I went for a paddle today with my GoPro Hero 5 Black, and in spite of carefully attaching my Novabeam USB battery, I only got 95 minutes from it, just as if I hadn’t used the battery. Meanwhile, I had the GoPro Hero 5 Session at home doing an experiment where I’d hooked up another Novabeam USB battery, and when I came home I discovered it had recorded 4 hours and only stopped because it had filled up the SD card.
But then I tried just unplugging and re-plugging the Novabeam on the Hero 5 Black, and it happily started recording. I suddenly realized that a light comes on in the Novabeam when you first plug it in. And it struck me that one significant difference between my “bench tests” on my desk and my tests on the water is that in both cases I plug the USB battery in and arrange the silicon putty here at my desk in both cases, but in the “bench test” I hit the Record button almost immediately, while for the water tests I first drive 20 minutes. I bet the battery is turning itself off in that time.
So next time I go paddling I’m going to have to try plugging the battery in and waterproofing it just before I hit record. If I can get 4+ hours of the battery, I can do that early in the pre-paddle preparation and still get the whole paddle or race. I’m so happy that I have probably figured this out before my first race.
Did some more work on technique. I took my front camera, my Motionize setup, and an idea of trying some different paddle lengths. So first off, I started off at my normal 214cm but with a tiny bit of pause to drive the paddle in before I start pulling and a mental emphasis on the catch. That actually seemed to help a lot. Then I tried some different paddle lengths. I have to say that I discovered some things:
With the GoPro mounted on my lovely Jim Smith bow mount, I took it out on the Genessee River to see how it looks. And I have to say, I think it looks awesome (ok, as I write this it’s only a few minutes after I uploaded it to YouTube and YouTube is only showing it in 360p, but trust me when I say it looks great in 4K). The GoPro doesn’t have image stabilization in 4K, but on a flat water trip like this, it doesn’t need it. And I love the position – the Jim Smith mount puts it just at about the right height, and it feels firm.
I’m going to update this table as I do further tests. These are “bench tests” done with the camera mostly stationary in my office or in my work-out room. The idea was just to get a basic idea of whether I’m going to be able to record long kayak races with the camera as-is, or if I’m going to have to figure out how to attach an external battery to it without compromising the waterproofness.
|External Battery||Battery Life|
|4K/30||On||Off||NA||Yes||142 min overheat
– card filled up
One additional test: I wanted to see whether being in “standby” mode using a remote consumed a lot of battery power, because if not I could perhaps cover a long race by turning it off and on as action warranted. However, in 4K mode (where I got 92 minutes video in continuous shooting), going 30 minutes on then repeating 15 minutes off and 15 minutes on, I only got a total of 111 minutes total between shooting (66 minutes) and standby (45 minutes). That’s not what I was hoping – basically 45 minutes in standby was equivalent to 26 minutes running.
Note: The “External Battery” in the table is a Novobeam NBP3000 Waterproof USB battery. I’m trying to figure out how to attach it to the camera without compromising the waterproofness of the camera, possibly by covering the USB and HDMI port hatch with Sugru or something similar.
