What is this “other bins” folder you mentioned?
Unless you are on mc7 and it’s completely different, you can move whatever bins you want out of the project and into any project you like. They are accessible at the finder level. Where as in FCP you can’t open the project at the finder level and see what’s inside.
You can have your own Avid project and do whatever you like, the bins are not project specific. Unless you are sharing a project over some sort of media share with someone else, then you see whatever bins they make and they see whatever bins you make and if you delete a bin they won’t see it anymore either. Is that what you’re talking about?
OH!!! I know what you mean about “other bins”. Those are bins you open from outside of the project. You can do that but I don’t use that for anything important, just if I need to peek or if I opened a bin by accident from somewhere else. I would advise against using that as something regular, just stick to working with bins inside your project, then you’ll always know where they are.
Sounds like you just need to get used to sharing a project. It’s great! You’ll love it. But yes, all the bins need to stay in there if anyone accessing the project needs them. I just make a good folder structure so the bins are filed away by category and you can easily find and access them when you need to. And some of the redundancy you mentioned in your first post may be a good thing. There may be a reason for it.
Also, beware of the lock on the bins if you are indeed sharing a project. If the editor is cutting in a reel that’s in a bin you open you should have a red lock light on it. If you do you can’t make changes, well you can make them but it won’t save. If it asks you if you want to save it as another bin don’t do it. Just say no, then option drag the clip you made changes to into a new bin to save your changes. I might be giving you too much other info, if so ignore this for now. When you need it you’ll think oh, that’s what she was talking about. 😉
