These instructions explain how to develop UXP plugins within Premiere Pro. [As of August 2025, only Premiere Pro BETA builds support UXP plugins.]

The Premiere Pro UXP API documentation is available here: https://developer.adobe.com/premiere-pro/uxp/.

Things you will need

• Premiere Pro BETA build, available through Creative Cloud Desktop.
• UXP Developer Tool, also available for download through Creative Cloud Desktop.
• Adobe third-party sample panel - premiere-api directory from this Git repository.

Build the sample

• Open your console / terminal / command prompt, into sample-panels/premiere-api/html.
• Install dependencies with npm i
• Bulid the project with npm run build

The plugin is now built in the /build-html directory.

Display the sample

• Launch Premiere Pro Beta.
• Load UDT. On first launch it will be blank.
• Click Add Plugin.
• Navigate to the premiere-api/build-html/manifest.json, and click Open.

The UXP sample plugin displays in Premiere Pro Beta:

Adding TypeScript Definitions in Visual Studio Code

To see definitions, add typescript definitions to the .js file in which you are working.

Copy types.d.ts to the root of the /html directory.

Add this line to the top of index.js:

/// <reference path="./types.d.ts" />

You can now see and use TypeScript definitions for Premiere Pro's UXP APIs, in Visual Studio Code.

Transcript definition

We have included Premiere Pro's transcript JSON definition, in the assets directory, within the premiere-api sample plugin.
