How to filter out footage into one clip
There are 2 solutions:

Create a sequence with all assets that have not been used so far, but which you would like to keep. Next, use the Project Manager to export all relevant files to a new location (your archive) and have &quot;Exclude unused Clips&quot; checked. You may choose to do 2 exports: one with all the sequences for the main video except the extra sequence and another with only the extra assets sequence. When done, delete the original project folder.

Use a metadata attribute to mark which assets you do not want to keep. In the project panel, select list view and sort by that metadata column. Or you may move all the extra assets in other bins. For each bin select all the assets marked as unwanted and right click on Make Offline and select the delete option.


I think the first approach will be faster in most cases.
