Downscale 4K to 1080P: It can downscale 4K UHD video to 1080p/720/560/480p with optimal quality reserved but shrinking 4K video file size greatly.ģ.

That means you can directly transcode MP4 H.264 to MP4 H.265/HEVC and even upscale HD 1080p to 4K without manually adjusting parameters.Ģ.

Profiles for 4K MP4 and HEVC MP4: MacX Video Converter Pro is only 4k video converter that adds direct profiles for 2k MP4, 4K MP4, HEVC MP4 and HEVC MKV. Why MacX is the best choice to convert 4K H.264 to H.265/HEVC?ġ. Is it impossible to convert 4K H.264 to 4K H.265 swiftly? The answer is YES! You can try MacX Video Converter Pro - the best HEVC/ H.265 decoder and encoder. That's why many users complain it takes abnormally 20 hours to complete a 5 min 4K video converting from H.264 to H.265 and ask for a way to speed up 4K H.265 encoding from H.264. As a result, it will take more time to complete the process of 4K H.264 to H.265 transcoding, especially when on a lower-configured computer. It's worth noting that the 4k video encoding in H.265/HEVC consumes up to 8-10x more computer power than H.264. Recommended Software: MacX Video Converter Pro User rating: ★★★★★ 5.0/4.

How to Compress 4K Video Size from H.264 to H.265 at Fast Speed And many people, if saved a lot of 4K video downloads in H.264, will prone to convert them to 4K H.265, so that you can accommodate the 4K videos without using up much storage space and consume less bandwidth data required for sharing over networks. With the added emphasis on 4K content, the new HEVC/H.265 rises to the throne. According to Apple, HEVC encoding performs a significantly enhanced coding efficiency and yields an up to 50% reduction in file size compared to H.264 encoding, but the 4K videos in H.265 typically shows fewer compression artifacts and offer smoother playback than the 4K videos encoded in H.264. This is because H.265, officially named as HEVC (High Efficiency Video Coding), is so far the video compression standard, doubling the data compression ratio at the same level of video quality. While better compression, such as decoding 4K H.264 to 4K H.265, manages to output video the same as original yet make the amount of data less, without sacrificing any quality. from MKV to FLV or WMV is usually called heavy 4k video compression, it keeps the 4k resolution technically the same, but the image can be weirdly noisier or have distracting artifacts.
It's know to all lowering video parameters like resolution will shrink the file size to a great extent, but this happens at the expense of video quality degradation.
