Video produced with AVCaptureMovieFileOutput is different than preview layer at high zoom factors when stabilization is turned on
I've noticed that when using an AVCaptureVideoPreviewLayer zoomed very far in (videoZoomFactor ~130) while also enabling either standard or cinematic video stabilization, that the preview is very different from what's present in the asset created with AVCaptureMovieFileOutput. The movie file is always offset much higher than what I was focusing on in the preview layer.This doesn't happen when stabilization is off, and it happens even when on a tripod (hence the only movement is the act of zooming itself). I'm not sure if this is a bug or something expected with stabilization on, but I would have expected AVCaptureVideoPreviewLayer to be a relatively accurate representation of what I'm recording.Is this a bug, or something I should be able to correct for? Is there some inherent innaccuracy in AVCaptureVideoPreviewLayer?
