sky-cam.conf:
- SCRIPT_DIR auto-detects from its own location via BASH_SOURCE — no manual
path entry needed after bootstrap; override still works via environment.
- BASE_DIR defaults to \$SCRIPT_DIR/data; MOVIES_DIR defaults to \$BASE_DIR/movies.
Override either to point at a drive/mount as before.
- SCHEDULE_SUNRISE changed to 03:00 — the script now waits internally until
the capture window closes before touching images, so the schedule just needs
to be early enough, not timed exactly to sunrise.
- Schedule section rewritten to explain what each job does and what day's data
it processes (SEASONS/FULLDAY always process yesterday).
- SUNRISE_PRE_MIN/POST_MIN comments explain the window and its relationship to
SUNRISE_TARGET_SECS.
- SUNRISE_OVERLAY_ENABLED=true added; set false to skip the timestamp entirely.
daily_sunrise_video.sh:
- After calculating the capture window, sleep until end_sec+30s if we fired
before the window finished — guarantees all images are present.
- DT (drawtext filter) is only built when SUNRISE_OVERLAY_ENABLED=true.
- Step 3b skips ffmpeg entirely when overlay is disabled, moving work_video
directly to final_video (faster, no re-encode).

daily_sunrise_video.sh: use \$MOVIES_DIR instead of \$BASE_DIR/movies so the
override in sky-cam.conf is respected when videos live on a separate drive.
capture.sh: default camera name falls back to \$SUNRISE_CAM (not the
undefined \$CAM_NAME) when no argument is passed.
sunrise2mm.py: also loads .env after sky-cam.conf so Mattermost credentials
moved to .env are actually visible to the upload script.
sunrise.py: raise a clear error message when LATITUDE/LONGITUDE/TIMEZONE
are missing from sky-cam.conf instead of an opaque KeyError.
4-seasons.sh, montage-mvt.sh: capture season_info.py output before eval so
a Python failure exits cleanly with a diagnostic message rather than
silently continuing with undefined variables.
bootstrap.sh: add system package install step (ffmpeg bc fonts-dejavu) and
show the .env setup step after install.sh generates .env.example.
README.md: correct Python package names and add fonts-dejavu dependency.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
daily_sunrise_video.sh: derive CAM_NAME from $1 (defaulting to SUNRISE_CAM)
instead of an undefined variable; this was causing empty image/output paths.
install.sh: pass $SUNRISE_CAM as argument to daily_sunrise_video.sh so it
matches the pattern used by every other per-camera script.
sunrise2mm.py: use SUNRISE_CAM config key (not the undefined CAM_NAME) to
locate the output directory; fixes silent path mismatch on non-default names.
4-seasons.sh: remove stray `set -x` that was flooding systemd logs with
shell trace output.
README.md: correct Python dependencies from `ephem` to `suntime pytz` to
match what sunrise.py actually imports.

Each stage can now fail independently, giving four upload paths:
audio+overlay, audio-only, overlay-only, or speed-only video.
Step 3a copies the video stream (no re-encode) when mixing audio,
so step 3b failure still leaves a clean audio-mixed file to promote.
Overlay failure notification now reports which quality was uploaded.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
daily_sunrise_video.sh: priority chain is camera mic → library random MP3 →
overlay-only → sped video promotion. If audio mixing fails a warning
notification fires and the script retries with overlay-only so a video is
always produced and uploaded.
download-sunrise-sounds.py: downloads CC-licensed ambient sounds from
freesound.org into 11 weather/season category folders (~275 files total at
25 per category), writing a manifest.json with attribution data.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
Removes dependency on MotionEye or any NVR software. Everything is now
CLI/ffmpeg configured entirely from sky-cam.conf.
capture.sh
Long-running systemd service (one per camera) that pulls frames from the
camera's RTSP stream at CAPTURE_INTERVAL seconds, writing HH-MM-SS.jpg
into BASE_DIR/<cam>/YYYY-MM-DD/. Restarts at midnight for the new date
directory; auto-reconnects on camera disconnect.
sunrise-audio-capture.sh
One-shot service triggered at 03:00. Waits until (sunrise minus
SUNRISE_PRE_MIN minus AUDIO_PRE_BUFFER_MIN), then records the RTSP audio
stream for the full sunrise window. Output deleted after mixing.
daily_sunrise_video.sh
Step 3 now mixes in sunrise-audio.m4a when AUDIO_ENABLED=true and the
file exists. Audio is centred on actual sunrise time at natural speed
while the video plays as the sped-up timelapse. Uses filter_complex
when audio is present (can't combine -vf with -filter_complex).
install.sh
Generates sky-cam-capture-<cam>.service for each camera with CAM_RTSP_<cam>
set, and sky-cam-audio-capture.{service,timer} when AUDIO_ENABLED=true.
sky-cam.conf
New settings: CAM_RTSP_<cam>, CAPTURE_INTERVAL, AUDIO_ENABLED,
AUDIO_PRE_BUFFER_MIN, CAPTURE_AUDIO_BITRATE.

Sunrise:
- Overlay failure no longer exits 1; the speed-only video is renamed to the
expected final path so OnSuccess still fires and the upload still happens
- sunrise2mm.py now notifies on every upload outcome (success, post failure,
file-not-found) via notify.sh so the user always knows whether the video
reached Mattermost
Montage:
- Music+overlay failure no longer exits 1; the sped video is promoted to the
*-Montage.mp4 path so year-end-join can still include this movement (as a
silent, no-overlay clip) and the user is notified of the degraded output
- Year-end join trigger is now outside the success/failure branch so it fires
in both cases
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
Each pipeline now saves intermediate files permanently before the step most
likely to fail, so a partial failure leaves a recoverable artifact:
- daily_sunrise_video.sh: speed-adjusted video (*-sped.mp4) survives if the
drawtext overlay step fails; deleted automatically on success
- montage-mvt.sh: speed-adjusted video (*-Sped.mp4) survives if the
music-mux + attribution overlay step fails; deleted on success
- 4-seasons.sh / montage-mvt.sh / year-end-join.sh: explicit ffmpeg error
handling with targeted notify.sh calls naming the failed step and the
surviving artifact path
- montage-mvt.sh / 4-seasons.sh / year-end-join.sh: clip-duration-sum vs
music-duration drift check warns when cumulative float error exceeds 2 s
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
daily_sunrise_video.sh:
- Fixed: was using undefined \$MOVIES_DIR (now \$BASE_DIR/movies)
- Fixed: sunrise_overlay.py was called but never existed — would fail daily
- Fixed: speed-adjust step had no explicit codec (-c:v libx264 missing)
- New: sunrise time overlaid as stacked vertical characters on the right
side using ffmpeg drawtext — no Python/Pillow dependency
- New: upload removed from script; now triggered by systemd OnSuccess=
- Combines speed-adjust and overlay into one ffmpeg pass (was two)
- SUNRISE_OVERLAY_OPACITY from conf controls transparency
install.sh:
- sky-cam-sunrise.service gains OnSuccess=sky-cam-sunrise-upload.service
so upload only runs when video creation succeeds, with separate log
- New sky-cam-sunrise-upload.service runs sunrise2mm.py
sunrise2mm.py: add shebang + chmod +x so systemd ExecStart= calls it directly
sky-cam.conf: add SUNRISE_OVERLAY_OPACITY=0.45
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
Adds six CRF vars, AUDIO_BITRATE, and three MONTAGE_* overlay durations.
Values match previous hardcoded defaults so behavior is unchanged.
The same CRF appeared in several scripts but with intentionally different
values per purpose (28 for draft intermediates, 26 for polished output).
Each script's CRF is now its own variable in conf, so changing one never
silently changes another.
