How to Play 4K Videos on iPhone iPad?

Can 4K UHD Videos Be Played on iPhone 12 or iPad, iPad Air 3, iPad Pro, iPad Mini 5?

- I have a 4k camera and have only ever been able to play back through my 4K TV. Is there any way to play 4K UHD videos on iPhone or iPad? I had tried many different video player apps on my iPad Air but none of them worked perfectly.

Since iPhone 6/6S, users are able to shoot videos in 4K resolution. Since then, Apple users are wondering if they can watch videos at higher resolutions on iPhone or iPad. Now the latest iPhone 12 and iPad Pro feature Apple A11 Bionic and M1 chip, so users should be able to play 4K videos on iPhone iPad without error. Disappointedly, there are users who can't watch 4K on iPhone iPad successfully. Why?

Part 1 Why iPhone iPad won't Play 4K UHD Video?

1. Low Display Resolution

Before you play 4K videos on iPhone or iPad, you should know that not all the displays of iPhone iPad supports 4K resolution:

  • iPhone 12: 2,532x1,170 pixels at 460ppi for iPhone 12/Pro, 2,340x1,080 pixels at 476ppifor iPhone 12 mini, and 2,778x1,284 pixels at 458ppi for iPhone 12 Pro Max
  • iPhone 11 Pro Max: 2688 x 1242 pixels at 458 ppi, and 1792-by-828-pixel resolution at 326 ppi for iPhone 11
  • iPhone XR: 1792-by-828-pixel resolution at 326 ppi
  • iPhone X: 2436-by-1125-pixel resolution at 458 ppi
  • iPhone 8 Plus: 1920-by-1080-pixel resolution at 401 ppi
  • iPhone 7: 1334-by-750-pixel resolution at 326 ppi
  • iPad 7 screen resolution: 2160-by-1620-pixel resolution at 264 ppi
  • iPad Air 3 screen resolution: 2224-by-1668 resolution at 264 ppi
  • 4K resolution: 3840×2160 (16:9) or 4096x2160 (17:9)

2. Unsupported Video Format

Sometimes, the 4K videos come in an format that is not supported by iPhone. Therefore, it will result in iPhone iPad not playing 4K videos. To be specific:

  • The video formats supported by iPhone iPad include: HEVC, H.264, MPEG‑4 Part 2, and Motion JPEG
  • 4K video formats include: MP4, HEVC, MKV, MTS/M2TS, AVCHD, XAVC, MXF, AV1, VVC, etc.

3. 4K Large Size

4K video takes way much space. True 4K film needs more data storage, at least 100 gigabytes. If you're using an iPhone or iPad with a less-powerful chip, or low storage, the 4K video playback on it will be painful. In fact, on the displays of iOS-devices, you can hardly tell 4K apart from 1080p screen due to the pixel density. So 4K videos can be played on iPhone or iPad after compressed and converted to iPhone supported video formats, in 1080p, at 4:3 or 16:9. .
