Sequence Export is a very useful tool for exporting an event that occurs progressively through multiple cameras.

 

During video playback, you can switch cameras with object links, or manually by dragging and dropping objects from the object list into the video player, to, for example, follow a suspect who is moving between multiple cameras. The sequence export allows the video to be exported together with camera switching actions, i.e. it is possible to create an export where the exported video player will automatically switch cameras, following the actions created by the operator during the export.

 

During the sequence export, all the operator's operations, such as adding cameras to the screen, removing cameras from the screen, changing the screen layout or loading another view, will be recorded along with the time of the video playback moment when these actions took place. During video playback of this sequence export, the player will replicate the same actions, effectively changing the cameras on screen automatically.

 

To access this tool, during a media playback session, click on the Sequence Export icon in the Tool Selection Panel:

 

 

•Action History: This panel displays the user's action histories, such as adding cameras to screen, removing cameras and changing views.

•Start: Starts recording user actions for sequence export. For this button to be activated, the video session cannot be in Stop mode, it must be in Play or Pause.

•Limit Media Size: By selecting this option, the system will automatically split the exported video into the size specified in this field. During export, several folders will be created whose files will have the maximum size specified. This option is useful if you want to save the video on removable media that is limited in size.

 

To create a sequence export, simply position the video at the beginning of the period you want to export and click on the Start button. From this point on, all the actions (changing cameras and views) will be recorded, so now you can click Play and change cameras as necessary. At the end of the session just click Stop and the Export button will be enabled, and the export of the sequence can be completed.

 

With this, you can create an exported sequence, where the Video Player will automatically switch between the cameras, following the exact moment when the operator switched between the cameras during the export session. Here's an example of how to export a sequence.

 

In this example we will create an export to follow a suspicious person leaving a building, passing through multiple cameras. First, we position the video at the start of the export and click Start. From then on, all the user's actions will be recorded. Initial actions will be added automatically, containing the View layout and the initial cameras on screen:

 

 

Now we click Play and to follow the suspect between the cameras, we use links to pre-registered objects, in this case of the image above, we will click on the arrow pointing to the left, which is linked with a camera positioned in the exit corridor:

 

 

By clicking on the left arrow, the linked camera will be loaded, and we can see the suspect crossing the corridor to exit the building. Then we continue with the video playback and now click on the up arrow, which represents a connected camera that is outside the building:

 

 

The corresponding camera will load and all these actions have been saved in the export script. At the end of the investigation, we will click on the Stop button, as shown in the previous figure, and then the Export button will be activated and we can start the export:

 

 

When you click the Export button, the system will use Native Format Export, already explained in the Native Format Export topic.

 

After configuring the export in native format, the system will start the export:

 

 

Once the export is complete, you can play the exported sequence using the steps described in the topic Playing exported videos in Native format, the only difference being, when you open the main window of the exported Media Player, you will select the Start Sequence button instead of Start Normal:

 

 

•Start Sequence: Starts video playback using the sequence script to switch between cameras automatically, following the script created by the operator during export.

•Start Normal: Starts playback with all the cameras used for playback in an Automatic view.
