Create Panel in Premiere Pro that performs the same action as a script

Report · Oct 14, 2016

So I've looked at several examples for Premiere Pro panels, but I'm still somewhat confused. Let's say I have the following HTML file:

<!DOCTYPE html>

<html>

<head>

<title>MyTest</title>

</head>

<body>

<button onclick="myFunction()">Replace Media (BCV)</button>

</body>

</html>

This creates a button that I can load into a Premiere Pro panel. I also have the following code that runs in Premiere just fine when I activate it from ExtendScript:

var BCV_File_Suffix = ["(PREV).psd", "(BACK).mxf", "(BATT).mxf", "1(NARR)_Fixed.flac", "2(NARR)_Fixed.flac"];

for (j = 0; j <= 4; j++)

{

for (i = 0; i <= app.project.rootItem.children.numItems; i++)

{

var BCVchild = app.project.rootItem.children;

if (!BCVchild) continue;

var mediaPath = BCVchild.getMediaPath();

if (mediaPath && mediaPath.length > 0 && mediaPath.indexOf(BCV_File_Suffix) > -1)

{

var BCVpath = (app.project.path).toString().replace(/\\/g, '\\').replace('\\\\?\\','').replace('(PROJ).prproj',BCV_File_Suffix)

app.project.rootItem.children.changeMediaPath(BCVpath);

app.project.rootItem.children.name = app.project.name.replace('(PROJ).prproj',BCV_File_Suffix)

}

What do I need to change in the HTML file to get the button to activate the script in Premiere Pro? I'm confused.

Hi John,

You will need to use the CSInterface class provided by Adobe. The CEP Cookbook demonstrates this, located at this URL CEP-Resources/CEP_6.x at master · Adobe-CEP/CEP-Resources · GitHub

First, download a copy of CSInterface from the URL above. Place it in your extension folder and include it in your HTML.

In your ExtendScript JSX file, wrap the logic in a function, e.g.:

function myBcvFunction() {
var BCV_File_Suffix = ["(PREV).psd", "(BACK).mxf", "(BATT).mxf", "1(NARR)_Fixed.flac", "2(NARR)_Fixed.flac"];
for (j = 0; j <= 4; j++)
{
for (i = 0; i <= app.project.rootItem.children.numItems; i++)
{
    var BCVchild = app.project.rootItem.children;
    if (!BCVchild) continue;
    var mediaPath = BCVchild.getMediaPath();
    if (mediaPath && mediaPath.length > 0 && mediaPath.indexOf(BCV_File_Suffix) > -1)
    {
        var BCVpath = (app.project.path).toString().replace(/\\/g, '\\').replace('\\\\?\\','').replace('(PROJ).prproj',BCV_File_Suffix)
        app.project.rootItem.children.changeMediaPath(BCVpath);
        app.project.rootItem.children.name = app.project.name.replace('(PROJ).prproj',BCV_File_Suffix)
    }
}
}
}

Then add the following JavaScript to your panel (not ExtendScript):

var script = "myBcvFunction()";
CSInterface.evalScript(script, evalScriptCallback);

You also need to make sure that the JSX file is referenced from the <ScriptPath> element in the panel extension's manifest.xml, like this:

<DispatchInfoList>
  <Extension Id="com.YourPanel">
  <DispatchInfo >
  <Resources>
  <MainPath>./index.html</MainPath>
  <ScriptPath>./YourScriptFile.jsx</ScriptPath>
  </Resources>
  ...
  </DispatchInfo>
  </Extension>
  </DispatchInfoList>
