Reconstructed from the original build sessions, not from memory. Every script, command and
setting below was recovered verbatim from the June 2026 chat history and is preserved on disk at
/workspace/nursing-videos/recovered/original_scripts/.
The reused, generalized version of this pipeline lives in /workspace/nursing-videos/pipeline/
and was verified by rendering real video (pipeline/README.md).
| film | path | size | verified |
|---|---|---|---|
| v1 — generated stills | finals/calm-in-the-storm-720p.mp4 | 40,090,678 B (38.2 MB) | 122s · 1280x720 · 24fps · audio yes |
| v2 — your clips mixed in | finals/calm-in-the-storm-v2-with-user-clips-720p.mp4 | 40,105,460 B (38.2 MB) | 122s · 1280x720 · 24fps · audio yes |
Both are the same 2:02 film. The difference is only the source material:

footage) and 4 Gemini-generated stills, mixed with generated scenes. Script:
calm-in-the-storm/build_v2.py.
Five other renders from the same period are gone (build folders were cleaned out) — listed on the
archive page. Their scripts are recoverable, so any of them can be rebuilt byte-for-byte from the
same inputs.
Rebuild proof (Sep 2026): v2's scene plan was re-rendered from scratch with the kit below —
pipeline/manifest.v2-reconstruction.json → _smoketest/proof/calm-in-the-storm-v2-rebuilt-720p.mp4,
122.00s · 1280x720 · 24fps · 38.9 MB, i.e. the same film the original 122s / 38.2 MB / 1280x720
render describes. The only deliberate difference: this rebuild has no narration track, because the
original Edge-TTS mp3 lived in ~/.hermes/audio_cache/ and that cache has since been cleared.
Everything starts from one markdown document — `FROM CHAOS TO CLARITY: THE POWER OF A SAFETY
HUDDLE`. Original attachment preserved at
~/.hermes/webui/attachments/2a31996a5a44/pasted-text-2026-06-23_01-08-06-602.md.
Its shape (this is the format to reuse — see pipeline/scene_brief_template.md):
VIDEO LENGTH 60 seconds
STYLE realistic hospital, L&D + NICU, blurred faces, documentary,
fast opening → calm coordinated ending
SCENE 1 THE SURGE 0-8s
Canva AI Video Prompt → the image/video prompt
Voiceover → the narration line
Staff Dialogue → optional
Text Overlay → the caption that appears on screen
SCENE 2 … SCENE 7
CLOSING CLARITY / COORDINATION / SAFER CARETwo things made it produceable:
1. One prompt + one narration line + one caption per scene. The prompt became a still image,
the narration became the timeline, the caption became the on-screen bar.
2. A 60s spec was allowed to run 122s. The narration, spoken at natural pace, set the real
length; scenes were stretched to fit it rather than trimming the script.
Counts are real tool invocations from the five build sessions (Jun 23 + Jun 27 2026).
| Program | Role | Real usage |
|---|---|---|
Hermes image_generate (FLUX, hosted on fal.ai) | One photographic still per scene | 72 calls |
Hermes text_to_speech (Edge TTS) | The narration; this is what set the 122s timeline | 8 calls |
| MoviePy 2.1.2 + ffmpeg | Compositing and encode: Ken Burns, overlays, grain, vignette, H.264 | 409 terminal runs |
| Google Gemini (your subscription) | 4 stills you generated and supplied | your account |
| Kling AI | The live-motion clip that opens the film | your exports |
| Your phone / other recording | 5 clips mixed into v2 | your uploads |
Scripts written during the build: 51 write_file calls (kept in recovered/original_scripts/).
Not used for the film, only evaluated: Veo 3 (8-second clip limit), InVideo AI, Canva, Runway,
LTX, ElevenLabs, Replicate.
Hard rule that came out of this project: fal.ai is banned for video generation (a Kling clip
rendered through it was unusable — black screen). Stills through Hermes image_generate are fine,
which is exactly what v1 used.
python3 -m pip install moviepy pillow numpy imageio-ffmpeg
# optional, for narration from the shell: pip3 install edge-ttsffmpeg is not on PATH. MoviePy reaches it through imageio-ffmpeg:
import imageio_ffmpeg; imageio_ffmpeg.get_ffmpeg_exe()
# .../imageio_ffmpeg/binaries/ffmpeg-linux-x86_64-v7.0.2For each scene, the brief's prompt goes straight into image generation, landscape aspect:
image_generate(prompt="Cinematic documentary style shot of charge nurse at crowded nurse "
"station in L&D, multiple staff approaching with questions, blurred "
"faces, realistic hospital environment, shallow depth of field",
aspect_ratio="landscape")
# → {"image": "https://v3b.fal.media/files/b/.../x.png"}Then download them into the project:
mkdir -p my-project/scenes
curl -sL -o my-project/scenes/scene1_chaos.png "https://v3b.fal.media/files/b/.../x.png"Prompt formula that worked: `[shot type] of [subject] in [specific hospital area] +
[action/controlled chaos] + blurred faces, no patient identifiers + documentary style,
cinematic lighting, shallow depth of field + realism`. Keeping "blurred faces / no patient
identifiers" in every prompt was deliberate — it is the privacy constraint from the brief.
The narration is the clock. Narration text came from the brief's voiceover lines, concatenated.
text_to_speech(text="<full narration script>")
# → ~/.hermes/audio_cache/tts_20260623_044539.mp3# scriptable equivalent (what pipeline/make_voiceover.py wraps):
python3 -m edge_tts -f script.txt -v en-US-ChristopherNeural \
--write-media my-project/voiceover.mp3
# then read the real duration — build_v2.py used TOTAL = 121.85v2's own copy command, verbatim from the session. Every asset was renamed to a scene name, so
the build script reads like the brief it came from:

]Four acts, matching the brief's emotional arc:
| act | window | colour | meaning |
|---|---|---|---|
| 1 The Gathering Storm | 0–40s | #E84855 | surge, tension, fragmentation |
| 2 Finding the Calm | 40–58s | #4ECDC4 | the safety huddle is called |
| 3 Unifying for the Patient | 58–96s | #45B7D1 | shared awareness, coordination |
| 4 The Core Mission | 96–122s | #F9C74F | calm, clarity, closing |
The exact recipe from build_v2.py:
W, H, FPS = 1280, 720, 24
TOTAL = 121.85
# stills → Ken Burns: full-frame fit, then a slow zoom driven by time t
clip = ImageClip(path, duration=dur).resized((W, H))
clip = clip.resized(lambda t: 1 + zoom * (t / dur)).with_position(("center", "center"))
# your footage → fit height, centre-crop to width (protects against odd aspect ratios)
clip = VideoFileClip(path)
clip = clip.subclipped(start_trim, start_trim + dur) if start_trim else clip
clip = clip.resized(height=H)
if clip.w > W: clip = clip.cropped(x_center=clip.w / 2, width=W)
clip = clip.resized((W, H)).with_duration(dur)
# text: DejaVu Sans from matplotlib for EVERY overlay (no GUI, no font service)
TextClip(text=..., font_size=32, color="white",
stroke_color="black", stroke_width=2, font=FONT_BOLD)
# captions/phase labels sit on a translucent black bar for legibility:
ColorClip(size=(W, 50), color=(0,0,0)).with_opacity(0.45)
# look: static film grain + vignette over the whole film
video = CompositeVideoClip([video, grain, vignette], size=(W, H))
# grain = np.random.randint(0, 10, (H, W, 3)) @ opacity 0.05
# vignette = per-pixel darkened edges @ opacity 0.45
# audio: narration, padded with silence to the full length
if voiceover.duration < TOTAL:
pad = AudioClip(lambda t: 0, duration=TOTAL - voiceover.duration)
audio = CompositeAudioClip([voiceover, pad.with_start(voiceover.duration)])
video = video.with_audio(audio)
video.write_videofile(OUTPUT, fps=FPS, codec="libx264", audio_codec="aac",
preset="veryfast", bitrate="2500k", threads=4, logger=None)Title card = darkened (brightness 0.30) first frame as backdrop + three staggered text lines.
Credits = CLARITY · UNITY · SAFER CARE over the closing scene. Both are just more overlays with
their own with_start/with_duration — there is no separate editing pass.

# v1: cd /workspace/calm-in-the-storm && python3 build_video.pyMoviePy prints progress bar-less output; the June sessions polled the output file while it ran

The gallery and films are served from the VPS, not from a local path:

that; ultrafast is about 5x faster and looks fine for review cuts.
