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 - shows object distribution in time for a whole video or for the specific movement. The higher the intensity of the traffic, the stronger the colour. This metric can be very useful e.g. for various movements or different object classes comparison within one movement.

Occurrence - works for both events and movements. For events, this metric indicates the start and end time, while for movements, it marks the moment of trajectory crossing the line of the movement. Occurrences that are very close to each other are aggregated. To see the details, click on the event.

NOTE: If your video is stored on the platform, you can play back the event directly on the "Scene" page.

Peak Hour - indicates the peak hour for a specific movement on the timeline and could be used, for example, for to compare the two mains movements in the scene. To view details, click on the peak bar in the timeline metric. You can use the scale button in the top-right corner to zoom in on this peak interval.

Video playback

When analysing the traffic situation in Video Insights, it is sometimes useful to check certain traffic events visually in the original footage. If your original video files are stored inGoodVision Vault, you can play those anytime on the 'Describe 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 function is to limit the displayed timeline data for selected intervals, which can be very useful for long video analysis.

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).
