Support for GoPro Hero 12

[grewhit25]

Thank you for developing and maintaining gopro-dashboard-overlay! It's a valuable tool for cyclists like me who use GoPros to capture rides.

I use a GoPro Hero 12 action camera and a Garmin Edge 1040 cycle computer for recording my ride activity. The Hero 12 lacks built-in GPS, but fortunately, detailed ride metrics are available from the Garmin.

gopro-dashboard-overlay seems like a perfect tool to create video overlays with cycling metrics. However, the software currently doesn't support the Hero 12. Would you consider adding support for this model in a future release please? It would be greatly appreciated.

If technical differences between the Hero 12 and previous models impact support, any information available would be happy to help.

gopro-join.py was briefly explored for file concatenation, but it wasn't compatible with the Hero 12's non-continuous recording style. Additionally, the --gpx option with the Garmin Edge file and video resulted in the GPX file being ignored.

Some success was achieved by creating a video using the GPX file and the --use-gpx-only option to overlay the data, a more integrated solution within gopro-dashboard-overlay would be ideal.

I have tried a few things, output below, which maybe be useful.:

Because of battery limitations I have been stopping and starting recordings creating multiple clips for the duration of my rides.

I have a folder with a list of files, here is an example:

GX010002.MP4
GX010003.MP4
GX010004.MP4
GX010005.MP4
GX010006.MP4
GX010007.MP4
GX010008.MP4
GX010009.MP4
GX010010.MP4
GX010011.MP4
GX010012.MP4

gopro-join.py output

Notice that the files are not concatenated probably due to stream 02 not being reconignized.

I created a join script in the short term. Here is the output from the script:
I’ve only shown output from the first two files concatenation and also not the final output of the join because it takes a long time.

Hiya - thanks for your interest in the software! Yes the Hero 12 was a bit of an unexpected curveball, with no GPS.

• As long as the video times are synced to an external gpx file, the overlay using "--use-gpx-only" has been shown to be mostly ok. However, syncing the time is difficult!
• Significant work would have to be done I think to concatenate files from a hero 12 taking into consideration the lack of gps. perhaps there is an internal time signal that can be used to figure out the relative times of each clip...?
• unfortunately I don't have a hero 12, and i'm not planning on buying one - because it doesn't have gps, so is useless for me.
• given the amount of work involved, i'm not sure that i can promise special support for hero 12.
• that having been said - if you are able to share your above files with me, that would be useful to look at the data tracks, and see what there is... (please don't feel compelled! - you can email a link to them to [email protected] - maybe from wetransfer or similar)

Hi @time4tea,

I have sent some info over as requested above.
There is absolutely no pressure for you to provide any support on this issue.

Please let me know if I can be of any further assistance. I am also happy for you to just point me in the right direction.

[time4tea]

Thanks! - I've downloaded the files. I'll take a look and see if there is some way to make it work a bit better!

I use GP11. Its gps is crap - the car stopped but its gps shows that it was still moving some 100m in different directions.
Maybe this is why they dropped gsp in GP12.
You cannot pack the same 700 USD quality device into the tiny camera.

So, to have overlays later, for gps I use my own gps device that creates .gpx file with the <trkpt every second, like your Garmin does.

I later create overlay videos from that .gpx and then sync them with my GP11 videos that are 5k50fps.
I sync them according to the speed and fine adjust on sharp curves, if there are any.
Works very well.

I don't believe that you can sync .gpx data with the video based on the time stamp only.
There is no way your camera and the separate gps device, even when time synced at the start of the recording, will have exactly the same time stamp up to the very second.

So, either provide constant power to the camera for cont. recording, or sync the data when you make the video with the overlays - it's easy.

[grewhit25]

Thanks for the detailed explanation things are a bit clearer to me now.

I happen for this issue to be closed.

I am now able to create overlays using my Garmin gpx/fit file then sync to my GoPro videos.

I am now able to create overlays using my Garmin gpx/fit file then sync to my GoPro videos.

Actually, with your gps device, that has lcd screen, and probably shows the time, in particular seconds, the sync should be done very easily.
Every time you start recording in your camera, just put the device in front of the camera so that you can see the seconds changing,
then later, when you edit your videos:
look at the clip, note the exact time, open the .gpx file, remove the first lines up to the time shown in the video, and you'll have the perfect sync.

Another way I can think of is probably even more effective.
You can just start your recording in your gps device at exactly the same time when you press the camera button.

Also. Can you paste here a few first lines of the .gpx file from your Garmin device to see the structure and what data each line contains.

I have much cheaper, Arduino Uno based device that creates and updates .gpx files every second, and inside it looks like this:
