Deep Scene-Level Content Understanding

Fingerprint+ transforms video into structured, machine-readable intelligence.

By analyzing visual signals, dialogue, audio cues, and narrative context across every scene, the API generates semantic fingerprints and rich metadata that describe the content beyond traditional editorial tagging.

This includes content embeddings, mood signals, genres, keywords, language detection, and automatically generated multilingual synopses.
Features
Content Fingerprint Embeddings Vector representations capturing the semantic structure of a title for similarity search and recommendation
Mood & Emotion Signals Quantified mood indicators and descriptive mood tags derived from scene dynamics
Genres & Keywords Automatically extracted thematic and narrative descriptors
Language Detection Identification of the primary spoken language
AI-Generated Synopses Short and long summaries generated automatically in multiple languages
Smart Lists

Transform Titles into Connected Experiences

Similarity intelligence converts isolated titles into dynamic networks of related content.

Instead of static “related items,” platforms gain adaptive, behavior-driven content relationships.

Automated Understanding of Information-Heavy Content

Content summaries provide concise, structured insights for complex or information-dense assets.
Features
Summary Concise, AI-generated description capturing the narrative essence of the asset
Keywords Semantic signals designed to enhance discovery, search, and navigation
Structured Sections Enhanced accessibility and navigation
Ad-Breaks
Binge Markers

Understand Emotional Dynamics 
Across Content

Emotion intelligence reveals how content evolves across time, scenes, and narrative structures.
Features
Temporal Emotion Mapping Continuous emotional signals across the full content timeline
Emotion Probability Signals Probabilistic detection per segment with intensity scoring
Structured Emotional DimensionsQuantitative modeling via valence, arousal, and dominance
Scene-Level PrecisionEmotion intelligence aligned with temporal boundaries for playback workflows
Thumbnails

Dynamic Thumbnail Generation

Thumbnails are among the most powerful decision triggers in streaming interfaces.

The JIT Thumbnails API enables platforms to generate thumbnails dynamically based on scene-level AI analysis rather than relying on static artwork or manual frame selection.

Thumbnails can be tailored to reflect specific moments, characters, moods, and visual presentation requirements.
Features
Scene-Aware Frame Selection Thumbnails from visually and narratively relevant moments
Character-Driven Visuals Emphasize specific characters or interactions
Composition & Framing ControlAdapts to layout needs including positioning and close-ups
Visual Quality OptimizationFrames evaluated for clarity, brightness, and stability
Safety & Suitability ConstraintsRespects brand and content-safety requirements
Vertical & Cross-Platform FormatsOptimized for horizontal, vertical, and mobile-first
Integrated Branding SupportOptional logo insertion for consistent brand presentation
Clips

Dynamic Clip Generation & Intelligence

Short-form video assets have become a core driver of discovery, engagement, and monetization across modern streaming and mobile-first environments.

The JIT Clips API transforms clip creation from a manual editorial task into an intelligent, AI-driven system.

Instead of manually browsing timelines and cutting scenes, platforms can dynamically generate clips aligned with narrative structure, emotional tone, character presence, visual quality, and content suitability requirements.

Clips evolve from simple excerpts into decision-ready assets enriched with contextual intelligence.
Content-Aware Selection Clips from narratively and visually relevant moments
Semantic Clip Discovery Free-form search to find clips by mood, theme, or situation
Narrative Boundary AlignmentRespects scene transitions and speech dynamics
Character-Driven SelectionEmphasize specific characters or interactions
Editorial & Brand ControlAligns with safety policies and creative constraints
Vertical & Cross-Platform FormatsAdapts to horizontal, vertical, and mobile-first
Balanced Clip DistributionConsistent representation across the content timelinene
Precision Clip Boundaries Clips are delivered with exact temporal and frame-level definitions
Relevance & Ranking Signals Each clip includes contextual scoring for prioritization and optimization
Semantic & Discovery ContextGenerated assets retain the logic behind clip selection
Character & Scene IntelligenceStructured signals describing visible entities and scene composition
Safety & Suitability SignalsAutomated classification indicators supporting brand-safe (profanity / nudity) workflows
Emotional DynamicsClips enriched with viewer-relevant emotional dimensions
Structured Metadata DescriptorsMood, themes, environments, and keywords embedded within each asset
Multi-Asset DeliveryProduction-ready clips accompanied by associated preview imagery
Intro, Recap & Credit Detection

Playback Structural Intelligence

Viewer experience is shaped not only by content, but by how seamlessly playback adapts to narrative structure.

The Markers API automatically detects structural content segments such as intros, recaps, previews, and end credits with high temporal precision.

Instead of relying on manual tagging or editorial workflows, platforms gain a scalable intelligence layer that enables frictionless playback experiences and binge-optimized viewing flows.
Features
Automated Structural Detection Identifies intros, recaps, previews, and credits automatically
Precise Segment Boundaries Accurate start/end positions for playback control
Playback-Ready MarkersImmediate integration into skip and navigation workflows
Version-Aware ConsistencyPredictable results across catalog updates
Catalog-Scale AutomationStructural intelligence across entire libraries
Ad-Breaks
Contextual Advertising

Narrative & Context-Aware Monetization

Advertising effectiveness is shaped not only by placement, but by contextual relevance and viewer perception.

The Contextual Ad-Break API identifies advertising opportunities by combining scene-level structure, emotional dynamics, semantic understanding, and content suitability signals.

Instead of treating ad breaks as purely temporal events, placements become narrative-aware and context-driven.
Features
Narrative-Aware Placement Aligns with storytelling rhythm and scene dynamics
Semantic Context Intelligence Each candidate enriched with scene themes and environments
Mood & Emotional SignalsPlacements reflect emotional tone and narrative intensity
Confidence-Ranked OpportunitiesMulti-model agreement prioritization
Brand & Safety AwarenessContent suitability for advertiser-safe workflows
IAB Taxonomy AlignmentStructured classification for content-aware advertising
Frame-Level PrecisionHigh temporal and frame accuracy for seamless integration

Automated Detection of Sensitive Content

The Content Safety API automatically detects sensitive or potentially inappropriate content in video assets.

By analyzing dialogue, audio signals, and visual frames, the API identifies profanity in speech and nudity in visuals, enabling platforms to enforce editorial guidelines, parental controls, and brand safety policies at scale.

The API returns precise timestamps and confidence scores, allowing systems to automatically flag, filter, or restrict content segments.
Features
Profanity Detection
Identification of profanity within spoken dialogue
Timestamped segments where profanity occurs
Severity scores indicating the intensity of language
Asset-level classification labels
Nudity Detection
Frame-level detection of nudity in visual content
Timestamped frame positions
Confidence scores for detected visual signals
Safe / unsafe classification labels
