In the browser you can delete the master clips and then highlight the subclips you want to keep. Open media manager and use the “use existing” selection. Select delete unused media from selected clips. choose,”Clip Names”,
make sure the “Duplicate selected clips and place into a new project” checkbox is not selected. click ok. This will erase all media you do not want. Then you should be able to open the capture window, select the clips you want to recapture, reset the capture settings and you’re on your way. Thats the quick way to get your clips. A slow way is to create a new bin, drag each of your clips into the browser creating a new master clip, then open the capture window, select the clips and batch capture at your new settings.
