I've heard a lot about 4K UHD like 4K TV, 4K video, 4K cams, etc. but I still don't have any of them. I want to download some samples of 4K video to see how 4K resolution performs. Where can I free download true 4K video samples effortlessly? Additionally, I probably need to work with 4K in the near future, and I'm interested in 4K video editing. I use Windows 8 and my desktop is Dell XPS X8500-4211BK. Can anyone suggest the best hard system for 4K sample video editing?
4K Ultra HD resolution has 8 million pixels and it's four times of the resolution of Full HD (also known as 1080p). Currently 4K is becoming more widely available online such as YouTube, Netflix and Amazon. If you wish to download 4K sample from YouTube, you can try WinX HD Video Converter Deluxe. It enables you to free download 4K, 8K, 1080P HD video from YouTube, Vimeo, Dailymotion, Metacafe and more easily and steadily on Windows OS and in the mean time, this 4K YouTube downloader is capable of converting 4K Ultra HD and 8K FUHD sample video to AVI, MP4, WMV, FLV, 3GP, MKV, MTS, MOV, MP3, etc.
The minimum requirement for 4K sample video editing for graphic card is GeForce GTX 650 that performs better than GT 640. Most importantly, GTX 650 supports 4K external displays while GT 640 built in your desktop does not. If you want to edit 4K video sample smoothly, you may need a stronger graphic card such as GeForce GTX 770. And 4K sample video editing also needs a 4K monitor which is capable of displaying 4K resolution.
