My goodness you’re making this much harder then it needs to be, here’s how you work:
Copy files from SD card to your Raid or editing hard drive(s).
From Pr launch media Browser and nav to the folder, import just the clips you want, drag them into your project.
Now, take one clip and drop it on the “make new sequence” icon and Pr will match the sequence to your footage.
Edit.
Export.
Send invoice.
