Hi

Best practice means you should work from the SD card directly the files need copying to the PC..

You can copy the video files from the SD card to a folder on your computer using Windows Explorer

OR

Using Movie Edit Pro:

Select File, Record audio/images/video

Select the option indicated in the image below

Select the options in the order shown in the next dialog below

1 and 2  - select the source folder on the SD card

3 - select the destination folder on your computer where you want to save the images.

4 - select the videos to be copied - see note below.

5 - Copies the video from the folder set in 1 and2 to the folder set in 3

The videos should be added to the timeline automatically.

Note:  Memory cards and USB sticks are prone to failure - without copying all the video files to the computer and having backups you risk losing them by formatting or failure of the SD card

I would suggest you read the installed PDF manual available under Help.
