HEVC Syntax & Processor help

[innosia]

Hi all

I am new with HEVC encoding, i am confuse with so many tools out there

ffmpeg encode result in hevc, is that the video format that can be played? How to convert it back to mkv since I want mkv to mkv but smaller size?

Questions
1. What is the command line tools & syntax to convert mkv to mkv (small size)?
2. What processor is needed, my current procie, will it enough?
"intel xeon cpu e3-1220 v2 @ 3.10GHz 3.10GHz"

I just need to encode mkv to mkv with smaller size with minimum quality loss using command line

2- any processor is fine, the more powerful, the faster

1- try the following

ffmpeg -i "C:\Users\admin\Desktop\base.mkv" -c:v libx265 -preset:v slower -c:a copy -x265-params crf=20:deblock=-1 "C:\Users\admin\Desktop\result.mkv"

Use higher or lower crf to suit your desired file size

hi luigizaninoni

how about other tools like x265_64-12bit[gcc].exe
what is the syntax of it

sorry for asking, noob here, quite confuse since there is x265_64-12bit[gcc].exe and also ffmpeg, dunno which one should be use

ffmpeg uses libx265. It doesn't do the encoding on its own. So whether you use ffmpeg or x265 directly, it doesn't matter much
