Hey everyone.  Been encountering issues trying to film timelapse videos with my Inspire2 & X5S camera.  Even on a windless day, full GPS signal, fresh IMU and compass calibration, the craft seems to make adjustments on its own while in the air every 30 seconds or so.  I have tried this process in many environments and the results are always the same, regardless of having camera in free or follow mode and even when setting the controller down on the ground so as to ensure nothing is getting touched.
Stabilization software does not fix these problem because the image perspective actually changes.  Please see the following video test and let me know if there are any tips, tricks, or suggestions for filming aerial timelapse.  Thanks!

I would use one of the stabilizer plugins such as you'll find in premiere

The clip you can watch here is using the stabilizer plugin.  the movement is too severe for the plugin to fix

Which plugin are you using....warp stabilizer that comes with premiere...or mocha?

Warp stabilizer. Do you think Mocha would fix this issue?  It looks to me like something more than simply camera wobble.  It looks like the camera is like moving and warping and distorting every 30-60 seconds.

It's not reasonable to expect that the UAV will remain perfectly still and stable over that long a time frame - they are good, but not millimeter perfect.
What I have seen people do is capture the timelapse from a moving perspective which seems to work better, but of course is a very different shot.

it is tough to say without seeing the original clip.  I would try atti mode...and manually correct.  Shoot wider than you need for your frame to account for the scaling that will happen in post. I would shoot cdng as h265 can jello on its own due to the compression.  And yes, if warp stabilizer doesn't work well I would try mocha.

Are you taking a series of photos and combining them or did you take a long video and compress it in the timeline?

I agree, but I don't think that is the problem here.  It appears that the camera is nearly rock solid for 20-30 seconds at a time, then suddenly warps and jerks, then the process repeats.  I have a lot of experience stabilizing handheld shots where the is constant movement and they are generally more stable than this.

It almost looks like the whole image warps in an out, like there is some kind of image decode (lens correction?) happening inside the camera as it is recording.  Perhaps there is a setting that turns on and off a lens distortion correction inside the camera?

It was asked before, but could you confirm whether this is a time lapse made out of a series of stills or from increased video speed? What were your camera settings for this particular video?

Sorry I didn't answer this earlier.  This is a 4 minute video clip shot h264 d-cinelike 23.976 fps with the X5S camera on an I2 in tripod mode.  For this particular clip I used warp stabilizer in Premiere Pro on the entire clip, then exported and sped up that exported file to create the timelapse.

I have tried filming this in sport mode, free and follow modes with camera, manual and auto focus, the DJI stock lens as well as Olympus 25mm, with and without balancing rings, with and without ND filters, etc.
The results are basically the same every time.

I have also tried almost every type of stabiliztion - before and after speeding up the clip, set to still/no motion as well as "smooth motion", etc.  I have experience stabilizing handheld camera clips with the same software and had excellent results.

I hope this information helps. Thanks for your attention to this matter and your advice.

Can you post the original clip, without any stabilization in post?
