Creating videos at scale is one of the key benefits of Shotstack. In this tutorial we'll show you how to use merge fields to create videos from data.

Merge fields in Shotstack are like the mail-merge in an email campaign, allowing you to automate and personalise your video production. By replacing placeholders in your video templates with unique user data, you offer an engaging, tailored experience that boosts engagement.

You can declare merge fields in the Merge Fields dialog. Click on the Merge Fields button and add a merge field and placeholder value.

You can replace different properties in your template by replacing it with your merge fields.

You can replace text by wrapping your merge field in double curly braces. For example {{ TEXT_FIELD }} will be replaced with the value in your merge field.

You can replace other properties such as URLs by selecting these from the merge field dropdown next to the property you wish to replace.

By referencing your template ID and replacing your merge field values you can quickly create many iterations of your video.
