Synthesia automatically creates a version each time you generate a video. This versioning system allows you to track changes, revert to previous versions, and maintain consistency across edits.
How are versions created?
Synthesia generates and saves a new version of your video each time you select Generate.
Generating a video creates a version
When you generate a video for the first time, Synthesia saves it as a version.
This version captures the exact state of your video, including all elements, animations, and script details.
Editing and re-generating creates a new version
If you make changes to the video — for example, modifying the script, adjusting animations, or changing the avatar — and generate it again, Synthesia saves a new version.
When editing a video with multiple versions, you will always work on the most recent draft version, even if it has not been generated yet.
Reverting to an older version
If you need to edit an older version, you can either Duplicate it or Restore it from the video Version History.
Check out Restoring & Duplicating – Versioning Documentation to learn more.
Publishing, sharing, and embedding videos with multiple versions
When your video has multiple versions, only one version is visible externally at any time.
How do published versions work?
If your video has multiple versions, only the published version will be accessible via:
Share page
Embed link
SCORM export
Synthesia keeps older versions in the Version History, but external viewers cannot access them.
To update a published video with a new version
Navigate to your desired version in the Version History.
Select Reshare, then choose Replace.
The share page, embed links, and SCORM exports will automatically update to reflect the latest published version — no need to replace links manually.
