RevBlogResourcesWhat is an SRT File? How to Create & Use SRT Files

An SRT file or SubRip (.srt) file is one of the most common types of raw closed caption file formats or subtitle formats. Typically a raw file like an SRT or another type of supported “closed caption file” is ordered after a video has been produced as part of the post-production process. The raw caption file can be uploaded to the platform where the video will be hosted as a separate sidecar file, in addition to the actual video itself.

Most platforms today support caption sidecar files, including Facebook, Vimeo, YouTube, and most of the other major players in the video hosting world. Before long, we expect that other social media and video player platforms that have been slower to adopt will follow the big guys making it easier to upload closed captions as a file extension to a video file.

What is an SRT file?

Familiar with closed captions but not SRT files? They’re not so different. SRT files are what make it possible to add closed captions or subtitles to video content after it is produced. But unless you’ve worked on video marketing, a video post-production team, or run a very successful YouTube channel, you probably haven’t had to think too much about caption file formats. As video has grown more popular, however, it’s becoming common practice to add closed captions to support video content wherever it’s hosted. The trend toward captioning video content has a ton of benefits for video producers and viewers alike. Think increased views, accessibility, and overall viewer experience.

What Other Types of Closed Caption File Formats Are Common?

SRT files are not the only type of closed caption file format, but it is one of the more widely supported types. Other types of closed caption file formats include Scenarist (.scc), Timed Text (.ttml), Quicktime Timed Text (.qt.txt), Transcript (.txt), WebVTT(.vtt), DFXP (.dfxp), Cheetah .CAP (.cap), MacCaption (.mcc), Spruce Subtitle File (.stl), Avid DS Subtitle File, Facebook ready SubRip (a type of .srt file specifically for adding captions to Facebook videos), and Avid DVD Subtitle File.
