The paid stages are separate capabilities:</p>\n<ul>\n<li><strong>the styled hero</strong> (identity lock) — <code>create-image-fal</code> (nano-banana edit) restyles the\nbrand's REAL product photo onto the seamless brand-color studio set. This is the seed for\nBeats 1 &amp; 2 and the fallback end-card background. The product geometry is the real product,\nnever AI-invented.</li>\n<li><strong>Beats 1 &amp; 2</strong> (hero rotation + macro push-in) — <code>create-video-fal</code> image-to-video seeded on\nthat styled hero.</li>\n<li><strong>Beat 3</strong> (physics reveal) — <code>create-video-fal</code> Veo3 i2v seeded on Beat 1's last frame.</li>\n<li><strong>the bed</strong> — <code>create-music-elevenlabs</code> (<code>force_instrumental</code> true).</li>\n</ul>\n<p>There is <strong>no Higgsfield / Marketing Studio</strong> in this format; every paid call routes through the\nfal-proxy / elevenlabs-proxy so it bills the Ads agent. This capability spends nothing: given the\nfour delivered beats + the brand wordmark it stitches the finished master. Re-cuts (a swapped end\ncard, a re-timed beat, a re-mixed bed) reuse the existing beats and cost <strong>$0</strong>.</p>\n<p><code>config.example.json</code> is the worked example (DIBS Beauty \"Desert Island Duo\", ~15s 720×1280).\n<code>build_endcard.py</code> and <code>build_masters.py</code> are the runnable free assembly (below). <code>PIPELINE.md</code>\nmaps every config block to its source step.</p>\n<h2>1. Beat 1 last-frame extract — the shared anchor</h2>\n<p>Extract Beat 1's last frame once (<code>ffmpeg -sseof -0.1 -i beat1.mp4 -frames:v 1 beat1_last_frame.png</code>). It is the shared anchor: it seeds the Veo3 Beat 3 (paid, upstream) AND\nbacks the Beat 4 end-card hyperframe. Extracting it once keeps the product + lighting identical\nacross the reveal and the close, so the geometry never AI-drifts.</p>\n<h2>2. End card — <code>build_endcard.py</code> (Playwright hyperframe, no AI text)</h2>\n<pre><code>build_endcard.py --bg beat1_last_frame.png --headline \"YOUR SANCTUARY AT HOME\" \\\n    --wordmark brand-logo.svg --out endcard.png [--headline-size 86] [--headline-color auto]\n</code></pre>\n<p>Beat 1's stilled last frame + a scrim + a Playfair headline + the brand's <strong>REAL</strong> wordmark\n(SVG inlined and recolored, or a PNG). It renders at 1080×1920 via <code>scripts/shoot.js</code> (Playwright)\nthen ffmpeg-scales to 720×1280 (matching the viewport to the output dims clips the right edge).\nThe brand text is <strong>never</strong> AI-rendered — a diffusion model garbles a wordmark. <code>--headline-color auto</code> picks warm-white on a dark/saturated bg and dark ink on a light/pastel bg. Playfair loads\nfrom Google Fonts (bundle the .ttf for offline determinism). If the resolvable Playwright wants an\nuninstalled browser build, <code>export PW_CHROME=&lt;installed Chromium binary&gt;</code>.</p>\n<h2>3. Assemble + mix — <code>build_masters.py</code> (per-beat normalize + hard-concat + music)</h2>\n<pre><code>build_masters.py --config config.json --clips working/clips --endcard endcard.png \\\n    --music working/music.mp3 --out working/master.mp4\n</code></pre>\n<p>Reads the config, then for each beat: <strong>trims to its window</strong> (<code>beats[].duration_sec</code>, with\n<code>beats[].trim_start</code> — defaults to 1.0s for the Veo3 reveal so its 8s take lands on rise → peak →\nearly settle), normalizes to the brand canvas (strip the i2v model's auto-audio with <code>-an</code>, scale</p>\n<ul>\n<li>pad to 720×1280 with the brand <code>bg</code> pad color, 24fps, yuv420p, crf 18), and — for the end card —\nholds the still for its duration. The normalized segments are hard-concatenated (concat demuxer)\nin beat order — no dissolves. <code>reveal_variant == rotation_only</code> skips Beat 3 automatically.</li>\n</ul>\n<p>Then it mixes one ElevenLabs instrumental bed under the concat: <code>afade</code> in 0.3s / out 0.6s +\n<code>loudnorm I=-16 TP=-1.5 LRA=11</code>, <code>apad</code> + atrimmed to the master duration. Music-only — no VO, no\nsecond bed. Output is a 720×1280 h264 + aac master (~15s). Deterministic, no paid calls, no keys.</p>\n","files":[{"path":"scripts/build_endcard.py","sizeBytes":5663,"isText":true},{"path":"scripts/build_masters.py","sizeBytes":4875,"isText":true},{"path":"scripts/config.example.json","sizeBytes":10335,"isText":true},{"path":"scripts/PIPELINE.md","sizeBytes":5073,"isText":true},{"path":"scripts/README.md","sizeBytes":3836,"isText":true},{"path":"scripts/shoot.js","sizeBytes":1189,"isText":true},{"path":"SKILL.md","sizeBytes":4276,"isText":true},{"path":"skill.meta.json","sizeBytes":329,"isText":true},{"path":"tests/smoke-test.md","sizeBytes":1112,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
