[Bob Flood] “so, how can i get this nest, the good one, into my browser to rename it”
I’m not sure, but I bet you could drag it straight from the timeline to the browser. If not, drag it from the timeline to the viewer, then drag from the viewer to the browser. I haven’t tried either, but I bet it’ll work. Although, after you drag it to the browser and rename it, I’m not sure if that will create a “copy” or an “instance” of the original. (Maybe someone else will comment.) So, after dragging it to the browser, if you find that it is a copy and not an instance of the original, simply drag it from the browser to the viewer or timeline and replace the original nest in the timeline. I know that will create an instance and you’ll be good to go.
[Bob Flood] “How can there be 2 versions of the same sequence? one in the browser thats different from the one in the timeline?”
Like most everything in FCP, there are several ways of creating and/or dealing with nested sequences. Some of the ways actually create or deal with a “copy” rather than an “instance” of the original. Rather than getting into all the details, I’ll just tell you what works very well for me.
When I want to nest a sequence into another sequence, I always drag the sequence from the browser to either the viewer or directly to the timeline. By doing so, you can treat it as if it were just a clip and you will also always be working on the right sequence. Whether opening the original sequence from the browser or by double clicking on it in the other sequence, you’ll always be editing on the original and it will always update at both places.
If, on the other hand, you desire to use a copy of a sequence as a nest inside another, I would duplicate it first, then rename the duplicate, then drag the duplicate to the viewer or timeline.
If on the other hand, you desire to use only part of the sequence that you’re already working on, and wish to just nest a complex part, I would copy all tracks for the duration of the complex part, then create a new sequence and paste that into it, (be sure to drag out some heads and tails if you wish to have a transition at the start or end), then save that and drag it from the browser to the viewer or timeline.
You can see my pattern. I always drag from the browser. There are other perfectly good ways, but that’s the one that works for me.
Hope this helps,
