It allows users to reduce video size in various ways, for example, cutting off unwanted parts to shorten your video length, splitting a large video into segments to adapt to social media's size limits, turning video format to a higher compression efficiency ones, like H.264 to HEVC, downscaling video resolution, lowering video bit rate, frame rate etc. Better yet, VideoProc is also fast.

[Video Compression Test] VideoProc's Performance Over Handbrake

Besides VideoProc, Handbrake is also commonly used to compress video size. To tease out the superiority of VideoProc, we've tested to use it and Handbrake to shrink a large-sized 4K MP4 video shot by GoPro to the same settings.

I'm running on my Mid 2011 27-inch iMac with OS X Yosemite, 2.7 GHz Intel Core i5, 8GB 1333 MHz DDR3, Graphics AMD Radeon HD6770M 512 MB.

Apparently, VideoProc gets more video size reduced than Handbrake. And in the same output setting, VideoProc takes 2 minutes 13 seconds to make this 4K UHD video compression done on the iMac (HEVC hardware acceleration is not available on this computer), while Handbrake needs 5 minutes 7 seconds indeed. Both videos look pretty clear, yet the one compressed with VideoProc almost gets 10 times smaller size than Handbrake compressed one. So why not choose VideoProc to reduce video file size dramatically without quality loss.
