Overview

After reviewing a video, you can make a local copy of this video, to be used eventually to create evidence files. Evidence Manager supports two ways to do this:

  • Save a video that is currently playing
    When you choose to save a video, Evidence Manager opens the Save Video window in order to complete the save operation.
  • Export a video from a device
    To use this option, you must have a video from a device currently playing. When you choose to export a video, Evidence Manager opens the Save Video window for you to complete the export operation. However, because the export option is meant for saving an excerpt of the video, the time is preset to 15 minutes. You can however, change the time if you feel the need to.

NOTE: Difference Between Save and Export

The action of saving and exporting are similar except for one difference — in the case of exporting, the duration of video is pre-selected to 15 minutes. Otherwise, both saving and exporting are executed from the same window.

If you attempt to save or export a live video, keep in mind that only the part of the video that is already recorded can be saved. Make sure that you select the date and time accordingly.

NOTE: Video Extensions

The .avr and .avs extensions are available for videos that are recorded on devices other than the Mobileview devices. These videos can only be saved with the following extensions: avr, .avs, .avi, .mp4, or .exe. On the other hand, the .video extension is available for videos from MobileView devices only. Videos from the MobileView devices can be saved with the following extensions: .video, .avi, .mp4, and .exe.

NOTE: Stream Type of Videos

Evidence Manager automatically selects a stream type depending on the disk space.

  • If there is sufficient disk space, Evidence Manager selects the Main stream, in order to download a higher resolution, larger file.
  • If there is a space restriction, Evidence Manager selects the Sub stream, in order to download a lower resolution, smaller file.

Procedure

To save or export a video:

  1. Log in to Evidence Manager.
  2. Do either of the following:
    1. Load a video. For instructions, see Opening Videos, and click the Save Video Clip icon.
    2. Expand Devices under Device Manager, right-click a connected device, and click Export Video.
    3. Expand Docking Stations under Device Manager, right-click a docking station, and click Export Video.
    4. Right-click the video of your choice from the list of videos found while Searching for a Video Using Events and Alarms, and click Export Video.
  3. On the Save Video window, do the following:
  • Item 1
    1. Name: Enter a name for the video. For a system-generated file name, click Auto generate filename. Evidence Manager generates a file name in the format that you set while Setting the Filename Format.
    2. Type: Select the file type: .avr, .avs, .video, .avi, .mp4, and .exe. If you select .avs or .video, an Evidence Player instance is created along with the video. If you select .exe, Evidence Player is embedded inside the video. .avr and .avs extensions are default extensions for Seon videos, while the .video extension is the default extension for MobileView videos.
    3. Resolution: If you are playing a .avr or .avs video, and you set the type to .mp4 or .avi, choose either Native, Medium (720×480), or High (1280X720). This creates one file per channel. For .avr or .avs videos having fewer channels, two additional options are available: Medium (720×480) – Composite or High (1280X720) – Composite. This creates a single file showing all channels in a grid. If you are playing a video recorded by a MobileView DVR, and you set the type to .mp4 or .avi, this value is auto-populated to Native.

NOTE: Resolution Selection

For proprietary file extensions (.video, .avr, and .avs), if you set Type to the same format as that of the source file, the Resolution list automatically changes to Native, implying that the exported file will inherit the resolution of the source file. If you set Type to .avi, .mp4, or .exe, the Resolution list automatically changes to Default, implying that the exported file will have a default resolution.

  1. Frame Rate: Select Original if you want the exported video to inherit the frame rate of the source file. Otherwise, specify another value, such as 15 fps or 30 fps.
  2. Folder: Select the folder where you want to save the video file.
  3. Start Time: Set the start date and time of the video.
  4. End Time: Set the end date and time of the video.
  5. Stream: Select a stream type depending on the disk space. If there is sufficient disk space, select Primary to download a higher resolution, larger file. If there is a space restriction, select Alternate to download a lower resolution, small-sized file. For .avr or .avs videos, Stream cannot be changed, and is set to Primary. This is because for exporting these videos, only the Primary stream is supported.
  6. Include Audio: Select this check box if you want to include audio along with the video.
  7. Include Metadata Overlay: Select this check box to include metadata overlay in the exported file. If you select this check box, the metadata of the video will appear as an overlay in the exported video.
  8. Select All Cameras: Select this check box to select all cameras for video export.
  9. Cameras: Select the cameras from which you want to save videos.
  1. Click Start to begin.

The Free Drive Size bar indicates the progress of the operation. If the download is interrupted, save the file again.
