ExtendScript: Identifying Images in Premiere

[avartation]

Is there a way to check if the project item is an image or a video ?

• type attribute only seperates video and audio
• isSequence() seperates sequences from videos.

Is there something similar for seperating images from videos ?

Thanks !

There isn't.

Theres no direct method, but you can try to infer it by considering how different media types will be handled by different methods eg calling canProxy() on Video/Movie clips will return true ... but on Stills will return false.

It's a bit complicated, but you can through project item metadata.

function getPrMetadata(projectItem, fieldNames) {
    var kPProPrivateProjectMetadataURI = "http://ns.adobe.com/premierePrivateProjectMetaData/1.0/";
    if (app.isDocumentOpen()) {
        if (projectItem) {
            if (ExternalObject.AdobeXMPScript === undefined)
                ExternalObject.AdobeXMPScript = new ExternalObject('lib:AdobeXMPScript');
            if (ExternalObject.AdobeXMPScript !== undefined) {
                var retArray = []
                var retArray2 = []
                var projectMetadata = projectItem.getProjectMetadata();
                var xmp = new XMPMeta(projectMetadata);

                for (var pc = 0; pc < fieldNames.length; pc++) {
                    if (xmp.doesPropertyExist(kPProPrivateProjectMetadataURI, fieldNames[pc])) {
                        retArray.push([fieldNames[pc], xmp.getProperty(kPProPrivateProjectMetadataURI, fieldNames[pc])])
                        retArray2.push([xmp.getProperty(kPProPrivateProjectMetadataURI, fieldNames[pc])])
                    }
                }
                return (retArray2);
            }
        }
    }
    return (false);
}

var media = app.project.rootItem.children[0];
getPrMetadata(media, ['Column.Intrinsic.MediaType']);

 Images will return "Still Image" and videos will return "Video", however, be aware that this is language-dependent on the user's app locale.
