Hey everybody. Josh here with Online ADA.

In this video we're gonna cover article 1.2.3

of the WCAG accessibility

guidelines.

This article is audio descriptions or media

alternatives for pre recorded content.

This is going to be a level A

compliant article and

let's jump right in.

An alternative for time based media or audio

description of the pre recorded video content is

provided for synchronized media, except when the

media is media alternative

for text and it's clearly labeled as such. Just

like always, they're basically saying here that

you don't have to

provide an audio description for audio

descriptions.

You don't have to provide text alternatives for

content that is a text alternative.

There's no need to be redundant there, you just

have to clearly label it as such so that people

understand what it's there for.

This is an interesting article because they're

actually

providing two options for how to meet compliance.

Number one,

you can do a text transcript. This is going to be

a complete

text version of everything that happens in the

video,

including dialogue, scene changes,

any like logos that appear.

Anytime someone does anything it's

it is basically a screenplay or a book.

It reads

like that.

You can even

see, like, actor one and, like, their name colon and

then like, in quotes the dialogue that they say,

and then like the next line.

It is just like a screenplay.

This is probably the best way to meet compliance.

This is the best option here because

you are not constrained by time.

Whereas the alternative of the text transcript

is the audio description.

The audio description

is basically some narrator who's going to be

describing what's happening on the scene, in real

time, as the video is playing,

but they only do it during pauses in dialogue,

which adds a constraint.

It's not a bad thing by any means, and in fact

audio description is one of the requirements for

moving up in compliance to level

AA,

which is in a different article,

but it is important to know that a lot of the

1.2 guidelines overlap a little bit

and that's because WCAG wants to give you a few

different options on how to meet compliance because,

I mean let's face it,

for providing this content for your videos is

time consuming and it's difficult. It's not an

easy process.

It's

honestly best, if you're producing your own

content, you're keeping accessibility in mind

and if you are doing that then,

you know a lot of times an audio description may

not even be necessary.

But it is still important to have some

alternative for this content

because people have all sorts of different

disabilities

and you wanna make sure you're

being accessible to as many audiences as you can.

So

text alternative is the text transcript. Audio

description, that's gonna be a narrator reading

out loud.

There's a really good example that is

on the WCAG official documentation site. They

have an authoring back best practices. I

definitely advise that you go check that out

and you can just even Google

'what's the difference between a text transcript

closed captions and subtitles'.

An audio description is in there somewhere. If you

Google that, you'll come across the

article that has the example of the Universal

logo, circling around the world with the

sun raising behind it and then you've got the

gold letters that kind of circle around the globe.

It's a really cool audio and it gives you really

clear idea of

what this

guideline is trying to achieve.

So,

thank you for joining me on this video

and I'm Josh with Online ADA, and we'll see you in the

next video.
