I had issue with inspire 2 and x7 since i bought, it was sent to DJI for repair and came back with the same issue:

Again they send me the below and all is done and some instances its not the case,

Check my recent shoot with the same issue , any thoughts? https://we.tl/t-eURdo9Vh4P

1. Check the wind speed: If the wind speed is too high, it will cause the jelly issue. It is recommended that the customers change the environment or fly the drone at another time. (The aircraft can withstand 10 m/s.)
2. Check the control stick operation: If the control stick is strongly pushed, the aircraft flies at high speed, and the jelly issue occurs. In this case, guide the customers to operate the control sticks gently.
3. Check whether the vibration absorption board or rubber damper is damaged. If yes, replace it.
4. Check the firmware. If it is not the latest firmware, update it.
5. Perform the gimbal self-check, reset the gimbal parameters, and calibrate the IMU.


Thanks
Bachir

Bachir, I am sorry for the trouble. For the video you provided above, it was not able to download, when I clicked it, it jumped to a page indicated the page not found. Could you please upload the video again to Dropbox so we can check more details about the issue of your Inspire 2? Thank you.

Hello Bachir, thank you so much for getting back. I'd checked your video, but it doesn't seem to have the jelly issue. Could you please try another player or play the video on another computer?
Besides, please kindly provide us with the case number of the repair so we can check more details on the system, thank you.

When I looked at your footage I did not see any "jello" effect, rather the fast forward flight and the camera pointing down creates a skipping motion which isn't uncommon for such a shot. In film camera this is avoided using global shutters (rather than rolling shutters).
Also keep in mind that such a way of shooting, looking straight down while flying fast forward will generally by unpleasing to look at.

Next thing to consider are micro vibrations, the X7 is quite a long, so if you point it straight down and fly forward, you basically create a decent amount of wind drag on the camera itself, this could also cause some micro stutters.

Hi Sonic,

Thanks for your reply,

I do understand the part that its unpleasant to watch, but its asked by my client which i cant avoid the request.

So you advise the best way to do it is at max 20km/h speed for look down shots on the X7? this is the only solution correct ? i can share more footages with this effect which i have on my library, some of them are not look down ,,, some panning as well left to right etc
