Gimbal transition upward instead of downward / Bucking stuttering behavior
I'm new to Dronelink, but am enjoying it so far. Thinking out a course then previewing in Google Earth is raising the ceiling for the sorts of complexity I would want in my drone shots. Very nice.
I have two questions resulting from my first full day of trials. In case it's relevant, this was with a Mini 2.
1.
Sometimes, the drone goes into a start-stop behavior, not at all smooth. This "bucking" is not the Mini 2 being blown in the wind; it doesn't happen under DJI Fly and it's a calm day. It's not a stuck gimbal, as I can watch the drone starting and stopping in the sky abruptly and repeatedly.
See this video for an example of what the gimbal can't compensate for. https://drive.google.com/file/d/1ehNycT2P3-jxbb-y2TMUD1xYwQJYovsw/view
The FAQ mentions a substandard tablet as being a cause of this sort of thing, processing power, etc. It's an old Galaxy Tab A2 so it wouldn't surprise me that I'm pushing its limits. Does this seem like the sort of thing that a slow tablet could cause?
2.
Check out this video, which is a transition from one point of interest to another. It's not at all smooth, pointing downward then snapping back upward. The other POI transitions are much nicer, but this one just isn't. Any ideas how I can smooth it, make the gimbal take an upward path instead of downward?

In my project https://app.dronelink.com/greg-allensworth/my-first-project/plan/KPvE79yi5kquMUBeHGKQ/FB2wx3BvGGHhgiTMvYHQ this is the transition from Marker 3 to Marker 4.
All told, I'm impressed with DL's potential and am looking forward to smoothing out these bumps and continuing to explore.

A slow device can cause issues. With that said, the only thing I see is you placed two POI markers, 4 and 8 on POI “E”. But you have other markers with POI’s in between them. At least it’s possible from what I can see. Try changing that and run again. I don’t know it a previously tied together POI effects the other ones or not. You can also add a marker with a gimbal pitch in between if wanting it go up less or more before next marker/ POI so it doesn’t go from a step negative pitch to 0°. Should not need it though. Hope this helps.
Thanks for the tip, Mike. Removing and changing marker 8 didn't change anything, but I did find a workaround.
In between marker 3 (facing the farm) and marker 4 (facing the hilltop) I added a new marker, facing about 90 degrees between the two and with a +200 elevation. In the preview, it now pans from the farm to the middle distance to the hilltop in a smooth arc.
The issue was that the two POIs were about 180 degrees apart, so it switched facing from one to the other picking the shorter path (down). With the intermediate step, it's unambiguous.
Very neat, is that the DL preview DID include this undesirable facing behavior and I just didn't give it mind at the time. So tomorrow I'll go run it, and I'm sure it'll act how I want now.
Yep, I didn’t check the altitude off-set. Sounds good. 🤙🏼
This is exactly the issue
