I'm making a time lapse video. Due to the specific circumstances, the camera is shaking a little when taking the time lapse photos, which is slightly noticeable in the video. In order to remove the shake, I'm using warp stabilizer effect in Adobe Premiere Pro, which works very well.

In one scene, the primary object—a flower—is shaking under the effect of the wind: this movement is expected. What should be still, on the other hand, is the background: a field and some trees which are far enough from the camera for the wind effects to be noticeable.

However, warp stabilizer imagines that it's the object which should be stabilized, meaning that once the effect is applied, it's the background which is now moving relative to the object.

That creates a very weird, crazy looking scene, but aside its artistic value, I want warp stabilizer to focus on getting the background still, while letting the foreground object move because of the wind.

How do I tell warp stabilizer what zone should not move in the final video?

If warp stabilizer effect doesn't have this feature, how can I help the effect to get it right if I have to shoot the time lapse again? For instance, would it help to include a ruler in the photos as a reference of a stable object (the ruler then being cropped after applying warp stabilizer effect)?


You'll need to do this in After Effects, using the Tracking feature, where you add tracking points to specific points and then it crops in a bit and does the same magic.

The issue with your footage is going to be the fact that your background is outside of the hyperfocal, by far. So I can't see even AE being able to track that.

To solve, for your next shoot, put a stick in the ground, with a dot, like a piece of bright spike tape.

Then mat it out in post.

But Premiere won't do this well, and because your shot requires the background to be stabilized, which is a total blur, it's going to be tough, if not impossible.
