Synthetic GPX loop — descriptive transcript

Silent, 10 seconds, 1280 × 720, 24 fps. No music or narration.
A pale rectangular outline appears on a plain background. A blue marker and line
start at the lower-left corner, travel up the left side, across the top, down
the right side and back along the bottom to close the loop. The first frame is
held for approximately one second and the completed loop for two seconds.
The route-drawing interval occupies approximately seven seconds.

The heading on the embedded version identifies a synthetic GPX sample with no
basemap, rather than a recorded journey. That heading was added in FFmpeg after
GPX Animator produced the route. GPX Animator's creator credit remains visible.
The native file produced by the reproduction pack does not include that heading.

Input: synthetic-loop.gpx; nine points, one segment, invented timestamps from

near Toronto, not navigation directions or a record of usable paths.
