1
00:00:00,199 --> 00:00:09,120
you know how in movies some important person can just walk into a room wave

2
00:00:06,080 --> 00:00:11,880
their hand say and hands and they get

3
00:00:09,120 --> 00:00:16,680
like this super detailed closeup of the drug kingpin's nose hair or whatever

4
00:00:14,679 --> 00:00:21,119
well for most of us the experience of trying to enlarge a photo more often

5
00:00:19,160 --> 00:00:25,960
results in a blur that looks like a smear of melted rainbow ice cream now

6
00:00:24,160 --> 00:00:30,640
we've tried to solve this problem in recent years with digital cameras that

7
00:00:28,279 --> 00:00:35,000
capture images with ever higher pixel counts as well as more powerful

8
00:00:32,960 --> 00:00:39,440
computers that can process these images more easily but what if that's not good

9
00:00:37,520 --> 00:00:44,120
enough and you want something that will still look good when it's blown up to

10
00:00:41,360 --> 00:00:48,680
the size of Kim Kardashian's Caboose well this is where vector graphics can

11
00:00:46,399 --> 00:00:54,960
be extremely helpful since they can be rescaled to be as big or as small as

12
00:00:52,039 --> 00:01:00,519
you'd like without any loss of quality but how is that even possible well you

13
00:00:57,359 --> 00:01:03,440
see the reason that traditional raster

14
00:01:00,519 --> 00:01:10,159
images tend to blur and distort when you resize them is because the image file

15
00:01:06,479 --> 00:01:13,159
itself it's like a JPEG or a PNG is

16
00:01:10,159 --> 00:01:15,680
really just a collection of instructions

17
00:01:13,159 --> 00:01:20,880
that tell the computer how many pixels there are what color they should be and

18
00:01:18,320 --> 00:01:26,240
where they go so if you take a lower resolution JPEG and try to stretch it

19
00:01:23,759 --> 00:01:31,840
out Beyond how many pixels are actually defined in the file the computer has to

20
00:01:28,880 --> 00:01:37,560
just guess at what the other pixels in the enlarged image would be a very

21
00:01:35,040 --> 00:01:45,000
imperfect science that might be okay for something like blowing up a 4x6 to a 5x7

22
00:01:41,439 --> 00:01:47,000
for the wall but can result in horrible

23
00:01:45,000 --> 00:01:52,439
looking enlargements and the bigger you go the worse it gets vector graphics on

24
00:01:50,280 --> 00:01:57,799
the other hand work in a fundamentally different way instead of telling a

25
00:01:54,680 --> 00:02:01,000
computer what pixel goes where Vector

26
00:01:57,799 --> 00:02:04,079
files Define images using lines and

27
00:02:01,000 --> 00:02:07,119
shapes and their positions relative to

28
00:02:04,079 --> 00:02:10,239
each other for example the file might

29
00:02:07,119 --> 00:02:12,680
tell the computer I want a line here a

30
00:02:10,239 --> 00:02:18,080
triangle here and a curve that bends exactly like this in some other place

31
00:02:16,040 --> 00:02:23,920
the computer can then render these instructions into a nice looking smooth

32
00:02:21,160 --> 00:02:29,080
lined image each time you enlarge or Shrink it a little like a graphics card

33
00:02:26,680 --> 00:02:34,160
can render a frame of a video game in any resolution you choose providing your

34
00:02:31,800 --> 00:02:39,720
video card can handle it from a set of instructions specifying where things

35
00:02:36,680 --> 00:02:41,800
like polygons should go and because

36
00:02:39,720 --> 00:02:46,840
these instructions remain exactly the same no matter how large or small the

37
00:02:44,159 --> 00:02:51,120
image ends up being Vector files have the significant advantage of taking up

38
00:02:49,080 --> 00:02:55,519
the same amount of space on your computer's drive so you can end up with

39
00:02:53,400 --> 00:03:00,720
an image large enough to look crisp on a highway billboard while still taking up

40
00:02:57,840 --> 00:03:06,879
less than a megabyte well G Linus that sounds fantastic with better quality and

41
00:03:03,840 --> 00:03:10,200
smaller file sizes why aren't all images

42
00:03:06,879 --> 00:03:12,040
Vector great question because vector

43
00:03:10,200 --> 00:03:17,519
graphics are defined by lines and polygons they don't have as much

44
00:03:14,640 --> 00:03:22,680
granularity as raster images which Define Graphics pixel by pixel meaning

45
00:03:20,159 --> 00:03:27,680
that vector graphics at least currently aren't usually a great choice for photos

46
00:03:25,840 --> 00:03:32,319
and other images that are designed to look photorealistic and while there are

47
00:03:30,000 --> 00:03:37,879
tools that can vectorize traditional raster images they tend to lose detail

48
00:03:35,480 --> 00:03:43,319
during this process because the computer has to guess at how to convert the

49
00:03:40,439 --> 00:03:46,439
patterns of pixels into lines and shapes and it's very easy to see the problems

50
00:03:45,280 --> 00:03:51,680
with this if you've ever tried to convert something like a photo of a

51
00:03:48,599 --> 00:03:54,560
person to vector and because modern

52
00:03:51,680 --> 00:03:59,959
screens are raster displays since they're just large arrays of individual

53
00:03:56,760 --> 00:04:01,680
pixels Vector images need to be rastered

54
00:03:59,959 --> 00:04:06,480
ized before they can be displayed properly anyway with lots of modern

55
00:04:04,239 --> 00:04:11,519
software only having partial support for rasterizing vector graphics think about

56
00:04:09,000 --> 00:04:16,680
how you can't resize svgs in Google Chrome for example so they're a good

57
00:04:13,959 --> 00:04:20,919
option for graphic designers and visual artists trying to design cool looking

58
00:04:18,799 --> 00:04:25,560
logos or some such but if you were hoping to upscale all your porn to 8K

59
00:04:23,440 --> 00:04:31,080
using vectors then you've got another thing coming shout out to Pearl Auto for

60
00:04:28,800 --> 00:04:34,960
supporting our Channel pearl auto makes a set of rear view cameras that fit

61
00:04:32,960 --> 00:04:39,320
around your license plate and sync with your smartphone they're quick and easy

62
00:04:37,039 --> 00:04:43,039
to install you only need a screwdriver to mount a camera frame on your license

63
00:04:41,080 --> 00:04:47,080
plate then you just plug in the adapter to your onboard diagnostic port and

64
00:04:45,120 --> 00:04:51,120
mount your phone to your dash you can actually operate it with an app that's

65
00:04:48,720 --> 00:04:56,320
already available for iOS and Android the camera frame has two HD cameras

66
00:04:53,680 --> 00:05:00,080
which give audio and visual alerts to warn you of obstacles in your way

67
00:04:58,240 --> 00:05:05,120
allowing you to switch between normal and wide-angle lenses and even see

68
00:05:02,320 --> 00:05:10,400
around corners in day or night it works on any car has a solar powered panel so

69
00:05:08,120 --> 00:05:14,639
it stays charged on its own it uses Bluetooth technology to connect to your

70
00:05:12,199 --> 00:05:19,080
camera without wires and the Pearl app will automatically update to add

71
00:05:16,400 --> 00:05:23,080
additional features soon rear view cameras will be mandatory on all new

72
00:05:21,000 --> 00:05:27,120
cars in the US not because it's like a fancy pants feature but because it

73
00:05:24,919 --> 00:05:31,440
legitimately improves the safety of the vehicle's operation and pearl auto has a
