For some clips, you may have to modify their clip history in Batch. This is the case for any clip that you created using more than one effect or operation. To gain access to the original sources and effects settings, you expand the clip into a Batch process tree.
Also, if you edited clips together, and at least one of the clips has uncommitted clip history, you can only access that clip's history using the Batch timeline. The clip history for a segment can also be expanded into a Batch process tree.
Some nodes in a clip history tree appear as blank nodes. These wildcard nodes represent an effect that was applied to a clip that does not have an equivalent Batch node (Warper, for example). They are named after the module used to create them. You can disconnect or connect these nodes, but you cannot modify their values. They contain frames rendered at their position in the process tree.
Because wildcard node frames are rendered, changes made upstream do not propagate downstream. If you need to make upstream changes, you will have to recreate the effect. To do so, you exit Batch and rebuild the effect in the module originally used to create it.
