# 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`.

## GPS in the video

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` |
| GoPro (data in the video) | `.mp4` `.mov` `.360` |
| Insta360 (data in the video) | `.mp4` `.mov` `.insv` |
| Novatek dashcam (Viofo, Vantrue, Transcend …) | `.mp4` `.mov` |

## Data files

If the camera writes no GPS, one of these files goes next to the video.

| DJI drone SRT caption | `.srt` (next to the video, same name) |
| FIT file (Garmin / Wahoo / Coros / Suunto) | `.fit` |
| GPX file | `.gpx` |
| NMEA 0183 log | `.nmea` `.nma` `.txt` `.log` `.gps` (next to the video, same name) |
