Playwright test videos

Hello, I'm running my playwright test locally with the following configuration, and I've enabled the video option and set it to "on," but even after running the test, I just see.png files under test-results, no videos have been generated. Is there something I'm overlooking in the configuration? Please assist.

import { devices } from '@playwright/test';
// eslint-disable-next-line @typescript-eslint/no-var-requires
require('dotenv').config();

const config: PlaywrightTestConfig = {
  testDir: './playwright-tests',
  globalSetup: require.resolve('./global-setup'),
  use: {
    storageState: 'combinedStorageState.json',
    channel: 'chrome',
    headless: true,
    screenshot: 'on',
    video: 'retain-on-failure',
    launchOptions: {
      // slowMo: 1000
    },
  },
  timeout: 300 * 1000,
  expect: {
    timeout: 30000,
  },
  fullyParallel: false,
  forbidOnly: !!process.env.CI,
  retries: 0,
  workers: 1,
  reporter: [['json', {  outputFile: 'test-results.json' }]],

  projects: [
    {
      name: 'chromium',
      use: {
        ...devices['Desktop Chrome'],
      },
    },
  ],
};

export default config;
