Synthesia automatically creates a version of your video each time it is generated. This versioning system lets you track who generated each version, restore previous states, and keep published videos up to date without changing their share links.
How versions are 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.
How published versions work
If your video has multiple versions, only the published version is accessible via:
Share page
Embed link
SCORM export
Older versions remain in version history but are not visible externally.
How to update a published video with a new version
To replace a published version with a newer one:
Navigate to the version you want to publish in version history.
Select Reshare, then select Replace.
The share page, embed links, and SCORM exports automatically update to reflect the new version — no need to replace links manually.
✍️ The share link URL does not change when you replace a published version. Any links you have already sent to viewers will continue to work and will automatically show the updated video.
💬FAQs
Why does Reshare still show an older version of my video?
Why does Reshare still show an older version of my video?
Reshare only shows generated versions. If your latest edits have not been generated yet, they will not appear as an option. Generate the video first, then return to Reshare and select Replace to update the published version.
Why can't I see the Replace option when I select Reshare?
Why can't I see the Replace option when I select Reshare?
The Replace option only appears when a previous version has already been published. If your video has not been shared before, you will see Share options instead of Replace. If you have previously shared the video but Replace is not appearing, try refreshing your browser. If the issue continues, contact the Synthesia support team.
Can I see who was editing or who generated each version?
Can I see who was editing or who generated each version?
Version history shows which collaborators were editing at the time a snapshot was auto-saved, or who generated each version. It does not log who made which specific edits within a version.
