The first thing to ask is “What is 4k video”?
4k Video (H265) is a short name for ultra high def video. It is twice the resolution of H264 or known as HEVC. It is early days with this technology but its being adopted by companies like Amazon and Netflix. With 4k comes very high quality but also even with compression encoding, still makes a large video file. This can be problematic with streaming so you need very high powered servers and network pipe.
4k video can also be used to stream video to your ROKU Channels. 4k TVs are now being shipped but there is not much in the way of content (yet) and that’s where you come in.
