4 min 5 secs is the right answer. Did you guess it? Besides the unrivalled speed, MacX Video Converter Pro provides one-stop solution to compress, convert, repair, edit & record video at ease. Know more >>
Convert 4K - convert 4K AVC video to H264 to make 4K Ultra HD video uploadable, playable and editable. Also support you to convert any video to H264, HEVC, MP4, etc. 200+ formats.
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).
Edit 4K - trim and cut off unnecessary clips to shorten 4K video duration so as to fast upload 4K camcorder video to YouTube.
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.
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.
Here we take a 30fps 4K Ultra HD video source as an example. When the GPU hardware encoding is enabled on MacX, your 4K video processing will be running at 150fps and your video encoding on this is 5X real time faster than the disabled version. As for Handbrake, it encodes this input source at 18fps, 8X slower than MacX on account of QuickSync/GPU hardware encoding unsupported in Mac version.
Aiming to be a leading digital media company, Digiarty Software, Inc.(MacXDVD) keeps producing a wide range of professional multimedia software apps for Mac, Windows, iOS and Android users since its establishment in 2006.
World's 1st Intel QSV video converter for Mac to convert video 5X faster than Handbrake.
