Use it when building a video from a description and when you need frame-based animation rules that avoid render crashes. **Install:** ```bash npx degit https://github.com/hassancs91/claude-faceless-shorts-creator/tree/main/.claude/skills/vidtsx-2d-generator ~/.claude/skills/vidtsx-2d-generator ``` ## README # VidTSX 2D Video Generator Generate production-ready 2D TSX video files for VidTSX from a description of a shot or video. The files are Remotion compositions that VidTSX renders frame-by-frame, so correctness matters more than cleverness: a single non-monotonic `interpolate` range or a stray `useState` will crash the render. This skill covers **2D motion graphics**. 3D work (`@remotion/three` / React Three Fiber) is out of scope. ## How to use this skill 1. **Clear single shot** → generate the `.tsx` file directly. 2. **Complex, multi-shot, or visually ambiguous request** → confirm the shot breakdown or visual direction in one short message first, then generate. Don't over-ask; a one-line confirmation is enough. 3. **Deliver as an actual `.tsx` file**, not inline code. These TSX components always exceed 20 lines, and the user edits these files directly. Default to **one shot per file** (atomic, easy to edit) unless the user asks for a single combined deliverable. 4. The file contains **only the component code** — the structural section comments below are welcome, but no markdown fences, no prose explanations inside the file. 5. **Render it and look before calling it done** — see [Verify the render](#verify-the-render-do-not-skip). A shot you have only reasoned about is not finished; a still (and, for reveals/scrolls, frames at each cue) is the bar. --- ## Output spec ### Dimension presets | Format | Width | Height | Use case | |------------|-------|--------|----------------------------| | horizontal | 1920 | 1080 | YouTube, presentations | | vertical | 1080 | 1920 | TikTok, Reels, Shorts | | square | 1080 | 1080 | Instagram feed | ### Defaults - **Format:** horizontal (1920×1080) - **Duration:** 5 seconds - **FPS:** 30 - **Style:** minimalist (see `references/style-presets.md`) --- ## Mandatory file structure Every generated file follows this skeleton. The labeled section comments are intentional — they keep large files navigable. ```tsx import React from 'react'; import { useCurrentFrame, useVideoConfig, interpolate, Easing, AbsoluteFill, Sequence, } from 'remotion'; // ============================================================================= // COMPOSITION CONFIG // ============================================================================= export const compositionConfig = { id: 'ComponentName', // PascalCase only — NO hyphens or underscores durationInSeconds: 5, fps: 30, width: 1920, height: 1080, }; // ============================================================================= // STYLE CONSTANTS // ============================================================================= const COLORS = { primary: '#6366f1', secondary: '#8b5cf6', accent: '#06b6d4', background: '#0f0f23', text: '#ffffff', } as const; const TYPOGRAPHY = { fontFamily: 'Inter, system-ui, sans-serif', } as const; const EASINGS = { easeOut: Easing.bezier(0.33, 1, 0.68, 1), easeIn: Easing.bezier(0.32, 0, 0.67, 0), easeInOut: Easing.bezier(0.37, 0, 0.63, 1), overshoot: Easing.bezier(0.34, 1.56, 0.64, 1), } as const; // ============================================================================= // PRE-GENERATED DATA (computed once at module level, NOT during render) // ============================================================================= const seededRandom = (seed: number): number => { const x = Math.sin(seed * 9999) * 10000; return x - Math.floor(x); }; // ============================================================================= // MAIN COMPONENT // ============================================================================= const ComponentName: React.FC = () => { const frame = useCurrentFrame(); const { fps, durationInFrames, width, height } = useVideoConfig(); return ( {/* Content */} ); }; export default ComponentName; ``` Swap `ComponentName` for a PascalCase name describing the shot, set the `COLORS` block from the chosen style preset, and set `width`/`height`/`durationInSeconds`/`fps` from the request. --- ## Correctness rules These are not stylistic preferences — they are what makes a render succeed. VidTSX (via Remotion) renders each frame by calling the component at a fixed frame number. There is no event loop, no persistence between frames, and no wall-clock time. Anything that assumes those things will break. ### Animation is frame-based, always - Drive **all** motion from `useCurrentFrame()` + `interpolate()`. - **Never** use `useState`, `useEffect`, `setTimeout`, `setInterval`, or CSS animations/transitions. They don't fit the frame-by-frame model and produce broken or non-deterministic output. - For anything random or procedural, use `seededRandom` (or an equivalent seeded function) so every render of a given frame is identical. Pre-generate particle/random arrays **at module level**, never inside the render function — recomputing per frame causes flicker. - Stagger animations so elements enter in sequence rather than all at once. It reads better and is the expected look. ### interpolate — input ranges must be strictly increasing `interpolate`'s input range has to be strictly monotonically increasing. Duplicate or descending values throw at runtime. ```tsx // ✅ Correct interpolate(frame, [0, 30, 60], [0, 1, 0]); // ❌ Throws — input range descends interpolate(frame, [60, 30, 0], [0, 1, 0]); ``` To **reverse** a mapping, flip the *output* range, never the input range: ```tsx // ✅ Correct — maps 0→100, 1→0 interpolate(value, [0, 1], [100, 0]); // ❌ Wrong interpolate(value, [1, 0], [100, 0]); ``` For index-based timing, make sure `startFrame < endFrame` and always clamp: ```tsx const startFrame = index * 30; const endFrame = startFrame + 30; interpolate(frame, [startFrame, endFrame], [0, 1], { extrapolateLeft: 'clamp', extrapolateRight: 'clamp', }); ``` **Always** pass `extrapolateLeft: 'clamp'` and `extrapolateRight: 'clamp'` unless an unbounded value is genuinely wanted — without them, values shoot past their range before/after the keyframes. ### Easing — use Easing.bezier(), never wrapper syntax Wrapper forms like `Easing.out(Easing.cubic)` crash. Define named beziers once (see the `EASINGS` block in the skeleton) and reference them: ```tsx // ❌ Crashes Easing.out(Easing.cubic); Easing.in(Easing.quad); // ✅ Correct interpolate(frame, [0, 30], [0, 1], { easing: EASINGS.easeOut, extrapolateRight: 'clamp', }); ``` ### chroma-js — namespace import only ```tsx // ✅ Correct import * as chroma from 'chroma-js'; const color = chroma('#00bfff').brighten(0.5).hex(); // ❌ Wrong — "chroma is not a function" import chroma from 'chroma-js'; ``` ### @remotion/paths — only the real functions exist These helpers **do not exist** and must never be used: `makeCircle()`, `makeRect()`, `makeTriangle()`, `makeLine()`, `makePie()`, `makePolygon()`, `makeEllipse()`, `makeStar()`. Only these imports are valid: ```tsx import { evolvePath, getLength, getPointAtLength, getTangentAtLength } from '@remotion/paths'; ``` Write SVG path strings by hand and animate them with `evolvePath`: ```tsx const circlePath = 'M 50 10 A 40 40 0 1 1 49.99 10 Z'; const rectPath = 'M 0 0 L 100 0 L 100 50 L 0 50 Z'; const linePath = 'M 0 0 L 100 100'; const { strokeDasharray, strokeDashoffset } = evolvePath(progress, rectPath); ``` ### Composition ID `compositionConfig.id` is **PascalCase only** — no hyphens, no underscores (e.g. `ProductReveal`, not `product-reveal` or `product_reveal`). --- ## Layout ### Safe zones - **Top 10%:** reserve for platform UI. - **Bottom 15%:** reserve for captions/buttons. - Keep primary content between **25%–75%** vertically. ### Centering helper ```tsx const centered: React.CSSProperties = { position: 'absolute', top: '50%', left: '50%', transform: 'translate(-50%, -50%)', }; ``` --- ## Typography | Element | Size | Weight | |---------------|------------|---------| | Headlines | 72–120px | 700–900 | | Subheadlines | 36–48px | 500–700 | | Body | 28–36px | 400–500 | Always set `margin: 0` on text elements — browser defaults push layouts off-center. --- ## Style presets When the user names a style, load its palette and characteristics from **`references/style-presets.md`** and drop the `COLORS` object into the skeleton. The six presets are: **minimalist** (default), **memphis**, **neo-brutalism**, **glassmorphism**, **neon/cyberpunk**, and **corporate**. If no style is named, use minimalist. --- ## Verify the render (do not skip) A shot is not done until you have **looked at it**. After writing the `.tsx`, render at least one still and open it — never hand over a shot you have only reasoned about. Rendering succeeds and the numbers look right, yet text overflows its card, an image is cropped at the wrong crop, an element is off-screen, or two things overlap. Only a screenshot catches these. - Render a still (e.g. `node scripts/render-all.mjs --still --scale=1 `) and Read the PNG. - For time-based reveals (elements entering on a cue, scrolls, staged phases), a single 60%-of-duration still is not enough — render the full clip and pull frames at each key moment (`ffmpeg -ss -i out/.mp4 -frames:v 1 f.jpg`), or render stills at several offsets. Verify the state at each cue, not just one frame. - Check specifically: images fit their slot (no important content cropped; prefer `objectFit: contain` on a matching background for heterogeneous real images), text is not clipped or overflowing, nothing is off the safe area, and each animated element is actually visible when it should be. - If it is composited over other footage, also spot-check a frame from the final baked output, not just the isolated shot. Fix what the screenshot reveals, then re-render and look again. Treat "I rendered it and it looks correct" — with the frame shown — as the bar for done. --- ## Final output Generate the complete `.tsx` file and nothing else inside it — no surrounding markdown, no commentary before or after the code in the file itself. A short one-line note in chat when handing over the file is fine.
