Generate video metadata

Available with Image Analyst license.

You can generate metadata for videos from stationary sensors—such as security cameras—that do not have the required metadata for Motion Imagery tools in ArcGIS Pro. Previously, only video data collected by specific sensors could use the complete set of tools in Motion Imagery due to availability to complete metadata. With the Generate Metadata tool, you can input the required sensor information and create a .ts file that will be accepted by ArcGIS Pro and ArcGIS Video Server.

Set up ArcGIS Pro to generate metadata

To generate video metadata, complete the following steps:

  1. Open a new or existing ArcGIS Pro project.
  2. Load your video that does not have any metadata, or the side car metadata file.
  3. Click the Video Player window tab.
  4. Click the Metadata contextual tab.
  5. Select Static Sensor to generate video metadata for a static sensor.

    The tool window appears with your video preloaded on the Input Window dialog box. If you have multiple videos in your project, you can choose a different video in the drop-down selector.

Sensor Information

Using the Sensor Information set of prompts, generate the required video metadata needed for Motion Imagery tools. The more information you can provide, the better your resulting video footprint and functionality.

Generate video metadata sensor information.

You have two options to set the Sensor Location. You can either manually enter or paste the sensor coordinate, or use the Point Select Tool.

Note:

You must have the Map window selected for the coordinate selector tool to be enabled.

The Height parameter allows you to offset a sensor vertically. Once the height has been input, you must specify the units and whether the height is above terrain, an ellipsoid, or mean sea level.

The following parameters will help provide the best possible footprint for the video, allowing Motion Imagery tools to work with the video metadata:

  • Tilt—The up and down movement of a sensor, where the vertical angle capture views above or below the horizon. Positive values are pointed upward, negative values are pointed downward, and 0 degrees is level with the horizon.
  • Relative Azimuth—The left and right movement of a sensor. A zero value is pointed due north and 180 degrees is due south.
  • Horizontal Field of View—The angular width of a sensor's view horizontally. Smaller values represent a narrow view and larger values have a wide-angle view.
  • Vertical Field of View—The angular height of a sensor's view vertically. Smaller values represent a narrow vertical view, and larger values show a larger span above and below the frame center.
  • Far Distance—The farthest distance at which a sensor is able to discern the desired objects in the video. Once this optional box is checked, you can set the distance and unit of measure.

Dynamic Preview—Allows you to see the footprint on the map before running the tool, if parameter values are entered.

Time values

Setting an accurate Start Time is critical for the video to be geospatially accurate and temporally accurate. If the Start Time is not accurate, other tools such as Video Search will not work correctly and generate incorrect results. The tool uses the time input and video length to extrapolate the time values for each frame.

Since the time is converted to UTC, the Start Time field must be filled in accurately. Generate Metadata tool Time and Output Files options

Output Files

You can name and set the file location for the Output Video File and Output Metadata File. The Output Video File is required, and will be a .ts video file. The Output Metadata File is not required, and will export a .csv metadata file that can be reviewed and saved.

Add to Map

The last option on the Generate Metadata tool is Add to Map. This option will add the exported .ts video file to the project once the tool has completed.
