Automatic synchronization with your video

Easily synchronize your GPX overlay with your activity video automatically.

You can now generate an overlay perfectly trimmed to your activity video.

All you need is the video file from your activity (e.g., GoPro, DJI Action, iPhone). Ensure the date and time are correctly set on your camera before recording. While manual time range selection is possible, you can now simply select your video file. The overlay will automatically be trimmed to match the exact time range of your video.

Steps:

1. Verify your video file has the correct timestamp.
2. Upload your GPX file to the app.
3. In the second step, you'll see an activity chart. Above the chart (top-right), find the area to drag and drop or select your video file. Note: The video is not uploaded to our servers.
4. If the video's time range overlaps with the GPX activity, you'll receive a notification, and the matched time range will be displayed below the chart (see image below).
5. Proceed to the next step to customize your overlay.
6. Once downloaded, import both the generated overlay video and your original activity video into your preferred video editor.
7. Place the overlay clip on a track above your activity video. They should have nearly identical lengths. Check the alignment carefully; minor adjustments might be needed for perfect synchronization.
8. Enjoy your synchronized video!
