Mediasite Editor 5.5

Mediasite Editor by Sonic Foundry is a non-linear, timeline-based tool for polishing Mediasite presentations captured from lectures, webinars, and training sessions. Designed to work seamlessly with the Mediasite Video Platform, it lets you refine multi‑source recordings—such as camera, screen, and slides—without re-uploading large files or losing the original content.

Key capabilities

• Trim starts and ends and remove unwanted segments to tighten recordings
• Synchronize, replace, or reorder slides to match the spoken narrative
• Add chapter markers and thumbnails to improve navigation and search
• Update titles, descriptions, and other metadata for clarity and consistency
• Review and manage captions and timing files (when available from your workflow)
• Save edits non-destructively, version content, and republish directly to Mediasite

How it works

• Check out a presentation from your Mediasite library, make edits on a visual timeline, then commit changes back to the server.
• Edits are stored as instructions, enabling quick publishing and preserving the source media.

Who it’s for

• Instructors, trainers, and communications teams who need a fast, reliable way to clean up recordings, correct timing, and enhance viewer experience across an organization’s Mediasite environment.
