How to Compress and Convert 4K Video to MP4 on Windows for Free

The HD resolution is a thing of past as consumers have now moved to Full High Definition aka Full HD. At the same time, a majority of people prefer to watch videos and movies in 4K or Ultra High Definition (UHD). Recording 4K videos is not a big deal anymore as one can easily capture them with handheld devices like GoPro, DJI, iPhone, Android phones, and DSLRs. Though 4K undoubtedly offers incredible details and best viewing experience, it is not suitable for everyone.

For instance, if you’re watching 4K content on a laptop with low-end hardware or on a Full HD TV. In that case, you won’t be able to enjoy the true 4K quality because the playback device doesn’t have native 4K support. Hence, viewing 4K content on an old computer would result in a choppy playback, frequent frame drops and lags. In addition, the audio may be out of sync and the file may fail to play due to unsupported format. Needless to say, the large file size of 4K media will occupy a lot of storage space too.
