Converting H.264 MKV to H.265 MKV Efficiently

I’ve ripped all of my DVD’s and Blu-ray’s to MKV using MakeMKV. Most of my Blu-rays are in H.264 format but some are in VC-1 format. Any program to convert these h.264 MKV videos to H.265 MKV’s to reduce disk space usage without loosing any quality? From someone’s shared tutorial I know that it’s not a hard job as long as to get a professional h.265 encoder. Now in this page, I will share some options to convert H.264 MKV to H.265 MKV with the best quality.

Method 1. Using Handbrake to do H.265 encodes

Step 1: Launch HandBrake, Click on “Source” button, open a single file or a whole video folder you want to convert and wait until HandBrake completes the scanning.

Step 2: Select Output Container as “MKV”.

Step 3: Click on “Video” -> Video Codec -> H.265(x265).

If you are to convert x264 to x265 with reduced file size, just keep constant quality at 20, 21 or 22. This will deliver great quality with acceptable size. Otherwise, 23 will be a great balance between quality and file size especially for 1080p videos.


Step 4: After all the HandBrake H.265 settings, you are good to go by tapping “Start” button on the top and the H.264 MKV to H.265 MKV video conversion will happen.

Limitations of HandBrake for H.265/HEVC Videos:

1. The operation is too complicated and unfriendly for beginners.

2. HEVC takes a WHOLE lot longer to encode compared with H264. Using Handbrake I was sitting at about 24 hours to do a single MKV file (highest quality).
