I. Recording, media and troubleshooting
When backing up media from the XQD cards to a
computer, hard drive or other storage it is important that
the entire contents of the card are copied retaining the
original file structure. The additional "sidecar" files on the
cards contain important metadata and other information
important for the correct decoding of the video clips. Use
a new folder to store the contents of each card backed up.
Do not attempt to merge files from multiple cards into one
folder (unless using Sony's Catalyst Browse application to
manage your content).
