Yeah, I know you’re getting bored about my GoPro issues

So I found a new waterproof external battery pack for the GoPro. This one used a waterproof case and a gland nut on the GoPro, and a separate battery pack with another gland nut. I’ve been starting to come to the conclusion that the problem with the GoPros shutting down is one of heat. So I was hoping that keeping the battery outside the camera case would reduce the heat build up.

I charged the new battery and attached it to the GoPro with no internal battery in it. I tried setting the GoPro to 4K/60fps and took it out while walking Gizmo, and then just letting it run. It make a strange chime and then shut down after just over an hour. I let it cool down a bit and reset the camera back to 1080p/60fps and (without recharging the battery) got over 3 hours on it.

What I’d really like to do is try it at 1080p/60fps in a more realistic scenario, where things are moving and the image stabilization has to work like it does in a real scenario. Maybe I’ll put it on the oscillating fan and just let it rip.

More on the damn GoPro battery issue

Ok, so I kicked both cameras down to 1080p instead of 4K, figuring it would reduce the heat build-up. And I managed to get the expected 4+ hours out of camera #1. Great!

However, camera #2 is still having problems – it would shut down as soon as I hit record. I tried doing a factory reset, I tried swapping SD cards, but the problem appears to be that it just doesn’t like the sidecar battery. It doesn’t matter which sidecar battery I use – as soon as I turn it on, it turns off. Take off the sidecar battery, and it’s quite happy recording for 100 minutes.

I think for this weekend I’m going to try using the sidecar battery on camera #1, but just going bareback on #2. I’ll probably put #2 on the bow facing back, because that view is usually only important in the first part of the race. When I get home, I’ll see if GoPro will admit there is a problem with their camera, although since it only happens with a third party battery I don’t have high hopes.

GoPro battery problems (again)

I use a “sidecar” battery for my GoPros to get some extra battery life. And when I was using them with GoPro Hero 5s, I was frequently getting 3.5-4 hours of video recording. But at the Round The Mountain race, one of them shut down after less than an hour (I’d turned them both on really early hoping to capture some of the flavor of the start area, and it ended up shutting down when I was warming up). I took them out for another test and I got 99 minutes out of the first and 120 minutes out of the other. In both cases, the sidecar battery appears empty or nearly empty, but there’s plenty of life left in the “built-in” battery. I’m able to turn them on and record another 80-90 minutes after I finished.

I don’t know if it’s an overheating problem, or what. Unfortunately the sidecar requires both it and the camera to be in a clear plastic case, which can’t help with the heat problem. I wonder if I should cover the whole thing in tin foil except the lens area?

Video stuff

I found a really cool Final Cut Pro plugin that puts a motion tracked point on your video and builds out a title that moves with the tracked point. I’ve experimented with it a bit and I think I’ll be able to use it to point out people and other points of interest in my videos. The only problem I’ve found with it is that if the point you’re tracking is even briefly obscured, it will lose tracking and its mind.
