There are two sliders at the bottom, by moving them you specify the interval of the trajectory, which will remain and which will be cut. You will see a visual representation of the two colors on the trajectory. Green indicates the area that will be saved after trimming, and red indicates the area that will be trimmed.

After selecting an area, cut the part you don't want by clicking on "Trim". The trajectory will be saved to a file in the original format.
