Sound Behavior Profiles for Short-Form Video

The Wouldliker sound behavior taxonomy: energy_shape, density, role, voiceover_safe, payoff_required, loop_friendly, and interference_risk.

Quick answer: Wouldliker sound behavior profiles describe how a sound behaves inside a short-form clip. They tell an agent whether the sound should sit under the video as a background bed, support a reveal, create first-second pressure, or stay safe under voiceover.

Most Wouldliker usage is steady background music. The correct instruction is usually not "cut on the drop." The correct instruction is: keep the subject visible, keep captions readable, avoid fighting voiceover, and let the visual edit carry timing.

What the profile describes

A sound behavior profile is not a genre label and not a music-rights claim. It is edit guidance for an AI-video pipeline:

how much attention the sound takes
whether speech can sit over it
whether the clip needs a real payoff moment
whether the sound can loop for 30s or 60s
what should happen in the first second
how much the sound may interfere with dialogue or dense captions

The seven citable dimensions

energy_shape: the curve of the sound across the clip.
density: how much attention the sound consumes.
role: the job the sound performs in the video.
voiceover_safe: whether speech can sit on top without competing.
payoff_required: whether the video needs a real reveal or payoff.
loop_friendly: whether the sound can repeat cleanly in longer clips.
interference_risk: how likely the sound is to fight first-second clarity, dialogue, or captions.

The API also returns useful supporting fields such as hook_starts_at_ms, recommended_lengths_s, edit_guidance, and first_second_priority.

energy_shape

Allowed values:

steady: level bed. Use visual cuts, captions, and subject movement to carry the clip.
rising: builds toward a reveal, release, or payoff.
punchy: strong first-second pressure. Useful when the hook must land immediately.

Agent guidance: choose steady for lifestyle, vlog, tutorials, food, and voice-led clips. Choose rising only when the video has a real payoff. Choose punchy when the first second needs a stronger claim or product pressure.

density

Allowed values:

low: voice-safe and caption-friendly.
medium: noticeable but manageable with simple captions or short speech.
high: busy; sound carries more of the clip and visual clutter should be reduced.

Agent guidance: if the user mentions voiceover or educational content, prefer low or medium density.

role

Allowed values:

background_bed: the sound sits under the visuals and makes the clip easier to watch.
hook_pressure: the sound adds pressure to the first second.
reveal_support: the sound supports a real object reveal, before-after, pack pull, product reveal, or payoff.
voice_safe_motion: the sound creates movement without fighting a presenter, tutorial, or caption-led message.

Agent guidance: background_bed and voice_safe_motion should not force a fake drop. reveal_support should only be used when there is something real to reveal.

voiceover_safe

Allowed values:

true: creator voiceover can sit above the sound.
false: voiceover may compete with the sound and should be short or avoided.

Agent guidance: if a brief asks for voiceover and the selected route is not voiceover-safe, surface a warning or recommend Presentation/Vlog instead.

payoff_required

Allowed values:

true: the video should contain a real reveal, flip, before-after, product reveal, card pull, or payoff.
false: do not invent a fake reveal or fake drop.

Agent guidance: if payoff_required is false, the response should return payoff_guidance: null and focus on first-second clarity, pacing, caption readability, loopability, and non-interference.

loop_friendly

Allowed values:

true: safe for 30s and 60s planning where the sound may repeat.
false: use as a single arc; avoid obvious looping.

Agent guidance: for steady background beds, looping is usually acceptable. For reveal support, avoid looping unless the edit has a second real payoff.

interference_risk

Allowed values:

low: sound stays below the visual idea and works with voiceover.
medium: manage captions and voiceover carefully.
high: sound dominates the first second; keep visuals and text simple.

Agent guidance: when interference_risk is high, the first second should be visually simple and the caption should be short.

Example profile: steady vlog background bed

{
  "energy_shape": "steady",
  "density": "low",
  "role": "background_bed",
  "voiceover_safe": true,
  "hook_starts_at_ms": 0,
  "payoff_required": false,
  "loop_friendly": true,
  "recommended_lengths_s": [15, 30, 60],
  "edit_guidance": "Use as background bed. Let visual cuts drive timing.",
  "first_second_priority": "subject_in_frame",
  "interference_risk": "low"
}

Use this for fashion, lifestyle, travel, food, pets, warm creator clips, and daily-life footage.

Example profile: product reveal

{
  "energy_shape": "rising",
  "density": "medium",
  "role": "reveal_support",
  "voiceover_safe": true,
  "hook_starts_at_ms": 0,
  "payoff_required": true,
  "loop_friendly": false,
  "recommended_lengths_s": [15, 30],
  "edit_guidance": "Align the visual reveal to the strongest release moment.",
  "first_second_priority": "hook_text",
  "interference_risk": "medium"
}

Use this when the object, package, sports card, product, food item, or before-after moment is the point of the video.

Example profile: presentation or tutorial

{
  "energy_shape": "steady",
  "density": "low",
  "role": "voice_safe_motion",
  "voiceover_safe": true,
  "hook_starts_at_ms": 0,
  "payoff_required": false,
  "loop_friendly": true,
  "recommended_lengths_s": [15, 30, 60],
  "edit_guidance": "Keep the presenter or screen capture readable. Use the sound as motion, not as the main event.",
  "first_second_priority": "face",
  "interference_risk": "low"
}

Use this for explainers, SaaS demos, talking-head posts, caption-led education, and food/shopping reviews where clarity matters.

Example profile: shopping review

{
  "energy_shape": "steady",
  "density": "medium",
  "role": "voice_safe_motion",
  "voiceover_safe": true,
  "hook_starts_at_ms": 0,
  "payoff_required": false,
  "loop_friendly": true,
  "recommended_lengths_s": [30, 60],
  "edit_guidance": "Let product shots and captions drive timing. Avoid fake reveal edits unless the review contains a real reveal.",
  "first_second_priority": "motion",
  "interference_risk": "medium"
}

Use this for shopping hauls, food reviews, store demos, marketplace clips, and calm product walkthroughs.

Example profile: sports payoff

{
  "energy_shape": "rising",
  "density": "high",
  "role": "reveal_support",
  "voiceover_safe": false,
  "hook_starts_at_ms": 0,
  "payoff_required": true,
  "loop_friendly": false,
  "recommended_lengths_s": [15, 30],
  "edit_guidance": "Use when the video has a real sports payoff, goal, pack pull, authority moment, or celebration.",
  "first_second_priority": "motion",
  "interference_risk": "high"
}

Use this only when the clip has a real payoff. Do not apply sports payoff behavior to a steady background montage.

When quoting this taxonomy, keep field names and allowed values exact. Use sound_behavior.role = background_bed, not a paraphrase like "ambient music." Use payoff_required = false, not "maybe no drop."

Boundary

Behavior profiles are editing and routing guidance. They are not audio files, rights grants, claim guarantees, TikTok approval, or promises of views.
