Formats

In: a video with GPS inside, or a video plus a data file. Out: MP4.

Video files

File extensions it opens: .mp4 .mov .insv .360 .mkv.

From these recordings MAPu reads the position and the other data on its own, without a separate file.

Format	Extension
BlackVue dashcam	`.mp4` `.mov`
Dashcam text track (Garmin, Thinkware)	`.mp4` `.mov`
DJI drone / camera (data written into the video)	`.mp4` `.mov`

Insta360 (data in the video)	`.mp4` `.mov` `.insv`
