To play recorded video footage, double-click a camera from the Video Search Results pane. A Playback window will open with the Video Footage Queued up. Multiple Playback and Live Windows can be open at the same time.
Information about the camera feed is displayed below the Playback window. This information includes the playback status, the date and time of the footage, the frame rate (if currently playing), the resolution, the recording CODEC of the footage, the current frame number and the total number of frames.
A visible bar that displays the current cache level can be found just below the Playback window. A green bar indicates the cache level is full and if the bar is almost all red it indicates the cache is low.

3xLOGIC’s VIGIL Client - Users Guide Page 63 Markers Tab
During playback, if only a sub-range of the loaded footage is of interest it can quickly be selected by using Markers. To use Markers, select the Markers tab from the Advanced Features section.
Start / End Range
Position the footage navigation slider at the beginning of the sub-range and click the Start Range button. You will notice a small marker appear below the starting point. Next, navigate to the end of the sub-range and click the End Range button.
Clear Removes the sub-range markers. If the sub-range is cleared when the View button is latched on, the playback will return from the sub-range to the fully loaded footage.
View Loads the sub-range for playback. The playback information will indicate that a sub-range is currently displayed. All of the playback controls will operate on only the sub-range of footage.
Note: If a sub-range has been defined, only the sub-range will be saved when video is exported.
Buffering Tab
Depending on your Network/Internet bandwidth, it might be useful to configure the playback caching. Using Autosense for the most part will be the most efficient. Only advanced users should attempt to adjust the buffering settings.
Auto Sense This is the default value and the recommended setting. It will enable the buffering to become dynamic and change as required.
Buffering Connections
Changes how many buffering connections will be used. Each buffering connection opens a TCP connection to the DVR, increasing possible bandwidth; but may be limited on CPU usage, as well as the maximum throughput to the DVR.
Look-ahead x Frames
This is the number of frames that VIGIL Client will buffer during playback. Settings from 30 to 1800 frames are available. A higher number of Look-Ahead frames is recommended for DVRs recording at higher frame rates.
Cache All Cache the entire video before beginning Playback.
3xLOGIC’s VIGIL Client - Users Guide Page 64 Audio Tab
If audio recording is enabled and configured in the DVR settings, the Audio tab will become available in the Advanced Features section of the Search window. Selecting an audio channel from this tab allows you to playback recorded audio along with video footage.
To choose which audio channel to playback, select the channel from the drop-down menu in the Audio tab.
All Audio When selected, all audio from the specified channel is played back even when there is no corresponding video footage for the playback time.
Video Only Audio When selected, audio from the specified channel is played back only when there is corresponding video footage for the playback time.
Audio Level Meter This Audio Level Meter indicates the signal strength of the currently playing audio.
Visual Search Tab
Visual search is a graphical representation of the search results. The visual footage shows the period of time searched with footage recorded displayed as blocks of color representing the recording mode: Green for Constant, Blue for Motion or Red for Alarm.
When the mouse is moved within the display, a line is drawn indicating the point in time under the cursor, which is displayed in text between the footage start and end times. Clicking within the chart will begin playback of the camera at that time.
Controlling Playback Video with Digital PTZ:
Cameras can be controlled during playback using the digital PTZ camera control just like in a Live Viewer Window. Because digital PTZ controls the camera through the software, it can be used for both live and playback video. The digital PTZ controls will work for every camera that is loaded for playback regardless of the camera control type specified in the settings.

Playback Right-click Menu:
Remove Closes the Playback Window.
Copy Copies a still shot of the current image to the Windows clipboard. If the image is zoomed in, a Copy Zoomed option will be available as well.
For cameras using the Panorama PTZ camera control type, the video can be manipulated in the playback window using the following right-click menu options:
Source Video Only (Rotate Disabled)
This option is enabled by default. This feature allows users to zoom in and move cameras during playback. Click on an area of interest and then use the mouse scroll to zoom in. Click-and-drag to move the image after it is zoomed in.
Source Video Only (Rotate enabled)
This feature allows users to zoom in and rotate cameras during playback. Click on an area of interest and then use the mouse scroll to zoom in. Or, click-and-drag to rotate the image.
360 View and Source Video
This feature splits the playback image into 4 quadrants. The first quadrant shows the full image, and the second, third and fourth quadrants show different zoomed sections of the image. To load an area of interest in one of the zoom quadrants, click on a zoom quadrant and then click on the first quadrant to load that section. The zoomed sections can be clicked on directly and then rotated.

11 Exporting
Video footage can be saved either as a single frame still shot or as a video file. Audio and POS/ATM data can be saved either embedded within video footage or in a separate document. This process is referred to as
“exporting”.
Note: To export footage there must be at least one export destination configured.
Note: If Export Auditing is enabled on the DVR, required information must be entered before selecting the destination folder for both images and video exports.
