[QUOTE="Stéphane Lenclud, post: 1165641, member: 140174"] I used MakeMKV to rip a Blu Ray and then proceed to use [URL='https://handbrake.fr/']HandBrake[/URL] to perform the video recoding to save disk space. Here I'm sharing some results depending of the CQ selected. The source was a video lasting some 2 hours and 7 minutes.
