v0.4.0: genre templates, editable projects, delivery and accessibility

motion-pack v0.4.0: 24 genre templates, one editable project file, delivery and accessibility.

The catalog grows from 954 to 1132 components. Genre templates go from 7 to 24, plus 12 part demos. Every number in this section comes from tools/count.py or from a test or check named next to it.

New: eight lanes of work

• SaaS: three templates (saas-launch, saas-feature-drop, saas-explainer), each with a 16:9 cut and a 9:16 re-layout. They come with 13 SaaS kit parts (an app window, a cursor journey, a command bar, an AI answer, pricing cards and more) and 12 synthesised UI sounds in a new saas_ui bundle. The demo screens show a fictional product with labelled placeholder data.
• Hardware: three templates (hardware-reveal, hardware-teaser, spec-sheet). They add 14 three.js hardware objects, an exploded-view choreographer, the hw.* overlay parts, 15 hardware sounds plus a hardware_launch bundle, and Blender recipes that take your own GLB.
• Film: three templates (trailer, title-sequence, short-film). They add 28 trailer sounds and a trailer bundle, genre trailer scores (thriller, sci-fi, horror, drama), a trailer cut planner, 8 film looks with LUTs, and 15 film overlay parts.
• Human: five templates for footage you record yourself (tutorial, vlog-personal, podcast-clip, founder-story, course-lesson), with 15 overlay parts. No person, voice or recording is ever generated. A missing input renders as a labelled placeholder, and a pull quote must be a verbatim run of the transcript or the build stops.
• Research and structure: patterns/ holds 20 beat sheets (section timing as a share of runtime, average shot length, text ceilings, the CTA window) and 13 hook archetypes with frame-0 rules. tools/structure_check.py scores a plan against them (26 tests, 15 mutants). The sourced, graded evidence is in docs/research/.
• Editable projects and the mp CLI: one project file (templates/_shared/project.schema.json) sets brand, text, media, voice, music, length, platforms and aspects for every genre template. tools/mp does list, new, set, build, render, check, brand and doctor. docs/EDIT-WITHOUT-CODE.md walks a non-coder through it.
• Delivery and accessibility: captions (SRT, WebVTT, IMSC1.1 TTML or burned in, with SDH), audio-description scripts, an accessibility lint (tools/a11y_check.py: flashes, caption contrast, size, reading time, colour-blind safety), 14 platform delivery presets (tools/deliver.py) and a Lottie export of kinetic type and draw-on icons. Guide: docs/DELIVERY-AND-ACCESSIBILITY.md.
• Explainer and data: three templates (explainer-diagram, data-story, process-howto). They add 11 diagram, chart, map and process parts, a number formatter (international, Indian lakh / crore, European, SI), a deterministic graph layout, and data honesty gates: a dataset with no source, a chart with no unit or a bar chart that does not start at zero stops the build. The gates check the form of the evidence, not its truth.

New parts from the reference rounds (r78 and round 8)

• ui.glassPanel, ui.rimLight, ui.reviewLayer, ui.approvalSlider, type.sentenceAcrossShots, layout.textWall, layout.pillWall, device.lockScreen and background.skyClouds. The same round adds an ab-replay before / after audio-swap story shape, an ears/ab_replay check, and the demo-r78 part demo.
• caption.soundOnPill, a frosted "Sound on" pill for muted autoplay, and ui.stateChip, a persistent corner chip that flips on planned frames. Each comes with its sound cues (68 checks in type/tests/chips.test.mjs).

Fixed: every aspect renders at its own size

• In the 16-17 Oct test renders, four templates wrote a 1920x1080 file named -9x16, and vlog-personal wrote a 1080x1920 file named -16x9. Every genre template now builds the aspect mp asks for, whether through a project file or --aspect. tools/tests/aspect-builds.test.mjs runs 100 checks over every template and aspect.
• The wrong-size guard: mp render now ffprobes every file. A file whose size does not match its aspect fails, and is kept as .WRONG-SIZE.mp4. mp check runs the same test on every file in renders/.

Best demos

Three renders from the 19 Oct run pass loudness and frame size and read well on their contact sheets. They are attached to the v0.4.0 release (not committed):

• ad-9x16.mp4 (1080x1920, 15 s): the ad template driven by examples/project.example.json. Eyes and ears report no fails.
• character-spot-16x9.mp4 (1920x1080, 16 s): the wordless character-spot. Eyes and ears report no fails.
• short-film-16x9.mp4 (1920x1080, 53.6 s): short-film, with the film-scene three.js plate in its stage slot. It passes loudness and ears; eyes flag black frames, banding and readability on its dark placeholder plates.

Known weak spots (read before you rely on a template)

On 19 Oct every genre template was rendered through mp render at both aspects, 44 files in all, and checked with mp check (eyes, ears, loudness and frame size). The renders use the templates' own placeholder plates. Every file is the right size. 38 of the 44 pass loudness (-14 LUFS ± 0.5, true peak ≤ -1 dBTP).

• Quiet renders, not fixed in this release. data-story comes out at -21.46 LUFS, explainer-diagram at -22.75 and film-scene at -17.55, at both aspects.
  • In data-story and explainer-diagram the mix WAV is at -14.0 LUFS. The HyperFrames render then lowers the whole track by 7.3 and 8.6 dB, because its true-peak guard reads the encoded audio as over -1 dBTP (its log says "Audio lowered by ... dB").
  • The film-scene mix itself stops at -17.49 LUFS, because the mixer reaches its -2.0 dBTP ceiling first and has no limiter.
  • Neither is a gain or target setting, so this release leaves them alone. A workaround: limit the master at 4x oversampling, keep the rendered picture and remux the audio yourself, then measure the MP4 with ffmpeg -af ebur128, not the WAV.
• ears: founder-story fails the sync check at both aspects. Its caption row also overlaps the "Founder name" lower third and the speaker tag. film-scene fails ears sync as well as loudness.
• eyes, banding: nearly every dark template fails the banding check. Add grain or lower the CRF.
• eyes, frame 0: hardware-teaser, saas-feature-drop 16:9, title-sequence, hardware-reveal, process-howto, data-story and explainer-diagram.
• Label collisions seen on the sheets:
  • spec-sheet 9:16: the "AI COMPUTE" label sits under "120 TOPS" at 19.2 s.
  • hardware-reveal: "Machined from one block" sits over the watermark at 9.2 s, and the port labels overlap at 34.8 s.
  • character-spot 9:16: the end title touches the left edge at 15.4 s.
  • data-story: the footer repeats its demo-data line at 60 s.
• eyes, readability and safe zones: saas-feature-drop headlines sit at 76-92 px, under the 96 px floor for wide frames. Placeholder tags, captions or titles sit outside the safe area in 20 of the 44 renders, among them vlog-personal, tutorial, founder-story, the trailers and the 16:9 ad.
• Structure scores: hardware-reveal scores 72, because its 6-8 s shots run long against the 1.5-3.5 s pattern. short-film reads 0 on pace, because its placeholder plates have no motion events. title-sequence at length=60 holds after 34 s with the 10 demo names.
• Not heard by a person: the new sounds were measured by sfx/qa.py and music/qa.py (0 fails), not auditioned.

On main after the v0.4.0 tag

• MP3 previews for the 55 new sounds and 4 genre trailer beds, and the catalog now points at them. Without them the Pages build of the catalog failed, because the WAV masters are not in git.
• This changelog section: the 19 Oct render results, the best demos and the weak spots above.
