About Square HD Resolution

720×720 square video provides an intermediate quality tier between 480×480 and 1080×1080. The resolution offers HD-quality square content suitable for social media feeds where 1080×1080 might be excessive but 480×480 appears too low-resolution. Some platforms use 720×720 as a middle-tier option in adaptive streaming or for users on bandwidth-constrained connections.

Playwright / Cypress

// Playwright: assert the browser sees real video metadata.
const metadata = await page.locator('video').evaluate((node) => {
  const video = node as HTMLVideoElement
  video.src = 'https://placeholdervideo.dev/720x720'
  video.load()
  return new Promise<{ width: number; height: number; duration: number }>((resolve) => {
    video.addEventListener('loadedmetadata', () => {
      resolve({
        width: video.videoWidth,
        height: video.videoHeight,
        duration: Math.round(video.duration)
      })
    }, { once: true })
  })
})

expect(metadata).toEqual({ width: 720, height: 720, duration: 10 })

// Cypress: attach the same fixture URL in an existing player test.
cy.get('video')
  .invoke('attr', 'src', 'https://placeholdervideo.dev/720x720')
  .then(() => cy.get('video')[0].load())

Technical Considerations

Square 720p contains 518,400 pixels, allowing bitrates around 1.5-2.5 Mbps for good quality. Files run approximately 2-3 MB for 10 seconds. The resolution is universally hardware-accelerated and displays sharply on most modern devices.
