Question

Export Metadata from MXF Files

  • June 30, 2019

I have a directory with 281 MXF files in it, not all of which are the same duration.  Is it possible to somehow create a text file that is essentially a table of the metadata of these files using Premiere Pro, or by scripting in Premiere?  Essentially, I'm wanting some way to obtain the information displayed in list view:

in a parsable, plain-text format. I am primarily interested in obtaining the "Meda Duration" column (with the associated filepath as the key), but it would be nice if I could get the other metadata as well.

Is this possible with a Premiere Pro script, or within Premiere directly?  If so, can you give an example of how to do it?  Thanks!

In Avid you can export an ALE file from a bin, not sure if similar exists in PP

Yes, using the XMP External Object, more details in the PPRO Sample Panel. Here's an example of how I get projectItem duration in one of my extensions:

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);
        }
// usage
getPrMetadata(thisItem, ["Column.Intrinsic.MediaDuration"])

Thank you, this is helpful.  However, what exactly is the "kPProPrivateProjectMetadataURI" variable?  It seems like it's a link to something.  When I attempt to put that link in my web browser, it just gives me a "this site cannot be reached" error.

It’s just the unique XML Namespace uri for Adobe’s XMP metadata, not a functioning website.
