The configuration I had the pole set up as wasn't the best. It is designed to be used with fixed window cameras so has a bend in the stick. I've since removed the bend and replaced it with the Insta360 One X selfie stick and am hoping to try some different angles and dangles later today with it. Unfortunately the app isn't very helpful when it comes to editing currently. I am tempted to buy a high end tablet as having a larger screen will help as will a bit more memoryThe live view I can see on your phone looks a better angle than whats in the video.
Make it look like it does a better job in portrait view.
