Having examined the problem last week, and reported my findings (no dji response yet) it is fairly obvious that there is a problem with audio and video synchronisation.
The problem is with the soundtrack recording.
All recorders will drift in time, and tests show that (for example) the Zoom F8 drifts by 0.5 frames in 24-hours, The Osmo drifts 3-4 frames in six minutes.
The test is simple. Mono shotgun records into a SD MixPre-D. One output goes to a Roland R-26 recorder, and one output goes to the Osmo. Tone is applied at the start of the test to synchronise -- and then at regular intervals. Load both tracks into FXP X, align the start, and then see how the tone aligns after a couple of minutes.
You can do the test yourselves ..... and I'm sure that you probably have.
A number of people have already reported the problem, including examples on YouTube.
