Field Mapping allows you to align the video view with actual pitch dimensions so you can measure static distances between players accurately.

1. Go to Main Menu → Settings to set default dimensions.
2. For the current action, open Settings in the mapping popup, enter Width × Height, and apply.
3. Units are in meters (standard football pitch width is usually 68 m, length 100–105 m).

1. On the 2D pitch diagram, click each dot/marker, then select the matching point in your video.
2. Linked points must match in color.
3. Add at least 4 pairs for basic accuracy (more pairs = better accuracy).
4. Click Accept when done.

1. Close the mapping popup by clicking the Apply button.
2. Telestration tools that use field mapping will now be active, allowing you to measure distances.

The system needs multiple reference points to correctly calculate the perspective and scale of the pitch. Fewer points reduce accuracy.

You can reopen Settings in the mapping popup and adjust the dimensions at any time before confirming. Note that the previous mapping will be reset.

Any tool that supports distance measurements or scaled tracking will use the mapped field to display real distances (in meters).

Currently, Field Mapping works only for football (soccer). More sports are under development.
