I'll bet a single camera plus good editing trumps a multi-camera setup.
Boy, there is so little editing that can be done single camera. It's really just removing dead space. I challenge you to show us a single camera aviation video worth watching.
Let us know how it works. I've always been suspicious of the knock off cameras because I think they're old technology. They're knock offs, probably copied by disassembling someone else's camera and reverse engineering it, then filling in the gaps, sometimes badly. Not that I think overseas companies would do that at all, no sireee.
GoPro is an overseas company also, and have the technology mostly right. China can, and does, make some amazing things.
But that wasn't your main point, I get it.
GoPro, in head to head evaluations, always beats the knock offs. They are simply better. Now, whether they are worth the price tag, is a different subject that might vary by individual. But the top of the line GoPro compared to the best of the knock offs (which, BTW, will not be $30, but $200) always has the GoPro winning.
I would be *very* interested in seeing test footage from $30 knock offs that people think are great. I occasionally do have situations where I want to put a camera in places where it might be broken and having a camera cheap enough to treat as disposable would be a good compromise for quality in those instances.
Get an ND filter. It'll be imperative if you shoot through the prop disc. Experiment with the FOV settings to see what you prefer.
Get a good camera and take lots of snapshots. You'll enjoy those much more than editing through hours of boring video.
Yes. Yes. Yes. No.
Some people really, really enjoy the editing process. I suspect you are right in this specific instance, since the OP has clearly never done this kind of thing before, but my FIL spends dozens of hours after trips doing editing (and has done so back to the slide-show era) because he loves reliving the trips and solidifying the memories as he documents them. Only family ever watches his videos, but he doesn't care. He's really doing it for the love of the game.
Gopros can be turned on/off with an app on your phone...
I haven't tried it with the current generation, so maybe it's changed, but in the past the app was *not* the way to go. It was just as power hungry as if you were actually shooting video. The way to go was to use the keyfob, which could be on standby literally for days. Can anyone comment on whether that's still true for GoPro 5's or 6's?
