Validate the diagnostic

Confirm the reported code matches this rule before you edit it.

Confirm the reported code matches react-doctor/remotion-stable-delay-render-handle. Compare it with the Before example and verify the same API, framework, and execution context. Treat it as a false positive only when one of those conditions differs.

Compare the code

The corrected pattern shows a focused way to address the diagnostic.

Reported pattern

import { continueRender, delayRender } from "remotion";

const Scene = () => {
  const renderHandle = delayRender();
  return <Content onReady={() => continueRender(renderHandle)} />;
};

Corrected pattern

import { useDelayRender } from "remotion";
import { useState } from "react";

const Scene = () => {
  const { continueRender, delayRender } = useDelayRender();
  const [renderHandle] = useState(() => delayRender());
  return <Content onReady={() => continueRender(renderHandle)} />;
};

How to fix

Use the corrected pattern as a reference. Preserve behavior that the rule does not require you to change.

Copyable fix prompt

Copy this self-contained prompt into your coding agent after you confirm the diagnostic.

Fix every confirmed react-doctor/remotion-stable-delay-render-handle diagnostic in the current repository. Required change: - Prefer useDelayRender(), or initialize delayRender() once with useState(() => delayRender()).

Reference transformation:Before:

import { continueRender, delayRender } from "remotion";

const Scene = () => {
  const renderHandle = delayRender();
  return <Content onReady={() => continueRender(renderHandle)} />;
};

After:

import { useDelayRender } from "remotion";
import { useState } from "react";

const Scene = () => {
  const { continueRender, delayRender } = useDelayRender();
  const [renderHandle] = useState(() => delayRender());
  return <Content onReady={() => continueRender(renderHandle)} />;
};

Constraints: - Confirm the reported code matches the Before pattern. - Make the smallest change that fixes the root cause. - Preserve behavior and interfaces unrelated to this diagnostic. - Reuse existing project components, utilities, and conventions. - Do not introduce render-phase side effects, render-phase state updates, or Hooks rule violations. - Adapt identifiers and framework details instead of copying blindly. - Do not disable the rule or suppress matching code. - Confirm this rule is enabled for the project: remotion:4. Verification: - Run focused tests for the changed behavior. - Run React Doctor and confirm this diagnostic no longer appears. - Report the files changed and any checks you could not run.

react-doctor/rendering-conditional-render: Change to `{items.length > 0 && <List />}` or use a ternary: `{items.length ? <List /> : null}`
react-doctor/rendering-hydration-mismatch-time: Wrap dynamic time/random values in useEffect+useState (client-only) or add suppressHydrationWarning to the parent if intentional
react-doctor/require-render-return: Require class component render() methods to return a value — a missing return renders nothing.
react-doctor/rerender-dependencies: Extract to a useMemo, useRef, or module-level constant so the reference is stable
react-doctor/rn-animate-layout-property: Animate `transform: [{ translateX/Y }, { scale }]` and `opacity` instead of layout props — layout runs on the JS thread; transform/opacity run on the GPU compositor
