Fresco timelapse modifies canvas size constantly

In iPad Pro 11inches M4 when I try to export or preview Timelapse the app constantly modifies the canvas size, with a black frame. It does not allow to save video. Only to files, but fails when try to "save video". I tried all options around: updated iPad and fresco to last versions, changed canvas size, tried several things and nothing works. The Timelapse option it's just broken.
