Most web video players and platforms allow you to upload a caption file in their specified format along with your video file. Captions will sync with your video. Users can turn captions on and off by clicking a \u201cCC\u201d button and can often change the visual formatting of the captions directly on the video player.<br \/><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-27777 alignleft\" src=\"https:\/\/www.3playmedia.com\/wp-content\/uploads\/2022\/08\/numbertwo.jpg\" sizes=\"auto, (max-width: 64px) 100vw, 64px\" srcset=\"https:\/\/www.3playmedia.com\/wp-content\/uploads\/2022\/08\/numbertwo.jpg 200w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2022\/08\/numbertwo-150x150.jpg 150w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2022\/08\/numbertwo-75x75.jpg 75w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2022\/08\/numbertwo.jpg 165w, https:\/\/www.3playmedia.com\/wp-content\/uploads\/2022\/08\/numbertwo-174x174.jpg 174w\" alt=\"number two icon\" width=\"64\" height=\"64\" \/><\/p>\n<h3><strong>Add Open Captions<\/strong><\/h3>\n<p>If you want to play your video offline or never want captions turned off, you can burn the captions directly onto the video file to create<strong> <a href=\"https:\/\/www.3playmedia.com\/services-features\/tools\/open-captioning\/\" target=\"_blank\" rel=\"noopener noreferrer\">open captions<\/a><\/strong>.

This is often necessary for offline viewing, for kiosks, or if you don\u2019t have a video platform. You can also distribute caption-encoded videos as a single asset. Users will still be able to turn the captions on or off, and the captions should work across mobile devices.<\/p>\n<p style=\"text-align: center;\"><span class=\"su-highlight\" style=\"background: #deeff5; color: #000000;\">\u00a0<a href=\"https:\/\/go.3playmedia.com\/wp-captioning-basics\"><strong>Captioning Basics: A Free Guide<\/strong><\/a> \ud83d\udcdd\u00a0<\/span><\/p>\n<h2><strong>Why do captions matter?<\/strong><\/h2>\n<p>Closed captions provide a text alternative to relevant auditory information in a video. They originated as the outcome of an FCC mandate in the 1980s to accommodate D\/deaf and hard of hearing television viewers \u2013 because of this, captions are required to be time synchronized and include details like speaker identifications and <strong><a href=\"https:\/\/www.3playmedia.com\/blog\/why-captioning-non-speech-elements-matters-for-accuracy\/\" target=\"_blank\" rel=\"noopener\">relevant non-speech elements<\/a><\/strong>. Most businesses and organizations are now legally required to add captions to video content.<\/p>\n<p>But including closed captions is more than just legal best practice. For starters, it\u2019s the right thing to do! <a href=\"https:\/\/www.who.int\/news-room\/facts-in-pictures\/detail\/deafness#:~:text=There%20are%20466%20million%20people,rise%20to%20over%20900%20million.\" target=\"_blank\" rel=\"noopener\"><strong>Millions of people around the world experience disabling hearing loss<\/strong><\/a>, and including captions ensures that this audience has equal access to your organization\u2019s video content.<\/p>\n<p>However, the benefits of captioned content are not limited to individuals experiencing deafness or hearing loss. We\u2019ve published plenty of information on the business benefits of captioning and transcription, because they\u2019re powerful tools for expanding your audience and creating a better user experience. Captions can improve comprehension among viewers who speak English as a second language, and <a href=\"https:\/\/www.3playmedia.com\/blog\/8-benefits-of-transcribing-captioning-videos\/\" target=\"_blank\" rel=\"noopener\"><strong>have proven to play a significant role in increasing overall audience engagement<\/strong><\/a>, comprehension, and information retention.<\/p>\n<p>This can translate to better brand awareness and expanded reach \u2013 but in order to reap the benefits and make a positive impact on your video\u2019s performance, it\u2019s crucial to build an accurate and efficient captioning workflow. <a href=\"https:\/\/www.3playmedia.com\/services\/integrations\/\" target=\"_blank\" rel=\"noopener\"><strong>3Play offers captioning workflow integrations<\/strong><\/a> with most popular video platforms and players, so we can work where you already do.<\/p>\n<h2><strong>What caption format do I need?<\/strong><\/h2>\n<p>It is critical that you use the correct caption format for your video player, video platform, or lecture capture system. While some caption formats are easier to create from scratch (for example, SRT and WebVTT), many formats use hex codes and are extremely difficult to create from scratch. We recommend using a <a href=\"https:\/\/www.3playmedia.com\/services\/captioning\/\"><strong>professional captioning service <\/strong><\/a>or a<strong> <a href=\"https:\/\/go.3playmedia.com\/captions-format-converter\/\" target=\"_blank\" rel=\"noopener noreferrer\">caption format converter<\/a> <\/strong>for these.<\/p>\n<p>Below, you\u2019ll find a list of major video players, video platforms, and lecture capture systems and the caption format that each requires.
