Introducing Caption Import: A New Feature for Existing Captions and Subtitles

We’re excited to announce a new feature! Caption Import is designed for people who already have captions but need a place to store them. Besides storage, there are a number of other reasons why you might be interested in Caption Import, which we will go over below.

Reasons to Use Caption Import

Some of the benefits of storing your captions with 3Play Media include:

Conversion and Compatibility

Using Caption Import will allow you to convert your caption files into over 50 different output formats. You can even change the SMPTE frame rate and starting time code, if you need to! What this means is that you can make the captions you already have compatible for any application.

Searchable Video

All of our tools and plugins are available to customers through Caption Import. This means that you will have access to our interactive transcript, which makes your videos searchable.

Captions Editor

With Caption Import, you will have access to our captions editor, where you can make edits to your existing captions and translations. When you finalize the file, any edits you make will propagate to all output files (including all caption formats and video plugins) without having to reprocess.

Edit your existing captions and transcripts

Asset Management

Caption Import allows you to securely manage your caption files within the 3Play Media account system.


Once you’ve imported your captions, you can submit captions for translation into multilingual subtitles. Or, if you have subtitles in another language, you can translate those into English!

How It Works

You can currently import both captions and subtitles with Caption Import. The formats accepted are: SRT, DFXP, WebVTT, SCC, STL, SMI, CAP, QuickText, and SBV. Once imported, you will have access to our full range of caption output formats, which includes over 50 different options.

Note that caption import is a monthly subscription based on the number of imported files stored in your account. For complete details on caption import pricing, see the price list. Once you have your subscription set up, you can import your captions via the 3Play Media account system, via FTP, or via API.

The Caption Import tool requires that you have captions or subtitles with time codes. If you have transcripts but not captions, you should use our automated transcript alignment service, which will create caption files from your transcripts and provide you with access to all of the same tools listed above.
