Dear chuck
This is a late reply. hope can help.
My process is:
-take sequence of pictures with insta360 one R every 3 secounds;
-at same time, track my GPS location with “JAS Tracker” (app on iPhone);
-Batch export all 360 with the desktop software of insta360;
-export the GPS log to the same folder as the sequence of images
-use the desktop software “GeoSetter” to merge the location into every image;
-export to mapillary with the dedicated desktop software.
