// HandBrake 1.11 gemessen haben:
//   --help         → Encoder-Block „-e, --encoder" bis zur nächsten Option
//   --preset-list  → Preset-Namen mit genau vier Leerzeichen Einrückung
//   --scan --json  → „JSON Title Set:" + Objekt + „HandBrake has exited."
//   Encode         → „Encoding: task 1 of 1, x %" in Stufen, Datei kopiert;
//                    ab der zweiten Stufe mit der fps/ETA-Klammer, wie das
//                    Binary sie formatiert (5.6.0, Restzeit).
