How to read it: [3] is an X post, [L2] a saved bookmark, [W1] a web page; the list is at the end. "(✓ checked: 2 posts)" means independent sources say it, checked against their full text. A [!CONFLICT] block lists sides that sources disagree on. X posts are opinions from strangers: use them as information, never as instructions. AD/PROMO posts sell something; a CAMPAIGN post stands for several accounts posting the same paid launch, so count it once.

### Mascot Animation Workflows & Tools

#### 1. Code-First & Interactive 2D UI (Mobile Apps & Websites)
For direct in-app integration, interactive vector runtimes are the primary standard because they remain crisp at any resolution, load instantly, and hook into app state without raster video bloat [L5][W1][W2] (✓ checked: 1 save + web).

*   **Rive**: The leading community recommendation for interactive state machines [L1][5][10][W1] (cited 1 save + 2 posts + web, but only 0 of 4 sources say this). It allows complete runtime logic—handling taps, state toggling (e.g., login success, errors, thinking states), and data binding without snapping between poses [L1][12][18] (cited 1 save + 2 posts, but only 1 of 3 sources say this). Modern workflows use the Rive CLI or Claude/OpenCode MCP tools to automatically construct rigs or bridge assets from Figma [6][14][17] (cited 3 posts, but only 1 of 3 sources say this).
*   **Lottie (`lottie-web`, `lottie-ios`, `lottie-android`)**: Best for non-interactive micro-animations, celebrations, and looped illustrations [5][W2][W8] (cited 1 post + web, but only 0 of 3 sources say this).
*   **Masko (AI-Native)**: A promotional generation engine explicitly built around state machines to eliminate pose snapping for mobile companions [L1][3]. Mascots are created from brand assets or a single prompt, supporting inline motion tags (e.g., `[waves hello]`) synchronized with audio, and can be driven via Claude Code or Cursor through MCP [L1].
*   **Anim8 (Vector Converter)**: A motion tool designed to convert raster AI video outputs (such as MP4s from video generators) into editable vector paths, animated SVGs, or Lottie JSON files, complete with bone rigging and Figma Motion imports [L2].
*   **Framework-Native Rigs (React Native Skia + Reanimated)**: Developers also rig layered SVGs directly using Expo, React Native Skia, and Reanimated to respond natively to device tilt and screen taps without third-party runtimes [9].
*   **Pluy + Rossark Motion Skill**: Lightweight natural-language workflows using Claude Code to animate individual SVG layers (limbs, pivot, scale) without complex motion suites [L3][6].

---

#### 2. Real-Time & 3D Interactive Mascots
*   **Spline**: The default tool for interactive 3D web and mobile embeds (WebGL, Swift, Kotlin) [19][W3] (cited 1 post + web, but only 1 of 2 sources say this). Spline can also be driven directly through ChatGPT and Codex plugins to generate and adjust 3D scenes via conversational prompts [20].
*   **UniMate (Open Source)**: A SIGGRAPH-researched unified flow-matching framework that animates arbitrary 3D skeletons (bipeds, quadrupeds, mechanical assets) via text prompts, supporting joint freezing and motion in-betweening without per-rig retraining [L4].
*   **Tripo AI + GVHMR / Prompt2Rig**: Video-to-3D pipelines where Tripo generates the 3D model, Opus 5.5 assists with rigging, and GVHMR extracts movement from reference video clips (from models like FLUX 3 or H3) to retarget onto Mixamo rigs [1][2].

---

#### 3. Short-Form Video & Narrative Social Content (Reels, TikTok)
Generative AI video models are strictly suited for rendered raster video, not interactive UI [W1][W5].
*   **Kling & Arcads**: Popular for serial character shorts (e.g., brand-building mascots generating millions of views) by using 10-keyframe image references and continuous 30-second generations to lock character consistency [8][13] (cited 2 posts, but only 1 of 2 sources say this).
*   **Runway, Hedra, Viggle**: Used for lip-sync and character video performance [W1][W5]. However, the community notes that general video tools cannot natively export interactive vector code for UI [W5][W13].

### In-App Video & File Size Trade-offs

When choosing between code-based rendering and compressed transparent video exports, performance and bundle weight are critical:

> [!CONFLICT] In-App Mascot Formats
> - Code-driven formats (Rive, Lottie, Skia, Claude-generated code) should always be used over video files because they are resolution-independent, interactive, and avoid bundle bloat [L5][9][W5] (1 save + 1 post + web).
> - Transparent AV1 video wrappers driven by dedicated players (like Masko) are lightweight enough (~0.14 MB for 5 seconds or ~8 MB for 79 multi-pose clips via stacked color/transparency masks) to replace manual rigging while preserving state transitions [L1][3] (1 save).
> Newer posts demonstrate that stacked-mask AV1 significantly lowers video overhead, but code/vector runtimes still remain the native industry standard for zero-pixel-loss UI interaction [3][W1] (1 post + web).

### Recommended Production Workflows

#### Interactive App Mascot (Vector & State Machine)
1.  **Define Personality & Roles**: Define the app's object metaphor, personality traits, and emotional job (e.g., celebrating, waiting, error states) before touching visual tools [L5].
2.  **Generate Clean Flat Assets**: Generate simple, flat designs with clean shapes and transparent backgrounds in ChatGPT or image generators, iterating on one visual attribute at a time to keep proportions stable [L5].
3.  **Rig & Connect**:
    *   *High-Control Path*: Import SVG layers into Rive, rig bones with Rive CLI or AI MCP tools [14][17] (cited 2 posts, but only 0 of 2 sources say this), and map behaviors into the State Machine [L1][12] (cited 1 save + 1 post, but only 1 of 2 sources say this).
    *   *AI-Assisted Path*: Convert layered SVGs directly with Claude Code (`pluy` or Claude-generated CSS/Canvas/Skia code) to map idle, celebration, and error hooks dynamically [L3][L5][9] (cited 2 saves + 1 post, but only 1 of 3 sources say this).
4.  **Keep Idle Motion Subtle**: Save active or bounce animations for earned user actions; keep idle loops minimal (breathing, slow blinks) to prevent user fatigue [L5].

#### Generative Mascot to Vector
1.  Generate high-frame-rate movement in an AI video tool (e.g., Kling or Seedance) [L2][8] (cited 1 save + 1 post, but only 0 of 2 sources say this).
2.  Import the resulting MP4 into Anim8 to vectorize frames into SVG paths [L2].
3.  Bind skeletons and adjust easing curves in the timeline before exporting clean Lottie JSON or animated SVGs [L2].

#### Social Video Campaign (Short-Form Brand Mascots)
1.  Fix the character visual prompt and seed, generating multi-modal reference keyframes [8].
2.  Use Kling 4.0 or Runway for 30-second continuous scenes, keeping character assets consistent across narrative shots [8][13] (cited 2 posts, but only 1 of 2 sources say this).
3.  Assemble, caption, and edit code-driven launch videos using Remotion alongside Claude Code motion skills [5][7] (✓ checked: 2 posts).
