What is 4K?

At its most basic, the term refers to a resolution of 3840 x 2160, which some call 2160p for short. Also, 4k is a nice, even multiple of "Full HD" resolution (1080p), too. 3840 x 2160 is exactly double 1920 x 1080 in both width and height. So for every pixel on a 1080p TV, there are four pixels on a 4K TV. 4K UHD gives you a better viewing experience for impressive sharpness and clarity. That’s why an increasing number of people turn to 4K ultra HD video indeed.

Transcoding, compressing, editing, playing 4K UHD videos comprise important parts of 4K processing. During the process, you may meet a lot of obstacles to stop you playing or editing the UHD files. For example, 4K video takes too much storage space and consume a great deal of bandwidth are also the significant causes for the advent of 4K video processing.

4K Advantages VS 4K Disadcantages

Talking about the 4K advantages, it is obvious that the 4K video offers viewer the wonderful audiovisual experience. Its advantages are needless to say anymore. The next thing you have to make it clear is that how to get over its weakness?

1. 4K Video Playback Failure

No everyone has the luxury of buying a blu ray player to watch the UHD BD, more people prefer to watch 4K videos on Mac and Windows desktop. This means you need go over a certain time of hardware replacement as 1080p HD first appeared, otherwise you’ll encounter a number of problems like 4K get choppy or stuttering, laptops get overheated, 4K video images freeze and even 4K UHD fails to play. Briefly, hardware matters a lot on 4K video playback.

2. Complex 4K Video Formats

We can get 4k video from many places: downloaded from Youtube, Netflix; shot with Sony/Panasonic/Canon camcoders; captured via DJI 4K drones…And the 4K video could be wrapped in MKV, MP4, XAVC, AVCHD, MOV container with various codec, therefore this bring a new question: you can smoothly and successfully play or edit them on any deivces or non-linear editing software.

3. File Storage Unit

4K footage takes up a lot more space than full HD – up to four times more, in fact. A single minute of video on some prosumer 4K-capable video cameras can weigh in at more than one gigabyte.

4. 4K Video Editor and Sharing

Editing 4K footage doesn’t just require a powerful computer, you’ll also need specialized video editing software. For the best results we’d recommend more full-featured software like Adobe’s Premiere Pro, or Apple Final Cut Pro X. If you want or need to share your work in full-resolution 4K you can easily share the files directly via your prefered online cloud storage service, but depending on your Internet connection speed, upload and download times will probably be very lengthy. 4K video is still not very well-supported by online video hosting services, but Vimeo allows you to make 4K footage available for download and YouTube offers 4K streaming (albeit highly compressed).

To sum up, 4K video processing could bring us a lot of questions. Is there any solution to solve this problem? Of course. Here we highly recommend you Pavtube Video Converter Ultimate for Windows/Mac (best 4K Video Converter Software Review) which allows you to transcode 4K MKV, 4K AVI, 4K XAVC, 4K AVCHD, even 4K Blu-ray to 4K MP4 in H.264/H.265 codec. By the way, you can compress 4K to 1080p by adjusting the video resolution, bit rate. It gives you massive optimized device presets for Apple devices, Android devices, non-linear editing software, and others. You can output "Apple InterMediate Codec(AIC) (*mov)" for iMovie, "Apple ProRes 422(*.mov)" for Final Cut Pro, "MPEG-2(*.mpg)" for Premiere/Sony Vegas. When you import the 4K video into the software, you can preview it at once.
