I haven’t edited any video yet from my sjcam m10. I’ve got a Mac mini, so was thinking about using iMovie. Newer macs seem to have thus included for free, but mine doesn’t so will need to buy it for a tenner. No idea if my mac has enough processing power to do this quickly / easily, but will know early next year. Currently off my bike after shoulder surgery.
The cheaper sjcam rip offs maybe as good, or may not. Looking online there are mixed reviews – I think the main problem is you just don’t know what you’re getting. Make sure you order one that has sjcam printed on the front – lots call themselves sj4000 in the eBay ad, but none of the ripoffs have sjcam printed on them. Note the box the camera comes in has a scratch off panel so you can verify it is geuine on the sjcam website.
I broke the on/off button on mine – and for $10 sjcam repaired it – I had to send it back to China. That $10 seemed to be partly for postage do seemed fair. They even gave me an extra battery when they sent it back.
