Invalid GPS coordinates in GPX export from GoPro 6
on 10-07-2018 04:40 AM
I am trying to export a GPX track from an MP4 video filmed on GoPro 6.
Somehow I'm getting invalid coordinates. I see several problems which appear on the exported GPX track - but which I don't see on the GPS gauge in Quik.
First problem is that I'm getting completely off-the track coordinates. Here's a example:
The video is filmed in Germany (around 8.663, 50.232). A few first points on the exported GPX track lie north of Canada (-128.4998971, 80.8641778). Also the elevation for these points is exported as 20841.167 (in reality should be around 202).
Quik seem to show this track correctly:
The complete video is ca. 3.4GB so I can't reasonably share it. I also don't know how can I cut it while keeping all the streams including GoPro MET.
The .bin file I've exported from the video:
This is how I've exported it:
ffmpeg -y -i GX030039.MP4 -codec copy -map 0:3:handler_name:" GoPro MET" -f rawvideo GX030039.bin
The exported GPX track:
gopro2gpx -i GX030039.bin -o GX030039.gpx
I've tried gopro2gpx from:
With the same result.
Invalid points look like:
<trkpt lat="80.8641778" lon="-128.4998971"> <ele>20841.167</ele> <time>2018-09-29T10:20:53Z</time> </trkpt> <trkpt lat="80.8641778" lon="-128.4998971"> <ele>20841.167</ele> <time>2018-09-29T10:20:54Z</time> </trkpt>
First valid point:
<trkpt lat="50.2319754" lon="8.6630605"> <ele>202.121</ele> <time>2018-09-29T10:23:51Z</time> </trkpt>
Did anyone experienced similar problems?
Are there any official tools for GPS data export from GoPro?
