Media Use

media-use

The media OS for HyperFrames: resolve · generate · operate · remember — every media type, one skill, zero context noise.

First run: install and sign in to the heygen CLI (the free-usage path), then verify with node <SKILL_DIR>/scripts/resolve.mjs --doctor. Setup and providers: references/setup-providers.md.

Resolve — the one verb

node <SKILL_DIR>/scripts/resolve.mjs --type <type> --intent "<description>" --project <dir>

Returns one line: resolved <id> → <path> (<type>, <metadata>). All search noise stays on disk.

Type	One-line intent
bgm	background music (HeyGen catalog, 10k+ tracks)
sfx	sound effects (bundled 19-file library + catalog)
image	photos, backgrounds (HeyGen asset search, 75k+ vectors)
icon	icons, symbols (transparent)
logo	official brand marks (svgl → simple-icons → GitHub avatar → favicon; never redrawn)
voice	TTS voiceover (HeyGen free-usage path; optional local Kokoro)
grade	measured correction candidate; broad polish/stylization follows Media Treatments
lut	user-provided or explicitly chosen reusable validated .cube file

Before resolving fresh, list reusable candidates with --candidates and judge fit yourself — reuse rules, all flags, ingest (--from), and adopt are in references/resolve.md.

Treat broad visual feedback as media intent

When a user explicitly asks to fix, polish, stylize, obscure, emphasize, or reveal photographic media, read references/media-treatments.md even if they do not name color grading or an effect. Inspect the real <img>/<video>, choose one primary intent, then use deterministic persistence and verification. Use a matching recipe as an optional tested seed, or inspect hyperframes media-treatment --capabilities --json, then request one relevant family/effect with --capability <id> and assemble a custom treatment from canonical controls. Never load --all for ordinary authoring. A treatment may compose correction, a preset, finishing, compatible shader effects, supported keyframes, and optional Registry overlays. Add only source-justified bounded tuning and compatible parts, never effects merely to make the result look more sophisticated. Persist the final combined payload with hyperframes media-treatment.

Use one progressively escalating workflow. For video, inspect one labeled early/middle/late contact sheet rather than reading frames separately. Apply one candidate and inspect one after-sheet for ordinary correction or polish. Escalate to individual frames or moving draft evidence only when the result is ambiguous, temporal, stylized, LUT-based, HDR/LOG-sensitive, private, or brand-critical.

For ordinary correction or polish, persist the final treatment's preset/adjustment JSON. Do not generate a .cube LUT merely to encode exposure, shadows, contrast, or warmth. Use a LUT only when the user supplies one or the selected treatment explicitly owns one. resolve --type grade --for ... --analyze is measurement evidence, not permission to replace the chosen treatment with a generated LUT. Do not recreate supported vignette, grain, blur, pixelate, color, or treatment effects with CSS/SVG overlays; that bypasses Studio controls and the canonical preview/render shader path.

Be proactive — run a media opportunity pass

The human usually can't tell which media would lift the piece. You can. When you build or review a composition, do one grounded scan and then ask once — don't silently add, and don't nag per asset.

Surface an opportunity only when a concrete signal is present:

Signal detected	Offer
On-screen text / a script with no voiceover	TTS voiceover (audio engine)
Emoji or a <div> styled as an icon	resolve real icons
Image that is a placeholder, tiny, or upscaled-looking	a better image (and/or upscale — see references/operations.md)
Hard scene cuts / transitions with no sound	transition sfx
A piece over ~10s with no music bed	bgm
Footage that reads under/over-exposed or color-cast	a corrective grade (inspect it with hyperframes media-treatment --selector '#hero' --analyze --json)
Photographic media that feels visually flat or off-topic	one specific source-appropriate preset or custom treatment, with the intended target named
A meaningful media entrance/reveal that feels static	one supported seek-safe treatment animation; preserve color unless the request also justifies a preset

Rules that keep this a help, not nagware: grounded, not generic (no signal → no suggestion); opinionated + concrete (propose the specific fix with defaults chosen — the human approves all / some / none); once per project (one consolidated ask; respect "leave it"); surface, never silently mutate (color grades especially: propose and preview — a gray-world "correction" ruins an intentional sunset or neon look).
