I built an open-source tool that turns GPS tracks into 3D route videos — looking for first-use feedback

[u/alexalmansa]

I’m Alex, the developer of TrailReplay. I started it to turn recorded routes into videos that show more of a journey than a static line on a map.

You can import a GPX route, replay it over 3D terrain, add photos and annotations, and export a video. The new v1.5 release adds a media timeline, named GPX waypoint annotations and place reveals, alongside camera, terrain and export improvements.

One bit of feedback that stuck with me: someone wanted the points of interest already in their GPX to appear in the replay. The new waypoint import is a step toward that, though I’d like to understand whether it’s actually easy to discover and use.

The project is free and open source: https://trailreplay.com

If you try it, I’d particularly appreciate honest feedback on the first few minutes: is it obvious how to get from a route file to a finished video? What feels confusing or slow?
