Use YouTube to create video captions

Published: April 8, 2022

Automatically generated captions

YouTube generates captions automatically for most videos. This is useful even if you are not using Youtube to serve them; you can download the resulting captions file to use on other video platforms. For example, if I want to share a video on Facebook or Twitter or transcribe an interview for an article.

And if you need to convert the captions file to another format there are plenty of websites that offer the service for free,

There are a couple of downsides:

  1. They are not generated instantly.
  2. They are never accurate because the captions are generated by machine-learning algorithms.

You will always need to check and edit the text that Youtube generates.

How to add captions to YouTube videos

  • Sign in to your YouTube channel and click on the ‘Manage Videos’ button.
  • Upload your video and fill in the basic meta-information, e.g. title, description, keywords, and so on.
  • Under More Options set your video language. It’s a good idea to change the visibility to private if you don’t want your video to go public without captions or with incomplete captions.
  • Publish your video.

You can now wait a few hours or a few days for Youtube to automatically create the captions for your video. Once your video captions are generated and edited for accuracy you are ready to make your videos public.

Manually add or edit captions

However, if you are impatient, you can also add and edit captions manually.

Add captions manually

  • When you are logged in select Subtitles from the left-hand menu (you might have to scroll the left-hand menu to find it).
  • Click on the video you have just uploaded or any video you want to add captions to.
  • If you have not already set the default language select your language from the drop-down menu.
  • Click Confirm.

Assuming captions have not already been generated you will be presented with a dialog box with three choices,

  • Upload a file i.e., an existing captions file.
  • Auto-sync. This allows you to edit existing text or copy and paste a transcript for YouTube to sync.
  • Type Manually, i.e., type in the speech in real-time as you watch the video).

I recommend you use the Auto-sync option.

To use Auto-sync – write out a full transcript of your video – ignoring any related time information. Then click the Auto-sync option and paste your text into the form field. Click Submit.

Youtube will then create the timings automatically – syncing your text with the audio of your video.

Writing out a transcript of the video in your favourite word processor is easier than typing the captions into the YouTube form as you watch the video. I’ve done that many times and it’s a taxing and time-consuming activity.

Editing captions

To edit your captions, click the Subtitles link from the left-hand menu and choose the video you would like to edit.

  • If you have added captions manually it will say, Edit.
  • If you have not added captions manually, the link will say Add.
    If captions have been generated automatically, you will have a link that says, DUPLICATE AND EDIT.
  • To add captions manually click the Add link. To edit manually created text click the Edit link, to edit the automated captions click DUPLICATE AND EDIT.

Edit automatically created captions

To edit the automatically added captions click DUPLICATE AND EDIT and a new editable copy will be created.

Then click the Edit link for the copy of the published captions text.

YouTube is not good at adding proper punctuation and capitalisation of words – so be sure to look for those issues.

Download the resulting captions file

To download the captions file click on the three dots to the right of the EDIT AS TEXT link within the captions dialog and choose Download subtitles.

By default, it downloads the captions in .sbv format (it does for me – but check if that’s the case for you). Use a conversion service such as the one provided by Arizona State University to convert the file to .srt.

If you Google for .sbv to .srt conversion you will find several websites that will cover the file for free.

Zoom video conferencing and accessibility

Published: December 7, 2021

Zoom was created in 2011 but it didn’t take off until its use during the pandemic – when it became the de facto video chat tool. There can be no doubt that it’s a powerful and valuable communication tool, however, it also has some major accessibility issues. In this short article I set out what some of those issues are and suggest ways to get around them – where possible.
For example, Zoom doesn’t always work well with screen reading software.

  • Users are not alerted to new chat activity. It can be difficult to copy and paste URLs from the chat. And the audio can cut out if the screen reader user switches between chat and video.
  • There are issues with screen sharing. The Share Screen function in Zoom is only screen-reader-accessible to the individual sharing their screen.
  • There are issues with closed captioning.
  • The Whiteboard function in Zoom is not accessible. Using the whiteboard is equivalent to posting an image to the screen – however, the image does not have a text description.

Chat functionality

If you are going to be using the chat function you can use a ‘chat wrangler’, i.e., a person who monitors the chat, tells the group of new messages, and reads them out. Or you can separate out the chat and use an accessible chat application instead of the one built-in to Zoom.

Any important information, such as links should be sent to participants by email after conclusion of the session.

Accessible chat applications :

Keyboard navigation issues with Zoom desktop application

The Whiteboard function in Zoom is not accessible to screen reader uses – as it is the equivalent to posting an image to the screen – but it is an image without a text description.

If you intend to use the whiteboard – be sure to make the whiteboard content available in an alternative accessible format.

If you are using the whiteboard – ensure you are keeping screen reader users up to speed with what you are doing and what you are writing on the board.

Share screen functionality

The Share Screen function in Zoom is only screen-reader-accessible to the individual sharing their screen. If the session is going to involved screen sharing then seek out an alternative to Zoom for the session. There is a list of the most accessible video chat software at, the Big Hack website.

The Polling tool

The Zoom polling tool also has accessibility issues for presenters and participants with some impairments (as reported on Yale University accessibility page). As with the chat example above, you could look at using a third-party tool instead. For example, Mentimeter have a polling tool; they write about inclusivity in their accessibility statement – which suggests that it’s accessible. However, I’ve never used it, so check it out first.

Survey tools are necessarily the same as online poll tools but they might be worth checking out to see if they suit your purposes. The University Of Washington’s has a review of online survey tools. And I see SurveyMonkey has information about how you can make their surveys accessible – so that may also be worth investigating.
