Closed captioning can be added to your video by creating a “timed text” file. The most common one is a .VTT file. Many video programs come with the capability to create and embed them. You will need to look at your video programs options to figure out if it can do it or not. If you use a professional videographer, check with them on their ability to do them.
A timed text file indicates the timing on each video screen of people talking and what they are saying. If it is just music, it will indicate that as well. Each line is a new video screen. Here is an example of what a timed text file looks like:
1
00:00:00,506 –> 00:00:09,546
[ Music ]
2
00:00:10,046 –> 00:00:11,896

When a .VTT file is added to your video, it will play at the bottom of the screen. You can either embed it when you create your video or send the file to us and we will attach it to your video. When we attach it, there will be a black bar under the video where the captioning will show up. The user also has the opportunity to turn off the closed captioning by clicking on the CC icon when watching the video. If you embed it yourself, they will not have the option to turn it off.
If you don’t have a video program that can create the .VTT file for you, there are some services that can be found by doing an internet search. Some are free and others have a fee. If you choose to use one of them, do a test one first to see how it looks.
Lastly, if you don’t want to create a timed text file or send it out to have it done, you can create a PDF of the script and it can be uploaded to your Management Console. You will then either add it to your page using the document drop down menu or embed it as a hyperlink. If you do use the PDF, make sure you add to your content that there is a PDF of the script and whether they click on the document icon or the hyperlink to read it.
