VIRB 360 video-fit synchronization

Hi,

Does anyone know how virb edit automatically recognises and matches the camera .fit telemetry with the video for the VIRB 360?

I am transcoding my 5.7K videos to h265, because I have a hardware encoder/decoder for that(intel quicksync). The transcoded videos import and play fine, however I cannot get Virb edit to automatically match the .fit telemetry to the video, and I would rather avoid having to do it manually.

I have tried copying the metadata over with both exiftool and ffmpeg, in particular all relevant dates and times, but still nothing. I assumed they would embed gps timestamps in the video/frames, but I cannot seem to be able to find them.

Has anyone had some success with something similar?
