Play 4K Video on iPhone/iPad

Have just recorded some 4K footage with your 4K camera, apart from viewing the 4K footage on your 4K TV, you may also come the idea to transfer and watch them on your iPhone/iPad on the move. The following article will show you how to get different types of 4K video played on iPhone/iPad.

Can your iPhone/iPad handle 4K resolution video?

From Apple's official website, we get the information that you can view compatible 4K video on the following iPhone or iPad models:
iPhone 6, iPhone 6 Plus, iPhone 6S, iPhone 6S Plus, iPhone 7, iPhone 7 Plus, iPhone 8
iPad Air 2, iPad Mini 4, iPad Pro, New iPad 2017, iPad Mini 5

If you are using previous version of iPhone or iPad, then the device will automatically downscale 4K video to 1080p, which not ensure you a good result. The fact is that you can get clearer pictures when you choose to directly view videos with HD resolution on a iPhone or iPad that support maximum resolution of 1080p.

Play unsupported 4K video on iPhone/iPad

Sometimes, even if you try to play 4K video on those iPad or iPhone models that supports 4K resolution playback, you may still end up with failure. The main reason is both iPhone and iPad can only playback very limited 4K video file that meets the following standards:
- H.264 video up to 4K, 30 frames per second, High Profile level 4.2 with AAC LC audio up to 160 Kbps, 48kHz, stereo audio or Dolby Audio up to 1008 Kbps, 48kHz, stereo or multichannel audio, in .m4v, .mp4, and .mov file formats

Therefore, if you happen to own a 4K video with the codec or format of H.265, Prores, MXF, AVI, WMV, MKV, MOV, XAVC, XAVC S, etc, your iPhone or iPad will fail to open that video. In addition, sometimes, even if you have got a 4K video with compatible file format and codec, you may still encounter other playback issues due to the incompatible frame rate, bit rate, aspect ratio, sample rate, audio codec, etc. If you are looking for a comprehensive solution to fix all those format and settings incompatible issue, you can have a try at Pavtube iMedia Converter for Mac, which has full support for all the unsupported 4K format or codec listed above, You can not only use the program to produce iPhone or iPad playable 4K H.264 MP4, MOV or M4V file format, but also adjust other profile settings in the program's "Profile Settings" window to make them adapt with your iPhone/iPad best playback settings.

Adjust output video aspect ratio

Now all available iPhone and iPad models use a 4:3 screen display aspect ratio, however, the camera DCI recorded 4K video adopts an aspect ratio approximately 1.9:1 while the UHD 4K video adopts an aspect ratio of 16:9. When you try to view DCI 4K or UHD 4K video with incompatible aspect ratio on iPhone or iPad, there will be black bars around the video. The good news is that you can easily eliminate this problem by change output video aspect ratio with the "Crop" function in the video editing window.

How to Convert Unsupported 4K Video for iPhone/iPad Playing?

Step 1: Load 4K videos or movies.

Download the free trial version of the program. Launch it on your computer. Click "File" menu and select "Add Video/Audio" or click the "Add Video" button on the top tool bar to import source 4K videos or movies into the program.

If you choose to output to stereo audio or Dolby Audio, please set audio bit rate as 1008000bps and sample rate as 48000Hz.

Step 4: Adjust output video aspect ratio.

Go the "Crop" tab in the "Video Editor" Window, switch to the "Advanced Mode". To change output video aspect ratio, there are several aspect ratios for you to choose from, including 16:10, 16:9, 5:4, 4:3, 3:2, and 2:1, here, just choose iPad accepted 4:3 aspect ratio. Once you select the "Display aspect ratio", the "green crop frame" will keep this ratio to crop video and you are able to preview the final effect in real time. If you want to keep the same aspect ratio in your final output files, do remember to set the Video "Size (pix)" in "Settings" section as the same ratio as display aspect ratio.
