Using automated captioning

Use Mediasite Captioning to submit captioning requests through captioning services using credentials for an existing account. Mediasite includes its own captioning service, Mediasite Captioning Powered by Vidable™ and has built-in support for multiple partner captioning services.

Overview

There is a three-step process for setting up and using automated captioning using Mediasite Captioning or a partner captioning service. If you are using a non-partner captioning service, there is an additional step:

Step 1: Add an audio transcription template (non-partner captioning services only)

If you are using a non-partner captioning service, you must add an audio transcription template for it. Mediasite has pre-defined audio transcription templates for Mediasite Captioning Powered by Vidable™ and its partner captioning services: 3Play Media, AI Media, Amberscript, Automatic Sync Technologies, Cielo 24, IBM Watson Speech to Text captioning, and Verbit.

Step 2: Add an audio transcription profile

When you add an audio transcription profile, you will select an audio transcription template and provide credentials and other information used to access your account. Mediasite encrypts this information in the database and never shares it.  Information in the provider profile is used only for submitting captioning jobs for billing purposes and querying the status of captioning items.

When Mediasite submits media files for captioning, it uses the audio transcription profile to access your account.  Mediasite then uploads media files along with a manifest describing the captioning job to your captioning provider. The captioning provider then captions the media and posts a VTT, DFXP, SRT, or SMI file back to Mediasite.

For IBM’s Speech to Text service, Mediasite sends audio directly to IBM and the service then processes and returns the results in a DFXP file in approximately half the length of the presentation’s runtime.

Step 3: Enable automated captioning on folder, presentation, template, or schedule

When you add “audio transcriptions” delivery on a folder, presentation, schedule, or template you are enabling the automated captioning feature on them. You must select an existing audio transcription profile or add a new one when enabling this feature.
