Scans all *-temp.mp4 files under a backup root regardless of directory
structure, infers camera name from path, uses season_info.py for correct
movement sizing, writes finals to MOVIES_DIR. Handles messy nested paths
(south/south/, movies/south/, etc.) and deduplicates via EXISTS check.

+#!/bin/bash
+# make-finals.sh — one-off recovery script.
+#
+# Scans ALL *-temp.mp4 files under a backup root, infers the camera name from
+# the path, uses season_info.py to get the correct movement info for each
+# file's date, speed-adjusts to the right target duration, and writes
+# *-final.mp4 files into MOVIES_DIR (from sky-cam.conf / .env).
+#
+# Safe to run multiple times — skips any final that already exists.
+# Never modifies the backup.
+#
+# Usage:
+#   ./make-finals.sh <backup_root> [--dry-run]
+#
+# Example:
+#   ./make-finals.sh ~/drives/data2-main --dry-run
+#   ./make-finals.sh ~/drives/data2-main
