Here's my new video filmed with my friend's Phantom 3, the Sony RX100m3 and my Osmo. To be honest, most of the footage is with the Sony, since it was static shots - however, there's a pretty long walk I did with the Osmo which was sped up to 350%. Despite i'm happy with the result (much better than anything out of a gopro or non stabilized camera), i'm wondering whether I should invest in the Z-Axis. Or just improve my Ninja walk? Thought it was already pretty decent, but perhaps I was walking too fast in this shot. Best thing to do, when possible, is film while on a scooter.....

Hi, when you speed up the video, it's inevitable the video will look like bobbing, because the vibration is magnified.  I suggest you try the z-axis stabilizer, since you can always return it if you're unsatisfied.

BTW, it looks strange when you put the subtitle on upper right corner, I didn't notice it at first. Also, the fonts of the Chinese characters could be modified to look nicer.
