Lulublox Videos

Turn an idea from the user ("make one about which slide is the fastest") into a vertical Short that is ready to post, animated in Roblox Studio. The star is Lulu, a charismatic and cute R15 girl avatar:

  • Peach skin and long chestnut hair with side-swept bangs, side locks framing the face, and a pink bow.
  • Cartoon face: big oval eyes with violet irises, two highlights and lashes; thin brown eyebrows; blush; a mouth that moves with her voice.
  • Outfit: pink top with puffy short sleeves, a purple pleated skirt that opens with her legs (they never cut through it), and white sneakers with pink soles.
  • Animated with the official Roblox packages (Cartoony, Levitation and R15 emotes).

The audience is kids. Read references/production-rules.md, references/format.md and references/animkit.md before starting.

Everything is in English, always: script, voice, captions, on-screen signs, video title, description, tags and file names. Never produce Portuguese or Spanish lines for this skill. After the voice lines are ready, run scripts/fazer_short.py PROJECT. It runs the audits, records, edits, reviews the captions and renders, and only finishes with the final MP4. --so-conferir only checks the delivery.

This skill depends on the sibling skill roblox-video-editor (renderer, SFX/music library and stickers). The repository's install.py checks for it.

Lulu's voice: Jessica (ElevenLabs, free default voice)

Lulu always speaks with "Jessica - Playful, Bright, Warm", chosen by the user on 2026-10-15. It is a free default (premade) voice in Voices → My Voices, voice ID cgSgspJ2msm6clMCkdW9. Check the ID, not only the name. In each project's roteiro.json: "vozes": {"lulu": "Jessica"}. Do not switch to another voice unless the user asks.

  • Model Eleven v4, language Automatic. Write each line in English with an emotion tag at the start, for example [excited] Hi friends!, [giggles] Oops!, [gasps] No way! or [whispers] Shh.... Do not add an accent tag.
  • The Explore tab copies of these voices may ask for a paid plan. Always use the copy in My Voices and never suggest paying.
  • How to generate and download the lines:
    • With an API key in ELEVENLABS_API_KEY (the user sets it): python scripts/tts_elevenlabs.py roteiro.json --out falas.
    • Without a key: in the user's logged-in browser, type each line, generate it with Ctrl+Enter and keep the eleven_v4 take of the two the site creates. Move the files with scripts/receptor_falas.py PASTA (local server on 127.0.0.1) and postMessage. Then python scripts/alinhar_falas.py roteiro.json falas aligns them with Whisper (English).
    • Never type the user's password or keys.

Originality in every video

Every new video needs an original idea and script in the kids' style of this skill. Before writing, read historico/roteiros.md and the roteiro.json files under entregas/, then compare premise, goal, mechanic, attempts and twist. Changing colors, names or the object of the same challenge does not make an idea new. Save originalidade.json in the project (premissa, objetivo, mecanica, tentativas, reviravolta, projetos_comparados, diferenca_dos_anteriores). After producing, log the script with python scripts/registrar_roteiro.py PROJECT.

How Studio is driven (no MCP, no clicks)

Roblox Studio's command-line task runs a script on the place in edit mode and starts Play: RobloxStudioBeta.exe -task RunScript -localPlaceFile place.rbxlx -runScriptFile script.lua -outputFile out.log -quitAfterExecution.

  • scripts/studio_runscript.py montar --kit --cenario studio/cenario.lua --cena studio/cena.lua --play --saida studio/pipeline.lua installs this skill's AnimKit, builds the set, installs the scene and runs Play.
  • scripts/studio_runscript.py rodar studio/pipeline.lua --place studio/base.rbxlx --gravar viewport.mp4 opens a new Studio window behind the user's windows and records only that window. Never record the whole desktop.
  • The user's own Studio windows are never touched.

Workflow

  1. Project and original idea: create entregas/<topic>-<date>. Copy modelos/base/ (comum.py, edicao.py, cenario_comum.lua) next to the project folders as in a batch: each project has gerar_cena.py, montar_edicao.py, studio/cenario_corpo.lua and roteiro.json.
  2. Script (roteiro.json): English texto for each line, titulo, arquivo (MP4 name), "idiomas": ["en"], vozes, destaques (words in yellow) and a plan per line. Short lines, one idea each, with an emotion tag for ElevenLabs. Format in references/format.md.
  3. Voice: as described above.
  4. Set (studio/cenario_corpo.lua):
    • Colorful and alive, with props around.
    • Mark every floor with K.piso(...).
    • Create Lulu with K.criarGarota("Lulu", K.emPe(pos, lookAt)).
  5. Scene (gerar_cena.py → studio/cena.lua):
    • The timeline comes from the real voice timings, and every line has K.falar from the MP3 envelope.
    • Expressions follow the emotion: happy, smile, surprised, scared, scream, nervous, confident, angry, doubt, dizzy, squint, knockout and wink, her signature.
    • Use dry cuts and K.cortarPara when she changes place.
    • Camera moves end before the next cut (c.ate_corte).
  6. Automatic audit and fixes (mandatory): K.auditar(noob) (collisions) and K.auditarCamera(noob) (face rule) must end with total 0. Her hair, bow and skirt are soft parts (Visual) and are not audited. Then review the frames around every cut, including every 60 fps frame from 0.05 s before to 0.1 s after each cut.
  7. Edit (montar_edicao.py → roblox-video-editor renderer, "entrega": "shorts"):
    • Karaoke captions in English, one idea at a time.
    • A chunk never ends on an article or preposition; "no", "not" and "never" are shown in coral.
    • SFX on every action.
    • Never cut an effect in the middle, and never cut before a zoom ends.
    • Short licensed music at −24 dB under the voice.
  8. Final review: revisar_legendas.py total 0, about −14 LUFS with peaks under −1.5 dBTP, Whisper transcript of the final audio in English, and frame checks.
  9. Delivery (fazer_short.py PROJECT --so-conferir): the final MP4 plus publicacao.txt with an English title, description, hashtags, music credits and voice credit.

Content rules (kids)

  • Original scripts. The user's references are only a format guide.
  • No real Robux promises, links, requests for personal data, scary content, humiliation or bad words. Twists are silly and light.
  • No third-party characters, logos or music.
  • Lulu is kind, curious and funny. She can fail and laugh about it, but she is never mean.
  • Vary sets, jokes and camera angles between videos: AI voices and serial scripts can be flagged as repetitive content.
