of the Rings, injects soul into the character in a special way, and is the representative actor of motion capture technology, who crawls on all fours from time to time and walks upright from time to time in the movie performance, and well interprets a small monster with eccentric character. For example, the main character Hulk in "Hulk" is director Ang Lee himself cloaked. When director Zhang Jianya was shooting the new version of the movie "The Greatest Hulk", he invited Six Little Boy to participate in the movie, but when he learned that he was just a digital prop, he didn't agree to do so. However, when Liu Xiaolingtong learned that he was just a digital prop, he didn't agree. In this digital technology-driven movie, all the director needed was the "monkey" form of Liu Xiaolingtong. This shows the importance of the actor's physical presence in a digital movie.

In the movie "Desaike Bale", the boar in the film, even with digital special effects technology, but the animal is not controlled, can not be a real shot on the scene, there can only be a professional martial arts actor using motion capture technology, and after the later digital technology synthesis and get. Of course, on the other hand, the birth of digital special effects technology, stuntmen will be a great challenge, but also may be the main opportunity for professional actors. In a word, the movie performance driven by digital technology puts forward higher requirements for actors, and requires the quality of actors to be professional and comprehensive.

3. Realize the diversified innovation of character image

The blue aliens in the movie Avatar give people an extraordinarily deep impression, largely because of the reflective ball. The reflective balls that shine on the performers are an important form of digital technology expression, namely expression capture and the motion capture technology mentioned above.

Expression capture technology utilizes performance data from the muscles of an actor's face to show virtual character expressions, and is visually depicted by the actor's clothing and the sensor points on his or her clothing. In the shooting, can use digital equipment including digital video cameras and cameras, including multi-directional on the actor's body in different positions reflecting the ball movement trajectory to record, and then in the computer after the synthesis, to produce a dynamic character image, shaping a new movie performance role image. Who Framed Roger Rabbit" is a milestone in the development of digital cinema, with only three live actors in the entire film, bringing "keying technology", a digital imaging technique, to the audience's eyes. Keying technology is the use of blue or green curtains to build a studio background, and then use the reflective ball on the digital keying, the use of digital technology to set up a real shooting scene, and ultimately built into a complete movie display space.

In the Japanese film industry, computer graphics were used to create one of the world's first "computerized moving pictures" that resembled a real person. The world's entire movie is a digital actor's movie has appeared, "Final Fantasy" in all the characters are computer production completed, the specific method is as follows: the real actor's expression and movement into the computer, the use of the computer to create a realistic digital character model, and with the help of the impact of the capture technology successfully shaped a "statement of reality" character image. The main character in "Forrest Gump" is a character with a "declared realism". Forrest Gump" in the protagonist and the deceased overall meeting scene in-depth, Lt. Dan Teng in mid-air broken leg shocking, but very real, its credit is the digital technology in the local keying technology. Local keying technology in addition to focusing on local keying boundary points, but also to allow actors to create the role.

In short, the new technology to promote the film performance is in a period of rapid change, digital technology in the development of film performing arts plays an important role in promoting. Digital technology in film space performance, film cloning and virtual image synthesis have good application, and in order to higher improve the role of digital technology in film performance, can be achieved by reconstructing the film space-time, improve the physical expression of the actors, and realize the diversified innovation of the role image.
