iPhone Won't Play Videos on Apps (Facebook, Splice, Clips, etc) You have to convert the frame rate to Apple 30fps beforehand.ģ. For example, iPhone blocks any video in 100fps and even 29.99fps, while Mavic 30fps is actually more like 29.99fps instead of 30fps. Frankly, certain iDevices have specific limitations and have put a block on frame rate higher or lower being copied into the system folders or imported through the lighting connector.

Higher Frame rate: iPhone users are disappointed to see some footages cannot load or play on iPhone.

Check what video quality your iDevice can play > To accommodate the process, the 4K videos of higher resolution shall be converted to a lower resolution like 1080p or 720p, if you have older models. Secondly, right now, only iPhone 8 (Plus), iPhone X, iPhone XR, iPhone XS (Max), iPad Pro and iPhone 11 series in 10.5-inch, 12.9-inch, 11-inch and 12.9-inch can play 4K and HDR videos flawlessly.

This is typically because playing 4k video consumes resources like processor, RAM and graphic memory. High Resolution: 4K video playback problem on iPhone such as stuttering or lags happens as a result of the iPhone's processing power.Some camera is equipped with settings purpose built for higher quality but resulting in big size, such as GoPro's Protune, make sure to turn off the feature to ensure an easier playback on iPhone later. Or else, make sure your iPhone has double the required space available for 4K video playback. You must shrink video size by lowering bitrate for smooth video playback on iPhone. Lower bitrate means that iPhone will have less work and easier time to do when playing back the video. Technically, 10 min 2.7K60fps GoPro video will take up around 4.8GB storage space, let along the 4K60fps video.

But the file size turns out to be overly big since the max bitrate reaches to 60mbps.

High bitrate or big file size: Some user suggests 2.7k60fps cannot play on iPhone despite short length.

Here are the majorly 2 reasons why your iPhone won't play these videos. These videos are commonly filmed HEVC 4K 60fps, 2.7k 120fps and 1080p 240fps. They are told the 4K videos are unsupported and won't play on iPhone or iPad and the resolution or FPS need to be lower.

Many a iPhone user reported a playback failure of 4k videos filmed by GoPro, DJI Mavic or other cameras.

Reason 3: Problem with 4K video, higher frame-rate video or oversized video
