Abstract
In a distributed network, a method of recursively linking a multiply modified multimedia asset to an original digital negative of the multimedia asset is disclosed. The original digital negative of the multimedia asset is modified to form a first resultant multimedia asset based upon which a first edit list is generated. The first edit list, in turn, is associated with the first resultant multimedia asset and linked to the original digital negative of the multimedia asset. The first multimedia asset is then modified to form a second resultant multimedia asset based upon which a second edit list is generated. The second edit list is associated with the second resultant multimedia asset and linked to the first resultant multimedia asset.
