Best Video Compression Software for Mac to Compress Video without Losing Quality

We google "best video compression software" for various reasons. You have a Creative Webcam 750 and plan to send some family videos by email but find any video taken is much too large. You create a 2-hour movie in MP4 using HitFilm and mean to stream it via Vimeo or YouTube, yet you suffer a failure on account of its 7 GB large file size. You may wanna compress a video on Mac in HD 1080p (about 10 GB) to the minimum size without sacrificing any quality, but no suitable Mac video processing software reaches your expectation.

* Bad quality: The shrinker gives me a highly condensed file, but the quality is not as good. When I import the video with mpeg-4 codec in 1080p, I already lose tons of quality. Any software can reduce video size without sacrificing video quality?
* Compression ratio is not enough: I have a 9GB video and I need to reduce it to the smallest size as possible. I can significantly downsize its file to around 4.27GB at good quality, which is impressive, but still too large for me. If I go further, the video quality becomes unacceptable. How can I properly reduce the video file size to smaller size without much loss in quality? Any compressor suggestion?
* High CPU usage: When I downsize a 4K ultra high-definition video with Handbrake, my CPU runs at 100% and computer gets hot. When I set the priority to lower settings to ease the CPU usage, the video shrinking becomes very slow.

That's quite off-putting. But thankfully, here comes the solid video compression software for Mac to reduce video file size by up to 70% with no noticeable quality loss. The following part will step-by-step illustrate you how to:
