Recall that in Autodesk Visual Effects and Finishing products, clips using soft-imported media contain only links to the media at its original location, so that no media is actually imported and duplicated in the Autodesk managed storage.
When importing a Wiretap timeline containing soft-imported media into Lustre, there is an additional advantage. Lustre recognizes the clips as soft-imports, and reads the associated media by way of the Wiretap Gateway server, allowing you to modify the associated input parameters. That is, you are not bound by the resolution used in the originating application, and can work in Lustre at the resolution of your choice.
For example, suppose a Smoke timeline contains soft-imported RED media at HD resolution. When importing the timeline into Lustre via Wiretap, the soft-imported media is accessed directly, via the Wiretap Gateway. You thus have access to all the RED transcoding options for the source material, and can work with it at any available resolution, such as SD, HD, 2K or higher.
