This means that if you are shooting videos in 4K, but have not yet upgraded to the most recent software (and face it, this can be extremely expensive), you need a way of converting that 4K video into a file that can be worked with in the program you have. Additionally, playing back 4K videos on non-supported devices is an issue now and into the future, until 4K viewing compatibility is more affordably available.
This 4K Video Converter takes your 4K ultra HD video and converts it for editing in popular video editing applications, so you can then view the video on regular televisions, iPad, smartphones and other devices that do not yet support native 4K viewing
