Action cameras sometimes stamp the wrong date on a clip, so the app won't pair your GPS file. Shift every timestamp in your GPX or FIT track to match the video, then re-import.
Why timestamps drift apart
Action cameras like the Insta360 X3 write the clip's date from their own internal clock. If that clock is wrong, the video's metadata time lands days or months off from when your GPS device actually recorded — so the editing app refuses to pair them. Shift the GPS track onto the video's clock, re-import the GPX, and they snap together.
Retime shifts every timestamp in a GPX or FIT track by a constant offset so a separately-recorded GPS file lines up with footage whose camera clock is wrong. The coordinates, elevation, and spacing between points never change — only the clock moves — so your speed and distance stay correct.
In Match-video mode, drop the clip and its recording time is read automatically (even multi-gigabyte Insta360 INSV files); tell it how far into the ride filming began and download a retimed GPX, ready to pair in Insta360 Studio, GoPro Quik, or DJI.
Cameras like the Insta360 X3, GoPro, and DJI write the recording date from their own internal clock. If the battery drained or the time was never set, that clock can be days or weeks off. The footage is fine — only the metadata timestamp is wrong, and overlay apps use that timestamp to pair a separate GPS file.
No. Retime only rewrites the time on each point — coordinates, elevation, heart rate, point count, and route shape are untouched. If you started the GPS before you hit record, that early section stays in the file; it simply falls before the video and is not shown during playback.
Use Shift mode and move every timestamp by one hour, earlier or later. It is the right tool for daylight-saving gaps, a slightly wrong clock, or a whole-hour timezone difference, and it never touches your coordinates.
Yes. Retime reads the recording time directly from .insv files as well as .mp4 and .mov, even multi-gigabyte 5.7K clips — it reads only the file header and footer, so nothing huge is uploaded or loaded into memory.
