Clear CRS Metadata

It appears that Bridge’s edit menu > Develop Settings > Clear do not remove Camera Raw Settings metadata that is baked into a JPEG file.

One can remove all XMP metadata, however that is a little extreme, it should be possible to target only the CRS metadata and clear it, leaving all other metadata intact (this is possible using ExifTool)…

I had a go at hacking an existing script, however it does not work. I’m sure that I’m missing something simple! Can anybody please help?

// https://forums.adobe.com/thread/290238
#target bridge // let EntendScript know what app the script is for
clearCRS.execute = function(){// create a method for that object
  var sels = app.document.selections;// store the array of selected files
  for (var i = 0; i < sels.length; i++){//loop though that array
    var md = sels.synchronousMetadata;// get the metadata for the file
     md.namespace = "http://ns.adobe.com/camera-raw-settings/1.0/";// set the namespace
     md.crs = " ";//set the porperty
  }
}
// this script only works in bridge
if (BridgeTalk.appName == "bridge"){
  //creage the munuItem
  var menu = MenuElement.create( "command", "Clear CRS in metadata", "at the end of Tools");
  menu.onSelect = clearCRS.execute;
}

Correct answer SuperMerlin

Here you go Stephen...

#target bridge   
if( BridgeTalk.appName == "bridge" ) {  
remCRS = new MenuElement("command", "Remove Camera Raw Metadata",  "at the end of Tools");
}
remCRS.onSelect = function () {
if (ExternalObject.AdobeXMPScript == undefined) ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");
var sels = app.document.selections;
for (var a in sels){
var thumb = new  Thumbnail(app.document.selections);
var md = thumb.synchronousMetadata; 
var xmp = new XMPMeta(md.serialize());
        if(thumb.hasMetadata){
         XMPUtils.removeProperties(xmp, XMPConst.NS_CAMERA_RAW, "", XMPConst.REMOVE_ALL_PROPERTIES);
        var updatedPacket = xmp.serialize(XMPConst.SERIALIZE_OMIT_PACKET_WRAPPER | XMPConst.SERIALIZE_USE_COMPACT_FORMAT);
        thumb.metadata = new Metadata(updatedPacket);
        }
    }
};

    Thank you SuperMerlin!

    I was thinking that perhaps line 18 in the hacked script was incorrect, however as you re-wrote the entire code I now suspect that I was way out of my depth!

    For future reference, the ExifTool code to remove Camera Raw Settings metadata is:

    Mac OS:

    exiftool -r -XMP-crs:all= 'os-path/to/file/or folder'

    Win OS:

    exiftool -r -XMP-crs:all= "os-path\to\file\or folder"
