1
00:00:00,080 --> 00:00:06,400
So, you got your expensive graphics card, your overclocked octaore CPU, and

2
00:00:04,560 --> 00:00:11,120
more memory than a freaking elephant. But when you're playing the latest AAA

3
00:00:08,800 --> 00:00:16,080
games on your PC, or really anything else, for some reason, things don't seem

4
00:00:13,840 --> 00:00:19,920
quite right. Especially when you're looking at a scene where a lot of things

5
00:00:17,680 --> 00:00:25,039
are moving around at once or the camera's panning. Because even with all

6
00:00:22,480 --> 00:00:30,000
that horsepower under the hood, motion blur is a problem on even the most

7
00:00:27,519 --> 00:00:35,120
powerful rigs. And if you're gaming on a VR headset like the Oculus Rift, it can

8
00:00:32,559 --> 00:00:38,800
be even more distracting. Now, to be clear, we're not talking about the kind

9
00:00:36,719 --> 00:00:43,440
of motion blur that is intentionally added to a game in post-processing. What

10
00:00:41,200 --> 00:00:48,640
we're talking about is unintentional motion blur caused by excessive pixel

11
00:00:46,320 --> 00:00:53,039
persistence. You see, an electronic display, whether it's a computer monitor

12
00:00:50,399 --> 00:00:57,520
or a headset or a phone, is made up of millions of individual pixels that

13
00:00:54,960 --> 00:01:01,039
change their brightness and color to create an image that you see. So,

14
00:00:59,520 --> 00:01:04,960
whenever the image on the screen changes, which is nearly constantly if

15
00:01:03,120 --> 00:01:10,159
you're playing a game that isn't Pong, the pixels cannot respond

16
00:01:07,880 --> 00:01:14,240
instantaneously. With a typical LCD monitor, there's actually delay of a few

17
00:01:12,159 --> 00:01:19,119
milliseconds before the pixels can actually change. Now, while there are

18
00:01:16,960 --> 00:01:23,600
fast response monitors which have a delay or response time of just 1 or two

19
00:01:21,439 --> 00:01:28,479
milliseconds, which helps to cut down on motion blur significantly, even those

20
00:01:26,560 --> 00:01:34,640
don't completely solve the problem. In fact, even if a zero millisecond monitor

21
00:01:32,000 --> 00:01:40,240
existed, there's still an issue with how LCD displays actually show images to us.

22
00:01:38,079 --> 00:01:44,320
Like other pieces of digital hardware, an LCD display works by sampling image

23
00:01:42,640 --> 00:01:49,680
data it gets from the computer many times a second and displaying the

24
00:01:46,320 --> 00:01:51,840
samples as a series of still images.

25
00:01:49,680 --> 00:01:56,479
These still images are then displayed at a rate equal to your screen's refresh

26
00:01:53,680 --> 00:02:01,439
rate, usually 60 Hz, and your brain interprets this as movement. However,

27
00:01:59,119 --> 00:02:05,439
your eye is not a piece of computer hardware, unless of course your name is

28
00:02:02,799 --> 00:02:10,000
Adam Jensen. Human eyes are really good at perceiving differences in fluid

29
00:02:07,680 --> 00:02:16,560
motion. And while high refresh rate displays that operate at 144 hertz or

30
00:02:13,280 --> 00:02:19,040
even higher look great, they still can't

31
00:02:16,560 --> 00:02:23,200
completely fool our brains just by showing us a series of static images.

32
00:02:21,360 --> 00:02:27,840
And as if the problem of motion blur weren't bad enough on computer monitors,

33
00:02:25,360 --> 00:02:32,000
it's much worse if you're using an Oculus Rift or VR headset like I

34
00:02:30,000 --> 00:02:36,959
mentioned before. While motion blur might just be an annoyance if you're

35
00:02:34,000 --> 00:02:42,560
gaming in 2D on a desktop PC, it can actually make you sick on a 3D display

36
00:02:40,080 --> 00:02:47,599
like the Oculus Rift. Because these headsets work by surrounding your field

37
00:02:45,200 --> 00:02:52,640
of vision in immersive 3D environments, motion blur in these situations can make

38
00:02:49,599 --> 00:02:54,879
you feel physically out of balance with

39
00:02:52,640 --> 00:02:59,360
your surroundings and cause a very similar nausea to what you'd feel in a

40
00:02:57,519 --> 00:03:04,720
car or an airplane in the same situation. So, the solution itself is a

41
00:03:02,400 --> 00:03:08,879
pretty simple idea. Well, let's just cut down on how long individual pixels are

42
00:03:07,280 --> 00:03:12,879
displayed so that we don't we're not out of sync. But how are display

43
00:03:10,879 --> 00:03:17,200
manufacturers going to accomplish this? Well, one way is through a technique

44
00:03:14,879 --> 00:03:22,480
called backlight strobing. Typically, modern LCD monitors are illuminated by a

45
00:03:19,519 --> 00:03:26,480
backlight that's always on. However, in a display that uses backlight strobing,

46
00:03:24,720 --> 00:03:32,239
the backlight instead switches on and off rapidly, reducing the amount of time

47
00:03:29,280 --> 00:03:36,640
that you actually see each pixel. This is very similar to the way that CRT

48
00:03:34,480 --> 00:03:40,799
displays, which were, you know, for the kids that weren't alive in the time of

49
00:03:38,720 --> 00:03:46,159
the dinosaurs, which are those old tube things that existed before LCDs came

50
00:03:43,599 --> 00:03:50,799
onto the market, and is the reason that CRTs have historically been better at

51
00:03:48,959 --> 00:03:54,560
displaying scenes with fast motion, at least to our eyes. There are a number of

52
00:03:53,120 --> 00:03:59,200
monitors on the market that feature backlight strobing combined with high

53
00:03:56,720 --> 00:04:04,000
refresh rates to reduce motion blur as much as possible while still maintaining

54
00:04:01,760 --> 00:04:09,280
the picture quality and low energy consumption, not to mention the space

55
00:04:05,599 --> 00:04:11,200
savings of a flat panel LCD. Of course,

56
00:04:09,280 --> 00:04:15,360
it's also possible to ditch the backlight altogether and go a different

57
00:04:13,439 --> 00:04:20,639
route. So, the consumer version of the Oculus Rift features a display based on

58
00:04:17,359 --> 00:04:22,720
organic LEDs or OLEDs. OLEDs can

59
00:04:20,639 --> 00:04:27,360
generate their own light through the use of specialized organic compounds. But

60
00:04:25,040 --> 00:04:32,000
more importantly for gamers, OLEDs have a very quick response time, much faster

61
00:04:29,759 --> 00:04:36,479
than the pixels in a conventional LCD. And not only does this cut down on

62
00:04:33,680 --> 00:04:41,120
motion blur on its own, the low response times allow OLEDs to interpolate frames

63
00:04:39,040 --> 00:04:45,919
easily, meaning that your system can guess missing frames in a given second

64
00:04:44,080 --> 00:04:49,520
to match your display's frame rate. Or if you're just watching a movie recorded

65
00:04:47,600 --> 00:04:53,120
at the usual 24 FPS and you want your experience to be less cinematic, I guess

66
00:04:51,040 --> 00:04:58,000
it could do that, too. So whether you're gaming in 3D using a headset or just a

67
00:04:56,000 --> 00:05:02,400
monitor with 3D glasses, these technologies will help you do your thing

68
00:05:00,639 --> 00:05:06,639
without feeling like you're on some kind of vomit inducing carnival ride.

69
00:05:04,880 --> 00:05:10,400
Speaking of vomitinducing carnival rides, our sponsor today is Fractal

70
00:05:08,639 --> 00:05:15,199
Design. And boy, do we have a treat for you. Instead of telling you guys about

71
00:05:12,639 --> 00:05:19,520
their, you know, Scandinavian designed cases and power supplies and cooling

72
00:05:17,759 --> 00:05:24,000
products, we're having Luke wrap up here. Look, we had this conversation

73
00:05:22,240 --> 00:05:28,400
already. I told you I have to host this because you just can't do a good enough

74
00:05:25,360 --> 00:05:30,560
job of it. So, I'm super done. I'm sick.

75
00:05:28,400 --> 00:05:33,840
This is ridiculous. I've I've been trying to build this company for like 2

76
00:05:32,160 --> 00:05:37,840
years. We don't have to roll the camera on this. Like, okay, look, if you need

77
00:05:35,680 --> 00:05:41,759
to talk about this, then you need to talk to yourself about how you run the

78
00:05:39,840 --> 00:05:46,080
company. No air conditioning. People are like overheating all the time. Um, I'm

79
00:05:44,639 --> 00:05:52,000
working while I'm sick. I have to get my doctor's appointment because I have to tape you up. Look, I think What even is

80
00:05:49,680 --> 00:05:55,120
that? Like I've been sick for like 2 months. I finally get a doctor's

81
00:05:53,520 --> 00:05:58,479
appointment with my family doctor and you don't you make me not go because of

82
00:05:56,720 --> 00:06:02,800
masking tape. Well, I think you're I think Look, okay, but we were supposed

83
00:06:00,800 --> 00:06:07,039
to have you do the spot and you were supposed to do Josh's thing. I get

84
00:06:05,120 --> 00:06:14,560
dragged into the office and I have to film this. It's not like I wanted to

85
00:06:10,680 --> 00:06:19,400
like Okay, you know what? Just I'm done.

86
00:06:14,560 --> 00:06:19,400
We'll talk later. No, I'm just done.

87
00:06:23,759 --> 00:06:26,759
You

88
00:06:28,680 --> 00:06:34,319
um so sorry. I hope that wasn't too awkward. Guys, like the video if you

89
00:06:32,880 --> 00:06:37,600
liked it. Dislike it if you disliked it. Leave a comment. Um, if you have

90
00:06:35,919 --> 00:06:42,479
suggestions for future fastest possibles that I guess won't be hosted by Luke.
