gauges not available on clip...but on entire chapter [ New ]

[robert1326]

hi,

GoPro 9 on firmware 1.5

iPhoneX

IOS 14.3

GoPro app ver 7.3

with the new firmware GPS measurements are 100% correct on hero9.

when I add the gauges in my iPhone GoPro app, I have this issue, depending on the procedure.

clip oriented:

- I clip the chapter before download

- download the clip only on iPhone

- edit, add gauges - no gauges available 

chapter oriented:

- I download the entire chapter on iPhone - time and space consuming conpared with the previous clip oriented

- edit, add gauges - all good

- clip the interesting part

- save - all good, chapter present

is this an issue, or a feature?

thank you,

robert

Hi Robert,

Sooooo this thread is long but we are seeing the end of the tunnel.
We got your file, we tested on 7.3.2 and have a repro of the issue.
HOWEVER, I just tested on 8.0 and I was able to trim your video 4 times and had no issue adding stickers, the option was still available.
So whatever is happening here, it's fixed in 8.0 coming up this month :)

Best,

hi,

few days ago the 8.0 (the new Quick) became available.

yes, works.

thank you @haindash 

have a good one!

Hello @robert1326. Thanks for the details. Just to check, do you also get the same results with non-chaptered clips, for instance, a 3 minute or less video? Or is only observed on chaptered clips?

[robert1326]

hi @aenriquez 

yes, same.

a 6:52 non-chaptered footage*, and a 2:44 clip from this footage.

when I'm trying to add gauges, works only for the entire footage, not for the clip.

thank you!

robert

*at 4K25fps the chapter starts after 8:51

As far as I know this is normal. Trimming a video has always deleted its telemetry

hi @kajuna , @aenriquez 

thank you.

I'm pretty sure that back in hero7, hero8 I was clipping only my downhills with my MTB from the footages, and after apply the gauges..... but I could be wrong.

I sold my hero8  so I cannot test it.

not a big deal... as I said is an issue or a feature....

have a good one,

robert

Hi,
So I tested on my end - short 45 sec 1080/60 HERO9 videos with GPS data.
- Adding GPS stickers on full video is working.
- If I trim keeping only the beginning then on this part of the clip I can’t add GPS stickers
- however if I trim but leave out the beginning and start like middle to end, then I can add the GPS stickers.

My guess here is that it's related to reliability of GPS data, the beginning of the video is when the accuracy of the GPS isn’t the best, the GPS lock may be be complete and data are not accurate enough to use GPS stickers.
However the rest of the video has clear GPS data hence it will work if you leave out the beginning and trim later in the video.

Could you test that use case on your end as well? Preferably not on a huge chapter video, it will make things easier.

[robert1326]

hi @haindash ,

ok let me try.

keep in touch,

robert

[robert1326]

hi @haindash 

I have a full footage ~9.5 min

and clips from beginning, middle and end ~1min each.

I extracted the EXIF from all.

all these four files have all GPS Measurements 3-Dimension rated -  see below.

however, in the phone app, only the full footage gets the GPS gauges, as I said.

hope this helps,

robert

if you look at my diggings, the telemetry is there.....

Hi Robert,

Thank you for sharing this information.

So, just so you know - the GPS data useful for the stickers is inside a GMPF track, not the EXIF metadata. The EXIF GPS is recorded at the beginning of the video and copied/pasted in the various trims that you do - whereas the GMPF track is trimmed according to the video trims.
If I understand correctly, what you checked is the EXIF part, not the GPMF part, we can check that part.

We have two hypothesis here:
- Either the places where you trimmed your video had unreliable / too low GPS precision data and that's why you couldn't apply stickers, you were really unlucky because it was for the three trims you made :(
OR
- something in the GMPF track got broken when you trimmed.

Could you send me (dropbox or else) the trimmed parts?
I will test this as well on my end.

[haindash]

@robert1326
Hi Robert,

I did my test on a 9:33 video (HERO9 / 1440p/50fps) I could apply GPS stickers.
Then I trimmed it 4 times at 4 different places (beginning, middle, end) I was able to add GPS stickers to all trims.

My video was 9:33 and not chaptered - chaptering depends on file size and my video wasn't chaptered.

Don't hesitate to send your trimmed parts so we check the GPS precision on those.

[haindash]

Hi,

I did some more testing, this time with a chaptered video - filmed for a long time, ended getting 2 videos. Both I could apply stickers, trimmed the videos, I could still apply GPS stickers.
However the first chapter video test I made, I couldn't, the only reason I can find is that I had started recording in a spot where GPS reception wasn't reliable, because on the second test, at another spot, it was ok.

hi @haindash 

sorry for the dealy. caught in a demanding project.

thank you for your tests and support (not only on this challange).

I sent you a message with a link for downloading the files.

thank you,
