With thousands of pixels being involved 4k resolution take its place at the top.

4k video file size

Moreover, with this fact we can clearly say that to be able to save a full length 4k film we need at least a couple of terabyte hard disk. However, due to the fact that the 4k video file size is too large to watch, sometimes you feel the need use professional 4k players to watch them.

4K videoLooking through some 4k video sample using the 4k video format, the 4k superiority is immediately seen compared with 720p and 1080p. It is very just to say that it is truly an Ultra HD, from the detailed images to bigger projection surface visibility. By using the 4k video sample as a basis, it can be easily concluded that this type of resolution can take viewing to a new level and it will continue to reign the battle of resolution for many years to come. On the other hand, the limitation that 4k may be facing is the fact that producing a 4k film requires high-end expensive digital cameras that can capture in such a powerful resolution. And for some 4k video formats that hosted on YouTube and other streaming services, it will spend a great deal of time loading. In this way, it’s suggested to download 4k video on your hard drive for offline playback. Even more, some customers would like to burn 4k to their DVDs for later collection. Maybe your downloaded 4k video is not the DVD compatiable format. Given this, a professional 4k video converter really comes in handy.
