Benefits of Adding Online Subtitles

The aim of online subtitling? To keep viewers engaged in video content. There is currently a growing need for video content to come equipped with subtitles, providing accessibility for sensory impaired communities, foreign viewers and more. Online subtitles are used for various reasons which include:

  • Ensuring sensory impaired (deaf or hard of hearing) viewer accessibility
  • Providing translations for foreign viewers
  • Serving as an aid when viewing content remotely in public or noisy environments
  • SEO (search engine optimisation) opportunities
  • Extra learning opportunities where a video is jargon or information rich

Subtitle Technical Information 

When considering subtitle formats, it is important to make a distinction between closed captioning and subtitles. Closed captioning is a service aimed at providing onscreen text to aid deaf and hearing-impaired viewers. Captions can be open or closed (meaning burned onto a video or saved as a text file which can be turned on or off). 

Subtitles on the other hand appear usually as white text within a black box at the bottom of the screen. When it comes to broadcast or video, subtitles are actually similar to open captions in terms of they are burned onto the screen effectively as an image and are not removable. For online subtitles, however, this is not usually the case. When uploading subtitle files for use online, it’s preferable to retain the text format of the file to retain searchability and SEO benefits. For online subtitles, the formats commonly used can be very different to broadcast, and the most common are below.

Different subtitle formats and extensions are required for different media players on the internet.

Summary of Online Subtitle Formats

The three most common types are .SRT, .WebVTT and SAMI (SMI), but there are a host of others out there too. 

  • .SRT files originated from DVD ripping software and are the most commonly used subtitle format for online videos, including use with YouTube and Facebook
  • .WebVTT (Web Video Text Track) encompasses all media players embedded within HTML5 websites. HTML5 is the latest standard for browsers to display and interact with web browsers. .WebVTT is fast becoming more popular due to its extra formatting options as compared to .SRT.
  • SAMI (SMI) format is used for Windows media player. The SAMI format was developed by Microsoft and stands for ‘Synchronized Accessible Media Interchange’.

Subtitle Categories

There are many different ways to categories subtitles. Subtitles could be mandatory (forced) in which case they cannot be turned off or they can be optional, in which case the viewer can choose whether to turn them on or off depending on personal preference.

Subtitles can also be hard coded or saved as separate streams of information added onto the video at a later stage, depending on whether they are encoded into the original video or added at a later stage into the container.

So there you have it, everything you need to know to create great online subtitles for your clients or customers. If you would like more information on how Capital Captions can help your company grow in the online world of subtitles, contact us at or Get a Quote.
