Make Your Video or Audio More Accessible

Not everyone can understand your native language or accent. In fact, only a quarter of the total world population can read and speak standard English. With this in mind, it's vital to caption your video to reach a wider audience. Most people who can't understand your language will tune in because you can translate the narrations into something understandable. Additionally, in the noisy world, to visualize your audio for more attention, subtitling a video is a good way!

Auto Captioning for Lengthy Video Tutorials

Vimeo, Dailymotion, and other platforms are home to millions of how-to tutorials. These videos can be as short as 2 minutes and as long as several hours. In a typical scenario, you'll spend hours captioning a 1-hour video. You might even hire someone to do it for you. So, instead of wasting time and resources, use Media.io Auto Subtitle Generator to add subtitles to video quickly and easily. The AI system will do all the dirty work.

Edit the Auto Generated Subtitles to Streamline Essentials

Auto-generating subtitles is undoubtedly good. However, sometimes you may need to edit the subtitle texts and tracks to make them more engaging and beautiful. For example, you may want to resize, reposition, or change the text opacity to make them unobtrusive. You can also beautify the text with a new font style or color. Just be mindful not to overdo it. A good auto-subtitle should maintain its originality.

Increased Viewer Engagement

Do you love watching movies and videos with subtitles? You're not alone! Research shows that most people love watching subtitled films. And yes, this also includes native speakers of the movie language. Often, you'll find yourself too immersed in reading the subtitle headlines than even watching the movie characters themselves. So, use automatic subtitles to make the movie more entertaining to watch.
