`hero-soma` is the landing backdrop: SoMa, midnight to midnight, 180 frames at
eight minutes each so the loop closes without repeating a minute. It is the only
film shot `chrome: "bare"` — the figures keep the app's panel because its clock
is their caption, but a hero has a headline on top and a second interface under
that is two interfaces arguing. It is also the only one that runs a full 24
hours, because the page seeks it to the reader's local hour and a film starting
at 04:40 has no frame for somebody at two in the morning.
Whole-board was the first camera and was wrong: at that standoff the edge of the
terrain plate stands against the sky across the top of the frame, and midday is
a lot of pale sand.
Encoding is two-stage now — frames to a CRF 18 master, deliverables derived from
it. A time-lapse is near the worst case for inter-frame compression, because the
camera never moves but every pixel changes as the light does, and at the figure
default of CRF 22 this reel came out at 2.5 MB. Deriving from a master turned
'try CRF 28' into ten seconds instead of a twenty-two minute re-shoot, and it
keeps what ships identical to what this script makes rather than something
hand-rolled with ffmpeg the day the size became a problem. It lands at 1440w
CRF 28 (1.0 MB) plus a 960w CRF 30 (402 kB) for small screens, because <video>
has no srcset and a phone has no use for the wide encode.
