Sync
The data is off by an hour or more
Some action cams save local time as if it were UTC. On the Sync screen, use −1 h and +1 h, then fine-tune with the slider.
“No GPX data at this time”
The video isn't within the track: check that you picked the GPX from the same outing, or fix the time zone as above.
The value is right but a few seconds late
Find a recognizable moment (a start, a turn) and use −1 s, −0.1, +0.1, +1 s until the numbers match.
Import
The video takes a long time to load
If it's on iCloud or a server, the app downloads it before copying it: you'll see the progress and can cancel at any time.
“The track has no times”
Some GPX files exported from route planners contain only the route, without times. Export the recorded activity, not the planned route.
Export
Which quality to choose
High (HEVC) makes smaller files at the same quality. Compatible (H.264) plays everywhere, including computers and older devices.
The export stops
Keep the app open while exporting and make sure you have free space: a 4K video takes about 200 MB per minute.
FAQ
Where do I get a GPX file?
Most tracking apps export one: Strava, Garmin Connect, Slopes, Komoot, Suunto, Coros and many more. For Apple Watch workouts, an app like HealthFit or RunGap can export them.
Does it work with GoPro, DJI and Insta360?
Yes. TrackFrame reads the recording time stored in the video. Many action cams save it in the wrong time zone: the app notices and fixes it, and you can always fine-tune by hand.
Are my videos uploaded anywhere?
No. Everything happens on your iPhone: no account, no servers, no tracking.
Which data can I show?
Speed, pace, distance, time, clock, altitude, grade, ascent, descent and elevation profile.
Can I export vertical video for Instagram or TikTok?
Yes: with the Format tool, choose 9:16, 1:1, 4:5 or 16:9 and drag the crop wherever you want.
