Jimre, I did not use any stabilization in editing... But YouTube added stabilization after upload. I am in media production, so most likely we will add stabilization in After Effects on most shots so I left the yt stabilization on. However, ATT mode does greatly improve smooth movements. One note though, I needed way more room to make turns and movements in ATT mode. Mostly because the best looking turns are slower and more subtle, so the turning radius goes way up. Got a lot closer to some trees than I wanted too. Whenever it got sketchy I just threw it back into GPS mode and got her back under control and started the shot over.
