Today's VR is hailed as the future of Hollywood entertainment because it makes science fiction a reality. After the outbreak in 2016, VR technology penetrated into many places like water, such as games, online video entertainment, live broadcasting, medical treatment, education, and military affairs. Movie and TV entertainment was one of them. High expectations. Last year, well-known directors such as Zhang Yimou and Gao Qunshu also announced that they wanted to shoot VR movies. This gave VR movies a lot of attention.
How can VR film and television completely immerse users?
The appearance of VR film and television has also been accompanied with more new problems. For example, how to tell a story, how to write a script, how to handle scene and sound switching, how to hide a director's camera, how to cut a 360-degree scene, how to measure it, how to control it, Performing sensory stimulation? The most appealing aspect of VR is that this technology can give users an immersive and immersive experience, so after all, immersing VR movies is the most important consideration for VR directors.
The immersion of the user comes from where it is needed. This requires the VR director to serialize clues in the movie to maintain the user's continuous experience. Those with VR experiences said: "When watching VR movies, we always see some directional images to guide my vision. There is no sense of immersion. This experience is really terrible." , guiding the user's line of sight while maintaining the user's continuous experience has become a very difficult task.
Panorama sound or will become an important breakthrough in VR film and television
In order to create a immersive sense of reality, VR video vendors are eager to improve key technical parameters such as refresh rate, head tracking delay, field of view angle, resolution, etc. However, among these parameters, the only one missing is audio, and we can imagine panoramic sound pair VR. The importance of virtual reality.
The loss of panoramic sound can be said to be the VR film and television practitioners, and before the CES sound digital technology at the CES, provided a complete set of panoramic sound collection solutions for VR video shooting, including VR audio machine Sound Pano and professional VR Scenes Studio Pro, an audio post-editing editor, solves the VR director's pain in the acquisition of panoramic sound. It is reported that Sound Pano is a customized panoramic sound acquisition device developed for VR director, designed to help the director solve the problems faced in the shooting, such as asymmetric sound and picture, Tibetan wheat, and special pointing microphones.
Sound Pano retains its head structure and facial features. With natural HRTF acquisition, it can simultaneously record 16 tracks in 8 directions and achieve a 48Khz sampling rate of 24bit professional lossless data collection. It can accurately capture the position, distance, and trajectory of the sound source. Restoring and recording the current real sound field relationship is in stark contrast to the unreality brought about by the later synthesis or simulation of audio in VR movies. At the same time, the audio files recorded and output by Sound Pano can realize 8 tracks merge and split without affecting other track information, and they do not need special software for editing. It can use the existing non-editing post-production software.
Considering that in the later period, the director needs to add some other sound effects, such as talking with aliens, dinosaurs, etc., and at the same time guaranteeing the movement of azimuth and distance to achieve the effect of panoramic sound, so Mori has independently developed a professional VR audio later stage. Editor - Scenes Studio Pro. The editor provides a complete solution for post-production of VR audio. It can not only edit the sound produced by Sound Pano, but also can be used alone. When editing an audio file separately, it is based on three-dimensional coordinate modeling to set fixed-point coordinates or movement trajectories individually to achieve a panoramic sound effect. According to the person in charge of Mori's sound technology department, “Studio Pro is equivalent to a panoramic sound simulation editor when used alone. It sets the parameters of the corresponding scene to simulate sound field relationships such as conference rooms, studios, outdoor environments, etc. For direct use, these parameters are also open to the outside world. The VR director can also modify the parameters to achieve the sound field he wants to achieve.â€
“From the appearance point of view, it is a cylinder, and I never thought that it would solve my troubles for a long time (VR video shooting) sound recording problems. The sound VR shooting program given by Morinaga, with this Sound Pano recording of panoramic sound, can also be very good Hidden.†The director of VR Film and Television said after using the sound recording of Mori Sound Pano on the spot, “What surprises me is that you can also use the panoramic sound to guide the audience to watch according to the story. The viewers in VR film and television are relatively free, in a gun battle, If the sound is panoramic, then the spectators can hear the sound of gunfire from far to near, and can hear the right person retreat to the protagonist.The spectators will not be confused when they look around and only see the protagonist's back. , I can't understand the plot, it's just amazing!"
Recalling the development of the Chinese VR film and television market in 2016, although it is actually less than expected, neither the user acceptance nor the number of users and contents are steadily increasing. As a film and television industry with extremely strong entertainment attributes, the development of VR film and television has been integrated with the sound of panoramic views. It is believed that in the future there will inevitably be VR film and television works that subvert people's imagination.
Residual Current Circuit Breaker
RCCB named Residual Current Circuit Breaker. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, Residual current circuit breaker/RCCB(without over-current protection) will cut off the power rapidly to protect human safety and prevent the accident due to the current leakage. The rccb switch which made from Korlen electric can be used as infrequent changeover of the line in normal situation.
Korlen electric ---- the rccb switch manufacturer,produces types of Residual Current Circuit Breaker. It is applicable to industrial site, commercial site, tall building and civil house.
