How to tell if item is Adjustment Layer

[Philip Bowser]

I'm creating an extension and I need to be able to tell the difference between Adjustment layers and Color Mattes in the project bin. They just show up as stills in their metadata. Is there a way to do this?

I was able to figure out when an item is a Title as the codec shows up as "Titl" even though the MediaType shows up as "Still Image". But the Adjustment layers codec gives me "RAW " which is the same as a regular still image.

Is there a method that I'm not aware of to determine an items type?

Any help is greatly appreciated!

Thanks

+1!

Same here, I've managed to infer a bunch of stuff from other properties.  Here's a test script I wrote, works best if you have test items in the project root:

function removeAllNamespace(xml)
{
          var ns =new Namespace();
          var d=xml.descendants();
          for (var i=0;i<d.length();i++)
        d.setNamespace(ns);
}
for(var c = 0; c < app.project.rootItem.children.numItems; c++) {
        var i = app.project.rootItem.children;
        $.writeln("======= " + i.name + "======= ");
        $.writeln("type: " + i.type);
        $.writeln("canChangeMediaPath: " + i.canChangeMediaPath());
        $.writeln("mediaPath: " + i.getMediaPath());
        var xmlRoot = new XML (i.getProjectMetadata());
        removeAllNamespace(xmlRoot);       
        $.writeln("XML Codec: " + xmlRoot.child(0).child(0).child("Column.PropertyText.Codec"));
        $.writeln("");
}

Here's the result with some test items of different types:

======= Bin======= 
type: 2
canChangeMediaPath: false
mediaPath: 
XML Codec: 
======= music_Adventurous_00_BREAK_00.wma======= 
type: 1
canChangeMediaPath: true
mediaPath: \\wexfile\evoke\Audio\ModularMusicEdits\Adventurous\00\wma\music_Adventurous_00_BREAK_00.wma
XML Codec: 
======= Sequence 01======= 
canChangeMediaPath: false
type: 1
mediaPath: 
XML Codec: 
======= IMG_20161227_141732.jpg======= 
type: 1
canChangeMediaPath: true
mediaPath: C:\Users\gemof\Downloads\IMG_20161227_141732.jpg
XML Codec: RAW 
======= Unity - DefaultScene_RecordTakes.unity - UnityProject_HCap - PC, Mac & Linux Standalone_ _DX11_ 4_27_2016 3_33_01 PM.mp4======= 
type: 1
canChangeMediaPath: true
mediaPath: \\wexfile\evoke\User\Geordie\Unity - DefaultScene_RecordTakes.unity - UnityProject_HCap - PC, Mac & Linux Standalone_ _DX11_ 4_27_2016 3_33_01 PM.mp4
XML Codec: H.264
======= Title 01======= 
type: 1
canChangeMediaPath: true
mediaPath: 
XML Codec: Titl
======= Color Matte======= 
type: 1
canChangeMediaPath: true
mediaPath: 
XML Codec: RAW 
======= Adjustment Layer======= 
type: 1
canChangeMediaPath: true
mediaPath: 
XML Codec: RAW 

I think the only thing you can't distinguished between here is a Color Matt and Adjustment Layer

Wow that's still a lot closer than I was. Thanks for this.

Also, I love this removeAllNamespace function you've created. My solution to this was definitely not as elegant.

Fingers crossed they put this info into the metadata!

Now, in the new decade of 2020, you can directly check if a trackItem is an adjustmentLayer:
