There are a number of proposals here.
The content view priority could be useful as long as it is seen as (in some sense) a sub-priority of the view priority (as one cannot thin views in an order that doesn’t respect dependency).
The usual anxieties about placing material in the movie box come up for the global information (but see below).
On content view priority: this seems useful as long as the relationship to decoding view priority is made clear (as above).
On local, global view information: this seems useful and we accept it. The global information should probably be in the multi-view group box (which may be moving from the movie level).
On the optimization of the multiview relationships: There is a gain here (space saving), but also a pain (having to follow the reference when reading). Is it worth it? Do we need to set this up more like sample groups, where there is a bag of ‘definitions’ which the views can then refer to (rather than referring to each other)? (We are not going to design this during the meeting). We insert an editor’s note pointing out the issue and asking for further comment.
