Short adagio movements (Summer Mvt 2 at 107s, Winter Mvt 2 at 132s, etc.) compress each day to only 3-5 seconds of screen time at 1×. Looping the music N times multiplies the per-day target duration proportionally so the footage is less aggressively sped up and more watchable. - sky-cam.conf: add MONTAGE_MUSIC_LOOPS and per-movement overrides (Summer Mvt2=3×, Winter Mvt2=3×, Autumn Mvt2=2×, Summer Mvt3=2×, Spring Mvt2=2×) - 4-seasons.sh: multiply target_per_clip by loops - montage-mvt.sh: compute effective_duration, use -stream_loop for audio, fix fade_out_start, -t, and post-build duration check - make-finals.sh: multiply target by loops https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ

# 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
