YouTube

To ensure that your YouTube videos are as accessible as possible, use the following best practices.

Manually edit auto-generated captions.

YouTube automatically generates captions based on its best guess at interpreting the audio.  Understandably, it is not 100% accurate.  Using auto-generated captions saves time, and manually editing the captions ensures that users with disabilities have access to all the video’s information. Learn more about YouTube captions below.

Edit the embed options.

Some features, like showing suggested videos when the video finishes, are difficult for assistive technology users to navigate. Follow the steps below to edit embed options.

Edit the embed code.

A few minor adjustments, like changing the default video player to HTML5, make your video display as accessibly as possible on your page.  Follow the steps below to edit the embed code.

Captions

YouTube can use speech recognition technology to automatically create captions for your videos.  Automatic captions may not be ready at the time that you upload a video. Processing time depends on the complexity of the video's audio.

Keep in mind that if you use auto-generated captions, you will need to revise them for accuracy.

You can also add captions by uploading a caption file to your video. These types of files contain both the text and time codes for when each line of text should be displayed.

Finally, you can transcribe your video and YouTube will automatically line up your text with the speech in the video. You will need to set the timing to sync with your video.

To add YouTube automatically generated captions, use the following steps:

  1. Upload your video to YouTube.
  2. Click on the link of the video to which you would like to add captions.
  3. When the video page appears, click on the Edit Video button.

  8. Edit your captions.  Remember, auto-generated captions are only 70-85% accurate, and the industry standard calls for 99% accuracy or higher.  You will need to edit punctuation, spelling, and speaker changes.

  8. Because there are some situations where Internet Explorer and Firefox will still fail to load the HTML5 player, add these instructions, in a small type size: “For a fully keyboard-accessible alternative to this video, view it in Chrome or on any Android or iOS device. You can also view it in Firefox with the YouTube ALL HTML5 add-on installed, or disable Flash in Internet Explorer."
