00:00:06.512 --> 00:00:08.527
In this video, we will show you

2
00:00:08.527 --> 00:00:11.479
how to add a video to a PowerPoint slide

3
00:00:11.620 --> 00:00:13.635
and how to add a caption file to it.

4
00:00:15.040 --> 00:00:17.992
I've got my slide ready and in a folder,

5
00:00:17.992 --> 00:00:23.709
I have an MP4 video file and a VTT
caption file.

6
00:00:24.271 --> 00:00:27.129
Before we start, let's just have a quick
look at the caption file.

7
00:00:27.691 --> 00:00:29.753
I've opened it in Notepad.

8
00:00:32.002 --> 00:00:35.376
So a caption file will have the captions

9
00:00:36.172 --> 00:00:40.952
and the timings of when that caption
should appear on the video,

10
00:00:40.952 --> 00:00:42.264
and it's set out like this.

11
00:00:42.264 --> 00:00:44.279
It's just a text file.

12
00:00:44.279 --> 00:00:45.778
There's lots of different formats.

13
00:00:45.778 --> 00:00:47.652
If you don't have a VTT

14
00:00:47.652 --> 00:00:49.995
format, you'll need to change it.

15
00:00:49.995 --> 00:00:54.212
So you can use any number of free online
converter tools

16
00:00:54.212 --> 00:00:59.928
to convert, for example, SRT
or any other subtitle file to VTT.

17
00:01:01.147 --> 00:01:04.286
For your PowerPoint slide,
you will need VTT.

18
00:01:04.895 --> 00:01:06.957
So let's go to the Insert menu

19
00:01:08.035 --> 00:01:10.190
and I am going to insert a video

20
00:01:10.190 --> 00:01:12.439
from this device.

21
00:01:13.048 --> 00:01:14.922
Now in my folder

22
00:01:14.922 --> 00:01:18.811
I have two files, but when I go to import

23
00:01:18.858 --> 00:01:22.513
only the video file will be there
because I'm inserting a video file.

24
00:01:22.982 --> 00:01:25.418
I'm going to insert that video.

25
00:01:27.480 --> 00:01:30.853
I can move that around, I can resize it

26
00:01:31.275 --> 00:01:34.133
and I can do any other formatting
I want to.

27
00:01:35.258 --> 00:01:37.601
I'm going to go to the video format menu

28
00:01:37.976 --> 00:01:40.506
and I'm going to add some alt text.

29
00:01:42.708 --> 00:01:45.894
The alt text is
just a brief text description

30
00:01:46.035 --> 00:01:50.627
so that a screen reader user
knows what this item is on the page.

31
00:01:52.314 --> 00:01:56.249
I'm going to type in a
video to show how to produce

32
00:01:57.889 --> 00:02:00.420
lists in PowerPoint,

33
00:02:02.856 --> 00:02:04.402
and then I can close that.

34
00:02:05.012 --> 00:02:08.151
Now I'm going to the Playback menu

35
00:02:08.151 --> 00:02:11.384
and the last icon says insert captions.

36
00:02:11.712 --> 00:02:14.008
So I'm going to insert captions.

37
00:02:16.257 --> 00:02:19.256
I'm going to locate my VTT file

38
00:02:19.256 --> 00:02:21.177
that goes with this video.

39
00:02:21.177 --> 00:02:22.817
I'm going to insert that.

40
00:02:25.066 --> 00:02:28.393
And now I have the option to show

41
00:02:28.393 --> 00:02:30.829
and hide audio and subtitles menu.

42
00:02:31.673 --> 00:02:36.733
When I click on the captions menu,
my caption file PP dash

43
00:02:36.733 --> 00:02:39.545
lists is now highlighted there.

44
00:02:42.356 --> 00:02:45.027
I might want to just test
that that is working

45
00:02:51.446 --> 00:02:53.133
and that looks to be fine.

46
00:02:53.133 --> 00:02:57.959
I would probably, in a real life situation,
go through and watch it from end to end,

47
00:02:58.053 --> 00:03:01.754
to make sure that the captions match up
correctly and that they're all accurate.

48
00:03:02.176 --> 00:03:06.627
However,
that is how you add a video with alt text

49
00:03:06.627 --> 00:03:09.439
and a caption
file to your PowerPoint slide.
