When you're satisfied with the rough assembly you created with Quickture, make a copy of your sequence before you start editing manually.
Quickture is designed to get you to a rough assembly or a rough cut, then allow you to continue your edit on your own. Once you begin making manual changes to the edit, you can't use Quickture to make refinements anymore. But if you duplicate your sequence before you start making manual edits, you can always go back to it to continue making Quickture refinements.
Remember Quickture can keep helping later in your post process! You can go back to your Raw Sequence and generate clip pulls to incorporate into your ongoing cut.
