How to Upload 4K Video to YouTube from PC/iPhone 6s/7

Accustomed with the super-high definition, crisp image quality and vivid color reproduction, you may have fallen in love with your 4K camcorder. Besides, with Apple supporting 4K video recording since iPhone 6S, more and more people have the material as well as desire to share their 4K videos on the video sites like YouTube and Facebook.

However, uploading your 4K videos to YouTube is not that easy. After countless failure, you may wonder, why on earth can't my 4K videos be uploaded to YouTube?

To begin with, you need to figure out what 4K YouTube video settings are. In fact, there are three basic factors that will decide whether your uploading is going to be successful or not: video file formats, size, and frame rate. YouTube now accepts 8 video formats to be uploaded, including MOV, MP4, AVI, WMV, FLV, 3GP, MPEGPS and WebM, supports 8K and 4K resolutions and file size of 2GB. Videos should not be longer than 15 minutes.

Now most 4K videos are XAVC (.MXF) or XAVC S (.MP4) videos which are not supported by YouTube, therefore, if you want to upload it to YouTube, firstly you need to convert it to supported formats.

In the following parts, I am going to introduce to you how to carry out the converting exactly.

Part 1. Upload 4K video from your computer to YouTube

In order to convert 4K video on your computer to other formats, we need to seek help to video converting software.

Part 2. Upload recorded 4k videos from iPhone 6s to YouTube

Generally, sharing a video on iPhone requires just a tap on the sharing icon and another tap on the YouTube icon, but that doesn't fully apply to 4K video. For whatever reason, iOS YouTube up loader allows you to upload 720p and 1080p videos to YouTube perfectly, but if you try to upload a 4K video directly by sharing icon, it automatically drops down the quality to standard definition.

Therefore, to upload recorded 4K video in your iPhone 6S with perfect quality, you could transfer 4K video to your computer and then upload it from your PC to YouTube.
