Abstract
A novel NLE system and method of constructing edit sequences includes reference clips which can be employed in the sequences. The reference clips include a reference to metadata defining a child sequence. The reference clip is loaded into a parent sequence in the NLE system, rather than the netadata for the child sequence and, as the reference clip and its reference typically have a much smaller memory footprint than the metadata for the child sequence, the memory requirements for the NLE system to load the parent sequence are reduced, as is the time required to accomplish the load. In addition, the metadata defining the child sequences can be persisted separately from the parent sequences, and used in a any parent sequence by employing a reference clip to the persisted child sequence. This also allows multiple instances of reference clips to a child sequence to be employed, in a single parent sequence or in multiple parent sequences and by multiple users. New versions of a child sequence can be automatically employed in any subsequent playback of a parent sequence which contains a reference clip referring to the child sequence. Further, access control, security, and version contro…
