- verify-mvt.sh: remove dead first _info= line (used MVT_START before defined); fix JPEG size loop to accumulate bytes correctly and display human-readable total; show size in delete confirmation - montage-mvt.sh: grep -c uses || echo 0 instead of || true to be unambiguous about the no-match value under set -e - capture.sh, capture-watchdog.sh: require camera name arg, remove silent SUNRISE_CAM fallback - migrate-seasons.sh: require --cam arg, error if missing - README.md, sky-cam.conf: remove stale fullday-video.sh references; README pipeline diagram updated to show verify-mvt.sh https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ

# montage-mvt.sh — compile one Vivaldi movement's daily clips into a montage.
|
|
#
|
|
# Duration matches the movement's music exactly. Attribution is overlaid as a
|
|
# translucent bar across the top of the video for the first ATTR_DUR seconds
|
|
# (fade in/out) — no separate card appended, so year-end joining is a plain
|
|
# concat with no duplicate attribution concerns.
|
|
#
|
|
# Called automatically by 4-seasons.sh on the last day of each movement.
|
|
# Can also be run manually for a mid-season preview.
|
|
#
|
|
# On the last day of Autumn Mvt 3, automatically triggers year-end-join.sh.

# Music: "The Four Seasons" by Antonio Vivaldi
