— SMART FRAMING —
Vertical Converter uses Apple's Vision framework to automatically detect and follow your subject throughout the video. It tracks multiple people simultaneously using IOU tracking, identifies the main subject even in group shots, and applies smooth EMA-based camera movement so the result looks natural — not robotic.

Preserve your HDR footage as-is with HDR Passthrough (HLG / PQ / BT.2020), or convert to SDR with Natural (Rec.709-faithful) or Cinematic (ACES filmic) tone mapping.
