During the Spring Festival, a number of movies are released, in addition to choosing a film, different theaters are also dazzling, IMAX hall, Dolby Atmos hall, CINITY hall, CGS Chinese giant screen hall, etc., what do these terms represent, and what is the difference compared with traditional movie halls?
These types of seats are not available
When you usually watch movies and buy tickets, if you want to choose the viewing position with the best audio-visual effect, it is not simply to choose the middle position, but you need to consider many factors such as movie type, theater specifications, screen size, step angle, screen angle and viewing needs.
For 2D films, according to the best viewing position guidelines published by the Society of Motion Picture and Television Engineers, the first thing is that the picture needs to occupy the audience's field of view as much as possible, and the angle between the audience and the sides of the screen should be at least 36°. Secondly, in order to avoid cervical fatigue, the elevation angle between the audience and the horizontal line of the screen should not exceed 35°.
Based on these two principles, the seats on both sides of the screen with a horizontal angle that is too small, the front row seats with a large elevation angle, and the last row of seats that are too far away from the screen and too close to the rear stereo will affect our audio-visual experience, so if you want to get a better viewing experience, you should not choose these kinds of seats.
Considering the comprehensive audio-visual effect, if it is a small hall with 8-14 rows, it is best to choose the front and back of the front and back in the middle position; If it is a central hall with 15-20 rows, it is best to choose the front and back center position of the first row; If you are in the lobby or IMAX hall of rows 21-25, it is best to choose the front and back center position of the first row.
If it is a 3D movie, because the 3D glasses will reduce the brightness of the screen by about 40%, so for better visual effects, you should sit on the position of the screen to the projection window 1 2.
The ticket prices for different locations in the same screening hall in the cinema are also priced according to the viewing effect, but because everyone's viewing needs are different, how to choose must be decided based on their own needs.
What is the difference between different theaters?
Many friends have noticed that movie ticket prices are also very related to the type of screening hall, so what is the difference between IMAX hall, CINITY hall, Dolby Atmos hall, etc., and traditional theater?
Film is an audio-visual art presented by the combination of sound and light technology, and the projection effect of a film is jointly determined by the projection system and sound playback system in the theater.
The quality of the projection system is closely related to the screen and projector, the traditional digital projection mostly uses ordinary screens, with low brightness xenon lamp as the light source, the resolution (affecting the clarity of the picture, positively correlated with the clarity of the picture) can reach 2K, the frame rate (the number of 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 are mostly more than 21 wide3-meter giant screens (such as IMAX hall, CGS China giant screen, Starmax, etc.) mostly use high-brightness lasers as light sources (such as laser halls), with a resolution of up to 4K (such as 4K hall) and a frame rate of up to 120 frames (such as CINITY).
The sound reproduction system determines the auditory effect of the movie, and the traditional theater uses 2D surround sound, and the high-standard theater such as the Dolby Atmos hall will use 3D panoramic sound to bring a better listening experience.
In general, high-standard theaters often have a number of high-standard projection technologies at the same time, such as "giant screen 4K laser hall". When choosing a movie hall, the brightness of the 3D movie is more dim, so it is advisable to choose a laser hall; Horror movies with panoramic sound effects will bring a hearty frightening experience; The dynamic seats in the 4D hall and environmental special effects such as water mist and smell not only bring a richer experience to the audience, but also easily make first-time testers feel uncomfortable. Therefore, it is necessary to choose different theaters based on the type of film and specific needs.
At present, the mainstream high-end cinema halls in the market are IMAX, Dolby Cinema, CINITY and CGS China Giant Screen.
IMAX features a large screen and an IMAX camera that allows the viewer to see about 26%-40% more than a regular screen. At present, the most widely used is digital IMAX, and the best effect is laser IMAX, if it is a movie with IMAX exclusive format, it is recommended to use it in IMAX theater**.
Dolby Cinema is matched by Dolby Vision with high image quality and Dolby Atmos that brings an immersive experience, and you need to look for the "Dolby Cinema" exclusive logo, the general "Dolby Hall" refers to a screening hall that only uses Atmos technology, because Dolby Atmos can be used with any screen, but Dolby Vision is only used in Dolby Cinema. Audiences who are looking for the ultimate experience of sound and picture quality can choose Dolby Cinema.
CINITY is the only theater in China that supports the projection of "4K+120 frames+3D", and with high-standard films, the best effect can be achieved. CGS China Giant Screen is a domestic giant screen produced by IMAX.
