Uploaded video gets cut short and wrong GPS position on images

[Johand]

Hey!

Been playing around with exiftool, mapillary_tools (v0.14.0b1 and v0.13.3) and the Mapillary uploader (v4.7.2), but have had no luck with getting my video working

Shot on a Insta360 x4, timelapse with 2 sec between shots. Used my phone to start/end recording and made sure to always be unlocked so it could use GPS from it.

When I add the video (folder with just the .insv and .mp4) to Mapillary uploader, it looks great. The entire GPS path is mapped, so I upload.

My issue is that once the upload completes the “Processing 1 capture from Aug 3” at https://www.mapillary.com/, the trip ends up way to short at only 263 images and images are at the completely wrong location. (Uploaded sequence on 3 Aug 2025 12:38 Mapillary, I’ll delete it soon since it is completely wrong)

I got the raw files if someone from the mapillary team wants it

Possible useful info:

For fun I did export the .gpx file from Insta360 studio, and it is way to short. So seems that isn’t getting the full trip. Matches the length that is incorrectly assumed by mapillary.com processing.

So I did a desperate attempt to create a export myself: exiftool -m -ee -api largefilesupport -progress -p gpx.fmt KrokeroyVest/VID_20250803_124029_00_005.insv > ./tool_export.gpx and that did create a full GPS route

Very strange, would you mind sharing the original files in a Google Drive or other method for us to take a look? cc: @tao

Same issue here, it looked great on Desktop Uploader map but once uploaded, the sequence appeared squeezed on 95% of the actual GPX track. Started at the right spot but ended a couple hundred meters before the end, as if camera time was slower than real time. Will upload and send you.
