Hello,I need to get the source width and height of a selected timeline clip to accurately calculate anchor points.Here is what I have tried: Downcasting: Retrieved the ProjectItem base item from the clip and cast it using ppro.ProjectItem.cast(baseItem) to a ClipProjectItem. Checking child objects: * clipProjectItem.getMedia() only exposes start and duration. clipProjectItem.getFootageInterpretation() exposes frame rate and PAR, but no resolution. Metadata: Parsing ppro.Metadata.getProjectMetadata() streams is failing to capture the properties. What is the officially supported UXP method to extract the asset pixel dimensions of a source item?

Hello,

I need to get the source width and height of a selected timeline clip to accurately calculate anchor points.

Here is what I have tried:

Downcasting: Retrieved the ProjectItem base item from the clip and cast it using ppro.ProjectItem.cast(baseItem) to a ClipProjectItem.
Checking child objects: * clipProjectItem.getMedia() only exposes start and duration. clipProjectItem.getFootageInterpretation() exposes frame rate and PAR, but no resolution.
Metadata: Parsing ppro.Metadata.getProjectMetadata() streams is failing to capture the properties.

What is the officially supported UXP method to extract the asset pixel dimensions of a source item?

Correct answer Inspiring_Smile6C2C

Tinkered around a little more with this. Was able to get the dimensions for all footage types using ppro.Metadata.getProjectColumnsMetadata();

Thank you so much for pointing me the correct direction!

You were close!

The dimensions of projectItems (at least, those that have dimensions) are available in the item’s XMP metadata:

ppro.Metadata.getXMPMetadata()

Many thanks! I got a really comprehensive output for .mp4 videos. Adding a snippet here.

However, it gave an output like this for a .mov file. Still not able to find the height/width of this video.
