Minecraft version: 1.20.1 forge
So I'm using macbook pro(apple chip), when I try to render the replay, it said I didn't install ffmpeg

in the log, it shows this:

However, I've already installed ffmpeg on my laptop in the directory /usr/local/bin. When I ran /usr/local/bin/ffmpeg in the console, it run normally

I've also try to use the official replaymod to render a video in another version(1.21), it did works
