In streaming and studio packaging, an Adaptation Deck translates literary characters into actionable casting requirements, visual screen archetypes, and demonstrable scene chemistry. Rather than relying on simple text summaries, producers use these one-sheets to pitch buyers (Netflix, Prime Video, Hulu) on why two specific leads will ignite on camera.
Use this workspace to test different lead combinations, align tone tropes with platform programming priorities, and generate pitch-ready cards for author reps, showrunners, and casting directors.
Every card exports at full 1200×675 high-res PNG with proper typography, studio watermarks, character motivation beats, and platform badges ready for keynote pitch decks.
In the casting studio, screen chemistry is evaluated across four core dynamics: dialogue friction, emotional trust, physical synchronization, and dramatic stakes. In the Icebreaker preset, friction is eighty-eight, trust is ninety-two, physicality is ninety-five, and stakes are eighty-four percent, summing to a composite score of ninety-one point two. Because both friction and trust exceed eighty-five, the engine assigns the tension dynamic Friction and Care, signaling a golden rivals-to-lovers story arc. Adjusting any slider instantly recalculates the telemetry bar and re-renders the high-resolution production deck on canvas, ready for studio export.
How does this casting studio convert character profiles and slider dynamics into a composite chemistry score and pitch deck?
This adaptation casting deck studio pairs literary characters with cast attachments and evaluates four dynamics: banter friction, emotional trust, physical sync, and narrative stakes. The JavaScript engine computes a composite Chemistry Index using fixed linear weights (25% friction, 30% trust, 30% physical synchronization, and 15% stakes) and assigns tension labels based on threshold rules. The resulting metrics, lead archetypes, and test scenes are drawn directly onto an HTML5 canvas at 1200×675 pixels for pitch export.
The Chemistry Index, tension labels, and greenlight readiness metrics are deterministic heuristic formulas built for creative pitching workflows. They do not simulate market testing, talent scheduling availability, audience sentiment analysis, or studio financial risk models.
Select the Fourth Wing preset (Friction 98%, Trust 85%, Physicality 96%, Stakes 99%). The Chemistry Index calculates as (98 × 0.25) + (85 × 0.30) + (96 × 0.30) + (99 × 0.15) = 24.5 + 25.5 + 28.8 + 14.85 = 93.65, displayed as '93.6 / 100' with the rating 'Explosive Dual Lead Sync'. Because friction (98) exceeds trust (85), the Tension Dynamic assigns 'High Spark / Volatile' with 'Banter-Driven Pace' instead of the dual-high 'Friction ⇌ Care' tier.
The script calculates the composite Chemistry Index using the formula: chemIndex = (friction * 0.25) + (trust * 0.30) + (physical * 0.30) + (stakes * 0.15). If the resulting index is 90 or above, it reports 'Explosive Dual Lead Sync'; 80 to 89 displays 'High-Voltage Tension'; 70 to 79 displays 'Solid Narrative Harmony'; and below 70 indicates 'Needs Rehearsal Polish'.
Tension categorization checks whether both friction and trust exceed 85 to assign 'Friction ⇌ Care' (Golden Rivals-to-Lovers Arc). If that condition is not met, it compares friction and trust directly: higher friction assigns 'High Spark / Volatile' (Banter-Driven Pace), while higher or equal trust outputs 'Deep Intimacy Focus' (Character-First Vulnerability).
Every input change re-triggers renderDeck(), which draws a themed linear gradient background, platform format badges, book source citations, two lead actor profiles with automated multi-line tag wrapping, and a benchmark rehearsal quote on a 1200×675 canvas element. The canvas buffer is transformed into a downloadable PNG object URL via HTMLCanvasElement.toBlob().
