Captioning is one of the most important workflows of the video editing process. Ensuring your video is accessible for all, and that it can be enjoyed and understood regardless of where your audience is, is essential. Captioning and subtitling your videos can have a huge effect on their success.
Know your formats: The key to successful subtitling
Getting to grips with caption formats might seem a bit daunting since it’s one of the more technical aspects of video editing, but once you know which file formats are the best fit for your preferred video platform and how these file formats are created and used, you’ll save huge amounts of time in your video editing workflow.
Simply speaking, subtitles are stored a little differently depending on the file format, and different software play different types of subtitles. There are a few different file formats you can use; and it’s easy to get to know which formats you’ll need to create.
Let’s take a closer look at some of the commonly used subtitling file formats. All of these can be easily created from Trint transcripts:
You might be saying, "Hold on, this isn't a subtitle format!" You're right. But when used with Trint’s extension for Adobe® Premiere® Pro CC, EDL (Edit Decision List) files are your new secret video editing weapon.
EDL is the most complex type of file in this list, so let’s break it down a little bit first. EDL is not technically a subtitle format in the same way that VTTs and SRTs operate: EDLs construct the framework for your subtitles and captions, saving you time by cutting your video for you.
EDL file format isn’t right for every video project, but it saves huge amounts of time by letting you choose the best parts of your video content from the transcript. No more scrubbing through hours of footage - just search your Trint, Highlight the important sections and export. Trint's extension for Premiere® will take care of cutting your video for you.
Here’s an example of an EDL workflow:
After transcribing your video with Trint and Highlighting the parts you want to keep, export just the Highlights as an EDL file
Import this EDL into Premiere®, then choose “Link Media” and locate the original file on your computer

Get ready to be wowed, and to save hours in your video editing: watch as Premiere® automatically cuts the video for you. Magic!
To add captions, pop back to Trint and export the Highlights as an SRT file, then import into Premiere® and the captions will automatically align with your clips
SRT (SubRip Text Format)
SRT, which stands for SubRip Text Format, is the most well-known and popular file format for captions and subtitles. It’s widely used by YouTube and Facebook for their captions and subtitles. An SRT file contains the start and end time of the subtitle, along with the text it should display. It’s used by a lot of video players, so its popularity is unrivaled. It’s the queen of the subtitle formats.
VTT (Video Text Tracking)
Modelled on the hugely popular SRT file format, VTT (Video Text Tracking) uses more text formatting options such as pop-ups and other subtitling effects. As a more modern version of SRT with extended options, it’s a great choice for anyone who wants to customize their on-screen text. While it provides wider options for captioning and subtitling, it’s only compatible with videos on HTML5 media players and cloud-based video management systems.

Why are subtitles so important?
An estimated 466 million people worldwide have disabling hearing loss of some kind, from those who are hard of hearing to fully deaf. This makes up about 5% of the world, and if you don’t make sure your video content is subtitled you risk alienating this huge audience. The simple act of captioning and subtitling your videos makes them much more inclusive and boosts the number of people who will see your video.
Then there’s the portion of your audience who choose not to turn audio on. These people could be on busy commutes, in quiet zones or have audio issues with their device - whatever their reason, they won't hear the audio, which means you need to make sure they still know what's going on.
More people watch video without sound than you might think: 85% of video content on Facebook is viewed without sound, which is a staggering amount of video, considering over half a billion people are watching video content on Facebook every single day. That equals a minimum of 425 million videos.
These numbers make it clear: captions and subtitles are not an option, they’re a necessity.
Subtitling doesn’t have to be time consuming thanks to automated transcription services like Trint. Trint’s intelligent platform uses powerful artificial intelligence (AI) to transform the audio in your video into accurate, useful subtitles.
When it comes to your video project there are a whole host of options to explore; the video player you use will likely point you in the direction of the file format you’ll need. Trint supports the use of all three of the above file formats. We also make it easy to add captions and subtitles to video with our extension for Adobe® Premiere® Pro CC.
