Does hypersmooth kill GPS?

[ New ]

Many people complain about GPS error.
I tested a lot myself and noticed the following.
If hypersmooth is off, GPS data will be retained.
Watch the video below:

If the hypersmooth is turned on, it will, in a good case, record the GPS data for a while and then the data will disappear.
Watch the video below:
https://youtu.be/OuvCTY0zRKo
Everything is fine on the video until 1:11, then no more GPS data.

Based on these, it seems to me that the hypersmooth takes up a lot of resources and does not remain a resource for GPS management.
This is definitely a software problem.

Hero 94K 30FPSBitrate Normalhypersmooth OFFGPS Data okay
Hero 94K 30FPSBitrate Normalhypersmooth ONGPS Data lost after 1:11

could be an excellent observation!!!!!

 

I have a hard time myself in adding the GPS data.

on my MTB with hypersmooth on, I was never able.

 

when I use it as dashboad camera in my car, I do not use stabilisation.

still this is one of the only case in the car when I was able to add GPS stickers.

https://exiftool.org.
But I'm afraid it's a bit more than just install the .exe.
You'll need to read further, e.g. https://exiftool.org/forum/index.php?topic=11189.0
Can you upload your original file somewhere and share the link here?

exiftool rocks!!!!!   thank you!!!!!

 

is strange.....GPS data are plenty - could be the GoPro mobile app....

 

I have MTB videos for which I can add GPS data, hypersmooth was on.

- I have a 5min video

- depending on where I start the clip (1min) I might be able or not to add GPS  stickers

 

 

11min 6sec duration

641 GPS timestamps (almost each second)

total 12089 GPS Lat/Long/Altitude/Speed/Speed3D readings - so 19 reads/sec

in windows you have only to extract the exe.

rename it at exiftool.exe (from exiftool(-k).exe)

 

and use it like:

 

c:\tmp\exiftool>exiftool -ee GX010111.MP4 > all_exif.txt

 

in the all_exif.txt is everything.

 

if you follow their forum, you will see example for extracting only GPS data in CSV files, etc......
