The challenge

Make a series that looks like handmade stop-motion without a studio, a crew or a puppet. AI video models are good at single beautiful shots and bad at continuity: characters change colour, gain ears, lose limbs and invent new friends from one clip to the next. The job was to turn that into a reliable production line for children's TV, in two languages.

Five characters, locked on model

Every character has an approved turnaround, a written trait block and a reusable AI element. Every prompt carries the full trait block, because the model drifts without it: Papa Pusti has exactly one ear, Krammi's curved shapes are arms, not ears, and Møssi is orange, never pink.

Family

Møssi · the main character
Krammi · her little brother
Mama Soli · Mum
Papa Pusti · Dad

Friend

Bussi · the friend next door

The pipeline

Møssi turnaround sheet: six views of the orange felt character, front, sides and back, on a cream background.
Turnaround
Møssi seen from the front on a cream background: the single approved view.
Locked view
The root home: a round green door with glowing windows in the roots of a big tree, in a mossy forest.
Locked location
Final shot
  1. Design and lock. I designed the characters in Higgsfield. Their turnaround sheets become reusable Higgsfield elements with a written trait block per character and a fixed set of four locations.

  2. Record first. Every line is recorded in the character's locked voice (ElevenLabs) and transcribed to check it before any animation.

  3. Edit, don't recreate. Each shot starts as an edit of an approved frame, then is animated in Seedance 2.0 with the recorded lines as audio references.

  4. QC every clip. Frame sheets against the trait blocks, word-timed transcripts, silence scans, a colour grade per clip, then assembly.

  5. Music. Original songs made in Suno play over the picture.

What I learned about AI video

The website

downinthemoss.com is a cinematic scroll: you fly from the forest canopy down to the moss, through the root-home door and meet the family one by one. I designed and built it with Claude Code, in English and Spanish, with AI-generated flight segments and separate layouts for desktop and phone. Hosted on Cloudflare Pages.

downinthemoss.com opening screen: the knitted MØSSI title in the moss, under fern leaves.downinthemoss.com, “The root home”: the round door in the roots of a big tree.downinthemoss.com, Krammi's page: Krammi on a green background.

Launch

The theme song is live on YouTube. MØSSI launches in two languages: Down in the Moss (English) and Entre el Musgo (Spanish), each with its own YouTube channel, Instagram and Facebook page.
