How to Resize and Convert 4K Video to MP4 flawlessly with WinX HD Video Converter Deluxe

The internet exploded when 4K made its entry. We not only have devices which can shoot in 4k but also have 4K TV. The best part is that it is not just about resolution; it is also about the details it can capture in every footage. While the 4k recording is still limited to high-end devices, there are many, including  GoPro, DJI, DSLRs, iPhone, or Android devices.

That said, while 4K devices are fantastic, playing them back doesn’t work smoothly on all the devices. When playing 4K videos you may encounter various problems including choppy 4K playback in VLC or iMovie, frame drops, sound and video out of sync, no sound on video, blurry playback quality, failed to play due to format issue, etc.

Lastly, 4K videos take a lot of space. 4K is four times the 1080P video size.  If you are planning to store all the 4K videos you shot, you will need a lot of space. Not everyone can put in a lot of money for that amount of storage space. While uploading to YouTube is one option, but keeping the original video is equally important.

So the best solution for 4K size and playback issue is to compress & convert 4K to most-compatible MP4. One such tool to convert is  WinX HD Video Converter Deluxe.
