Caption Key: hand captions to editors as an alpha overlay
How to · Stop rebuilding captions in After Effects. Hand over a Caption Key.

- Captions
- Editors
- Caption Key
Every time captions are rebuilt by hand, you pay twice: once for AI/captions in create, again for someone to recreate them in the edit suite.
Why the usual approach fails
- Export a burned-in caption file and pray the editor can undo it
- Send a transcript and ask them to retime everything
- Rebuild caption styles from screenshots
- Skip captions in the handoff and lose accessibility
Burned-in captions lock the picture. Plain transcripts lose timing and style. Both create friction between marketing create and finishing editors.
A better system
The winning workflow is simple: make or upload your video → put it on a branded Share Page (your video + a next-step button) → if you have a list, give each person their own tracked link with a Campaign → see who watched → only send the next video to people who engaged, using a multi-step video sequence.
- Generate and style captions in Vyrol Studio
- Export Caption Key as an alpha overlay for the editor
- Keep transcript files when they need searchable text
- Your brand caption look travels with the handoff
- Publish a Share Page version for stakeholders who only need to watch
How to run it in Vyrol
- Finish captions and styles in Studio
- Export the Caption Key (alpha overlay) with your package
- Send the overlay + picture to your editor or agency
- Use the same master to publish a Share Page for client review
- Update the page if the finished edit replaces the draft later
What good looks like
- Caption Key is a first-class Studio output — not a hack
- Editors get timing + look without rebuilding from zero
- Transcript .txt / .json still available when text is the deliverable
- Stakeholders can review on a Share Page while finishing continues
Who this is for
In-house video teams and agencies who create in Vyrol and finish (or archive) in a traditional timeline tool.
Handoff should move work forward — not force someone to rebuild what you already paid to create.
