# Sworn introduction video (larger text for phones)

`artifacts/video.mp4`: H.264 (High, yuv420p), 30 fps, 1920x1080, 59.8 s, with a mono AAC-LC 48 kHz quiet synthesized bed and no voice.
`artifacts/poster.png`: 1920x1080, the frame at 37.5 s (frame 1125, written straight from the PNG sequence).

This is the parent job's video, rendered again from its own `video/render.cjs`. The only changes are the text sizes in scenes 4, 5 and 7, the wrapping those sizes need, and the positions that follow from them. All other frames are bit-identical to the parent script's output: frames 100, 300, 450, 1250, 1400, 1600 and 1720 (scenes 1, 2, 3, 6, 7 before the fee line, 8 and 9) were rendered with both the parent's script and the changed one, and the PNGs compared equal. The audio code was not changed.

```

The RPC calls went to an Ethereum mainnet archive endpoint that forwards to the public endpoint named above. The repository's root `package.json` is an empty file, and Node refuses to resolve modules beneath it (`ERR_INVALID_PACKAGE_CONFIG`). Build configuration may not be edited, so the three scripts were run from an identical copy of `video/` whose sibling `artifacts/` is a symlink to this tree's `artifacts/`. The scripts were not modified for this. Run them the same way, or from any directory without a broken `package.json`.

Font: Liberation Mono Regular is loaded from `/usr/share/fonts/truetype/liberation/LiberationMono-Regular.ttf`, as in the parent's script. That file exists on the render machine, so no font was added to the tree.

## Cards (Ethereum mainnet, block 26248738, hash 0x2a46f7417f73bd4b860c086c72a42a874a8fa6c820b1834ac9ef30b4239711bc)

All seven come from the deployed contracts through `eth_call` and are byte-identical to the parent's. On screen they are only rasterized with resvg and scaled to 680 px. They are never drawn, recoloured, retouched, upscaled by AI or generated. `artifacts/cards/PROVENANCE.json` records the call, arguments and state override for each one. The fetch also writes `card-2.svg` (802cd7fe…6d0e). It is not used in the video.

`artifacts/sworn-mark.svg` (sha256 1f745a9a1e2db3fcdb9d06c7b14f230c49dec80ad6bfdf51f33c81e6e8a6abd6) is the Sworn mark on the end card. **Limitation:** the parent's copy of this file never left its machine and is not in the tree. It was taken byte for byte from the live site's mark, https://swornbyswarm.sites.imd.fun/favicon.svg (a green hexagon on #0a0a0a). It has not been confirmed identical to the parent's file.

## Scenes, times and every line as shown

The card sits at x 110, y 200, 680x680 px, unchanged. Lines type in at 28 characters/s unless noted otherwise. "Fade" lines fade in over 0.4 s. Every line fades out over 0.35 s before its end time. Colours: text #d9e0da, accent #00ff41, muted #8c968e, background #0a0a0a. Position = x,baseline y. Right edge = the computed right end of the line (Liberation Mono advance 0.6 em), and every value is ≤ 1860 (60 px margin inside the 1920 frame).

### What changed against the parent (bold sizes above)

- Scenes 4 and 5: main lines went from 34 to 46 px, and the card labels from 22 to 28 px. Three lines would run past the right margin at 46 px, so they wrap at a word boundary. A break after a full stop is preferred when both halves fit; otherwise the most balanced break is used. Wrapped rows sit 58 px apart, the second row types on right after the first, and the end time does not change. Each line block below moves down by the extra height. Spacing between blocks stays 80 px and the label stays 120 px below the last line, as in the parent. In scene 5 the seat markers keep their place under the "agents" line (52 px below its last row, now y 590 instead of 532), and the oracle lines keep their 84 px clearance below the markers.
- Scene 7: the fee line went from 24 to 34 px. It still fits on one line (right edge 1688), so nothing moved.
- Wording, times, colours, cards, markers, the end card and the audio did not change.

### Frames checked

Rendered frames were inspected at 20 s (frame 600), 27 s (810), 38 s (1140) and 51.5 s (1545). Scene 4: the card is at left with the four text rows and the label to its right, starting at x 870 (the card ends at x 790). The lowest row is the label at y 758, well inside the card's height. Scene 5 (also the poster at 37.5 s): card-3, the five text rows, the eleven filled markers between "7 must agree" and "the oracle signs.", and the label at y 876. Nothing overlaps. Scene 7: four lines with the fee line ending at x 1688. The other scenes match the parent's render bit for bit (see above).

Audio: the parent's own synthesized bed, unchanged. It is a soft A-minor drone (110, 164.81, 220 and 261.63 Hz sines with slow swells) at about −30 dBFS, with 3 s fades. There is no licensed music and no voice. The video can be read with the sound off.

## Limitations

- `sworn-mark.svg` comes from the live site (see above). The parent's own file was not available.
- Because of the empty root `package.json`, the scripts have to be run from a copy of `video/` (see Commands).
- Structural checks (codec, size, duration, card hashes, frame comparison) were done. Visual review covered the frames listed above, not every frame.
