00:00:00,330 --> 00:00:06,900
Now,  first thing's first, we're going to need a newspaper to project AR content onto.
1

2
00:00:06,900 --> 00:00:09,750
Now, if you have a copy of newspaper that's lying around,
2

3
00:00:09,750 --> 00:00:17,070
then, of course, you can use that. But you will need to find a main image in the newspaper and you need
3

4
00:00:17,070 --> 00:00:24,300
to be able to source the actual image online somewhere, and you'll also need to find a video that's relevant
4

5
00:00:24,300 --> 00:00:26,550
to that content to make it work.
5

6
00:00:26,580 --> 00:00:29,750
So it might be a little bit roundabout.
6

7
00:00:30,030 --> 00:00:35,790
So for those of you guys who are following along with the tutorials, I've included a link in the course
7

8
00:00:35,790 --> 00:00:42,590
resources list that downloads a copy of the front page of the Daily Prophet,
8

9
00:00:42,660 --> 00:00:48,330
so the Harry Potter newspaper, and we're going to be working with this in the tutorial and I'll show
9

10
00:00:48,330 --> 00:00:51,180
you how to source all of the content and materials.
10

11
00:00:51,180 --> 00:00:57,450
So I recommend that if you're working along with the tutorial, just to simply head over here and download
11

12
00:00:57,720 --> 00:01:00,550
this newspaper, and then print it out.
12

13
00:01:00,570 --> 00:01:06,450
So we're going to be holding this newspaper in one hand and the app and the other in order to launch
13

14
00:01:06,690 --> 00:01:13,210
our newspaper into AR. Once you've gotten hold of this newspaper,
14

15
00:01:13,220 --> 00:01:16,670
we need a saved copy of the actual image.
15

16
00:01:16,700 --> 00:01:24,740
So go ahead and open it up in preview and expand the image to as large as possible on your screen, and
16

17
00:01:24,740 --> 00:01:31,610
then hold down command + control + shift, and 4, and that opens up our screenshot tool which we're going to
17

18
00:01:31,610 --> 00:01:36,200
use to take a screenshot of this main image.
18

19
00:01:36,200 --> 00:01:40,970
Now, once we let go, a copy of that screenshot is saved on our clipboard.
19

20
00:01:41,150 --> 00:01:47,660
And if you're inside the preview application, if you hold down control + N, then it will create a new
20

21
00:01:47,660 --> 00:01:52,110
file from that screenshot which we can now save,
21

22
00:01:52,280 --> 00:01:57,530
and I'm going to call it just harrypotter, and I'm going to save it in the PNG format.
22

23
00:01:58,310 --> 00:02:04,340
So, now make sure you can locate that Harry Potter image and make sure you've already printed out your
23

24
00:02:04,340 --> 00:02:05,680
newspaper image.
24

25
00:02:05,750 --> 00:02:08,290
The next step is sourcing our video.
25

26
00:02:08,390 --> 00:02:12,780
Now, ideally, you would have some video that's lying around that you own,
26

27
00:02:12,770 --> 00:02:15,520
that's also in the MP4 format.
27

28
00:02:15,530 --> 00:02:19,700
It's really important that you try to find a video that's in the MP4 format.
28

29
00:02:19,700 --> 00:02:25,530
It works best from a lot of experimentation with ARKit and with SceneKit.
29

30
00:02:25,550 --> 00:02:33,950
Now, if you can't find anything that's suitable, then the easiest thing is just  to head on to YouTube and
30

31
00:02:34,010 --> 00:02:36,260
try to find a Harry Potter clip,
31

32
00:02:39,650 --> 00:02:42,360
and this should give you something that's relatively short,
32

33
00:02:42,390 --> 00:02:44,760
sort of two or three minutes long.
33

34
00:02:44,760 --> 00:02:50,370
And we're going to copy this YouTube URL and head over to a YouTube downloader.
34

35
00:02:50,370 --> 00:02:55,740
Now, of course, if you're building your app for launch on the App Store, then you need to make sure that
35

36
00:02:55,740 --> 00:03:00,750
you own all of the media and all of the content that you're going to put into your app.
36

37
00:03:01,050 --> 00:03:09,120
But just for the purposes of learning and education, we're going to download this YouTube video in an
37

38
00:03:09,120 --> 00:03:10,160
MP4 format.
38

39
00:03:10,260 --> 00:03:13,830
So I'm going to select the MP4 360,
39

40
00:03:13,830 --> 00:03:15,600
so make it a little bit smaller,
40

41
00:03:16,130 --> 00:03:18,900
and then I'm going to download this video.
41

42
00:03:18,900 --> 00:03:25,710
Now, once we've downloaded the video, it's important that you rename it to the exact same name that you
42

43
00:03:25,710 --> 00:03:27,150
gave your main image.
43

44
00:03:27,150 --> 00:03:28,830
So I called the other one Harry Potter,
44

45
00:03:28,830 --> 00:03:31,630
so I'm going to call this one harrypotter as well.
45

46
00:03:31,770 --> 00:03:37,260
And we now have an image that we've printed out which we're going to launch our ARKit on.
46

47
00:03:37,260 --> 00:03:40,590
We have the image that needs to be recognized in the newspaper
47

48
00:03:40,590 --> 00:03:45,510
and we've also got the video that needs to play in the place of the image
48

49
00:03:45,600 --> 00:03:48,630
once the ARKit app recognizes it.
49

50
00:03:48,630 --> 00:03:54,360
So we're now all ready with our resources to get started building our app.
50

51
00:03:54,360 --> 00:04:00,120
Once you've done all of that, then head over to the next lesson and let's get started building our magical
51

52
00:04:00,120 --> 00:04:01,050
newspaper app.
