multicam stopped working. fixed by resetting preferences but should I convert to productions?

1) Figure out your organization. It is suggested that you have separate folders within the Production for your major items, subfolders as needed, and projects within subfolders.

Such as a Media Projects folder, or Assets folder; a Sequences folder, a Finals folder, whatever.

And perhaps a parallel folder structure but outside the Production folder for actual assets such as media, that are then ingested via media/asset Projects in the appropriate subfolder. Even unto days or whatever.

2) Create that overall structure as puzzled out above.

3) You might do something then like 'add' the current project to the Production, using it either for the Assets/Media storage (as it's got all references/Source data) or Sequences. I'd suggest using this as your Assets folder, then dragging Sequences to the Sequences project you've created.

4) Test it out ... and you've tested this with duplicates of your media and sequences/projects, right?  lol

5) If all else fails, read through their actually worthwhile files:
