By linking other compositions with your working version, you can create a more complex composition. You can link to as many
compositions as you need. You can link to a specific output of a composition, as well as specify the mark in, mark out and
offset times, and the repeat mode.
When you link to a composition, you are by default linking to the primary version which is read-only. The Link Image tab in
the tool UI displays all the outputs associated with the version to which you are linking. When you attempt to link to a composition
that is outdated, the link node turns red to indicate that it is out of date.
There are many advantages to linking compositions:
- Keeps the tool pipelines of individual compositions separate from each other. You see only your own tool pipeline. This eliminates
the risk of inadvertently deleting or modifying tools added to the pipeline by another composition and can also make it easier
to identify the different segments in the production pipeline.
- Makes it easy to review different possibilities for a shot. You can link to a composition and then choose the output you want
to see.
- Linking makes dependencies easy and efficient. If your work depends on the result of another composition, you can link to
that composition and work on the composition that contains the link. However, you may be working on multiple compositions
independently and each one will stay up-to-date or will detect if a more recent version is available. This is controlled by
the Link type list in the link node UI which lets you specify: primary, latest, working and explicit. For example, when linking
to the Latest version, the link node will realize if it is outdated with respect to this selection. How the link node reacts
to this out-of-date condition is controlled by the On Load button. When it's on, the link node will update to the proper version
at load time (when the composition is open in read-only). When On Load is off, it is up to you to visit the link node and
click the Update To button to link to the proper version.
- Makes it easy to apply your tool pipeline to a different rendered result. You just select the result.
