You are halfway there.
Indeed copy the whole card to hdd.
Then to the Media Browser and click on the STREAM directory on the hdd.
Clips will appear on the right side.
Double click on a clip and it will open in the Source Monitor, trim the ends and drag to the timeline. Clip is now imported into your project.
Another way is to double click on the Project Window and import all the clips from the STREAM directory.
Thank you very much! Greatly appreciated!
