Automation & Workflows with Zapier
Updated over a week ago

Please note: This feature is in beta and should be considered experimental.


What is it and who is it for?

A faster way to add captions to your videos in bulk. This is meant for professional editors who add captions to and edit hundreds of videos per week.

How does it work?

The setup takes about 5 minutes:

Once setup is complete, simply upload videos to the input folder, and they'll automatically get captioned and added to the output folder.

What can it do?

Captions can be added to:

  • Videos up to 5 minutes long

  • Videos in English

  • Vertical videos only (horizontal videos will be rescaled to vertical)

How can I give feedback or get help?

Please join our Discord and share your thoughts in the #zapier-beta-testing channel.
