Fast Refresh not working

If the Remotion Preview does not update after you have updated your file, it is usually due to one of two reasons:

1

Preview server disconnected: This happens when you quit the process that was started when running npx remotion preview, usually using Ctrl+C or by quitting the terminal.

2

Mismatched capitalization in the filenames: Ensure that the capitalization of filenames is correct in imports. For example, if your filename is MyComp.tsx, but you import it using import {MyComp} from "./myComp.tsx", Fast Refresh may break.

This is a bug in Webpack for which we've filed an issue.
