The operator recorded the six scenes and ruled on their length: use them whole,
"they had been cut as I liked them". Jellyfin, Tandoor, OnlyOffice, Immich,
RomM, Paperless, 0.6s crossfades, 36.6s looping at 904x556.
- hero-clip.mp4 (1 134 KB) + hero-clip.webm (1 295 KB) + hero-poster.webp
(53 KB), one set for both languages: the recordings are the same on / and /en/.
- The hero <video> sits in the frame's cut-out hole at z-index 1, the frame above
it at 2. No autoplay attribute: the page's script starts it when the hero is on
screen, pauses it when it leaves, and never starts it under
prefers-reduced-motion. With JS off the poster stays.
- make_hero_clip.py reads each scene's own length (ffprobe) instead of cutting
every one to a fixed window, and the xfade offsets count from the running sum
minus one fade per transition already made.
- site.css ?v=26 on all 22 pages.
NOT verified: playback in this workstation's Chrome, whose media pipeline loads
nothing at all today (a 1 KB generated WAV blob stalls the same way, with no
error) - which rules the clip out as the cause. Geometry, layering and the
poster frame were verified in the browser.
Jellyfin, Paperless and RomM were filmed on those projects' own public demo
sites; the films in the Jellyfin scene are public-domain prints.
The operator asked for the laptop's screen to show a few seconds of real apps
running. His decision: he records the raw clips, the assembly is built here. So no
Playwright and no new dependency - ffmpeg 7.1.5 is already on DooPlex.
NOT ON THE PAGE YET. The live hero still shows the still picture; this commit is the
two finished pieces plus the measurements behind the format choice.
scripts/make_hero_clip.py
NN-appname.ext in -> scaled and centre-cropped to the screen's 1.626:1, crossfaded,
out as mp4 (h264) + webm (VP9) + a webp poster. Runs on DooPlex; Windows has no
ffmpeg. Not part of any build, gate or deploy: the site has no build step, so the
output is committed like any other picture. Proven end to end against six
placeholder scenes built from the repo's own app screenshots (21s loop -> mp4
480 KB, webm 609 KB, poster 83 KB).
WHY NOT A GIF - measured, six crossfaded scenes:
904x556 mp4 331 KB | webm 411 KB | GIF 2676 KB for HALF the length
1130x696 mp4 775 KB | webm 1196 KB | webp 2551 KB
A GIF is ~11x the mp4 for the same seconds and dithers to 256 colours on a dark UI.

The laptop render with its SCREEN CUT OUT to transparency, so a clip plays under the
bezel with the glass reflection over it. The reflection is PAINTED: lifting the
bright pixels out of the AI-drawn screen dragged a ghost of the drawn UI along.
Hole: left 11.041% top 12.345% width 79.817% height 64.305%, ratio 1.626:1. Two
pixels of slack - a tight rect showed the drawn sidebar's highlight, a loose one
showed page background at the top left; both were seen in the browser.
The page will load it as <video muted loop playsinline preload="none"> with the first
frame as poster, started only on scroll-into-view and never under
prefers-reduced-motion. First paint: frame 59 KB + poster ~80 KB against today's single
57 KB still; the ~330 KB clip comes after, or never if the visitor does not scroll
there. No "loading" graphic needed - the poster IS the loading state.
The recording brief is in E:\felhom-video\README.txt (outside the repo: the raw files
are large and the repo is public).
