Compress 4K - compress large-sized 4K 2160p to 1080p, along with frame rate, bit rate adjustment to reduce 4K UHD video size with 34% compression ratio, greatly saving iPhone space for storing more stuff (movies, photos, music, etc).

You may wonder if the ultra fast speed comes at the expense of quality. The answer is No. MacX developer team constantly optimizes its High Quality Engine, video transcoding algorithm and Auto Copy mode to improve output quality virtually equal to the original one, 98% - 100% quality reserved.

How Does Hardware Acceleration Affect on the Speed

The general video converter mainly relies on its' built-in software decoding and encoding engines to convert 4K UHD videos at limited speed. Things are different to MacX 4K video processing software, for it makes good use of Intel QSV/AMD/NVIDIA (CUDA/NVENC) hardware accelerated processing techs to encode 4K videos to H264, 5X faster than before and 5-8X faster than Handbrake.
