yeah this has been bugging me for a while. i built my own 5 inch freestyle rig and i get that fpv is supposed to look a bit raw but my clips look way more jittery than the guys i watch on youtube, even the ones who are clearly not flying smooth lines. i have a gopro hero 10 mounted on a tpu printed tilt mount and hypersmooth is on but it still looks like im flying through a blender sometimes. not sure if its my mount, my pids, or just the way i fly honestly. heres a recent clip from last weekend at the skatepark

anyone see anything obvious that i'm doing wrong or is this just a skill thing i need to grind through

hard to say without seeing your pid tune but that shaky look is almost always either props out of balance or your rates are set too sensitive and small inputs are causing oscillations. the tpu mount helps but if the quad itself is vibrating it doesnt matter. try dynamic filters and see if that cleans things up a bit, worked for me on a similar setup

honestly looked at the clip and i think a lot of it is just stick inputs, you're making a lot of tiny corrections constantly which reads as jitter on camera even if it doesnt feel that way when flying. takes a while to get smooth but thats just fpv, took me like a year before my footage stopped looking like i was having a medical episode mid flight
