Warp stabilizer strange behavior on timelapse video

[tegumedia]

Hello,

I would like to stabilize a time lapse video, but I have the following strange effect between 8 and 11 secs.
I tried with both of Mercalli v4 (using as default and usually it is working well) and the built in Anti-Shake effect but all of are producing the similar result.
I admit that it is a challenge to stabilize well a timelapse like this where everything is moving, but I am looking for any solution.

I also tried to split into 3 parts the video and ignore the middle (and only stabilizing the beginning and the end separately), but it is a nightmare to find the proper zoom/scaling to join them again.
The Anti-Shake effect supports key frames but it is not working for some reason, whenever I modify one key frame the modified value is applied for all...

Do you have any suggestion to solve it?

Have you tried rendering out the time lapse, and then stabilizing that video?

Yes, I tried on:
- The original video (GoPro6 Timelapse video)
- Exported in h264 format
- Exported in h265 format
All of them have the same results.

I meant you create the timelapse, without stabilization.

Then, you render out that video.

Then you reimport that video into a new project and apply stabilization to it and re-render it with the stabilization on.

That way, you aren't doing Time Remapping and Stabilization on the same source footage.1
