After filming "Interstellar", the sci-fi movie will be suspended, unless the special effects technology can allow a special effects team of more than 1,500 people to show an extremely real, vast space and alien in about a year, compressing the film cycle into two years, otherwise the cycle will be too long.

It's the whole film, not just one or two shots, and it's not a repetition of going around in the background.

"Edge of Tomorrow" is filmed, the scene is on Earth, and "The Martian" is a special effect on the ground and the starry sky of Mars.

"Interstellar" also doesn't have overly complicated special effects.

After finalizing the first draft, Tang An did not rush to continue the creation of the script, and there was still a key issue in front of him.

Nolan originally used 70mm film IMAX to shoot, and in the end, there is basically no 70mm film used in domestic films.

In fact, even if you shoot with 70mm film, there can only be digital IMAX, ordinary digital, 35mm film version, and several versions in China.

As for the 70mm film IMAX, there are only 5 screens in China.

There are very few film IMAXs in the world, and IMAX companies are promoting IMAX digitization around the world at a lower cost.

The Huaguo giant screens developed by China Film Digital are also digital giant screens.

Even if you look at the world, less than 3% of movie theaters have 70mm film IMAX projection equipment.

No matter how good the shooting is, it is in vain, and the screening conditions can't keep up.

However, there is still some gap between the 70mm film and the 35mm film, even if it is projected on the digital MAX and giant screens.

After all, the quality of the film source is higher, so it will be better.

However, the playback equipment does not meet the requirements and cannot show the effect of the movie 100%.

Exactly how to weigh it up, or use digital shooting.

"The Martian" was shot with a 4K digital camera, and now it seems that the United States has developed a 6K digital camera.

The 35mm film is shot in 4K, and the post-production is almost 3.5K.

There is no 4K after the 4K camera shoots the post-production, and even if the post-production of "The Martian" is very detailed, it is only 3K, but the average audience can hardly tell the difference.

THE FINISHED FOOTAGE FROM A 6K DIGITAL CAMERA CAN REACH 4K AFTER POST-COMPRESSION, WHICH IS CLEARER THAN 35MM FILM.

However, there are not many domestic 4K digital projection equipment, and it is still in vain.

70mm film IMAX was the best option, but without cameras, there were only five in the world, so it was a question of whether or not they could be rented.

Even the same kind of equipment and screen, the projection effect is not the same, it may be the lens of the projector, the bulb and so on.

Not only the equipment, but also the suitability of the movie itself.

Different movies have different requirements for the picture, and most of "The Martian" is shot digitally, and some are shot on film.

There are too many problems, and there are 3D and 2D options, these Tang An can't make a decision alone, so today he brought Xiao Yang, the artistic director of Tiangong Color, Ye Jintian, the artistic director of the crew, and the leaders of the lighting and photography groups over, and studied them in the conference room.

Although there is no storyboard script, all of you are professional, and you can know the overall style of the movie after reading the first draft of the entire script.

Ye Jintian first said, "Tang Dong, the background of this film is in the last days, and the style of the overall picture in the early stage should be relatively gray, even if you rent a 6K digital camera, the effect will not be much better than the effect of 35mm film." ”

Photographer Zhang Li nodded, "Lao Ye is right, there is still a difference between digital images and analog images. ”

Tang An asked, "Is it possible to achieve similar results by adjusting the overall ambient lighting and adjusting the lighting in the later stage?"

Xiao Yang shook his head, "If you spend a few more months indoors, you can get close, but it's only close, but it's almost impossible outdoors, unless the exterior scenes are in the studio with a blue screen." ”

"Then exclude digital cameras. ”

Since it really doesn't work, Tang An is no longer entangled, and immediately makes a decision.

If you make a blockbuster film of the type "Transformers", there is almost no difference between digital and film.

Although the Martian ground in "The Martian" is all earthy yellow, in order to make the whole film feel positive to the audience and not make the audience pessimistic, the overall tone is relatively bright.

The post-apocalyptic background of "Interstellar", the exterior scene is also desolate, and the overall tone is gray.

Digital camera imaging is a digital image, and film is an analog image, just like the difference between an LCD TV and a desktop large color TV.

The color tone of the desktop large color TV is richer, and it is far more delicate than the LCD TV.

"For film, I'll go to Fox and Columbia to see if I can rent a 70mm IMAX camera, and probably more than a third of the lenses will use 70mm film. ”

The cost of "Interstellar" itself is not very high, and the use of 70mm film to shoot is also within the affordable range.

Although the IMAX camera is deadly heavy, there will definitely be a lot of shoulder resistance shooting in the movie, and he, the chief cinematographer, will definitely be one of the most tired people on the crew.

But Zhang Li doesn't care, it's all work.

Then there was the issue of 3D and 2D, and after a unanimous discussion, 3D shooting was abandoned.

As with the reason for choosing film, the current 3D technology is not very mature, and there are more dim shots at the beginning, and if you use 3D, the picture will be even darker.

And the original film is 170 minutes long, and some viewers can't stand the dizziness, so the gains outweigh the losses.

Even if Tang An compresses the plot, it is already the limit to reduce it by 15 minutes.

In Hollywood, there are many examples of movies hitting the street because the film is too long, and the producer forces the director to reduce the duration.

The 2005 high-profile blockbuster "Heavenly Dynasty" was brutally murdered because of Fox's intervention, and this great director Ridley Scott's standard work was cut by Fox for 50 minutes.

Ridley Scott's original stripped-down film was 192 minutes, but Fox cut it to 144 minutes.

With 50 minutes less, the plot will be unwatchable, and it will be pounced like a dog.

Of course, you can't blame Fox, no studio can allow the set to reach 192 minutes.

Ridley Scott couldn't fight Fox either, his arm couldn't twist his thigh, even though he was one of the producers.

Peter Jackson's "King Kong" was also nearly 190 minutes long, and in addition to himself being a producer, his wife was also a producer.

There is also a producer who is the screenwriter of the film and the screenwriter of the Lord of the Rings series.

The producers are all Peter Jackson's gang, so they can be so willful.

Nolan is the same, his wife is a professional producer, otherwise "Inception" and "The Dark Knight" can be shot with 70mm IMAX?

The producers of "Inception" are Nolan and his wife.

70mm film IMAX shooting is expensive, projection equipment is expensive, a 120-minute copy alone is 800 pounds, and it costs 300,000 yuan to make a copy, and the average projectionist has to go through a month of professional training before it can be screened.

So far there is not a single real IMAX movie in the world.

"Inception", "The Dark Knight", "Transformers 2", and "Mission Impossible 4" are the only four films that have been shot on 70mm film IMAX.

However, the IMAX duration is only half an hour, half an hour, 15 minutes, and 15 minutes.

"Avatar" is a digital IMAX, which was shot with a digital camera and then converted into IMAX.

There was almost an hour of footage in Interstellar that needed to be shot on 70mm film, and the rest on 35mm film.

Once successful, it will be one of the best IMAX movies in the country and even in the world.

Although there are only two Beijing Huaguo Science and Technology Museum and Beijing Huaguo Film Museum, one Chongqing Science and Technology Museum, one Guangzhou Science Center, and one Dongguan Wanda International Cinema in China, a total of 5 IMAX film screens.

These five screens are at least 278 meters high, which is much stronger than those digital IMAX screens in their early 20s or even more than 10 meters high.

However, even if it is shown on an ordinary screen, with a higher quality source, the effect is far beyond that of ordinary movies.

Of course, it is up to the people to make a decision, and everything depends on the results of the shooting, and everything will be closed before the filming is finished.

PS: It's a pity that this movie couldn't be watched on the film IMAX screen, when it was first released, there were only two IMAX film screens left in China, one in Beijing and Guangzhou, and the other three were replaced with digital screens, I wanted to watch Guangzhou, but I didn't have time to go....
