Cameras can be calibrated between models, using TCAL metadata. Timecode precision is generally within a 30fps frame if the camera remains on. If the camera turns off, the frame precision is lost, but the second precision remains. This is why in your testing you saw a range 0.5 to 1.5 of error. If is was the same camera model (without calibration) the error would be +- 0.03 (frame error) and +- 0.5 (1 second) when powered off.
Thanks for explaining it. At this point the second precision is managable and the weak link in my fishing setup is my insta360 X3. I am hoping GoPro has a new 360 camera out soon that might be a good replacement since it might also support this time sync. I don't dare buy the current max where September historically seems to be GoPro release month.
I just set my gopros to HDR for a fishing trip yesterday... It ruined the footage. HDR from the Hero12 is a contender for reddits /r shittyhdr group... Shadows are boosted TOO much and highlights being brought down adds ugly halos around dark stuff and it looks so fake. That feature is a gimmick for normal use.
@@mainelyhobbies mine froze up (picture freeze) up in Alaska on a dog sled adventure. Ruined. Now using osmo action 4 and it can be jam synced via timecode.
Insta360 cameras have been rock solid for me as well... Somehow the insta360 X3 is able to record 5.7k 360 video with stablization for 6 hours straight and not overheat at all.
I don't know if you have tried to sync the X3 since this video was made but if you have I'm sure you notice that the X3 has gaps between "Chapters" of 11 to 15 seconds. This is unacceptable for long duration recording. None of the GoPro HERO cameras have these gaps.
@@mainelyhobbies I'm curious do you have a video where you show the drift for hero 12 cameras? Also It's strange the drift increased and then decreased again. It makes me think it's probably because they have a non temperature controlled oscillator. Perhaps if you just leave both cameras recording they will both heat up roughly the same and have a consistent drift rate. I'de be curious if that's the case.
good job brother, you tackle the topic straight forward. yes please try syncing the Insta 360 as well that would be more interesting. looking forward

@@mainelyhobbies MAX does support time sync too. ;)
Ahh but I just found out the MAX doesn't support loop recording so it becomes useless for fishing :( I can't win on the 360 camera for fishing.
@@mainelyhobbies Without looping you can record more than 8Hours in 256GB card.
Your advice is a lifesaver. I've been tearing my hair out over these GoPros, I am using GoPro 9, 10 and Max 360 @0dan0
This is a great example of why not to use the GoPro for anything critical, it will always let you down.

I usually use loop mode but yes I noticed the same after 30 minutes it creates a gap and starts a new file.
I tried this with three GoPro 7 cameras and one of the three was as much as .5 seconds off from the rest.
Exaclty my experience until i switched to hero 12s.. those stay in sync.
