Artistic Intent – Why We Are Here
The Producers and Directors all believe that if they make their vision come to life – make the story into a movie – it will be shown in a way that makes the audience see and hear what they created with the same splendor they created. Were they wrong?
Quality Management Basics
If something is managed properly, then there is control over the quality of the items being delivered, and assurance that the end user will be satisfied. Quality Management | Quality Control | Quality Assurance

Cinema Basics – Audio
Some say that a movies sound is 50% of the movie. So, it better be good, eh?
Cinema Basics – Picture
Sound has nuance. Picture has a thousand words for nuance. Let's learn some.
Your picture and sound equipment get calibrated according to a schedule that management thinks is appropriate for your facility – sometimes in 6 month or 12 month or 18 month intervals. But we all know that things happen in between. With the right tools, you can become the judge.
Some of our customers use the large speaker systems to know what the actors are saying, some read the words with special "closed caption" equipment...some listen to special tracks on headphones. The equipment is called Accessibility Equipment. We have to understand it and test it to make certain our customer gets the best experience possible.

Life happens in real time. Sometimes we read about it. More rarely, we are there. And after, we wish that we could have practiced a little bit before being thrown into it.
Checking Color Without a Meter
During the first minute of the Faces DCP, the screen shows a black background with a blue bar going across the middle. After a while the black background goes grey on one side. You’ll notice when you look at the two ends of the blue bar now that they look different – one more solid blue, one softer. When the background goes solid black, the bar looks solid blue from end to end again.
When we walk into the auditorium to do our task attempt to judge whether the picture quality in an auditorium is correct, we have to be aware that the Human Visual System can be tricked. Perhaps that is the wrong way to say it. In fact, the Human Visual System uses tricks to get around the limitations that it has.
One example is the number of color sensors we have in the eye. For many reasons, we have 100 million sensors squeezed onto the inside of each eyeball. But only about 6 million are sensitive to color. On average, 4 million are sensitive to red light, 2 million to green light, and only a few hundred thousand are sensitive to blue light.
The major idea behind the two Faces Test DCPs is that the Human Visual System and the Human Hearing System work magic. To test the picture in your auditoriums, we have to somehow get around that magic.
One part of the magic is that people’s eyes adjust to different light levels. We have the ability to see in dark moonlight and in bright sunlight. We can see great detail in our center vision, and we can see minute motion in our side vision.
The eyes and the brain work together to give the best image possible in different circumstances. We call the combination “The Human Visual System.”
We hear sound in a similar way. In a quiet room we can here a fan or even a mosquito that is 3 meters (10 feet) away. In a loud kitchen, we can hear voices that are softer than the loud pots and pans. (Well, sometimes.)
We certainly can’t hear that mosquito among the kitchen noises. And we can’t see a dark cat go by in the shadows if there are headlights making the the scene too bright.
Usually this magic is a great thing. It is an automatic process that protects the eyes, yet lets us see through an incredible range of light in the right circumstances.
But it also means that when we see leaves of green and fields of rice waving in the wind, we presume that the clouds are white and the sky is blue …but they might really be grayish white and a light shade of blue.
This especially happens in a movie theater. The sun or reflections that we see outside are hundreds, even thousands of times brighter than a projector can display on the screen. Yet, we believe it is bright white. And that is what matters to the audience.
But we have to check that the projection system is giving all that can be expected, not wimping out or giving too much of one color or not enough of another.
Sound is the same way. It is a rare person who can hear a tone and accurately say with certainty, “That is the note ‘E’ below middle ‘C’ on the piano for example, or how soft it is or how loud. All we can say is that it is soft or loud in comparison to something else.
Our purpose is to test the system, to see if it has the right amount of light (and sound). How do we get around this amazing capability of the Human Visual and Hearing Systems?
One thing that people can do very well is determine if faces look right. So, your editor went to a photo sharing site and dropped a bunch of faces on top of each other and made a movie for the projector (called a DCP – a Digital Cinema Package). We think it turned out to be a very interesting way for you to judge the quality the projected pictures on your screen.
And, like the other DCPs, there are also clean and distorted and muted tones – high and low notes – to judge the quality of your sound. Oh~! and let’s not forget the subtitles.
Watch it in your auditoriums several times. Pretty soon you will get a feeling that some face is too green or the expected white isn’t actually white. But, you won’t be certain. Watch and listen more. Pretty soon you will be certain.
Have someone download the DCP and install it on some projection systems. The DCP is at: Faces1 – 2K The passcode is QA_b4_QC
Here is a quicktime version of the Faces1 DCP – Have fun, and tell us what you think. With your help we can make a system that helps you tell the tech what is wrong and eliminates the complaints of the audience member.
