Per-camera capture interval: CAPTURE_INTERVAL_<cam> in sky-cam.conf overrides the global value for a specific camera. capture.sh and 4-seasons.sh both respect it. Example: south at 30s saves storage; north at 5s gives smoother motion. 4-seasons.sh one-frame bug fix: Same root cause as the sunrise scripts — concat list had no 'duration' entries, collapsing all JPEG frames to timestamp 0. Fixed by writing 'duration INTERVAL' per frame. Added fps=25 to the speed-adjust step so the VFR source resamples to a standard frame rate. ambient-record.sh (new): Continuous AAC recorder for natural sounds (birds, rain, wind). Saves AMBIENT_CHUNK_SECS chunks to AMBIENT_DIR/<cam>/YYYY-MM-DD/HH-MM-SS.m4a. Reconnects automatically on stream failure. Rolling retention via AMBIENT_RETENTION_DAYS. Enabled by setting AMBIENT_ENABLED=true and listing cameras in AMBIENT_CAMS in sky-cam.conf, then re-running install.sh. https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
