Create panels for Premiere Pro

*Last updated April 2018, current released version = Premiere Pro 12.1, also known as "Premiere Pro CC 2018".

What's Possible

For the impatient, here are links to working sample code, showing what's possible for Premiere Pro panels:

Premiere Pro 12.1 : API Improvements

We've added many new capabilities for the 12.1 release. All of these are exercised in the PProPanel sample, available on GitHub.

Get and set the current Project panel selection

It's now possible for a panel to know which projectItems are selected, and to select projectItems as appropriate.

Consolidate and Transcode API

All functionality available from Premiere Pro's Project Manager dialog, is now available to panels.

Improved time resolution for trackItems

We now provide (and accept) time values for track items in ticks, eliminating an opportunity for rounding error.

Import and change Motion Graphics templates (.mogrts)

Panels can now insert .mogrt files into sequences, and change the parameters of those .mogrts as desired.

Forcibly replace footage

It's now possible to force Premiere Pro to update the path to a given projectItem, even if Premiere Pro doesn't think such a change is advisable.

Identify sequences

All projectItems now have an isSequence() method; this eliminates the need to compare a list of 'all project items' against a list of 'all sequences', to determine which projectItems are and are not sequences.

Set the frame rate for projectItems

Use the handy new setOverrideFramerate().

API Documentation

While the sample panel should continue to be your first option for working example code, Premiere Pro's ExtendScript API is documented here, to enable developer participation.

What was new in 12.0

  • We've extended our new, not-in-the-QE-DOM Source monitor object, to close the front-most or all open clips.

  • Change the Label assigned to projectItems.

  • Query PPro for the current insertion bin, the default target for items imported into the project (but not via drag). Previously, you could set, but not get, the insertion bin.

  • Import Compositions by name, from After Effects projects.

  • Open PPro's Events panel to see PProPanel's feedback; I've minimized modal alerts.

1. Obtain and install these

  • Creative Cloud. Use the Creative Cloud application to install Premiere Pro CC and other Adobe applications with which you'll be developing and testing, as well as ExtendScript Toolkit (available under 'previous versions').

  • The CEP Test Panel shows the full capabilities of CEP panels.

  • The PProPanel sample project is exhaustive in its exercise of Premiere Pro's ExtendScript API.

  • The ZXPSignCmd signing utility creates signed .zxp bundles for Add-Ons or direct distribution.

  • Use the ExManCmd command line utility to test .zxp installation.

2. Enable loading of unsigned panels

Note: Premiere Pro 12.0 has integrated CEP8, so even if you had unsigned panels loading before (using CEP6 or CEP7), you'll need to perform this step again, but for key CSXS.8.

On Mac, type the following into Terminal, then relaunch Finder (either via rebooting, or from the Force Quit dialog):

defaults write /Users/<username>/Library/Preferences/com.adobe.CSXS.8.plist PlayerDebugMode 1

On Windows, make the following registry entry (a new Key, of type String):

3. Put panel into extensions directory

Put /PProPanel or your own panel's containing directory here, to have Premiere Pro load it:

Windows:    C:\Program Files (x86)\Common Files\Adobe\CEP\extensions
Mac:        /Library/Application Support/Adobe/CEP/extensions

4. Write and test your panel's JavaScript using Chrome debugger

To enable debugging of panels using Chrome’s developer tools, put a file named .debug into your extension’s folder (as a peer of the /CSXS folder). The contents of the file should resemble the following (and the Extension ID must match the one in the panel's manifest):

<?xml version="1.0" encoding="UTF-8"?>
<ExtensionList>
    <Extension Id="com.example.PProPanel">
        <HostList>
            <Host Name="PPRO" Port="7777"/>
        </HostList>
    </Extension>
</ExtensionList>

When the panel is active, you can debug the panel in your web browser by browsing to localhost:7777, and selecting your panel:

Optional diagnostics: Turn on CEP logging. Find CEP logs (distinct from Premiere Pro's logs) here. Note that Mac Library path is the system's library, not the user's. Also, note that logging WILL impact performance.

Windows:    %\AppData\Local\Temp\csxs8-PPRO.log
Mac:        /Library/Logs/CSXS/csxs8-PPRO.log

Set logging level in Windows Registry (see above), or MacOS X .plist:

defaults write /Users/<username>/Library/Preferences/com.adobe.CSXS.7.plist LogLevel 6

5. Create your panel's ExtendScript using ExtendScript Toolkit (ESTK)

Launch ExtendScript Toolkit, select the correct version of Premiere Pro from the drop-down menu, then then click the chain link to connect.

Once in the session, you can hit breakpoints, and use ExtendScript Toolkit's Data Browser to view the ExtendScript DOM.

Here's a screen video showing how to debug panels at both the JavaScript and ExtendScript levels.

6. Package and deploy your panel

You can either generate a self-signed certificate (ZXPSignCmd will make them for you), or get one from a commercial security provider. Here's an example:

	./ZXPSignCmd -selfSignedCert US California Adobe "Bruce Bullis" password certificate.p12

To sign directory /PanelDir with certificate.p12, do the following:

    ./ZXPSignCmd -sign panelDir/ PanelName.zxp certificate.p12 password -tsa http://timestamp.digicert.com/

Submit your panel to the Adobe Add-Ons site for approval, and distribution. You can also directly supply the .zxp file enterprise customers, and those who do not connect their systems to the public internet, for installation using ExManCmd, the command line version of Extension Manager.

If you encounter any issues with the Add-Ons store or ExManCmd, please contact the Add-Ons team.
