revvhappy Posted July 2, 2021 Report Share Posted July 2, 2021 My Google-fu is failing me this morning, so it's time to ask the pros... I just purchased a Gopro9 black and would like to capture 8 hours of continuous footage. I purchased a 256gb card and set the camera at 1080 (I don't need slo-mo). I also added an external power source (usb) with waterproof case. Can anyone help with setting this up to turn on automatically when the external power comes back on after a pit stop? Or transition between battery and external power to keep the camera running for the entire race? I'd also be interested in your video settings. One final thing... I used this during a test day and found that video is captured in 9 minute chunks and not a large file. Is it possible to capture one large file or do you just have to put it together with a video editor? TIA 1 Quote Link to comment Share on other sites More sharing options...
petawawarace Posted July 2, 2021 Report Share Posted July 2, 2021 I don’t know if there’s anything settings wise you can do for pit stops. You could run a separate power source right from the battery just to the gopro. Many sanctioning bodies allow this and I would think if it’s pretty obvious and small gauge wire it should be fine.

TimS Posted July 2, 2021 Report Share Posted July 2, 2021 People use the battery power packs to power camera and car Power to charge battery pack so power to camera is not interrupted. File size is an issue I have with my fake gopro. Camera seems to save small files and then play it as if it was one file. There is some maximum size for these files but I don’t recall what it is.

Bremsen Posted July 2, 2021 Report Share Posted July 2, 2021 (edited) On my 8 black, I had to remove the gopro battery from the camera to run it continuously off the external pack. The 256gb card ran like 12hours at Charlotte. I will also suggest locking the stabilization if you run on a banked track. 50% of my footage at CMS was looking at the floor board. Not sure there is anything you can do about the clips. Mine also saves in 15-20min blocks. Edited July 2, 2021 by Bremsen 1 Quote Link to comment Share on other sites More sharing options...
ross2004 Posted July 2, 2021 Report Share Posted July 2, 2021 I think the max file size is 4GB (used to be, may be larger on the newer ones). You could turn the resolution down to 720 and get more minutes per file. 1 Quote Link to comment Share on other sites More sharing options...
revvhappy Posted July 2, 2021 Author Report Share Posted July 2, 2021 (edited) Great suggestions. If I'm understanding this correctly: Switched USB from my dash to charge an external battery pack, and the battery pack will keep running the camera when the car is turned off in the pits. Bremsen - do you have a photo or link for the external power pack. Edited July 2, 2021 by revvhappy 1 Quote Link to comment Share on other sites More sharing options...
Bremsen Posted July 2, 2021 Report Share Posted July 2, 2021 I can't find my exact one, but similar to this: https://www.amazon.com/dp/B07H7LFPYX/ref=twister_B06XQV5DDP?_encoding=UTF8&psc=1 Its just secured with HD velcro to an aluminum plate. So far I've only run the 8 on it, but didn't have any power/recording interruptions all day at Charlotte 14+hrs. The card finally maxed around 9:30pm. I plan to incorporate my old 3 silver as a rear view and run it on the other port. Quote Link to comment Share on other sites More sharing options...
revvhappy Posted July 2, 2021 Author Report Share Posted July 2, 2021 Wow. I have that exact Anker battery unit sitting right next to me on a table. Thank you. 1 Quote Link to comment Share on other sites More sharing options...
Team Infiniti Posted July 2, 2021 Report Share Posted July 2, 2021 Clip size is adjustable on our gopro3, as for cameras that shut off mid day, check to see if the input power is 1 or 2 amps out of the usb, 2 amp power is too much and overheats. Not sure about the newer go pros but switching to 1amp input power solved most of our issues. (no battery pack go between) 2 Quote Link to comment Share on other sites More sharing options...
thewheelerZ Posted July 3, 2021 Report Share Posted July 3, 2021 ^^^^ This exactly, 1amp charger. We use a trusty hero3. The only failure we ever have is the classic “didn’t press record” failure mode. 3 Quote Link to comment Share on other sites More sharing options...
enginerd Posted July 3, 2021 Report Share Posted July 3, 2021 (edited) Doc did a write up on this subject a couple years ago (or maybe I sent a PM or something), I did exactly as he said and couldn’t be happier with how my system works. Use this battery pack: https://www.amazon.com/XTPower-MP-10000-External-Battery-10000mAh/dp/B00935L44E/ref=asc_df_B00935L44E/?tag=hyprod-20&linkCode=df0&hvadid=312111908612&hvpos=&hvnetw=g&hvrand=16723808528786516356&hvpone=&hvptwo=&hvqmt=&hvdev=m&hvdvcmdl=&hvlocint=&hvlocphy=9021571&hvtargid=pla-524313202289&psc=1 and use a ‘battery eliminator’ (can’t remember which). Plug the battery pack into a charging circuit to replenish charge during the race, and plug the camera battery eliminator into the battery pack so it continues to run during pit stops and will continue for many hours in the event of a failure in the charging circuit. You will need to do some cutting in the gopro case to route the battery eliminator wire. Edit: I use a GoPro Hero3 silver+ your model will likely differ with case and battery eliminator Edited July 3, 2021 by enginerd 3 Quote Link to comment Share on other sites More sharing options...
revvhappy Posted July 3, 2021 Author Report Share Posted July 3, 2021 The 3BR product in the original post is mostly a battery eliminator with the benefit of keeping the camera mostly waterproof. I'll be wiring it exactly as you mention using an external battery like the one Bremsen linked. Quote Link to comment Share on other sites More sharing options...

You could turn the resolution down to 720 and get more minutes per file. File size is dictated by the memory card. FAT32 formatted SD cards have a 4gb file size max, which is why the videos get broken up. 1 1 Quote Link to comment Share on other sites More sharing options...
enginerd Posted July 3, 2021 Report Share Posted July 3, 2021 Keep your file size down by shooting 30fps instead of 60. I tested both and was unable to tell the difference. Of course I only watch the videos in normal speed. 1 Quote Link to comment Share on other sites More sharing options...
