Post subject:  How to motion timelapse in a circle?

I shot a motion time-lapse of a statue completely encircling the statue. When I attempt to smooth out the image sequence in After Effect using warp stablizer vfx effect, the result is a cropped-down image sequence. Need recommendations to re-shoot or change parameters in After Effect warp stabilizer. settins I use are smooth, 100%, stablize & crop,.

Stabilizer is going to crop the image. Imagine your bumping, unstable image rectangle. There is some image in the middle thats in frame all the time. This is what stabilizer can keep and still give you a stable output. At the edges, there will be some parts that drift in and out of frame because of the instability you are trying to remove. This has to get clipped if you want a stable image and no black borders intruding on the image area.

Some programs let you specify not to crop, so black appears at the edges where image was not recorded because those areas were out of frame on those shots because of the camera looking elsewhere.

The best solution is to have less instability so less image gets cropped when you stabilize. That part is not easy.

You could try the "Stabilize Only" setting in Warp. Sometimes that works better for really shaky hyper-lapse footage.

Getting a smooth result is very tricky, specially on circle hyperlapses. 95% of the work must be done during shooting. A good shooting is the key. Always use a tripod if you can. The wider the lens, the more difficult it will be to stabilize and get smooth movement on the edges. The circle must be as perfect as possible. Always point the camera to the same point. Keep the camera always on level. These are the basic points for shooting. I tried a circle hyperlapse shooting handheld (as a test before the real shooting I'll be doing soon), I finished stabilizing it frame by frame, Warp stabilizer gving shitty result but with a good shooting, I think it will work ok. You can also start by a position and rotation stabilization first and just add the warp stabilizer with a small percentage to smooth it all at the end.
