00:00:00.199 --> 00:00:09.120
you know how in movies some important person can just walk into a room wave

00:00:06.080 --> 00:00:11.880
their hand say and hands and they get

00:00:09.120 --> 00:00:16.680
like this super detailed closeup of the drug kingpin's nose hair or whatever

00:00:14.679 --> 00:00:21.119
well for most of us the experience of trying to enlarge a photo more often

00:00:19.160 --> 00:00:25.960
results in a blur that looks like a smear of melted rainbow ice cream now

00:00:24.160 --> 00:00:30.640
we've tried to solve this problem in recent years with digital cameras that

00:00:28.279 --> 00:00:35.000
capture images with ever higher pixel counts as well as more powerful

00:00:32.960 --> 00:00:39.440
computers that can process these images more easily but what if that's not good

00:00:37.520 --> 00:00:44.120
enough and you want something that will still look good when it's blown up to

00:00:41.360 --> 00:00:48.680
the size of Kim Kardashian's Caboose well this is where vector graphics can

00:00:46.399 --> 00:00:54.960
be extremely helpful since they can be rescaled to be as big or as small as

00:00:52.039 --> 00:01:00.519
you'd like without any loss of quality but how is that even possible well you

00:00:57.359 --> 00:01:03.440
see the reason that traditional raster

00:01:00.519 --> 00:01:10.159
images tend to blur and distort when you resize them is because the image file

00:01:06.479 --> 00:01:13.159
itself it's like a JPEG or a PNG is

00:01:10.159 --> 00:01:15.680
really just a collection of instructions

00:01:13.159 --> 00:01:20.880
that tell the computer how many pixels there are what color they should be and

00:01:18.320 --> 00:01:26.240
where they go so if you take a lower resolution JPEG and try to stretch it

00:01:23.759 --> 00:01:31.840
out Beyond how many pixels are actually defined in the file the computer has to

00:01:28.880 --> 00:01:37.560
just guess at what the other pixels in the enlarged image would be a very

00:01:35.040 --> 00:01:45.000
imperfect science that might be okay for something like blowing up a 4x6 to a 5x7

00:01:41.439 --> 00:01:47.000
for the wall but can result in horrible

00:01:45.000 --> 00:01:52.439
looking enlargements and the bigger you go the worse it gets vector graphics on

00:01:50.280 --> 00:01:57.799
the other hand work in a fundamentally different way instead of telling a

00:01:54.680 --> 00:02:01.000
computer what pixel goes where Vector

00:01:57.799 --> 00:02:04.079
files Define images using lines and

00:02:01.000 --> 00:02:07.119
shapes and their positions relative to

00:02:04.079 --> 00:02:10.239
each other for example the file might

00:02:07.119 --> 00:02:12.680
tell the computer I want a line here a

00:02:10.239 --> 00:02:18.080
triangle here and a curve that bends exactly like this in some other place

00:02:16.040 --> 00:02:23.920
the computer can then render these instructions into a nice looking smooth

00:02:21.160 --> 00:02:29.080
lined image each time you enlarge or Shrink it a little like a graphics card

00:02:26.680 --> 00:02:34.160
can render a frame of a video game in any resolution you choose providing your

00:02:31.800 --> 00:02:39.720
video card can handle it from a set of instructions specifying where things

00:02:36.680 --> 00:02:41.800
like polygons should go and because

00:02:39.720 --> 00:02:46.840
these instructions remain exactly the same no matter how large or small the

00:02:44.159 --> 00:02:51.120
image ends up being Vector files have the significant advantage of taking up

00:02:49.080 --> 00:02:55.519
the same amount of space on your computer's drive so you can end up with

00:02:53.400 --> 00:03:00.720
an image large enough to look crisp on a highway billboard while still taking up

00:02:57.840 --> 00:03:06.879
less than a megabyte well G Linus that sounds fantastic with better quality and

00:03:03.840 --> 00:03:10.200
smaller file sizes why aren't all images

00:03:06.879 --> 00:03:12.040
Vector great question because vector

00:03:10.200 --> 00:03:17.519
graphics are defined by lines and polygons they don't have as much

00:03:14.640 --> 00:03:22.680
granularity as raster images which Define Graphics pixel by pixel meaning

00:03:20.159 --> 00:03:27.680
that vector graphics at least currently aren't usually a great choice for photos

00:03:25.840 --> 00:03:32.319
and other images that are designed to look photorealistic and while there are

00:03:30.000 --> 00:03:37.879
tools that can vectorize traditional raster images they tend to lose detail

00:03:35.480 --> 00:03:43.319
during this process because the computer has to guess at how to convert the

00:03:40.439 --> 00:03:46.439
patterns of pixels into lines and shapes and it's very easy to see the problems

00:03:45.280 --> 00:03:51.680
with this if you've ever tried to convert something like a photo of a

00:03:48.599 --> 00:03:54.560
person to vector and because modern

00:03:51.680 --> 00:03:59.959
screens are raster displays since they're just large arrays of individual

00:03:56.760 --> 00:04:01.680
pixels Vector images need to be rastered

00:03:59.959 --> 00:04:06.480
ized before they can be displayed properly anyway with lots of modern

00:04:04.239 --> 00:04:11.519
software only having partial support for rasterizing vector graphics think about

00:04:09.000 --> 00:04:16.680
how you can't resize svgs in Google Chrome for example so they're a good

00:04:13.959 --> 00:04:20.919
option for graphic designers and visual artists trying to design cool looking

00:04:18.799 --> 00:04:25.560
logos or some such but if you were hoping to upscale all your porn to 8K

00:04:23.440 --> 00:04:31.080
using vectors then you've got another thing coming shout out to Pearl Auto for

00:04:28.800 --> 00:04:34.960
supporting our Channel pearl auto makes a set of rear view cameras that fit

00:04:32.960 --> 00:04:39.320
around your license plate and sync with your smartphone they're quick and easy

00:04:37.039 --> 00:04:43.039
to install you only need a screwdriver to mount a camera frame on your license

00:04:41.080 --> 00:04:47.080
plate then you just plug in the adapter to your onboard diagnostic port and

00:04:45.120 --> 00:04:51.120
mount your phone to your dash you can actually operate it with an app that's

00:04:48.720 --> 00:04:56.320
already available for iOS and Android the camera frame has two HD cameras

00:04:53.680 --> 00:05:00.080
which give audio and visual alerts to warn you of obstacles in your way

00:04:58.240 --> 00:05:05.120
allowing you to switch between normal and wide-angle lenses and even see

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

00:05:08.120 --> 00:05:14.639
it stays charged on its own it uses Bluetooth technology to connect to your

00:05:12.199 --> 00:05:19.080
camera without wires and the Pearl app will automatically update to add

00:05:16.400 --> 00:05:23.080
additional features soon rear view cameras will be mandatory on all new

00:05:21.000 --> 00:05:27.120
cars in the US not because it's like a fancy pants feature but because it

00:05:24.919 --> 00:05:31.440
legitimately improves the safety of the vehicle's operation and pearl auto has a
