Often, the most efficient way to create audio description tracks is to outsource the process to a vendor who provides audio description services. However, this is not an option for everyone due to common barriers such as cost or lack of budget. You can create audio description tracks yourself. If you need help <a href=\"https:\/\/www.w3.org\/WAI\/media\/av\/description\/#tips-for-doing-description-yourself\" target=\"_blank\" rel=\"noopener\">creating audio description yourself<\/a>, W3C offers some great tips.<\/p>\n<p>Whether you outsource your audio description to a vendor or create your own, finding a workable solution to publish audio descriptions and make them available to all viewers can be a challenge in itself.<\/p>\n<p><a href=\"https:\/\/www.w3.org\/WAI\/media\/av\/description\/\" target=\"_blank\" rel=\"noopener noreferrer\">The World Wide Web Consortium (W3C)<\/a>, an international community that develops Web standards, lists several <em>sufficient techniques<\/em> for publishing description to audio-visual material. All of these methods are reliable ways to meet the <a href=\"https:\/\/www.w3.org\/TR\/WCAG21\/#audio-description-or-media-alternative-prerecorded\" target=\"_blank\" rel=\"noopener noreferrer\">WCAG 2.1 audio description success criteria<\/a>.<\/p>\n<h3>1. Secondary AD Track (with Compatible Video Players)<\/h3>\n<p>Adding a secondary, user-selectable soundtrack is a user-friendly option. It allows viewers to toggle between the original soundtrack (without AD) and a secondary version of the soundtrack (with AD).<\/p>\n<p>The option to publish a secondary audio description track is highly dependent on media player capabilities since most devices or video players can\u2019t merge multiple soundtracks.<\/p>\n<p>&nbsp;<\/p>\n<p><span class=\"su-highlight\" style=\"background:#DEEFF5;color:#000000\">&nbsp;<a href=\"https:\/\/www.3playmedia.com\/blog\/the-best-online-video-players-for-audio-description\/\" target=\"_blank\" rel=\"noopener noreferrer\"><u>The Best Online Video Players for Audio Description<\/u><\/a> \u27a1\ufe0f&nbsp;<\/span>&nbsp;<\/p>\n<p>For example, a viewer comes across a video file with two audio tracks, one with audio description. They can choose one of the two audio tracks in the media player, either without audio description. The secondary soundtrack may merge the original soundtrack with the audio description track. However, when using a platform that can simultaneously play two audio tracks, a secondary audio track containing just the description is sufficient. The latter option is the optimal user experience because it gives the user a choice to toggle audio description, just like closed captions.<\/p>\n<h3>2. Seperate Video with Audio Description<\/h3>\n<p>This approach adds the audio description to synchronized media by utilizing a second version of the movie where the original soundtrack and additional audio description merge into a single track.<\/p>\n<p>In this case, the description is added to the original soundtrack during already-occurring pauses in dialogue and sound effects, ensuring that the description doesn&#8217;t obscure original content. This method would require creating and publishing two versions of the same content, one with audio description and one without it.<\/p>\n<p>For example, if you needed to publish a described recording of a music concert: The first version would include the music solely. In contrast, the second version would consist of both the music and narration describing the actions of the performers on stage.<\/p>\n<div style=\"background-color: #deeff5;padding: 30px;margin: 20px 0 20px 20px !important;width: 250px;float: right;text-align: left\">\n<h4><strong>Are You New to Audio Description?<\/strong><\/h4>\n<p>&#8220;A Beginner&#8217;s Complete Guide to Audio Description&#8221; is a free resource is designed to serve as your comprehensive guide to all things audio description, including how to add audio description to videos.<\/p>\n<p><a href=\"https:\/\/go.3playmedia.com\/wp-adguide\" target=\"_blank\" rel=\"noopener noreferrer\">Read the White Paper<\/a><\/p>\n<\/div>\n<h3>3. Extended Audio Description<\/h3>\n<p>This approach is similar to the one above in that you would publish two versions of the same video. The difference, however, is that the second version would provide <strong>extended audio descriptions<\/strong>.<\/p>\n<p>One of the main obstacles in creating audio description is trying to fit a vast amount of narrative information into a brief window of time (such as during natural pauses in dialogue). However, with extended description, the video momentarily pauses to allow more time for descriptions when needed. For extended AD, provide a version of the movie with extended audio descriptions and a version without description. Depending on your video player capabilities, publish the content so that audio descriptions can be turned on and off (refer to option one above).<\/p>\n<h3>4. Text-Based Audio Description<\/h3>\n<p>This method is considered an alternative to audio description and is better-suited for media that doesn\u2019t have important time-based information in the media\u2019s original video portion. For example, this technique would be sufficient for \u201ctalking head\u201d videos such as a press conference or lecture where an individual speaks in front of a static background without critical visual elements to describe. This technique is not suitable for a situation where there are several speakers and where the identity of the speakers is not made clear in the audio track.<\/p>\n<h3>5. Integrated Descriptions at the Time of Recording<\/h3>\n<p>Integrating descriptions is a more proactive approach to publishing audio description and doesn\u2019t work for all scenarios. If you\u2019re in the process of creating or recording a new video, this method involves writing or including descriptions in the script that describe all relevant visual information.<\/p>\n<p>This method works well if a speaker is recording a presentation with a slide deck. For instance, if the slide deck contains critical visual information, such as a statistical graph, the speaker can describe the graph in detail during the recording.<\/p>\n<h3>6. WebVTT Description Track<\/h3>\n<p>This method is an advisory technique, as currently there isn&#8217;t enough user agent support. This method may not be the ideal way to provide audio description. However, it may be appropriate when other methods are not possible or available to the publisher.<\/p>\n<p>HTML5 video allows for the use of a WebVTT description file. This file would be included as a <code><\/code> element with the <code><\/code> &#8220;description.&#8221; Screen readers should be able to read this file to provide descriptions to users. However, this functionality has minimal support across video players and is an imperfect method. Therefore, WebVTT description tracks may not be the best primary method for publishing audio descriptions.<\/p>\n<p>&nbsp;<\/p>\n<p><span class=\"su-highlight\" style=\"background:#DEEFF5;color:#000000\">&nbsp;<a href=\"https:\/\/www.3playmedia.com\/blog\/how-to-create-a-webvtt-file\/\" target=\"_blank\" rel=\"noopener noreferrer\"><u>How to Create a WebVTT Description Track<\/u><\/a> \u27a1\ufe0f&nbsp;<\/span>&nbsp;<\/p>\n<h2>Audio Description Output Formats<\/h2>\n<p>If you utilize an audio description service, they may provide different audio description output formats.<\/p>\n<p>Using the 3Play Media account system, you can instantly download your audio description files once they have been processed.
