Use the illustrated first frame. Fixed side camera, fixed floor and background blocks. The single teal cylinder rolls slowly a short distance toward frame right on its curved side. Its center moves right while the pale radial stripe on the visible end turns clockwise. Keep the cylinder's diameter and end-face identity stable. Its lowest edge remains in contact with the same flat floor; no bouncing, hovering, stretching or camera tracking. Slow down to a stop and hold at the new position. One roll, one continuous shot, no full revolution required.
