Hero 8 / GoPro Max Telemetry
[ Edited ]

Hi,

 

Just creating this thread to gather information on the metadata available in the new Hero 8 and Max cameras.

All info is welcome, especially sample files.

 

Edit. The 8 has got some new sensors (or rather new data streams)!

Camera orientation, image orientation, gravity vector, wind processing, microhpone is wet and audio levels

I just updated the online telemetry extractor ( https://goprotelemetryextractor.com/free) to support GoPro Max's .360 files. They contain a new stream called Disparity Matrix

Hi,

 

could anybody try this (

) with the hero 8 and rotate the cam while filming and see if horizon stays levelled, even if upside down. With Max I saw it works, but with hero 8...?

Thanks

Re: Hero 8 / GoPro Max Telemetry

Can the telemetry overlay be done on the hero 8 black?

 

I've recently bought one, and can't seem to get it working. the Gopro GPS is solid. The quik desktop just says: "Guages are only available for videos captured with the Karma drone, or HERO5 and newer cameras with GPS turned on."

 

The quik for mobile says there's not GPS DATA try uploading direct from your GoPro.

 

Any help in this would be greatly apprecaited. 

 

Running Mac version of Quik and downloaded latest software for both.

 

Thanks

Re: Hero 8 / GoPro Max Telemetry

@silkem552 I am interested in knowing that too. Unfortunately I don't have a hero8 to test it with. If anyone here does, I suspect the results will be better when recording in 4:3 formats (instead of 16:9)

 

@dan9780 It appears to be a problem with the Quik software. A fix is expected.

 

Other than that, telemetry wise, a nice addition to the new cameras is that they store a microsecond time stamp for many of the streams, which makes syncing them with the video frames easier and more accurate for other software.

Re: Hero 8 / GoPro Max Telemetry

I have just tried this for you.

 

It does work, but massively crops the video. Like I'm talking it tookt the centre quarter of the image and stabilised it. But i did rotate it a full 90 degrees. 

 

the less initial rotation the less it would be required to crop.

 

Hope that helps

Thanks for that, hope it comes out quick!

Betreff: Hero 8 / GoPro Max Telemetry

Does it crop as much as "reelsteadygo"? I guess if you only rotated 90° and it leaves only the center quarter, what happens if you fully rotate it 360°? Any sample footage available?

Re: Hero 8 / GoPro Max Telemetry

Hi

 

So unexploitable...

 

Just pass under a tree and path gets anarchy, speed peak climbs to 24000km/h, same with altitude... so pass between 2 buildings after 3 hours on the road and all the path go into the trash.

 

Accelerometer and gyroscope return "unkown error".

 

Try to show data doesn't work with Firefox, it crashes tab.

Re: Hero 8 / GoPro Max Telemetry
Hi @sylkgx , I will have a look at those two last errors. Could you send me a sample file to app@prototyping.barcelona to test it? A .LRV file is fine too if you keep them.

Regarding location going crazy, does playing with precision and fix not help filter out those data?

Re: Hero 8 / GoPro Max Telemetry

Tall buildings can cause you to lose GPS lock, however Gyro and Accelerometer data shouldn't be affected.

 

Perhaps it's a hardware issue. You should try to get a replacement.

 

@kajuna might be able to help you get proof that the unit is faulty

Re: Hero 8 / GoPro Max Telemetry

@kajuna 

Playing with precision refine path where signal is ok but doesn't fix speed and altitude where the signal was "lost" or "not sufficient".

Even where signal is ok, Altitude does not faithful; Start point (higher) and arrival (lower) looks good but between it is just a yoyo, where each meter of the road should be lower than previous, but on the graph no. See pic.

 

No LRV, so i'll redo a run and send you it ASAP.


At least one good point: Firefox issue seems to be fixed.


Are you sure the Hero8 still have Accelero and Gyro onboard??

Re: Hero 8 / GoPro Max Telemetry
I see some interesting things to note here.

GPS based altitude is not very reliable. That's why drones use barometers instead. Some drift or error is expected.

The Hero 8 does have accel and gyro. From the symptoms you describe, I suspect you are facing performance issues that end in a soft crash either in your browser or in my server.

The server limitations can be overcome with the offline version of the app, but if your browser is crashing (it looks like so from the data visualization issues) too, there's nothing guaranteed. How big is your video file? I have seen crashes on gyro streams of the GoPro Fusion footage (which are way larger than anything else, maybe Max's are similar). But most data rates on the H8 should be similar to the 7 (or the 5 really).

I have an app in mind that would improve the GPS location data by interpolating missing values, asking the user which sections look right or wrong, setting offsets... I might develop that next year depending on how things go.

"Speed of light, i'm coming!!"

 

My last footage... so ridiculous values... not a meter is exploitable on this roadrun.

 

From the abyss with my little Clio!!

I'll send you the cloud link to dl this footage.

Various. And how big is video file supposed to be to include accelero and gyro? Hero8 splits files to 4GiB so can't be more than that.

Re: Hero 8 / GoPro Max Telemetry

The reason I was asking is that crashes can happen easier with large files. But anyway, the problem is that last weeks firmware update introduced changes in the way telemetry is stored, including some tricky ones. I have just updated my online tool and now it does not crash with your footage.

Regarding GPS data, I see your video was filmed from inside the car, under the roof. Unfortunately you cannot expect good results there. The GoPro does not have a cellular antenna to complement the GPS data with land-based data, so you should either put it under the windshield, or outside for good results.

Re: Hero 8 / GoPro Max Telemetry

Glad to have contribute to make your app better. I confirm Accelero and Gyro now loading! Thank you for update @kajuna .

 

About the camera placement. Of course, i guess under the windshield it's better, but the render will not so interesting than POV. When i started from the heights to the starting point of the footage i sent you, all the signal is ok (not perfect but no big aberrations). I think the quality signal at start point is the cause of this epic fail, more than the roof.

Re: Hero 8 / GoPro Max Telemetry

Hi

I need to accurately sync telemetry data with video frames. On Hero 7 the GYRO stream does not have STMP stream. just wonder if time stamp is provided in Hero 8?

 

thanks

@hosseina36007 Yes it is
