This is likely your entire issue.
All of these microcameras record media with massive data-reduction strategies, not the least of which is a non-uniform or “variable” frame rate. Most American devices state a nominal 29.97, but that is an average target for these devices, and like mp3, they drop whatever is not considered to be essential for reconstituting your motion video stream. Most consumers find it odd that an advanced application like Resolve cannot cope with a non-uniform frame rate (all the consumer *player* software is built to accommodate this technique) but keep in mind, that’s all they do.
The general approach to solve this incompatibility is to prep your field footage for editing by transcoding it into a fixed frame rate codec — ProRes, DnX, are the major families for use in post production.
Glad you enjoyed your fam-flight. I haven’t done a tow-launch for a couple of decades now. If you found that exciting, try packing all of that into about 90 seconds sometimes, which is the winch-tow approach. You feel like you’re going straight up (what is known as a tactical departure…) The trick is to keep it straight and not yaw/slide off the cable run. (costs altitude gain…)
