How to create metrics on the timeline and review them with video playback

Timeline metrics

For advanced event analysis, you can now add various metrics to the video timeline. These metrics can be created and managed in the right panel, similar to movements and events. When creating a timeline metric, you can specify a custom name and choose its color for better organization.

Once a metric is calculated, you can activate and display it in the timeline section. The number of metrics displayed on the timeline is limited to six, including default one. You can also drag and drop them to rearrange their order.

Metrics types

Distribution - Displays object distribution over time for an entire video or a specific movement. The higher the traffic intensity, the stronger the color. This metric is useful for comparing various movements or different object classes within a single movement.

Occurrence - works for both events and movements. Occurrences that are very close to each other are aggregated. To see the details, click on the event.

  • For events, this metric indicates the start and end time, see example below.

  • For movements, it marks the moment of trajectory crossing the line.

NOTE: Store your video is Vault after the processing to play an event on the timeline. The playback is not available if the video is deleted.

Peak Hour - Highlights the peak hour for a specific movement on the timeline. This metric can be used to compare the two main movements in a scene. To view details, click on the peak bar in the timeline metric.

Video playback

When analysing the traffic situation in Video Insights, it is often useful to check certain traffic events visually in the original footage. If your original video files are stored in GoodVision Vault, you can play those anytime on the 'Scene' page via the video playback feature.

This feature was designed to bring value, especially to traffic modellers who need to quickly jump to a video during the analysis to check the real situation (without the need to open an additional video player). Video playback is currently supported only for videos in mp4 format. Other video formats will be supported soon.

For highly detailed analysis, you can also use the time filter tools in the upper right corner of the timeline.

  • The ‘Calendar’ tool is used for scenes with multiple days of processed data to limit the timeline display to a single day.

  • The ‘Boundaries’ tool is used to limit the displayed trajectories data for a selected 1h range (or shorter) for detailed analysis. When the tool is enabled, two more actions are available - interval reset and zoom (see the picture above).
