1
00:00:00,280 --> 00:00:06,080
so with our technology rapidly improving and our graphics cards and digital

2
00:00:04,279 --> 00:00:09,840
cameras pumping out crisper more lifelike images than ever before it

3
00:00:08,000 --> 00:00:14,320
isn't surprising that we're wondering how long it will be until we get

4
00:00:11,880 --> 00:00:20,600
something that could match or exceed our eyes natural resolution or refresh rate

5
00:00:17,600 --> 00:00:22,920
but what exactly are the specks of our

6
00:00:20,600 --> 00:00:27,760
eyes does the question even make sense since we see things not with a camera

7
00:00:24,720 --> 00:00:30,439
lens and GPU but with a squishy eyeball

8
00:00:27,760 --> 00:00:33,719
and a hunk of meat inside our brain now we here at Techquickie are not the

9
00:00:32,079 --> 00:00:38,879
first to answer this question in terms of discrete numbers but even so tons of

10
00:00:36,920 --> 00:00:43,600
people out there are still perpetuating the same myths like the famous assertion

11
00:00:41,760 --> 00:00:49,079
that the human eye can't see more than 24 frames per second which Garners eye

12
00:00:46,600 --> 00:00:53,879
rolls from enthusiasts everywhere so we're going to take a stab at explaining

13
00:00:50,960 --> 00:00:58,640
the truth obviously our eyes don't work exactly the same way as digital cameras

14
00:00:56,520 --> 00:01:03,239
but they do operate with a few Concepts in common just like an image sensor in a

15
00:01:01,280 --> 00:01:09,320
camera can capture a certain number of pixels our eyes have a finite number of

16
00:01:05,840 --> 00:01:11,439
Rod and Cone cells in them plus our eyes

17
00:01:09,320 --> 00:01:15,600
need different visual elements of whatever we're looking at to be small

18
00:01:13,560 --> 00:01:21,320
enough so that they don't appear pixelated so in this way our eyes are

19
00:01:18,320 --> 00:01:23,560
sort of kind of digital but our brains

20
00:01:21,320 --> 00:01:28,840
render images we can understand by examining how the view from our eyes is

21
00:01:26,240 --> 00:01:33,079
continuously changing which sounds a lot closer to how and analog technology

22
00:01:30,920 --> 00:01:39,360
Works something you can learn more about up here so this means that the commonly

23
00:01:35,920 --> 00:01:40,640
cited answer of 576 megapixels which was

24
00:01:39,360 --> 00:01:46,320
decided upon with some rather complicated math which we've linked to in the video description needs to be

25
00:01:44,119 --> 00:01:50,920
taken with some caveats don't get me wrong our eyes are indeed incredible

26
00:01:48,640 --> 00:01:58,320
tools for seeing the world in detail I mean 576 megapixels is equal to having a

27
00:01:54,799 --> 00:02:01,159
32,000 by 18,000 pixel monitor this

28
00:01:58,320 --> 00:02:08,720
would be like having an array of over 275 1080p monitors this makes it sound

29
00:02:05,640 --> 00:02:11,319
like you'd need 576 million pixels to

30
00:02:08,720 --> 00:02:15,200
have a photo that fit exactly within your field of view to completely fool

31
00:02:13,599 --> 00:02:19,720
you into thinking that the picture is actually real life but remember that

32
00:02:17,840 --> 00:02:23,560
since you only see things sharply that are right in front of you with your

33
00:02:21,400 --> 00:02:28,640
peripheral vision being a lot blurrier the actual number is only somewhere

34
00:02:25,480 --> 00:02:31,080
around 8 or 9 megapixels and again since

35
00:02:28,640 --> 00:02:35,400
your brains don't work in a digital manner the real number can vary quite a

36
00:02:33,360 --> 00:02:39,239
bit depending on factors like ambient lighting but let's say you're less

37
00:02:37,440 --> 00:02:43,280
worried about buying a camera that can match the capabilities of the human eye

38
00:02:41,360 --> 00:02:47,840
and more about buying a graphics card and high refresh rate monitor that can

39
00:02:45,480 --> 00:02:53,560
crank out so many FPS that your favorite game couldn't possibly appear any

40
00:02:50,120 --> 00:02:56,480
smoother is that even possible well

41
00:02:53,560 --> 00:03:00,680
possibly in theory a human brain could process a th000 frames per second

42
00:02:59,000 --> 00:03:06,000
according to scientific Research into how quickly our neurons can fire signals

43
00:03:03,720 --> 00:03:10,319
but just like the theoretical Max speeds of things like SATA drives this number

44
00:03:08,280 --> 00:03:15,360
doesn't mean a whole lot in Practical terms different people have different

45
00:03:12,879 --> 00:03:21,519
maximum refresh rates and the real life upper limit seems to be around 250 Hertz

46
00:03:19,239 --> 00:03:26,239
depending on what study you look at but remember again that our brains and eyes

47
00:03:23,280 --> 00:03:31,120
aren't exactly digital and don't render discret frames the way a graphics card

48
00:03:28,680 --> 00:03:36,799
would so there is an actual number of frames your eyes can push to your brain

49
00:03:33,640 --> 00:03:39,040
rather that 250 number is the point at

50
00:03:36,799 --> 00:03:43,439
which motion becomes realistic looking for people with good eyesight and of

51
00:03:41,360 --> 00:03:47,239
course there are diminishing returns as you approach this number for example

52
00:03:45,560 --> 00:03:54,799
it's easy for most people to tell the difference between 20 and 60 FPS but 220

53
00:03:51,519 --> 00:03:58,280
and 260 will be indistinguishable to a

54
00:03:54,799 --> 00:04:00,519
lot of folks so while it is possible to

55
00:03:58,280 --> 00:04:04,920
attach meaningful numbers to the spec sheets of our eyes and brains individual

56
00:04:02,959 --> 00:04:09,159
differences along with the not quite analog or digital nature of our bodies

57
00:04:07,640 --> 00:04:13,360
means that you should take them with a grain of salt and that the most

58
00:04:11,319 --> 00:04:17,680
important thing is to buy stuff that will give you an experience that you

59
00:04:15,400 --> 00:04:23,520
think looks good unless of course you're cool with waiting around for the world's

60
00:04:19,440 --> 00:04:26,440
first 18,000 P monitor to hit the market

61
00:04:23,520 --> 00:04:29,479
whoa I'm on Techquickie anyways tunnel bear VPN you can tunnel up to 20

62
00:04:28,240 --> 00:04:34,199
different countries and browse the internet internet as if you are in that

63
00:04:32,000 --> 00:04:38,479
country they have easy to use apps for iOS Android PC and mac and they also

64
00:04:36,440 --> 00:04:42,360
have a Chrome extension just choose the country that you want in the app turn

65
00:04:40,440 --> 00:04:46,280
tunnel bear on and watch as your bear tunnels your internet connection to a

66
00:04:43,720 --> 00:04:50,919
new location similar to how I just came here from LTT when you turn tunnel bear

67
00:04:49,199 --> 00:04:55,880
on two things happen your connection gets encrypted with AES 256bit

68
00:04:53,120 --> 00:04:59,360
encryption and your public IP address gets switched so you show up to other

69
00:04:57,880 --> 00:05:04,039
people as if you're in that country that you picked earlier they also have a

70
00:05:01,320 --> 00:05:08,479
toprated privacy policy and do not log user activity you can try tunnel bear

71
00:05:06,000 --> 00:05:12,600
VPN with 500 megabits of free data and with no credit card required and if you

72
00:05:10,560 --> 00:05:16,840
decide to get the unlimited data plan you can save 10% by going to Tunnel

73
00:05:14,280 --> 00:05:20,720
