In theory, at least, when you copy a sequence from one Team Project to another, the only items that should be duplicated are the ones that are different between the two Team Projects. That's what I see in my simple tests, too. For example: Team Project A contains a sequence and two clips, which are used in that sequence. Team Project B is initially empty When I paste or drag the sequence from A to B, the sequence and clips are duplicated in B. If I then edit the copy of the sequence in the Team Project B and paste that back into Team Project A, the sequence is duplicated in A, but the clips are not, since they were not edited. If I rename a clip or change other metadata in B, then a new copy of that clip will also be made when I paste the sequence, since the original copy of the sequence still refers to the old version of the clip, and we don't want pasting a new sequence to change the contents of an existing sequence. When footage or nested sequences are duplicated due to edits, though, there aren't really many tools to manage the duplicates yet. I think that's an area we need to look to see how we can improve things. I'll file a Feature Request to see what we can do. For now, I can think of a few workarounds for updating the Master Team Project, though none of them are ideal: 1. If there aren't too many segments, share the Master project so there's a named initial version, then delete everything but the links from the Main TP and re-import and reassemble the linked sequences. You can use the version history to get back to the original assembly as needed. Repeat as needed, sharing before each version. 2. Render the linked sequences and only import the rendered footage into the Master Project. 3. Store only bins at the top level of the Master Team Project, and quickly put any duplicate items into a new bin each time you update the master. This is because any duplicated footage or sequences are always put at the top level of the Team Project, so if you don't normally store footage or sequences at the top level, you can quickly spot the duplicates and move them to a better location. You can quickly separate the bins and links from the footage and sequences in the Team Project panel by enabling and sorting by the "Media Type" column in that panel. Unfortunately, I can't think of a more elegant solution at this point, though I'd be happy to hear if anyone has a better procedure. As I'll said before, I'll make sure we're tracking this issue if we aren't already.
