Have some 4K files and wanna transfer and watch these 4K files on iPhone or iPad when you’re outside? In this article, we will show you how to play 4K on iPhone/iPad smoothly. Read on to learn a full guide.
Which iPhone/iPad models support 4K video?
From Apple’s official website, we get the information that you can view compatible 4K video on the following iPhone or iPad models:
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.
How to 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.
