Episode Overview

The episode explores how and why TV picture modes differ, delving into the technical side of color science and display calibration. Michael calls in to ask why cinema-modest modes feel “warmer” or even sepia-like compared to vivid, punchy modes, and Scott explains the physics, perceptions, and industry standards that drive these visual distinctions.

Key Discussion Points and Insights

1. Listener Question: Why Do Picture Modes Look So Different?

[01:36] Michael (Caller)

• Asks about the notable difference between modes like film/movie versus vivid/game.
• Observes that film modes often seem “sepia tone” or “brownish,” while vivid modes make blues pop.
• Wonders about the reasoning and science behind these differences and their connection to creator intent.

Notable Quote:
“It almost seems kind of like a sepia tone, if that makes sense, a brownish to it as opposed to like a bright, vivid color... what is behind that?”
— Michael [01:36]

2. Scott Explains: The Science Behind Picture Modes

[02:42] Scott Wilkinson

• Picture Modes & White Point:

  • “Film mode, filmmaker mode, cinema mode, movie mode... have a warmth to them, a slightly reddish or sepia tone, especially when compared to vivid or game mode. This is mostly due to where something called the white point is located in the CIE diagram.”
  • Introduces the CIE chart—a tool for mapping all visible colors—and the concept of the black body locus.

• Black Body Locus and White Point:

  • The “white point” determines what the TV regards as “white,” fundamentally affecting color reproduction.
  • Vivid/Game modes: White point shifted towards blue (often 9000K), making images cooler and “punchier.”
  • Cinema/Filmmaker modes: White point set at D65 (6500K), which is what content creators use to master their content and is considered a “neutral,” accurate white.

Notable Quote:
“The white point is basically the canvas on which the TV paints its picture. And if the white canvas is a little bit on the blue side, then everything... is going to have a blue tone to it.”
— Scott Wilkinson [03:50]

[06:15]
D65 (6500 Kelvins) is the standard for professional video work:
“That’s the white point you want your TV to reproduce so that what you see... looks as close as possible to what the content creators were looking at.”
— Scott Wilkinson [06:32]

---

3. Why Is Vivid Mode the Default in Stores?

[09:17] Scott Wilkinson

• Retail Display & Perception:
  • Human eyes perceive higher color temperatures (bluer whites) as “brighter,” even if measured brightness is identical.
  • Retailers set TVs to Vivid to capture attention on the sales floor.
  • “If you put a TV in cinema mode next to a TV in vivid mode... the cinema mode will not look as punchy. It will not look as bright, even if they measure the same.”
  • When customers bring TVs home, they're often still set to punchy, blue-heavy defaults (“standard” mode), which are still too blue compared to the D65 target.

Notable Quote:
“It even will look perhaps a bit on the reddish side or sepia side. And that’s unfortunate. That’s an unfortunate side effect of retail.”
— Scott Wilkinson [10:22]

---

4. Why Choose Cinema/Filmmaker Mode at Home?

[10:55] Scott Wilkinson

• Creator Intent & Viewer Experience:
  • Advocates for watching content as creators intend, meaning as close to D65 white point as possible.
  • Acknowledges that warm modes may initially appear dimmer or redder, but viewers quickly adapt.
  • Notes health benefits: less blue light is easier on the eyes and may aid in better sleep.

Notable Quote:
“I recommend watching the tv, watching the content as the creators intended. And that means cinema mode... less bright and punchy and wowy, zowie, and more authentic.”
— Scott Wilkinson [11:32]

• Blue Light and Eye Strain:
  • Too much blue in the image can cause eye strain and disrupt sleep, especially when watching late at night.

---

5. Bonus Q&A: Room Lighting & Color Perception

[14:40] Scott Wilkinson (Bonus listener question)

• Room Lighting Matters:
  • The color temperature of your room’s light bulbs can affect how your TV image appears.
  • Recommends using D65 (6500K) lighting in a home theater for the most accurate color viewing.
  • Lower temperature bulbs (like 2700K) introduce a yellow tint and can bias perception.

Notable Quote:
“In fact, the light bulbs in my theater room are D65 white... That’s going to bias your lights and the color you see on the screen, even if your screen is in filmmaker mode.”
— Scott Wilkinson [14:53]

---

Memorable Moments & Notable Quotes

• On the science of the black body locus:
  “This line indicates the color that a particular theoretical object called a black body... will radiate as it’s heated to higher and higher temperatures.”
  — Scott Wilkinson [04:19]

• On adjusting to cinema mode:
  “Once you pick cinema mode, you might at first say, ‘oh, that’s dim and it’s red and I don’t like it.’ ...But after a little while, not very long at all, you will get used to it.”
  — Scott Wilkinson [11:49]

[Scott Wilkinson]

Hey there, Scott Wilkinson here, the home theater geek. In this episode. I answer a question from Michael, who actually sent in an audio file. So check it out.

[Michael]

Hey Scott, this is Michael calling from Long Beach, California. Spoke to you before in the past and question for you about TV modes. You know, you've spoken oftentimes about, you know, there's different. There's film mode, there's movie mode, there's vivid, there's game. And one of the things that I have seen that I actually do like very much is kind of like a warm film mode. And invariably it almost seems kind of like a sepia tone, if that makes sense, a brownish to it as opposed to like a bright, vivid color. And you know, you often say that, you know, filmmakers are creating these works, whether it's films or tv with a certain. And I'm just curious, like, what, what is behind that? Because it has a very distinct look to it. It is so different than like a vibrant mode where like blues and blues pop out. Just curious what your information is on that and I think it'd be interesting for people to hear. Thank you, sir.

[Scott Wilkinson]

Hey, thanks, Mike. Great question. Yeah, this is you. You've recognized something really important. I think you're exactly right. Film mode, filmmaker mode, cinema mode, movie mode. The modes that I recommend from the preset picture modes do appear to have a warmth to them. A slightly reddish or sepia tone, especially when compared to vivid or game mode. And this is mostly due to where something called the white point is located in the CIE diagram. It shifts around in the various picture modes. If we take a look at, at a CIE chart, which is this familiar horseshoe shape, and it has all the different regions of different colors within it, there are three. Basically, everything you can combine, red, green and blue, fills into this chart. Actually, this chart is what everything the human eye can see. And when you combine red, green and blue, you get a triangle within the chart. But that's not what I'm talking about today. What I want you to focus on today is this curved line in the center of the chart, a little bit lower than dead center, called the black body locus. Great name. This line indicates the color that a particular theoretical object called a black body, the color that it will radiate as it's heated to higher and higher temperatures. Now, in reality, there's no such thing as a perfect black body, but you can pretend there's one for physics and take a look at how it behaves as you heat it up. And as you heat it up, as you might imagine, as you heat something up, it, it starts to glow, and it might glow or start to glow orange and then get a little yellow and then get whiter and whiter and whiter and eventually blue. So that's where the name Black Body Locust comes from. And what it means in this chart is where is white? Where is the point that defines what, what the TV will reproduce as white? And you can see some of them are lettered A, B, C, D, E, and so on. Now, in the vivid or game modes, the white point is near the end, near the left end of this black body locus. It's past the point labeled C, and as you can see if you take a look there, it's actually into the blue area. Now, the white point is basically the canvas on which the TV paints its picture. And if the white canvas is a little bit on the blue side, then everything that it tries to reproduce, every image it tries to reproduce is going to have a blue tone to it, or a blue tinge, if you will. Now, cinema mode or movie mode or filmmaker mode is the mode closer to what content creators use when they're making their content. And the white point they use is the one here labeled D. It's called D65. It corresponds to what's called a color temperature of 6,500 K or kelvins, which corresponds to the temperature at which that you would need to heat an ideal black body to. To get that color of white when it glows. The point, the white point of Vivid mode is more like 9000k or more and it's the black body is starting to glow blue a little bit. But what the content creators use is this D65 point and I always recommend that that's the white point you want your TV to reproduce so that what you see on the TV or a projector, your video display looks very close or as close as possible to what the content creators were looking at when they made the content. Now you, as you rightly point out, if you were to compare, if you take an image and you look at it in vivid mode and then you look at it in cinema mode, yes, cinema mode will start to look a little reddish, possibly or warm. I would prefer to use the term warm, certainly warmer than Vivid mode, which looks very cool because it has a blue, more of a blue component in it. D is actually D65 is actually quite neutral, but by comparison it can indeed look slightly reddish.

Now why do we even have a Vivid mode? Well, to our visual system, to the human visual system, anything with a higher color temperature white point appears to be brighter. So if it's bluer, it looks brighter even if the measured brightness is no different than the other modes. This is why TVs in retail stores are usually set to Vivid mode. They are placed next to a bunch of other TVs on a big TV wall. Right? And they're all competing for your eyeball's attention. And so they all want to be as bright as possible. And one way to enhance that is for them to be bluer, to be in vivid mode, to have that white point over into the blue. If you put a TV in cinema mode next to a TV in vivid mode and you compare them, the TV in cinema mode will not look as punchy. It will not look as bright, even if they measure the same. It even. It even will look perhaps a bit on the reddish side or sepia side. And that's unfortunate. That's an unfortunate side effect of retail. All the TVs want to compete with each other, so they all go into vivid mode. In fact, when you first buy a tv, it may very well ask you the first time you turn it on, is this going to be a store demo, or is this going to be in the home? And if you click on store demo, boom, it's going to be in vivid mode because the manufacturer knows they want it to be in vivid mode on the showroom floor. So, of course, you wouldn't select that when you first buy a TV and bring it home. You would buy using it in the home. Even then, it will probably be in what's maybe called the standard picture mode or something like that. And that's still going to be too blue. It's going to be to the left of D65 on that chart. And you want it to be as close to D65 as possible to be accurate. Now, most people get used to it after a while. Once you pick cinema mode, you might at first say, oh, that's dim and it's red and I don't like it. Some people even keep their TVs in vivid mode because they prefer it. Okay, I'm not going to argue with that. If that's what you like, then go for it. Go forth and be happy. But I recommend watching the tv, watching the content as the creators intended. And that means cinema mode, which means less bright and punchy and wowy, zowie, and more authentic. It's also easier on the eyes. I mean, there's been a lot of news lately about, you know, people watching screens, especially late at night. And having a lot of blue in the image makes it harder to sleep. It also causes more eye strain. So I still recommend people select cinema, movie or filmmaker mode. And after a little while, not very long at all, you will get used to it. You won't see it as sepia or red. You'll see it as accurate. And that's why I recommend it so thanks for the question.

Oh hey, Here we go. Keith's 512. Surely the color changes depending on what color light bulbs you have in your room. So 2700K looks very yellow. That's true. If you're watching TV with a light on, is 5000K a good choice? That's a great question. I'm sorry, I didn't. Didn't see that before the end of the episode. It's not really related, but I mean it is kind of. But in any event, yes, I. In fact, the light bulbs in my theater room are D65 white because exactly as you say, if you put a normal light bulb in there, which is at 2700k or something, that's going to impact, that's going to bias your lights and the color you see on the screen, even if your screen is in filmmaker mode or cinema mode. So in fact, when my lights are on in my theater room, they're D65 white, so that's a good question.
