  "account": "When the demo is released, people often ask whether their agent should write VidScript or TypeScript. The honest answer is to use the Language Short promos, human edits, and templates in the public @scenerok/sdk README. Both generate the same intermediate timeline for preview and rendering, making this the key feature. This guide explains how to choose without blindly adopting either side.\n\nVidScript: Written in a way that resembles a script, it focuses on readable intent. Imports pull generative providers, inputs declare existing footage, time ranges place layers on a clock, and compile-time slots resolve model calls before composition. The output sets the container and destination. Users appreciate VidScript because they can review differences in a PR like copy, not a graph of objects. Brand and motion designers can learn the shape without needing to adopt the full TypeScript toolchain, and templates stay legible with obvious slots and parameters.\n\nAgents may sometimes prefer TypeScript when creating linear launch reels, as a DSL reduces rope to hang yourself. Fewer syntactic degrees of freedom mean fewer invalid programs, and diagnostics map cleanly onto lines of intent. If the job is a 15-second reel with a hero clip, a voiceover, and an end card, start in VidScript and do not open with a framework. The SDK is suitable when videos deal with multiple SKUs, branching explainer paths from a CMS, grid layouts filled by loops, or agent refactors that rearrange markers arithmetically. TypeScript provides real control flow, tests, module imports, and the same toIR() exit. The public surface includes timeline construction, probing helpers, text/audio factories, grid areas, and transitions.\n\nBoth languages share one IR (Intermediate Representation) but have different authoring developer experiences (DX). Authoring is plural, but the timeline meaning is singular. Features land in IR semantics first, then in both frontends when relevant. Validate the IR before rendering using scenerok validate style checks, which apply to both the public CLI behavior. Showcase examples can ship as .vid or .ts folders; forks should not be surprising at render time.\n\nThis approach is similar to how compilers work, with multiple languages converging on a single machine model: the timeline and render contract. Here's a decision guide for agent builders:\n\n- Use VidScript for small linear durations, human editing, parameterizing templates with a few slots, or minimizing ways to be wrong.\n- Use @scenerok/sdk when generating many related scenes from data, when timing depends on probed media durations or arithmetic, if you need loops, conditionals, or shared libraries, or when the agent must unit-test pieces of assembly.\n- Use both languages in one shop for humans to tune VidScript templates for taste while agents expand parameterized campaigns in TypeScript. CI should validate IR equivalence on golden fixtures to ensure both produce the same structure for the same intent.\n\nSome pitfalls to avoid include using the SDK for everything, resulting in overly complex code for simple tasks; using VidScript with pretend-loops; using generative calls without pins; and teaching agents only prompts without teaching them to validate and render. Testing video programs is challenging because you cannot unit-test taste. However, you can test structure, such as duration bounds, required layers, brand lockup, and absent forbidden models. Make pinning part of the workflow from the beginning. Lastly, teach agents to wire MCP/CLI skills to the edit-validate-preview loop, not just to emit text.",
