Many movies are released during the Spring Festival. In addition to choosing movies, the different theaters are also dazzling, such as IMAX hall, Dolby Atmos hall, CINITY hall, CGS China giant screen hall, etc. What do these terms represent, and they are different from traditional movie theaters. What is the difference compared to the hall?
It is not appropriate to choose these types of seats
When buying tickets for a movie, if you want to choose the viewing position with the best audio-visual effect, you don’t just choose the middle position. Instead, you need to combine the movie type, theater specifications, screen size, step angle, screen Various factors such as angles and viewing needs are comprehensively considered.
For 2D movies, according to the optimal viewing position guidelines announced by the American Society of Motion Picture and Television Engineers, first of all, the picture needs to occupy the audience's field of view as much as possible, and the angle of sight between the audience and both sides of the screen must be at least ≥36°.
Secondly, in order to avoid cervical spine fatigue, the elevation angle between the audience and the screen horizontal line should not exceed 35°.
Based on these two principles, seats on either side of the screen with too small a horizontal angle, seats in the front row with an excessive elevation angle, seats in the back row that are too far away from the screen and too close to the rear speakers will all affect our viewing experience. The audio-visual effect experience is better, so if you want to get a better movie-watching experience, it is not advisable to choose these types of seats.
Considering the comprehensive audio-visual effect, if it is a small hall in rows 8-14, it is best to choose the front, back and center positions of rows 5 and 6; if it is a middle hall in rows 15-20, it is best to choose the front, back and center positions of rows 7 and 8; If it is a hall in rows 21-25 or an IMAX hall, it is best to choose the center position in front of and behind rows 9 and 10.
If you are watching a 3D movie, since 3D glasses will weaken the screen brightness by about 40%, for better visual effects, you should sit 1/2 from the screen to the projection window.
The different ticket prices at different locations in the same screening room in the cinema are also priced based on the viewing effect. However, since everyone's viewing needs are different, the specific choice must be made based on their own needs.
What are the differences between different theaters?
Many friends have noticed that movie ticket prices are closely related to the type of screening hall. So, what is the difference between IMAX halls, CINITY halls, Dolby Atmos halls, etc. and traditional theaters?
Movies are an audio-visual art that combines sound and light technology. The projection effect of a movie is determined by the projection system and sound reproduction system of the theater.
The playback quality of the projection system is closely related to the screen and projector. Traditional digital projections mostly use screens of ordinary specifications, using low-brightness xenon lamps as light sources. The resolution (which affects the clarity of the picture and is positively related to the clarity of the picture) can reach 2K. , the frame rate (the number of picture frames refreshed per second, the higher the value, the more coherent the visual effect, the clearer the picture) is generally 24 frames; today's high-standard screening halls mostly use giant screens with a width greater than 21.3 meters (such as IMAX halls, CGS (China Giant Screen, STARMAX, etc.) uses high-brightness lasers as light sources (such as laser halls), with resolutions up to 4K (such as 4K halls), and frame rates up to 120 frames (such as CINITY).
The sound return system determines the auditory effect of the movie. Traditional theaters use 2D surround sound, while high-standard theaters such as Dolby Atmos halls use 3D panoramic sound to bring a better listening experience.
Generally speaking, high-standard cinemas often have multiple high-standard projection technologies at the same time, such as "giant screen 4K laser hall" and so on.
When choosing a movie theater, the brightness of the 3D movie is dimmer, so it is better to choose the laser hall; horror movies with panoramic sound effects will bring a hearty frightening experience; the dynamic seats in the 4D hall are equipped with environmental special effects such as water mist and smell. , while bringing a richer experience to the audience, it can also easily make first-timers feel uncomfortable.
Therefore, it is necessary to choose different theaters based on the type of film and specific needs.
Currently, the mainstream high-end theaters on the market include IMAX, Dolby Cinema, CINITY and CGS China Giant Screen.
The feature of IMAX is the super large screen and IMAX camera specially shot, which allows the audience to see about 26%-40% more pictures than the ordinary screen.
At present, the most widely used one is digital IMAX, and the best one is laser IMAX. If it is a movie with IMAX exclusive format, it is recommended to watch it in an IMAX theater.
Dolby Cinema is composed of Dolby Vision with high restoration quality and Dolby Atmos that brings immersive experience. You need to look for the exclusive logo of "DOLBY CINEMA". The general "Dolby Hall" refers to only panoramic sound. Screening halls with sound technology, because Dolby Atmos can be used with any screen, but Dolby Vision is only used in Dolby Cinema.
Audiences who pursue the ultimate experience in sound and image quality can choose Dolby Cinema.
CINITY is the only theater in China that supports the screening of "4K+120 frames+3D", which can achieve the best viewing effect when watching high-standard movies.
CGS China Giant Screen is a domestically produced giant screen produced to compete with IMAX.
