DIGITAL ZOOM
Digital zoom in video playback operates differently than it does in Live View as described at the
beginning of this chapter. Both are digital zooms where the image is electronically enlarged - usually
in exchange for a decrease in image clarity. You can digitally enlarge an area of a video by clicking and
dragging with the cursor on the area of interest. This action will draw a green rectangle on the screen.
When you release the mouse button, the cursor will change to a magnifying glass.
Click within the border to zoom into the area. If you need to re-draw the box, merely click outside the
area to dismiss the box and then re-select the area.

In the case of a multi-screen viewing mode, the
zoomed-in view will fill only that portion of the
screen occupied by that channel. You can switch
to single-screen mode by double-clicking on the
screen as described earlier. You can also go to
full-screen mode and back to multi-screen mode
as well. Right-clicking with the mouse will return
you to the full channel view.
VIDEO CLIP
This allows you to save only a portion of a video clip. For example; if you have a camera set to record all
the time and it captures some action in a five-minute segment, you can clip only that portion and back it
up. In addition to making an incident readily available, saving only the portion of interest will reduce the
amount of disk space needed to back it up.
STEP 1. Select a file to view in the normal manner.
STEP 2. Find the section of interest and press the Clip button (a)
STEP 3. Drag the playback bar to the end of the section, or allow the video playback to progress to
the desired endpoint and press the Clip button again.
STEP 4. Press the Backup button (b) to save the file to a USB drive connected to the USB back-up
port on the front of the NVR. It is not possible to save the edited clip to the NVR’s hard drive.

SAVING A FILE
This process lets you back up the files you’ve selected. If you want to back up a lot of files, please see
the next section. Once you have backed up these files to an external USB device they can be played
back on a computer.
You must have a USB device connected to the USB port on the front of the NVR before proceeding.

STEP 1. In your file list to the right of the
playback screen, check the box next to the
file(s) you wish to save.
STEP 2. Click on the Backup button (item
b in Picture 3-13) and the Backup
window will open.
STEP 3. Your device will be listed at the top of
the window showing how much space is
available. Below it, the list of file(s) you wish
to back up will be displayed along with
type, start and end times and size. At the
bottom of the window, the space required
to save the file(s) will be displayed. You
may uncheck any files you do not wish to
back up at this time. The Remove button
will remove all the files from your list.
STEP 4. Choose the video format you want
to save your file(s) in - .ASF or .DAT. Files
saved as .ASF can be played in most video
playback programs.
STEP 5. Press Start to back up your selected
files.
NOTE! If the video files are in .DAT format, they will not play outside the NVR
without being converted to .avi format using the included General Player
software included on the Manuals and Software disc that came with this NVR
or available for free download at Q-See.com by searching for your model
number and looking under Software. This software can also convert the .DAT
files to .AVI
Right-clicking the mouse will exit this window without saving the files.
Right-clicking with the mouse will exit the playback window.
