Hi guys, I was planning to transfer my videos from H264 to H265 currently. But there two things that I am really concerned about: quality and file size. The the size of transferred videos are not as small as what I expected. I mean, I can get 20% of the video size by using H265 on Handbrake but the quality is really unacceptable. I am aiming less than 25% of the original video size without noticeable quality loss. I saw someone from the Internet can really do it. How I can do that? Thanks or that.
There are the video details:

Re: The balance setting for HEVC videos.
An air traffic controller once told me, "Don't worry, I saw this work once".
The people who "got it to work"... what did they get it to work ON? And why have they withheld the secret of perpetual motion (and massive encoding values) from you?
Without information like we'd see in the required log files, it is VERY hard to guess at what you're doing now on what kind of files. It is simple to get 90% reduction of file size for some video types, and hard to get 10% reduction on others.

Whoever you're trying to copy probably had a less efficient source.
