Adding captions to your videos is an excellent way to improve the accessibility of your courses. You can add captions in your native language to make your content accessible to students with hearing impairment and you can even open up your business to new markets by adding captions in other languages!

From your Video Library, you can easily upload closed caption files (SRT files) for the videos that you have hosted with Thinkific. Read on for more information!

Managing Your Captions


Creating SRT Files

First, you'll need to have your subtitles in SRT file format. You can create these files yourself (please follow Wistia's instructions for that). Or, save yourself some time and hire an experienced freelancer to do it for you (e.g. via Upwork).

 Here's a screenshot of an example SRT file, to give you an idea of the formatting you're looking for.

Note: You can upload multiple SRT files to the same video, meaning that you can add captions in as many languages as you like!

Uploading SRT Files

Once you have your SRTs, find the file you'd like to add captions to in your library and select Edit.


Note: The search bar will make it easier to find the right video if you have lots of files.

Navigate to the Closed Captions tab and hit Upload.

Follow the on-screen instructions to select the correct SRT file(s), then hit Upload

You'll be prompted to select which language the file is for from a drop-down list. The language you choose will be what's displayed to the user when selecting to switch on the captions. 

Once you've done that, select Save New Captions and that's it!

Your captions will now be available as an option when the student selects the CC icon on the video player to switch on subtitles.


Note: You can also select to auto-show closed captions. When enabled, this means your closed captions will be turned on by default for the viewer. Additionally, we'll check their browser settings and, if they have a language chosen that matches one of your available closed caption files, we'll show them that language by default. This is especially useful if you're expecting that a large number of your users will need closed captions enabled, making life easier for your students!


Managing Your Captions

Now that you have closed caption files added to your video, you might want to update or remove them. That's no problem at all!

Downloading Caption Files

Use this to option to download an SRT file that you previously uploaded. This makes it easy to perform quick edits to your existing files and reupload without needing to wonder where you saved them last time.

Deleting Caption Files

If you don't want to keep an old closed caption file, you can delete it. This will make sure that this file no longer shows up as an option to your video viewers. Click on the three dots you see next to the Download option and you'll see the option to delete appear. 

Happy captioning! And check out the Related Articles section below for other ways to customize your videos on Thinkific.


If you have any errors when uploading, try removing any spaces included in the filename (this sometimes can cause an error). If the issue continues, please reach out to us here with your srt file attached as well as the name of the video you are uploading to.
