4-seasons.sh: - Fix per-video target duration: divide by days_in_movement (~30) not days_in_season (~90), so concatenated clips sum to the movement's music duration - Force consistent 1280x720 output (scale+pad) to prevent resolution mismatches when montage-mvt.sh concatenates across days - Use ffprobe (not ffmpeg stderr parsing) for reliable duration reading - Add music-dir fallback to repo-local music/ folder - Remove the 2× music-doubling workaround (root cause fixed above) montage-mvt.sh — complete rewrite: - Proper season/movement detection matching 4-seasons.sh logic - Step 1: concat all *-final.mp4 clips, normalise to 1280x720 - Step 2: speed-adjust concatenated video to exactly match music duration - Step 3: merge with Vivaldi movement audio + 2 s video/audio fade in/out - Step 4: generate 7-second black attribution card (drawtext) crediting John Harrison / Wichita State University Chamber Players / FMA / CC BY-NC-SA 4.0 - Step 5: concat montage + attribution into final file - Temp files cleaned up via EXIT trap fullday-video.sh — new script: - Full-day timelapse from yesterday's images targeting ~30 minutes - Per-frame duration = 1800 / num_images (clamped 0.017–10 s/frame) - 1280x720 output, video-only (no audio) - Auto-deletes fullday videos older than 10 days https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
