Old network
As of Houdini 20.5, use Copernicus nodes instead of Compositing nodes. Though both networks still exist, the Compositing network is now designated as COP Network - Old. The Compositing network and its nodes will be deprecated and then removed in a future Houdini release.
Metadata applied to an image sequence can be read via the copmeta or copmetas expression functions in other parameters. Metadata can be in a variety of different formats, such as scalar float, vectors, matrices, and strings. Metadata cannot be animated. Metadata is created and accessed by name.
