Add resize-temps.sh — re-size backup temp files to correct movement targets
Re-processes *-temp.mp4 files from a backup location using season_info.py to compute the correct target duration per clip (music_duration / DAYS_IN_MVT), producing properly-sized *-final.mp4 files without touching the backup source. Skips finals that already exist. Fixes drift caused by old pipeline sizing clips to the wrong movement structure. https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ

# resize-temps.sh — re-size *-temp.mp4 files from a backup location into
|
||||
# correctly-proportioned *-final.mp4 files for use with montage-mvt.sh.
|
||||
#
|
||||
# Reads source temp files from BACKUP_ROOT (never modifies them).
|
||||
# Writes finals to MOVIES_DIR (from sky-cam.conf / .env).
|
||||
#
|
||||
# Usage:
|
||||
# ./resize-temps.sh --cam <camera-name> <backup_root> [--dry-run]
|
||||
#
|
||||
# Example:
|
||||
# ./resize-temps.sh --cam east /home/user/drives/data2/other-pictures/longterm/movies/movies
|
||||
# ./resize-temps.sh --cam north /mnt/backup/movies --dry-run
|
||||
#
|
||||
# The backup_root should contain the old season directories:
|
||||
# <backup_root>/<cam>/Spring/ Winter/ Summer/ Autumn/
|
||||
# with files like: 2025-06-15_Mvt2-temp.mp4
|
||||
#
|
||||
# Output goes to:
|
||||
# MOVIES_DIR/<cam>/<ASTRO_YEAR>/<SEASON>/Mvt<N>/<date>_Mvt<N>-Day<D>of<T>-final.mp4
|
||||
#
|
||||
# Already-existing finals are skipped (never overwritten).
