Higgsfield Repurpose — Shorts, Clips, and Analysis of Finished Video
QUICK FACTS
Routing aids — read the linked sections for the full rules. Nothing in this sub-skill is field-tested.
- Four surfaces take a video that already exists: Shorts Studio (restyle → shorts), Clipify (YouTube → subtitled clips), Virality Predictor (a score), Video Analysis (a scene breakdown) →
- Paid vs free is per tool —
shorts_studio_create is PAID; its get_cost estimate and preset creation state they are free; list / status calls state no cost →
- Shorts Studio: source 4–120s, output 720p only, 9:16 default (16:9 optional); preflight with
get_cost: true + duration_seconds — no preset or upload needed for the estimate →
- Shorts Studio presets store a STYLE (≤10 media, videos ≤30s, public https URLs) — write the preset prompt as laws, not adjectives →
- Clipify: exactly ONE YouTube URL per job; 1–20 clips; 9:16 / 1:1 / 16:9; subtitle font, case, position and highlight colour are parameters →
- Virality Predictor: input is a confirmed uploaded video or a completed generated video; it is a PREDICTION — compare variants with it, don't treat it as audience data →
- Video Analysis: exactly one of uploaded video / YouTube URL; ~3–5 min; warn up front: the longer the video, the less accurate the breakdown →
- Burned-in captions, cuts, soundtrack, voice swaps are other surfaces — hand-off map →
What this sub-skill is for
Every surface here starts from a video that already exists — a finished ad, a long
YouTube video, a generated clip — and produces something derived from it: restyled
shorts, cut-down clips, a performance prediction, or a scene list. None of them writes a
generation prompt from scratch; that is the rest of this library.
| Surface | Input | Output | Tool / model |
|---|
| Shorts Studio | One uploaded video, 4–120s + a style preset | A set of AI-restyled short-form clips | shorts_studio_* (MCP) |
| Clipify | One YouTube URL | Ready-to-share clips with subtitles | clipify (video catalog model) |
| Virality Predictor | An uploaded or generated video | Virality / engagement / attention / hook / retention-risk prediction + dashboard | virality_predictor (MCP) |
| Video Analysis | An uploaded video or a YouTube URL | Scene-by-scene analysis | video_analysis_* (MCP) |
Not this sub-skill: changing what is inside a clip (swap an object, re-light, extend
it) — that is ../higgsfield-seedance-2-5/SKILL.md (video_edit / video_extension),
../higgsfield-seedance-vfx/SKILL.md, or Genjutsu (../higgsfield-marketing-studio/SKILL.md
§ 14). Many edited versions of one ad → Ad Multiplier, same § 14.
Paid or free — read this before calling anything
[OFFICIAL — Higgsfield MCP tool schema, 2026-09-26] unless marked.
| Tool | Spends credits? | Evidence |
|---|
shorts_studio_create | PAID — "reserves credits" | Tool description |
shorts_studio_create with get_cost: true + duration_seconds | Free — "estimate the credit cost without submitting a job"; no preset or source video needed | Tool description |
shorts_studio_create_preset | Free — "just stores a STYLE — no generation, no credits" | Tool description |
shorts_studio_list_presets · shorts_studio_list_sessions · shorts_studio_status | Not stated — list / status calls that submit nothing; not called free here | Tool descriptions (silent on cost) |
clipify | Not stated. It is a video-catalog model, so it runs through generate_video / the CLI and can be preflighted with get_cost: true (MCP) or higgsfield generate cost clipify … (CLI — confirm the flag form with higgsfield model get clipify first) | [OFFICIAL — platform, 2026-09-26] snapshot has no price field |
virality_predictor | Not stated, and the tool has no get_cost field | Tool schema |
video_analysis_create | Not stated, and the tool has no get_cost field | Tool schema |
video_analysis_status · video_analysis_jobs | Not stated — status / list calls that submit nothing; not called free here | Tool descriptions (silent on cost) |
Where the schema is silent, do not call it free. Check the balance before and after
(balance / transactions on MCP, higgsfield account status on the CLI) the first time
a surface is used, and record what it actually cost. No prices appear in this file because
none were measured.
Shorts Studio
[OFFICIAL — Higgsfield MCP tool schema, shorts_studio_*, 2026-09-26]
"Start a Shorts Studio short: restyle one uploaded source video (4s–120s) into a set of
AI-generated short-form clips using a style preset. PAID — reserves credits."
| Param | Values | Notes |
|---|
source_video_id | uuid | The uploaded video's video_input id (media_upload_widget, type=video). Required unless get_cost |
preset_id | uuid | From shorts_studio_list_presets or shorts_studio_create_preset. Required unless get_cost |
preset_source | user · cms | The preset item's own preset_source. Required unless get_cost |
aspect_ratio | 9:16 (default) · 16:9 | Output orientation |
resolution | 720p | The only value — the schema pins it as a constant |
get_cost | bool | With duration_seconds, returns the estimate and submits nothing |
duration_seconds | > 0, ≤ 120 | Source length; required when get_cost is true |
The run, in order:
- Estimate first —
get_cost: true + duration_seconds (free; no preset, no upload).
- Pick or make a style —
shorts_studio_list_presets returns the user's own presets
first, then the CMS library (paginated via next_cursor); or make one (below).
- Upload the source — the user uploads through
media_upload_widget (type=video);
the tool asks for an upload before it is called, never a chat attachment.
- Create — PAID. Returns a session with empty
job_ids.
- Poll
shorts_studio_status until clips appear. status='completed' means every
clip job is terminal, not necessarily successful — check each clip.
Schema mismatch to know about: shorts_studio_status says to poll each clip's
job_id "via job_status", but no job_status tool is in the connector's 2026-09-26 tool
list — the listed job tools are jobs_wait, job_display and show_generation_by_ids.
Which one the status tool means is unverified.
Not published: how many clips a session produces, how long each is, and what the
restyle keeps from the source (timing, audio, framing). Look at one real session before
promising any of them.
Style presets (free)
shorts_studio_create_preset stores a style from reference media — no generation, no
credits.
- Limits: ≤ 10 media total; each video ≤ 30s (send
duration so the cap applies);
every media item a public https URL (use an uploaded media's URL, or
media_import_url first).
- Fields:
name (required), prompt (optional style direction), image_medias,
video_medias, thumbnail.
- Naming: Higgsfield's own tool instruction is to give an unnamed preset a random
friendly two-word name rather than ask — follow it.
- What this library adds
[INFERENCE — untested]: a style preset is a saved style
block, the same job as Cinema Studio's Manual Style — so write its prompt the same
way: laws, not descriptions (grade behaviour, lighting law, texture, camera register),
no vague labels, no director name-drops. See ../higgsfield-cinema/SKILL.md § Manual
Style — Authoring Guide.
Clipify
[OFFICIAL — platform, 2026-09-26] — model clipify, "Turn one YouTube video into
ready-to-share clips with subtitles" (video catalog, ../../specs/models_explore_snapshot_2026-09-26.json).
| Param | Values | Default |

segment_seconds | 2–60 — "Segment duration in seconds" | 10 |
Clipify vs Shorts Studio. Clipify cuts one YouTube video into subtitled clips; it
has no style or restyle parameter. Shorts Studio restyles one uploaded video into
AI-generated clips from a preset. Long talk / podcast / tutorial → clips: Clipify. A
short piece whose look should change: Shorts Studio.
The source is fetched from YouTube — clip only videos the user owns or has the rights to.
What segment_seconds controls beyond its one-line description is not documented.
Virality Predictor
[OFFICIAL — Higgsfield MCP tool schema, virality_predictor, 2026-09-26]
"predicts a video's virality potential, engagement, attention, audience response,
retention risk, hook strength, and creative performance with an interactive dashboard."
action: "create" with params.medias: [{role: "video", id: <uuid>}] — the id is a
confirmed uploaded video media_id or a completed generated video job_id;
params.model is the constant "virality_predictor".action: "preview" with params.job_id re-opens an existing dashboard.- CLI face: Higgsfield's own skills repo says its Virality Predictor path "Uses
Virality Predictor (
brain_activity) with --video" [OFFICIAL — Higgsfield skills repo README, v0.12.0]; CLI 1.1.23 model get brain_activity shows a text-output model named
"Brain Activity" that requires medias. That the two are the same product rests on that
README line — not verified here.
How this library uses it [INFERENCE — untested]:
- It is a prediction, not audience data. This repo has never compared its scores with
real performance. Report it as "the predictor says", never as "this will go viral".
- Compare variants, don't chase a number. The useful question is relative: hook A vs
hook B on the same ad, cut 1 vs cut 2. Rewriting a creative only to move one score is
optimizing the instrument.
- Natural pairings: hook variants from
../higgsfield-marketing-studio/SKILL.md, Ad
Multiplier versions (same skill, § 14), campaign batches in
../higgsfield-content-factory/SKILL.md.
Video Analysis
[OFFICIAL — Higgsfield MCP tool schema, video_analysis_*, 2026-09-26]
- Input — exactly one of:
video_input_id (an uploaded video's media id) or
youtube_url (https on youtube.com, www.youtube.com, m.youtube.com or youtu.be
only).
- Queued: returns
status='queued'; poll video_analysis_status every 30–60 seconds
until completed (scenes populated) or failed (fail_reason populated). "Processing
typically takes 3-5 minutes on average." Past jobs: video_analysis_jobs.
- The warning the tool requires, verbatim: "warn the user up front that the longer
the video, the less accurate the scene-by-scene analysis becomes — short clips give the
most reliable results." Say it before submitting, every time.
- Practical consequence: trim to the sequence you actually care about before uploading.
Uses in this repo [HYPOTHESIS — UNMEASURED]:
- Reference breakdown — a short reference sequence → a scene list to seed
../higgsfield-shotlist-director/SKILL.md or to audit with
../higgsfield-scene-engine/SKILL.md. Analyze a reference for its structure; the
shotlist still gets written, not copied.
- Cut check — did a generated multi-shot clip actually cut where the prompt declared
("strictly N shots")? The analysis is a second pair of eyes, not a verdict.
- The output's shape beyond "scenes" is not documented. Treat what comes back as notes to
verify against the video, never as ground truth.
