Credit to @marcusstenbeck for creating this snippet.

This snippet is useful if you want to isolate the global styles of your homepage from the global styles of the <Player>.

- import { Player } from '@remotion/player';
+ import { IframePlayer } from 'path/to/IframePlayer';

- <Player {/* ... */} />
+ <IframePlayer {/* ... */} />

import { Player, PlayerProps, PlayerRef } from "@remotion/player";
import React, { forwardRef, useEffect, useRef, useState } from "react";
import ReactDOM from "react-dom";
import { AnyZodObject } from "zod";

const className = "__player";
const borderNone: React.CSSProperties = {
  border: "none",
};

const IframePlayerWithoutRef = <T extends Record<string, unknown>>(
  props: PlayerProps<AnyZodObject, T>,
  ref: React.Ref<PlayerRef>
) => {
  const [contentRef, setContentRef] = useState<HTMLIFrameElement | null>(null);
  const resizeObserverRef = useRef<ResizeObserver | null>(null);
  const mountNode = contentRef?.contentDocument?.body;
  useEffect(() => {
    if (!contentRef || !contentRef.contentDocument) return;
    // Remove margin and padding so player fits snugly
    contentRef.contentDocument.body.style.margin = "0";
    contentRef.contentDocument.body.style.padding = "0";
    // When player div is resized also resize iframe
    resizeObserverRef.current = new ResizeObserver(([playerEntry]) => {
      const playerRect = playerEntry.contentRect;
      contentRef.width = String(playerRect.width);
      contentRef.height = String(playerRect.height);
    });
    // The remotion player element
    const playerElement = contentRef.contentDocument.querySelector(
      "." + className
    );
    if (!playerElement) {
      throw new Error(
        'Player element not found. Add a "' +
          className +
          '" class to the <Player>.'
      );
    }
    // Watch the player element for size changes
    resizeObserverRef.current.observe(playerElement as Element);
    return () => {
      // ContentRef changed: unobserve!
      (resizeObserverRef.current as ResizeObserver).unobserve(
        playerElement as Element
      );
    };
  }, [contentRef]);
  const combinedClassName = `${className} ${props.className ?? ""}`.trim();

          // @ts-expect-error PlayerProps are incorrectly typed
          <Player<AnyZodObject, T>
            {...props}
            ref={ref}
            className={combinedClassName}
          />,
          mountNode
        )}
    </iframe>
  );
};
export const IframePlayer = forwardRef(IframePlayerWithoutRef);
