16 May 2026 - 8.53.0 - Mediasite Video Platform

Mediasite Video Platform (MVP) 8.53 introduces a transcript view in the caption editor. Additionally, several bug fixes are included in the release.

New Features

Transcript View for Simplified Caption Review

Mediasite now includes a new transcript view within the Caption Editor, making it easier for users to review and correct captions in a more natural reading format. Designed with workflows like student worker caption review in mind, the transcript view presents captions as continuous text while remaining synchronized to the video timeline.

Key benefits include:

  • Easier proofreading and editing of captions in a readable transcript format
  • Simplified identification and correction of transcription errors
  • Quick navigation between transcript text and corresponding video timestamps
  • Improved efficiency for accessibility review and caption remediation workflow

Users can switch between traditional timed captions and the new Transcript View directly within the Caption Editor.

Live captions from third party services can now be written to the database for instant on demand.
