I have just animated 4 different tracks from boats on the Ionian and Adriatic Seas by using time manager plugin. Everything works fine now (since I swiched over to shapefiles from GeoJSON).
The area covered by the tracks spans about 700km and I would like to render a video where time and speed labels are visible. So I would like to define a certain scale and keep one boat centered within the display during the time manager loop. Is there an easy way to do that?
